Register or Claim Network Assets in NetReg: Subnets and individual IP addresses Offsite hostnames Subdomains CC IP Addresses

Initially, security contacts and their maintainers, as well as registered IP addresses and subnets, subdomains and off-site hostnames were converted from the previous Security Contact application.

For new registrations and ongoing maintenance of existing registrations:

Offsite Hosting in NetReg

Offsite hostname registration is available through NetReg.

In NetReg you can:

Request hostname(s) Identify Resource Proprietor, Data Protection Levels, etc. Provide DNS details for DNS Administrator, pending approval

Once the hostname is approved, NetReg will make a request to DNS Administrator on your behalf. Additionally, Offsite hostname de-registration requests to the DNS Administrator will send a request on your behalf to the DNS Administrator to remove the hostname’s DNS record....

What email address should I use for my security contact?

The email address should reach multiple people via a listserv, group address, or, ideally, a CalNet SPA account so that security incidents involving a department or group's IT Resources receive prompt attention. CalNet SPAs (Special Purpose Accounts) are CalNet IDs that can be shared by multiple users for collaborative purposes, and are recommended for this purpose.


Getting Started


NetReg uses distinct sets of security contacts (SCs) to support the various ways network resources are managed on campus.

Network assets (e.g., subnets, IP addresses, devices) are registered to SCs in NetReg to enable the correct routing of security notices. An SC is a role that is comprised of members. NetReg users who have membership in a security contact have varying levels of access privileges.

SC members may have the ability to:

View and respond to NetReg...

How are security notices routed?

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


What are Service Provider Security Contacts and how do they work?

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...
