"*Abstract*

The Intrusion Detection System (IDS), introduced in IBM i5/OS, is a system
that notifies you of attempts to hack into, disrupt, or deny service to the
system. Prior to IDS, the i5/OS took some protective measures against the
types of intrusions described here. However, with the new IDS support, the
i5/OS system can now tell you about the intrusions.
This IBM Redpaper describes the following types of intrusions on the i5/OS
system that are caught, audited, and, in many cases, discarded—before they
become a threat:
Attacks
- IP fragments
- Malformed packets
- SYN floods
- Internet Control Message Protocol (ICMP) redirect messages
- Perpetual echo
- Restricted IP options
- Restricted IP protocols
Scans
Traffic regulation anomalies for TCP and UDP
