TL;DR: High log volume and alert noise are driving escalating SIEM costs, and applying asset criticality plus threat context at ingestion and alerting time can suppress low-value signals while elevating activity tied to real adversary behaviour, according to Anomali’s whitepaper. That shifts detection quality from volume management to context-aware triage.

Questions worth separating out
Q: How should security teams reduce SIEM noise without losing important alerts?
A: Focus on context, not volume.
Q: Why do identity events need special handling in alert triage?
A: Identity events often look routine at volume, but the risk changes sharply when the same account, token, or session can reach critical systems.
Q: What breaks when suppression rules are too broad?
A: Broad suppression creates blind spots by removing low-noise events that may be the earliest indication of credential abuse, privilege escalation, or unusual access paths.
Practitioner guidance
- Define asset-criticality tiers for alerting Classify crown-jewel systems, admin planes, and sensitive data stores so ingestion and correlation rules can prioritise telemetry tied to those assets.
- Tune suppression around known attacker behaviours Build suppression logic from validated abuse patterns such as impossible access paths, privilege misuse, and suspicious token activity.
- Map identity telemetry to ownership and escalation paths Ensure service accounts, API keys, and privileged sessions are linked to accountable owners and response runbooks.
What's in the full article
Anomali's full whitepaper covers the operational detail this post intentionally leaves for the source:
- The specific ingestion-time logic used to apply asset criticality and threat context before alert creation.
- The operational model for suppressing low-value signals without losing high-priority detection coverage.
- The way threat intelligence is mapped to alert relevance and analyst workload reduction.
- The vendor's framing of how this approach affects SIEM operating costs and response focus.

Threat-informed telemetry is becoming a governance requirement, not just an efficiency tactic. SIEM programmes are no longer judged only on how much data they collect, but on whether they surface the right events fast enough to matter. When log volume rises faster than analyst capacity, context at ingestion becomes a control choice, not a tuning preference. Practitioners should treat relevance engineering as part of detection architecture.
A question worth separating out:
Q: Who should own false-positive suppression decisions in the SOC?
A: The SOC can operate the rules, but ownership should sit with the teams that understand the assets, identities, and business impact being protected. That usually means security operations, IAM, and application or platform owners share accountability. Suppression should be documented, reviewed, and tied to a clear escalation path when risk changes.
