| Summary

| This module expanded upon the idea that network security is a constant cycle of securing, monitoring, testing, and improving, centered on a security policy. This module discussed a number of methods that administrators can use to secure a network. The initialization and configuration of a Firewall IDS router was discussed and the student gained hands-on experience by configuring an IDS router through lab activities.

The student then learned that monitoring the network is done through logging and syslog. Sample logs were shown and the typical attacks that administrators must counter were discussed. Students were then shown a syslog server and given the opportunity to see how it works.

Next, the student learned about the SNMP. The student learned how SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. The student learned how SNMP, although simplistic, can be used effectively to assist the administrator in monitoring the network through its information gathering capabilities.

Finally, the student learned about router management through the use of the Security Device Manager and VMS.
