Abstract
System management is an important part of configuring and maintaining a firewall. Network management, although appearing simple on the surface, can be quite complex. To effectively manage the Cisco PIX, one needs to be aware of PIX as well as networkwide issues. When configuring the PIX for logging, a choice from a variety of logging paths, such as buffered logging, console, Telnet/SSH sessions, syslog servers, or SNMP can be made. With each of the logging paths, message severity levels ranging from Level 1 (alert) to Level 7 (debug) based on the needs can be selected. Aside from selecting the severity level, one can choose from several facility levels to direct the flow of the syslog messaging. The default facility level is local4 (20), but other facility levels to redirect syslog messages from different sources to a syslog server destination of choice can be used. The Cisco PIX firewall can be managed using a console port, but most of the time the PIX is managed by remote access. The two popular choices of protocol for remote access are Telnet and SSH. An alternative method of accessing the PIX firewall remotely for system management is the Cisco PDM utility. PIX device manager (PDM) is a Java application that allows the management of the Cisco PIX using a Web browser.
