pixlog is a utility for compiling useful reports from the syslog messages of a Cisco PIX firewall. As tens of megabytes of data can be generated by a PIX firewall per minute, pixlog cooperates with syslogd to parse the data as it comes in, generating nice looking HTML reports. Screenshot available here.

Many IDS systems detect buffer overflow exploitation by looking for a series of NOP's (hex 90) which are typically used to pad the buffer so the offset does not have to be exact. Instead of using NOP's, a stealthy exploit could jump to the next instruction (jmp 0x00) or jump a small number of instructions.
