Description:

o apache-monitor - monitors mod_status output and stores web
server activity in a RRD file

o apache-monitor-graph - creates pretty graphs from a RRD file
populated by the previous script (you can find an example here)

o apache-protect - monitors mod_status output to detect a DoS
attack, then uses the blacklist tool to cut the offending IP
address at the firewall

o blacklist - uses iptables to create a temporarily blacklist

o blacklist-webclient.c - a C program that can be marked suid
root, and called from a non-root script to blacklist IP
addresses

o error_log_ai - implementation of the Artificial Ignorance
concept (devised by Marcus J. Ranum) for the Apache error log

o httpd-guardian - stateful Denial of Service defence together
with ModSecurity 1.9. Uses blacklist to cut of the offending IP
addresses dynamically.

o mod_globalerror.c - Apache 2 module that allows the server to
have per-virtual host error logs and have one file where all
errors are duplicated (useful for server monitoring)

o logscan - easy-to-use log analysis script, supports field names
and regular expressions (will support anti-evasion techniques in
the future)
