Detection AI

AI-Driven Solutions for Log Collection Issues in Detection Engineering

2025-08-11

If garbage goes in, silence comes out. AI can help with messy pipelines—but only when scoped to specific pain points and paired with measurement.

Where AI Helps—and Where It Doesn’t:#

  • Helps: schema discovery, tolerant parsing, entity extraction under mild drift.
  • Helps: predicting agent failure and backlog spikes from seasonality and leading signals.
  • Helps: classifying event value to route scarce ingestion budget wisely.
  • Does not help: inventing logs that never existed; seeing through intentional black holes.

Symptoms of Data Integrity Trouble:#

  • A single vendor minor release tanks parse success for a week.
  • Agents “healthy” according to infra, yet no events reach the SIEM.
  • FP bursts correlate with benign business cycles more than anything adversarial.

An AI‑Assisted Framework for Data Integrity:#

Layer 1 — Robust Parsing & Repair: - Learn field positions and synonyms with NLP; tolerate mild reorderings. - Infer truncated commandlines from context (parent/child processes, DLL loads). - Emit confidence scores; down‑rank low‑confidence extractions.

Layer 2 — Predictive Pipeline Health: - Forecast agent failure probabilities using host health, patch cadence, and historical gaps. - Predict backlog from traffic seasonality; auto scale brokers before the wave.

Layer 3 — Intelligent Routing & Tiering: - Score events by investigative value (identity, rare process, sensitive assets). - Route high‑value to hot storage; degrade gracefully for the rest.

Risks and Guardrails:#

  • Provenance: mark AI‑filled fields as inferred; never hide uncertainty.
  • Safety rails: ban automated “repairs” that could fabricate evidence.
  • Human review: sample and spot‑check corrections; compare to ground truth.

Measuring Effectiveness:#

  • Parse success ↑ with no spike in false extractions.
  • Coverage on replayed TTPs ↑ when underlying data wobbles.
  • On‑time rate ↑; backlog and darkouts ↓.

Case Sketch: CloudNative Inc. replaced brittle regex with NLP‑backed parsers, predicted collector brownouts from CPU and queue telemetry, and adopted value‑based routing. Parse success hit 99% and measured false negatives fell 40%.

Where tools can help: Many vendors claim “AI for logs.” Demand evidence and guardrails. VanatorX can supply replay and measurement alongside targeted AI, but the discipline matters more than the logo.
