    So, basically, you'd like to record all network traffic, since you will
    never know if an attack will take place during a given time period.

    At that point, it comes down to merely logging everything with a device
    that can keep up with your throughput requirements and have enough
    storage to retain whatever time slice you need. As David intimated, no
    IDS/IPS product will do this.

    I'm sure you could rig up a tcpdump solution with regular log rotations.
      If you're not concerned with data content, and just want to watch
    traffic patterns, the US Navy's Shadow[1] is worth looking into.

    You might also want to peruse the Honeynet Project[2]; if you deploy a
    device that sees no legitimate traffic, then deciding what to log
    becomes a lot easier, as nearly all traffic flowing to/from the honeypot
    device is suspicious.
