The following are suggestions from the ICN Network Operations Center
to help protect your network.
- To prevent system downtime, a security plan, which includes patched
operating systems, firewalls, up-to-date antivirus software packages,
and a little common sense is essential.
- The key to maximizing network integrity is to include a firewall in
the network design. Both hardware and software firewalls are readily
available and allows system administrators the granularity to specify
which systems or applications are available to external networks. This
is the foundation for a secure environment.
- Operating system vulnerabilities are frequently identified and updates
are regularly available and can easily be downloaded and installed.
Incorporating utilities, like Microsoft Auto-Update, is an easy way
to keep operating systems current. Keeping the operating system patched
is important because it protects from potential damage from computer
- With the widespread impact of viruses and worms, a good antivirus
software package is vital. As new worms/viruses surface, virus definitions
are posted and need to be applied to the antivirus software. Similar
to operating system updates, automated update utilities can be configured
to keep your antivirus software and definitions current.
- The last component in a security plan is common sense. Make certain
that the preview pane within an e-mail viewer package is disabled. It's
always a good practice to simply delete e-mail from unknown sources.
Furthermore, be selective with what attachments you open. A little forethought
can provide a lot of system protection.
