Bro, SNORT, SGUIL, Tcpdump, and Wireshark are some nice tools.

By itself, a single install of Snort/Bro is not necessarily a complete
IDS,  as it cannot inspect the contents of outgoing SSL sessions,  so
there can still be Javascript/attacks against the browser, or SQL
injection attempts encapsulated in the encrypted tunnels;    I am not
aware of an open source tool to help you with SSH/SSL interception/SSL
decryption for implementation of  network-based IDS.

You also need a hand-crafted rule for each threat  that you want Snort
to identify...
Most likely this entails making decisions about what commercial
ruleset(s) you want to use and then buying the appropriate
subscriptions.
