Network Security and Intrusion Detection
TL;DR
This work introduces persistent node evidence as an investigation-oriented representation boundary for provenance streams, and supports persistent node evidence as a bounded bridge from event prediction to precision-oriented offline investigation.
Controlled evidence-level and end-to-end comparisons show improved overall IoC recovery and attack-stage attribution over state-of-the-art provenance-based baselines over state-of-the-art provenance-based baselines in ANCHOR.

: Advanced Persistent Threats (APTs) are low-frequency, stealthy, and multi-stage attacks whose activities are embedded in massive volumes of benign host audit events, making both accurate detection and post-alert investigation challenging. Provenance graphs provide unified representations of interactions among process...

Results show that CSCProv achieves up to 30× provenance graph reduction while preserving attack-critical dependencies, and improves the efficiency of downstream attack detection, reducing detection time by 32.7–48.3% across different datasets and detection frameworks.

RECAL is presented, an unsupervised framework using relation-balanced masked graph learning to better capture rare interaction patterns and calibrates reconstruction errors against each relation's benign error distribution to produce comparable anomaly evidence, helping distinguish attacks from benign behavior and redu...

LLM agents rely on long-term memory to retain and reuse information when performing tasks over long horizons. Existing methods provide limited support for handling memories that become outdated as new observations or domain evidence arrive. Such outdated memories may remain semantically relevant, continue to affect dep...

Reproducing a provenance-based intrusion detector's score does not establish what that score says about its emitted alarms or the information its encoder uses. We audit nine released implementations, execute four detectors using their own code, and isolate three measurement effects. First, a fixed-alert comparison sepa...
