Provenance-based intrusion detection systems (PIDS) are widely seen as a critical line of defense against advanced persistent threats (APTs), according to a new arXiv preprint. The abstract describes these systems as essential, but notes that their practical use is severely hampered by alert flooding.
The paper, titled "Cutting the Fuse: Actionable APT Attack Blocking in Provenance-based IDS," appears to address this bottleneck directly. While the full abstract is truncated, the stated focus is on making attack blocking actionable rather than merely generating alerts.
Because the source is a preprint and the abstract is incomplete, the details of the proposed method are not yet available. The significance lies in the problem it targets: reducing alert noise so that PIDS can be deployed effectively against sophisticated, long-term threats.
