What's your favorite network-based security tool?

tcpdump

how about DenyHosts and sshblack? I use both of them.

firewalld.....?

another request for denyhosts here

The most recent denyhosts release appears to have been in 2008.

yes, it is one of those bits of software that "just works". no need for any changes. It gets installed on every server I set up, and keeps the brute force ssh attacks at bay.

iptables :]

Indeed :)

Wireshark

Firestarter is quite old for a security app: last release was 2005. Is it judicious to include it in the list?
