BLOCKCHAIN FOR USE IN COLLABORATIVE INTRUSION DETECTION SYSTEMS
Vikram Kanth · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 2019
As the threat of cyber attack grows ever larger, new approaches to security are required. While there are several different types of intrusion detection systems (IDS), collaborative IDS (CIDS) offers particular promise in identifying distributed, coordinated attacks that might otherwise elude detection. Even for this type of IDS, there are unresolved issues associated with trusting participants and aggregating data. Blockchain technology appears capable of addressing those issues. This thesis is focused on presenting a proof-of-concept experiment leveraging an Ethereum-based private blockchain for a CIDS that uses pluggable authentication modules (PAM) to track login activity toward detection of doorknob rattling attacks.
