Intrusion detection systems (IDS) are increasingly a key part of system defense, often operating under a high level of privilege to achieve their purposes. Therefore, the ability of an IDS to withstand attack is important in a production system.In this paper, we address the issue of survivable IDS. We begin by categorizing potential vulnerabilities in a generic IDS and classifying methods used to enhance IDS survivability. We then propose an efficient fault tolerance based Survivable IDS (SIDS) along with a systematic way to transform an original IDS architecture into this survivable architecture. Key components of SIDS include: a dual-functionality forward-ahead (DFFA) structure, backup communication paths, component recycling, system reconfiguration, and an anomaly detector. Use of the SIDS transformation should result in an improvement in IDS survivability at low cost.
