Inexpensive Cisco Network Log Analysis Print E-mail
User Rating:      How can I rate this item?
Source: - Posted by Benjamin D. Thomas   
Network Security This document is intended to explain why network logging and log analysis is important, and provide instructions for people who want to do this on their Cisco equipment (especially the PIX firewall) without spending a lot of money. Although you may not get all of the spiffy features that you will find in high-end offerings from companies like Cisco, NetIQ, Symantec and others, you can get a very good security bang for the buck with simple and inexpensive systems. Although this document is specifically intended for logging on a Cisco PIX, pretty much the same commands should work for other devices such as routers. You will see different screens, and Sawmill may detect them differently, but it is essentially the same process.

Please note: I have been informed that logging on other Cisco devices, notably routers, can be performed on a per-ACL basis, and tends to provide summary data, rather than detail. You should look into this if your results are not what you think they should be.
