Abstract

As cyber-attacks become increasingly sophisticated and stealthy, accurately distinguishing between benign behavior and malicious intrusions has become both more critical and more challenging. Provenance-based intrusion detection systems (PIDS) show strong potential for detecting malicious activities through fine-grained causality analysis, which has gained significant attention from both industry and academia. Among the various PIDS approaches, rule-based systems are particularly favored for their low overhead, real-time detection capability, and interpretability. However, these systems face challenges in reducing false positive rates, primarily due to the lack of fine-tuned rules and specific environments. In this paper, we introduce CAPTAIN+, a rule-based PIDS that autonomously adapts to diverse environments online. Specifically, we propose three adaptive parameters to adjust the detection configuration for nodes, edges, and alarm generation thresholds. Initially, we build a differentiable tag propagation framework and utilize the gradient descent algorithm to optimize these adaptive parameters based on the training data. In this extended version, we integrate an online learning module into the detection stage to dynamically optimize adaptive parameters based on real-time feedback from the detection process. We evaluate CAPTAIN+ based on data from DARPA TC, OpTC datasets, and PKU ASAL datasets. The results demonstrate that CAPTAIN+ offers superior detection accuracy, lower…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CAPTAIN transformed traditional rules into a differentiable framework, utilizing gradient descent to adaptively optimize parameters on benign data, but it still carries the risk of false negatives for unknown attacks that do not deviate significantly from normal patterns.

    “CAPTAIN innovatively transformed traditional rules into a differentiable framework, utilizing gradient descent to adaptively optimize parameters on benign data, though it still carries the risk of false negatives for unknown attacks that do not deviate significantly from normal patterns[7].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
