Figure 13: Campus Compartmentalization Security Control Point(s)
The TMS zl Module, of course, doesn’t have to simultaneously fulfill all of its possible
roles. In Figure 13, above, a single TMS zl Module is acting as both traditional
perimeter security and is compartmentalizing a college campus network into the campus
administration portion, the business college portion, and the computer science college
portion where higher-risk activities such as virus and other malware research might be
conducted. In this scenario it is a prudent information security risk mitigation to add the
extra security controls of the firewall and IPS features between the higher-risk computer
science portion of the campus network and the lower-risk business activities in the
business college and campus administration portion of the campus network.
