Just caught a concerning write-up from one of our community members over at SecIntelDaily. A major competitor's agent framework had a vulnerability that allowed agents to bypass its central event logging entirely. The flaw was in the configuration schema—a misplaced optional flag that, if set, would send logs to a local buffer but never forward them to the SIEM.

This is a stark reminder for our own deployments. When integrating agent events into your SIEM, the pipeline's integrity is everything.

I'd suggest a quick review of your own agent logging configs, especially if you've done any custom tuning. Look for:

* **Local buffering vs. forwarding:** Ensure any local cache or buffer is explicitly a *backup*, not a dead-end.
* **Permission models:** Can the agent process (or a subprocess) alter its own logging destination or verbosity? This is a common escalation path.
* **Health monitoring:** Your SIEM should have alert rules not just for malicious events, but for the *absence* of expected heartbeat or periodic events from your agent fleet.

The use case here is clear: we must threat-model our own observability stack. An agent that can hide its tracks is a double threat. Consider it an "Agent Tampering" technique in your STRIDE model for the overall system.

Has anyone here built specific detections for agent log suppression? I'm thinking along the lines of canary events or statistical drops in event volume per host.
