First off, what is a disclosure?
It's the intentional or unintentional release of protected or private/confidential information to an untrusted environment or to unauthorized individuals.
Process for reporting a disclosure
- Remove the disclosed information as soon as possible
- Immediately report the incident to the Information Security Office
- Notify your supervisor
Now that your CalNet account has been unlocked, you must reset your passphrase as follows:
Select "Forgot my CalNet ID / Passphrase"
Enter your Student, Employee, or Affiliate ID NUMBER, or recovery email address
Confirm that you are not a robot by selecting all of the applicable images
Once you receive the email to reset your passphrase, enter your Student, Employee, or Affiliate ID number again to set a new passphrase
Because your exposed CalNet passphrase puts the security of your personal data at risk, you must also complete each of the following tasks after you reset your passphrase.
If you are a UC Berkeley employee, confirm that no changes have been made to your Direct Deposit account. From a safe and malware-free computer, access the Direct Deposit link from https://ucpath.berkeley.edu/ or call Payroll (510-642-1336).
Confirm that your email is not being redirected to any account you do not recognize via unauthorized email forwarding, and make sure there are no filters you did not create (e.g. send all <my bank emails> to my Trash folder.
How to forward emails from bMail account: https://support.google.com/mail/answer/10957?hl=en
How to use filters in bMail:
Review bMail account logs and sign out of active sessions
Log into your bMail account
In the very lower right corner, under "Last account activity" click the "Details" link
This will show the last few connections to your account; review for unknown logins
On the same page, click the large gray button "Sign out of all other web sessions"
Re-secure your Recovery Email Address by changing the password. The recovery email address is a non-"berkeley.edu" email address attached to your CalNet account. Resetting the password on this account helps ensure that it is also not compromised.
Recreate your bConnected Google Key. If you had a Google key set, it has been scrambled. Create a new one using the Manage My Keys application: https://idc.berkeley.edu/mmk/ or contact bConnected support: email@example.com or 510-664-9000 press 1 and follow the prompts.
Review your CalNet 2-Step devices to make sure no changes have been made. Log in to mycalnet.berkeley.edu, click on Manage 2-Step Verification, perform a 2nd 2-Step to see the Device Control Panel, and review your devices, there. See: https://calnetweb.berkeley.edu/calnet-2-step
Units interested in detailed information about IS-3 controls; roles and responsibilities; and implementation tools from the UC Systemwide Policy Office can contact ISO at firstname.lastname@example.org to request access to the systemwide materials.
Please fill out this request form only if you have not already been in contact with campus IT professionals (either through your department or IT Client Services) regarding the upgrade of your current Windows 7 computer, purchase of a new computer, or security exception application.
- Begin by backing up your files. You can do this to a local device or move your data from the computer to servers or cloud-based platforms. Please note that location is dependent on the protection level of the data you have: UC P1 (formerly UCB PL0) and UC P2/P3 (formerly UCB PL1) data can be stored on Google Drive and Box. UC P4 (formerly UC PL2) data may only be stored on Calshare
- Confirm that any software (outside of the standard MS Office, Chrome, Adobe Acrobat) is compatible with Windows 10 and that you have the installation files and activation keys needed
- Go to: https://software.berkeley.edu/microsoft-os and download your desired operating system.
Exceptions are allowed only if the system cannot be upgraded and depending on the data classification level and the amount of data of that type. Submit your security exception request by November 1, 2019, to allow time to implement mitigations needed before End of Life.
If you are running Windows 7 you are unsupported and out of compliance with campus policy.
What happens next:
- Feb. 1, 2020 - ISO notifies Windows 7 systems users to disconnect from the campus network
- Mar. 1, 2020 - ISO blocks Windows 7 devices seen on the campus network
Please note: In the event that a Windows 7 exploit is released before Mar. 1, ISO reserves the right to immediately block any vulnerable device per the Blocking Network Access Policy.
Exceptions are allowed only if the system cannot be upgraded and depending on the data classification level and the amount of data of that type. Learn more about security exceptions at our Exception Process for Windows 7 End of Life (EOL) page.

No. Information Security and Policy does not "certify" applications. A Pass or Fail grade is intended to indicate whether or not an application meets the campus minimum security requirements for application security at the time at which it was assesssed.
An application security assessment is intended to find the most critical and high risk vulnerabilities; however, the assessment process is often accelerated due to time and resource constraints meaning all vulnerabilities may not be discovered in a single assessment.
Remediation due dates are generated based on the risk and the breadth of the vulnerability. Due dates can be negotiated with the Information Security Office at the time of disclosure. For example, some due dates may be changed for reasons like:
- Reliance upon a vendor to implement a fix for a discovered vulnerability
- Development time
- Retirement of a vulnerable portion of an application
Ultimately, it is the responsibility of the application owner to make or coordinate best efforts to remediate and/or adequately mitigate the risks in a timely fashion.
No. ASTP assessments only measure compliance with campus minimum application security requirements. Though, it should be noted that achieving compliance with campus standards will lay a lot of ground work for meeting PCI, HIPAA, CPHS, or other external standards. The campus Minimum Security Standards for Electronic Information (MSSEI) is based off the SANS Top 20 Critical Controls, so there is some overlap with external standards.
Currently, applications handling UC P4 data (formerly UCB PL2) should plan for an application security assessment once every two years. However, scheduling will depend on available resources and other factors such as how drastically an application has changed since the prior assessment.
All Information Information Security Office scanning is initiated from the following subnet:
Scanning will be initiated only from IP addresses with DNS hostnames in the "security.berkeley.edu" subdomain. All ISO scanners have hostnames that reflect their role, such as "sns-campus-scanner-1.security.berkeley.edu".
If you detect scanning activity and are unsure if an ISO scanner is the source, please contact email@example.com for verification.
Credentialed scans are scans in which the scanning computer has an account on the computer being scanned that allows the scanner to do a more thorough check looking for problems that can not be seen from the network. Examples of the sorts of checks that a credentialed scan can do include checks to see if the system is running insecure versions of Adobe Acrobat or Java or if there are poor security permissions governing a service. Information Security Office (ISO) runs Nessus scanners that are capable of running these credentialed scans; however, without accounts on the local machines, we are unable to use this functionality. With this in mind, ISO will create accounts on one of the Nessus scanners for departmental security administrators to do their own credentialed scans. In order to use the ISO scanners to perform a credentialed scan of a Windows system, the following settings are required by Nessus:
- The Windows Management Instrumentation (WMI) service must be enabled on the target.
- The Remote Registry service must be enabled on the target or the credentials used by Nessus must have the permissions necessary to start the remote registry service and be configured appropriately.
- File & Printer Sharing must be enabled on the system to be scanned.
- An SMB account must be used that has local administrator rights on the target. A non-administrator account can do some limited scanning; however, a large number of checks will not run without these rights. According to Tenable, the company behind Nessus, in Windows 7 it is necessary to use the Administrator account, not just an account in the Administrators group. ISO is currently in the process of testing this and looking for potential workarounds.
- Ports 139 (TCP) and 445 (TCP) must be open between the Nessus scanner and the computer to be scanned. Information on what IP block to open in the firewalls can be found here: What is the source network for security scans conducted by Information Security and Policy?
- Ensure that no Windows security policies are in place that blocks access to these services. Two common problems are the SEP configurations that block off the scanners even after the scanners is authenticated and a network access model that sets network access to "Guest only" permissions (see below for information on changing this).
- The default administrative shares (i.e. IPC$, ADMIN$, C$) must be enabled (AutoShareServer = 1). Since these are enabled by default and can cause other issues if disabled, this is rarely a problem.
To check if a system has a "Guest only" sharing and security model go to the Control Panel, open "Administrative Tools," and then "Local Security Policy". In that window go to Local Policies --> Security Options --> Network access: Sharing and security model for local accounts. On some Windows installations, this is set to "Guest only - local users authenticate as Guest" by default. If this is the setting on your box, you will need to change it to "Classic - local users authenticate as themselves".
PLEASE NOTE: Some of the settings above may, in some environments, actually decrease the security of a system. If this is the case, once the credentialed scan is performed, it is advisable to return the system to its previous state.
There are four privilege levels for any member of a security contact:
View-only: can view registration information.
Device: can make changes to Device registrations.
IP Information: can claim subnets, request IP Addresses, register subdomains and offsite hostname. Can register RD Applications. Can also make changes to Device registrations.
Admin: includes Device and IP Information privileges. Can also make profile and membership changes to the security contact itself.
A Group Security Contact (GSC) is created by a Department Security Contact (DSC) when a separation of responsibilities is needed. Each DSC will have an orgnode set, and the GSC will be associated to the department via its parent, the DSC.
A Group Security Contact can be used to help departments separate devices into sets that receive (or do not receive) IT support from a Service Provider Security Contact (SP SC). Additionally, when responses to security incidents is the responsibility of different groups (e.g., a research lab within a larger department, student systems vs. an administrative one) a DSC can create a GSC to receive targeted notices.
Service Provider Security Contacts (SCs) are a special purpose security contact. As a service provider, they don't have registered network assets, but they are flagged within NetReg as providing support for another SC. For example, the Service Provider SC might register devices for the Client SC. Service Provider SCs have "device-based" privileges with the Client SC; they can create, edit and delete devices from the Client SC.
Service Provider SCs can be grouped or departmental. Notifications about security events (compromises, vulnerabilities, etc.) will go to members of both Service Provider and Client SCs.
Security notices are routed based upon the most specific registration information available in NetReg.
For example, if an IP address has a registered security contact, the security notice is sent to that contact. If there is no specific IP address registration then the notice is sent to the security contact that claimed the subnet. Notices will also be sent to:
• the registrant contact role's service provider if any
• its departmental / parent contact role if any,
• and any contact roles that have 'CC SC' status for the IP address
OR, if the IP addresses is for a DHCP device (in the LIPs subdomain) the security notice will go to whomever was using the address at that time (to CalNet ID).
NetReg supports IPv6.
DHCP registration was added to NetReg in Oct 2015. For instructions on how to use NetReg to register devices for use with the Campus DHCP Service, please visit the "Register Devices" page in the NetReg documentation.
Overlap is not allowed in NetReg. If two departments share a subnet, during the data conversion the department who claims the most IP addresses for that subnet will get the entire subnet. The other department will get individual IP addresses.
Additionally, one SC will own and be primarily responsible for an IP address, although other SCs may be provided shared notification..
For complicated situations, e.g., where two different groups are responsible for systems on a subnet, a Contact Role created just for that shared responsibility might be the best solution.
NetReg is designed to facilitate communication between security contacts for the purpose of keeping network registration information up-to-date, without revealing private security mailing list addresses or allowing out-of-band communication between security contacts on other issues.
If you claim the entire subnet you can view the names of the security contacts that claim individual IP addresses on that subnet. If you only claim an individual address then you cannot see the names of the other security contacts.
No. Requests for IP addresses, CC IP Address status are handled via the request/approve/deny process. Any other communication issue can be handled by contacting ISO.
There are three types of email generated by NetReg:
- FYI emails: These emails are rolled up into a single digest which is sent once per day. Users can opt out of receiving the digest by setting "Receive FYI digest" to off. However, at least one Security Contact (SC) member should continue to receive them.
- Notices of "requests to approve or deny": These are sent within 5 minutes from when the request is made via the NetReg application, and are sent to all members in the SC. Users do not have the option to opt out of receiving these.
There are 4 kinds of "requests to approve or deny" which users may receive:
- Request to transfer an individual IP address. (Note: the request can be initiated by either the SC that currently claims it (request to give), or by the SC that wants it (request to take).)
- Request for CC SC status for an IP address
- Request for membership within a SC
- Request to create of a group SC within a department SC
- Notices to "outside" entities (i.e., ISO RT ticketing system, Hostmaster, or IT Policy): These are initiated by NetReg backend processes or sometimes by NetReg users and are cc'd to any relevant SC's membership.
For example, when a request is made for a new departmental SC the request will go to the Information Security Office (ISO). ISO will conduct an intake process and will create the DSC.
You've received the message because Netreg has encountered a mismatch between the security contact that claimed an IP address (individually or by subnet) and the security contact that registered a subdomain.
(Note: In Netreg the assignment of a subdomain enables the transfer of IP address responsibility to the right party, but does not assign security contact responsibility).
For example, if security contact A registers a subdomain xyz.berkeley.edu and another security contact B claims subnet a.b.c.0/24 and there is a set of hostnames defined in DNS:
security contact A and B will each get a message suggesting that the IP addresses be transferred from B to A.
Either security contact can initiate the transfer: Security contact A can 'request to take'; B can 'request to give'.
If the other party agrees and approves the transfer then B ends up with the subnet and A has 3 individual IP records out of that subnet because of its subdomain registration.
Remember: NetReg does not automatically make the transfer because there may be alternate solutions to resolve the discrepancy. In the above example, security contact A could relinquish the IP addresses, or have their DNS hostname changed to something not in the xyz subdomain.
You are receiving this "IP address to transfer" message so that you can choose the best solution.
Department and Group Security Contact roles can register devices for Fixed IP address assignment – where a device always gets the same IP on its primary subnet, but a Dynamic IP on any other subnet – provided that the contact role has a registered subnet, with available IP address space, and a registered subdomain.
For details about registering devices for Fixed IP address assignment, please review the "Register Devices" page in the NetReg documentation.
Yes. Security Contacts can assign a Dynamic DNS (DDNS) hostname to a device when using Dynamic IP addressing (DDNS is not available for devices registered with a Fixed IP address assignment). Please review the "Register Devices" page in the NetReg documentation for details.
Note: Dynamic DNS hostnames will be reviewed by the campus hostmaster and changed if inappropriate.
The Information Security Office (ISO) takes privacy issues very seriously, and we use the same approach for balancing security and privacy for protected data hosts as for all hosts on campus. Monitoring of systems occurs through two methods, monitoring of network traffic crossing the campus border and vulnerability scanning of hosts on the campus network. The methods used to do this are similar for all hosts on the campus network.
The enhanced services for protected data hosts are:
- More frequent scanning -- network vulnerability scans for NetReg registered hosts occur nightly
- A greater range of intrusion detection signatures are reviewed with notifications sent to the security contact
- Elevated responses to alerts – ISO staff are alerted immediately and will attempt to reach an administrator as soon as possible.
- Longer retention of network data for future analysis if a breach is confirmed -- this can help to confirm if an attacker was able to access the protected data during the breach incident
A "vendor" or "3rd-party service provider" is an entity (e.g., a person or a company), separate from the University, that offers something for sale. The typical types of vendor services that require an ISO vendor security assessment are technologies used to store, process, and/or transport protected data on behalf of the University, such as:
- Software as a Service (SaaS) providers - companies that provide hosted application services (e.g., Google bmail)
- Infrastructure as a Service (IaaS) providers - companies that provide hosted data storage or processing services (e.g., Amazon AWS)
These types of vendors are required to meet the same campus policy standards for the protection of protected data that is required for applications and services that are managed by internal campus IT resources.
The Vendor Security Assessment Program is intended to ensure that service providers who handle UC P4 (formerly UCB PL2) data on behalf of the University meet campus security policy requirements. This is achieved in two ways:
- By evaluating the vendor's security controls in comparison to campus policy.
- Ensuring that the UCOP Data Security & Privacy Appendix is included in the vendor contract to provide baseline protection for the University in the event of a data breach.
The roles that are typically involved in participating with a vendor security assessment include the following:
|Resource Owner or Proprietor||Campus unit representative who has overall responsibility for the application (e.g., budgeting and resource allocation).|
|Implementation Project Manager||Unit member responsible for the roll-out of the application or service, including (but not limited to) vendor selection, contract specifications, configuration, process-flow design, personnel training, etc.|
|UC Buyer||Representative in the UC Procurement department responsible for the vendor contract negotiation.|
|Vendor Representative||Staff member of the service provider responsible for completing the Vendor Security Assessment Questionnaire. Ideally, this person is affiliated with the IT department and is knowledgable regarding the vendor's security framework. Often times, the person in this role is a Sales or Customer Support Representative who facilitates communication between the vendor's IT staff and the ISO Assessor.|
|ISO Assessor||A member of the ISO analysts team assigned as the primary assessor responsible for the engagement with the unit.|
There are several 3rd-party vendor services that are readily available to campus that have been approved for UC P2/P3 (formerly UCB PL1) or UC P4 (formerly UCB PL2) data. Campus units that adopt these 3rd-party services for the purpose of storing and sharing covered data can be assured that these vendors meet campus policy requirements.
Campus units that utilize these services for the handling of protected data should keep in mind that careful configuration and management of these applications is required to meet campus policy standards.
UC P4 (formerly UCB PL2) Approved Services
- CalShare, a web-based document management and collaboration system utilizing Microsoft SharePoint.
- The Imagine document imaging and workflow service is a campus service with the core purpose to provide automated workflows and document management and storage and can be integrated with other campus systems if needed.
UC P2/P3 (formerly UCB PL1) Approved Services
- The bConnected suite of collaboration services, including Google Apps for Education (bMail, bCal, bDrive)
- bCourses Project Sites
Please visit the bConnected website to learn more about the MSSEI protection level ratings for each of these products: https://bconnected.berkeley.edu/collaboration-services
Units can ensure that 3rd-party service providers meet the campus data security policy requirements for the handling of UC P2/3 (formerly UCB PL1) data through the following actions:
- Be sure to include the UCOP Data Security & Privacy Appendix, required for all UC contracts involving 3rd-party access to protected data, without edits, in the service provider contract. This ensures baseline protection for the University in the event of a data breach, including:
- Service provider compliance with applicable laws (e.g., FERPA, HIPAA), regulations and campus policy.
- Requirements for a vendor information security plan and breach reporting process.
- Adequate cyber-insurance to cover the cost of investigating and responding to a breach.
- Notify the service provider that by signing off on the Data Security & Privacy Appendix, they are obligated to abide by campus policy, including adherence to the requirements of the UC Berkeley Minimum Security Standard for Electronic Information (MSSEI) policy for the protection of UC P2/3 (formerly UCB PL1) data.
Although there is less bargaining power with the service provider to address security concerns after the contract has already been signed, it is still a good idea to perform a vendor security assessment for service providers who are handling UC P3 or P4 (formerly UCB PL2+) data:
- If the overall risk level is acceptable, the unit is assured that the vendor meets campus policy for the protection of UC P3 or P4 (formerly UCB PL2+) data.
- If the overall risk level is High or Critical, it may be necessary to postpone or suspend the service until these issues have been addressed.
Vendors may be more inclined to participate in a security assessment after the contract has been signed, but before the service has been initiated - as billing often does not begin until services have started.
For VSAP reports with an overall acceptable risk rating, any medium-level risk findings identified in the report should be discussed with the vendor during the next contract renewal period.
For all UC contracts involving third-party access to covered data, the University of California Office of the President (UCOP) requires the inclusion of the Data Security and Privacy Appendix. The appendix establishes baseline protection for the University in the event of a data breach. Campus units that engage with service providers to handle covered data must ensure the appendix is included in new contracts without edits.
For VSAP engagements that have been initiated after the contract has been approved, and the UCOP appendix has been omitted, the final assessment report will include contract-related risk findings. These findings are generally of a Critical risk nature, e.g.:
- No guarantee of service provider compliance with applicable laws (e.g., FERPA, HIPAA) or campus policies for the protection of covered data.
- The absence of requirements for a vendor information security plan and breach reporting process.
- Inadequate cyber-insurance to cover the cost of investigating and responding to a breach.
In these cases, the unit may be required to suspend the use of the service until the contract issues have been resolved with the vendor.
To request a Vendor Security Assessment Program evaluation for a PL2 system that is vendor managed, review the Details of the Vendor Security Assessment Program and then send an email to firstname.lastname@example.org.
Please include the following information:
- Name of the unit requesting VSAP service
- Project Lead contact information
- UC Provisioning Representative contact information (if applicable)
- Name of third-party vendor/product/service
- Service description
- List of protected data elements that are known to be processed, stored, or transmitted by the service provider (see the UC Data Classification Standard for details)
- Estimated number of records containing PL2 data

Security best practices, as well as campus Minimum Security Standards for Network Devices (MSSND), require the use of supported software for which the vendor will make security updates available in a timely fashion. As vendors are unable to support all previous versions of software, older programs are dropped from support and must be upgraded or removed from the network. It is especially important to be aware of your operating system “end of life”, as major upgrades often require time and planning.
Microsoft publishes current lifecycle information for Windows operating systems. If your version of Windows is past the date for extended support, or not listed, your operating system is not supported and you must retire the system or upgrade to a supported version of Windows. When planning for department equipment purchases and upgrades, be aware of any upcoming “end of life” dates for your version of Windows.
Mac OS X
While Apple does not officially acknowledge the end of support for Mac OS X operating systems, past experience shows that security updates addressing critical vulnerabilities are only released for the current and one previous version of Mac OS X. When Apple releases security updates for Mac OS X, operating systems with vulnerabilities that are not patched by Apple will be considered unsupported.
Mac OS X users should plan on upgrading their operating systems regularly as Apple releases new versions. We recommend updating to either the latest version, or one previous version, no more than 90 days after a new version is released.
A list of current security updates can be found on the Apple Support site: https://support.apple.com/en-us/HT20122
Other Operating Systems
Check with your vendor to confirm whether or not your version is still under support and receiving security updates for known vulnerabilities. Operating system vendors often publish lifecycle information to assist customers with upgrade planning:
MSSND Exception Requests
If your operating system is not currently supported, and you cannot immediately upgrade to a supported release, you must request a policy exception to keep the machine connected to the campus network. Your request should include details such as:
- Why you cannot upgrade your current unsupported operating system
- Timeframe for upgrading or retiring the system
- Full inventory of software running on the system
- Expected use of the system including all network use
- Firewall rules and other security controls mitigating the risk
The distinction here is that just because there is a contract in place with a supplier doesn't mean that it is appropriate for all use cases.
An example is our Google agreement which will meet the overwhelming majority of our needs in the e-mail/calendar space, but that is not HIPAA compliant and as such is not a good fit for use cases where Protected Health Information is in play. For assistance with IT policy questions, contact email@example.com.
By engaging with a service provider, you have the responsibility as the Resource Proprietor for ensuring compliance with laws, regulations and policies, including standards (UC Business Finance Bulletin IS-2 and IS-3).
For example, if notice-triggering data is involved, the service (whether on or off campus) must meet the protective measures defined in the campus Minimum Security Standard for Electronic Information.
Information that is subject to state or federal regulations will have use and disclosure restrictions that must be maintained. Student records are protected by FERPA regulations. Medical records are protected by HIPAA, FERPA, and state laws.
The Resource Proprietor, in consultation with the Resource Custodian, is responsible for determining the level of risk (subject to law, regulation, and policy) and ensuring the implementation of appropriate security controls to address that risk. This puts responsibility for evaluation of the service's security controls (e.g., hardening, patching and monitoring) in the hands of the Resource Proprietor. Although not directly applicable to services outside of the campus network, the campus Minimum Security Standard for Networked Devices provides a useful set of baseline security requirements.
For evaluating cloud service providers that handle PL2 data on behalf of the University, the Information Security Office offers the Vendor Security Assessment Program (VSAP). The VSAP is intended to ensure that campus third-party service providers adhere to the same baseline level of security practices required for campus systems and applications that contain protected information and are managed and maintained by internal campus resources.
To request a VSAP evaluation for a PL2 system that is vendor managed, review the Details of the Vendor Security Assessment Program and then send an email request to firstname.lastname@example.org (link sends e-mail).
If there are particular services or types of services that you believe would add significant value, please contact David Willson (email@example.com).

Phishing is a type of attack carried out in order to steal usernames, passwords, credit card information, Social Security numbers, and other sensitive data by masquerading as a trustworthy entity. Phishing is most often seen on campus in the form of malicious emails pretending to be from credible sources such as a UC Berkeley colleague, technology department, or financial organizations related to the university.
By tricking campus users into giving away their information, attackers can:
- Steal money from victims (modify direct deposit information, drain bank accounts)
- Perform identity theft (run up charges on credit cards, open new accounts)
- Send spam from compromised email accounts
Use your credentials to access other campus systems, attack other systems, steal confidential University data, and jeopardize the mission of the campus
The goal of most Phishing emails is to trick you into visiting a web site in order to steal your CalNet credentials. Attackers will set up web sites under their control that look and feel like legitimate web sites. Often the Phishing emails will have an immediate call to action that demands you to "update your account information" or "login to confirm ownership of your account". If you enter your CalNet credentials into these illegitimate web sites you are actually sending your CalNet username and password directly to the attackers.
The first rule to remember is to never give out any personal information in an email. No institution, bank or otherwise, will ever ask for this information via email. It may not always be easy to tell whether an email or website is legitimate and phishing emails are using social engineering tactics to make create sophisticated scams.
- In the body of an email, you might see questions asking you to “verify” or “update your account” or “failure to update your records will result in account suspension.” It is usually safe to assume that no credible organization to which you have provided your information will ever ask you to re-enter it, so do not fall for this trap.
- Any email that asks for your personal or sensitive information should be seriously scoured and not trusted. Even if the email has official logos or text or even links to a legitimate website, it could easily be fraudulent. Never give out your personal information.
Phishing attacks are a constant threat to campus and are becoming increasingly sophisticated. Successful Phishing attacks can:
- Cause financial loss for victims
- Put their personal information at risk
- Put university data and systems at risk
We encourage the UC Berkeley community to take an active role in protecting themselves against phishing attacks. Use our helpful tips in our Fight the Phish campaign to recognize and report phishing attacks.
- If you are worried about an account, call the organization which maintains it (like your bank)
- Check the email address—does it really match the text of the email? Does it match the legitimate email of the organization it is supposed to be tied to?
- Check the security certificate of any website into which you are entering sensitive data. They should usually begin with https:// Some browsers will display padlock symbols in the address and status bars. Anything on a website saying it is safe can be falsified and is not verified by the browser you are using, and so shouldn’t be trusted
- Keep your software current
- Install antivirus software
- Being tricked to giving up your credentials at a real-looking but scam website (AKA Phishing)
- Malware or other compromises of your device which installs software designed to run in the background and steal passphrases
- Re-using CalNet credentials for non-UCB websites, and the non-UCB websites are hacked and all credentials exposed
However, a couple of tell-tale signs of credential compromise are:
- Your colleagues and friends have received unexpected messages from your email account (spam or additional Phishing emails)
- You suddenly cannot login with your CalNet credentials because an attacker has changed your passphrase
- Know how to evaluate whether websites asking for your passphrase are legitimate. When in doubt, ask by sending an email to firstname.lastname@example.org or contacting ITCS at 510-664-9000
- Only use devices that are up-to-date. This means patches for all software are installed as soon as the patches become available, that the browsers are configured for maximum security, and the device otherwise meets the campus Minimum Security Standards for Networked Devices.
- Do not reuse your CalNet passphrase for other websites
If in doubt regarding the security of your CalNet account, change your CalNet passphrase!
When changing your CalNet passphrase, be sure to do so from a machine you believe is not infected by malware or otherwise compromised. Anti-malware and antivirus scans should result in a "clean" report (no infections) for the machine you intend to use to change your CalNet passphrase from.
Note: The Information Security Office is sometimes informed when passwords associated with UC Berkeley accounts are exposed in public forums or discovered during breach investigations. In these cases, we may test the exposed passwords to see if they are valid CalNet passphrase. If the passphrase is validated, it will be scrambled immediately and the account deactivated until the account owner is contacted to create a new passphrase. This testing is done only for validation purposes and is not used for access to the account holder's email or other electronic services.
Please see Why did I get a Credential Exposure notice and what should I do? for information on what to do if you receive an ISO Security notification for exposure of your account credentials.
If you believe your CalNet credentials have been compromised, you must reset your CalNet passphrase immediately.

Reporting suspicious emails can dramatically reduce the duration and impact of an active phishing attack.
Using the bMail web interface:
- Open the message
- To the right of 'Reply' arrow, select 'More' (typically denoted with three vertical dots)
- Then 'Report phishing'
Reporting through Google allows the email to be blocked from further attacks against and may prevent others from falling victim to the attack.
If you are unable to log into bMail, forward the message to firstname.lastname@example.org or call the ITCS Service Desk at 510-664-9000.
No. Phishing attacks can also occur through phone calls, texts, instant messaging, or malware on your computer which can track how you use your computer and send valuable information to identity thieves. It is important to be vigilant at all times and remain suspicious of sources that ask for your credentials and other personal information.
As an employee of UC Berkeley, any information you create or receive during your employment that has anything to do with the business of UC or the Campus belongs to the Regents. Whether it is information stored in your paper files, on your computer, voice messages, portable media, home laptop, or another account or device used by you, the information is Regential property and must be created and managed according to policy.
Any personal information you may accumulate during your employment belongs to you. You are responsible for the management of your own information. This means at a minimum that if you move location, transfer to a new position, or separate from University employment you must take your personal information with you. Any personal information left behind will be treated in the same manner as any tangible personal property. It will be disposed of according to the campus procedure.
FERPA, shorthand for the Family Educational Rights and Privacy Act, was enacted by Congress in 1974 [20 U.S.C. 1232g]. This legislation gives parents of minor students, and students who are over 18, the right to inspect, correct, amend, and control the disclosure of information in education records. It obliges educational institutions to inform parents and students of their rights and to establish policies and procedures through which their rights can be exercised.
FERPA gives students of any age enrolled in a university or college the right to give or withhold consent for the educational institution to use or disclose personal information about them. There are a number of exceptions to this general right. The main one is that institutions may use student information for legitimate business purposes. Requests to use or disclose UC Berkeley student information are approved by the Registrar who is the authorized data steward for all student information.
Authorization to access electronic communications, with or without consent, is coordinated through the the Campus Privacy Officer, Office of Ethics, Risk and Compliance Services:
Employees have a standard 90-day grace period after they have separated from UC Berkeley, during which they can access limited campus services, such as bMail. In rare cases, a department may want to request early termination of a former employee’s CalNet or Berkeley email (bMail) account before the end of the standard 90-day grace period.
Departments can contact email@example.com to discuss how to deactivate employee (including volunteer and affiliate) CalNet or bMail accounts immediately or otherwise earlier than the normal grace period.
Forms and Process:
- For early disabling of a separated employee’s access, download the Request for Exceptional Disabling of CalNet Account form below for information and instructions. This form is intended to be used for emergency early CalNet account termination. Signed approval by an authorized departmental official is required.
- If the account suspension is temporary and the employee may eventually return to their position, download the Request for TEMPORARY Disabling of CalNet ID or bMail Account form below for information and instructions. This action is for exceptional circumstances only and must be approved by the employee's Department, Human Resources, and Campus Counsel.
- A scanned image of the printed form (with signature) may be submitted by email in lieu of a hard-copy.
Ransomware is a type of malicious software that infects a computer and restricts users’ access to it until a ransom is paid to unlock it. Ransomware variants have been observed for several years and often attempt to extort money from victims by displaying an on-screen alert. Typically, these alerts state that the user’s systems have been locked or that the user’s files have been encrypted. Users are told that unless a ransom is paid, access will not be restored. The ransom demanded from individuals varies greatly but is frequently $200–$400 dollars and must be paid in virtual currency, such as Bitcoin.
Ransomware is often spread through phishing emails that contain malicious attachments or through drive-by downloading. Drive-by downloading occurs when a user unknowingly visits an infected website and then malware is downloaded and installed without the user’s knowledge.
Crypto ransomware, a malware variant that encrypts files, is spread through similar methods and has also been spread through social media, such as Web-based instant messaging applications. Additionally, newer methods of ransomware infection have been observed. For example, vulnerable Web servers have been exploited as an entry point to gain access to an organization’s network.
The authors of ransomware instill fear and panic into their victims, causing them to click on a link or pay a ransom, and users systems can become infected with additional malware. Ransomware displays intimidating messages similar to those below:
- “Your computer has been infected with a virus. Click here to resolve the issue.”
- “Your computer was used to visit websites with illegal content. To unlock your computer, you must pay a $100 fine.”
- “All files on your computer have been encrypted. You must pay this ransom within 72 hours to regain access to your data.”
Ransomware not only targets home users; businesses can also become infected with ransomware, leading to negative consequences, including
- temporary or permanent loss of sensitive or proprietary information,
- disruption to regular operations,
- financial losses incurred to restore systems and files, and
- potential harm to an organization’s reputation.
Paying the ransom does not guarantee the encrypted files will be released; it only guarantees that the malicious actors receive the victim’s money, and in some cases, their banking information. In addition, decrypting files does not mean the malware infection itself has been removed.
Infections can be devastating to an individual or organization, and recovery can be a difficult process that may require the services of a reputable data recovery specialist.
US-CERT recommends that users and administrators take the following preventive measures to protect their computer networks from ransomware infection:
- Employ a data backup and recovery plan for all critical information. Perform and test regular backups to limit the impact of data or system loss and to expedite the recovery process. Note that network-connected backups can also be affected by ransomware; critical backups should be isolated from the network for optimum protection.
- Keep your operating system and software up-to-date with the latest patches. Vulnerable applications and operating systems are the targets of most attacks. Ensuring these are patched with the latest updates greatly reduces the number of exploitable entry points available to an attacker.
- Maintain up-to-date anti-virus software, and scan all software downloaded from the internet prior to executing.
- Restrict users’ ability (permissions) to install and run unwanted software applications, and apply the principle of “Least Privilege” to all systems and services. Restricting these privileges may prevent malware from running or limit its capability to spread through the network.
- Avoid enabling macros from email attachments. If a user opens the attachment and enables macros, embedded code will execute the malware on the machine.
- Do not follow unsolicited Web links in emails. Refer to the Phishing resources found on this website for more information.
Individuals or organizations are discouraged from paying the ransom, as this does not guarantee files will be released. However, the FBI has advised that if Cryptolocker, Cryptowall or other sophisticated forms of ransomware are involved, the victim may not be able to get their data back without paying a ransom.
Signs your system may have been infected by Ransomware:
- Your web browser or desktop is locked with a message about how to pay to unlock your system and/or your file directories contain a "ransom note" file that is usually a .txt file
- All of your files have a new file extension appended to the filenames
- Examples of Ransomware file extensions: .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc, .vvv, .xxx, .ttt, .micro, .encrypted, .locked, .crypto, _crypt, .crinf, .r5a, .XRNT, .XTBL, .crypt, .R16M01D05, .pzdc, .good, .LOL!, .OMG!, .RDM, .RRK, .encryptedRSA, .crjoker, .EnCiPhErEd, .LeChiffre, .keybtc@inbox_com, .0x0, .bleep, .1999, .vault, .HA3, .toxcrypt, .magic, .SUPERCRYPT, .CTBL, .CTB2, .locky or 6-7 length extension consisting of random characters
Responding to a Ransomware Infection
What to do if you believe your system has been infected with ransomware
1. Disconnect From Networks
- Unplug Ethernet cables and disable wifi or any other network adapters.
- Put your device in Airplane Mode
- Turn off Wi-Fi and Bluetooth
This can aid in preventing the spread of the ransomware to shared network resources such as file shares.
2. Disconnect External Devices
- USB drives or memory sticks
- Attached phones or cameras
- External hard drives
- Or any other devices that could also become compromised
3. Report the Incident
It is important that incidents are reported as early as possible so that campus can limit the damage and cost of recovery.
- Your service contains printers and workstations only.
- You don't have any custom rules.
- You don't have technical staff who can configure your firewall rules.
- Your security needs are not extensive.
Your subnet(s) hosts servers and services used outside the firewall.
You host sensitive data.
You have regulatory or contractual obligations to safeguard data that resides on your network.
Restricting traffic based on malicious content or destinations known to be malicious is unacceptable to the users on your subnet.
You don’t need to write your own firewall rules.
You don’t need to define security profiles.
Increased security using profiles that block systems from connecting to or receiving traffic from known bad addresses
Malicious content (spyware, attempts to exploit known vulnerabilities, etc.) will be stopped by the firewall
This service should not be used if you store restricted data.
Rules and profiles in the shared firewall are not customizable.
The only services on the protected side of the firewall that can be accessed from the unprotected side are printing and remote desktop services. These services can only be accessed from non-Calvisitor campus addresses.
Campus vulnerability scanners are allowed and there will be no firewall exceptions for devices that have issues with scanning
Since systems using the shared firewall service are not isolated from each other, malicious insiders may still be able to access the systems on the protected side of the firewall.
This service can only accommodate entire subnets. If you only want a subset of your systems to use it, those systems must be put on a new network.
No. Customizations are not made for individual departments. However, it is an evolving service and changes will be made if necessary to support the general needs of campus workstation computing.
