Fwanalog is a firewall log parsing and summarizing shell script.
One of the best things about fwanalog is that it's highly extensible. With just a few simple edits, you can easily adapt this tool to work with other logfile formats if needed. In terms of its output, fwanalog relies on the powerful log analysis program Analog to create its reports. By converting firewall logs into a fake web server log and calling Analog with a modified configuration, fwanalog is able to produce detailed and informative reports.
The installation process for fwanalog is relatively straightforward. You simply need to decompress the distribution file, update the configuration file as needed, and then execute the shell script. Once the script has run, you should be able to access HTML and text reports that have been generated based on the firewall logs.
Recent updates to fwanalog include bug fixes for the Cisco function, as well as added support for Sonicwall firewalls. Additionally, there's now a lock file to avoid multiple output directories in case of simultaneous calls. If you need a software tool that can help you parse and summarize firewall logs, fwanalog is definitely something to consider.
