12 Chapter 1:What is Red Hat Network?
The
Red Hat Network Daemon
(
rhnsd
) runs in the background as a service and probes the Red Hat
Network for notifications and updates at set time intervals (see Chapter 6, Red Hat Network Daemon
for further information).
1.1 Automatic Notifications
During registration, you can configure Red Hat Network to send you email notifications of new and
updated software packages. Automated notifications of the latest updates
• Reduce the time and effort required by system administrators to stay on top of the Red Hat errata
list
• Minimize security vulnerabilities in your network by providing the patches as soon as Red Hat
releases them
• Filter out package updates not relevant to your network
• Provide a reliable method of managing multiple systems with similar configurations
1.2 Security, Quality Assurance, and Red Hat
Network
Red Hat Network provides significant benefits to your network including security and quality assur-
ance. All transactions made between you and Red Hat Network are encrypted, and all RPM packages
are signed with Red Hat’s GNU Privacy Guard (GPG) signature to ensure authenticity.
Red Hat Network incorporates the following security measures:
1. Your System Profile available at http://www.redhat.com/network/ is only accessible with the
correct user name and password.
2. A Digital Certificate stored on the client system in the file
/etc/sysconfig/rhn/systemid
after registration is used to authenticate the system during each transaction between the client and
Red Hat Network.
3. All notifications and information messages are signed by Red Hat with an electronic signature us-
ing GPG. The rpm utility can be used to verify the authenticity of the package before it is installed.
4. All transactions are encrypted using a Secure Sockets Layer (SSL) connection.
5. All packages are tested and verified by the Red Hat Quality Assurance Team before they are added
to the Red Hat errata list and Red Hat Network.
