Anyone else read the Gartner Guardian Agents report? The attribution gap they describe is exactly what broke our SIEM last month.
Got an alert last month on API call volume that looked off. Took us a while to trace it back because the SIEM logged the user identity, not the agent actually making the calls. The agent was running under an authorized user account, doing what it was supposed to do, but the logging had no way to distinguish agent-initiated actions from human-initiated ones.
We closed it as a false positive. Might have been wrong to do that. We don't know.
Everyone talks about the external stuff, prompt injection, agent compromise. That's not what I'm describing. The problem isn't someone attacking the agent. It's that the whole logging model assumes a human is behind every session. When an agent acts under a user's identity, your logs say the user did it. Your SIEM correlation rules were written assuming humans generate events at human speed. An agent running under the same identity quietly breaks every baseline you have.
We're running Splunk with a pretty mature detection ruleset. None of it was written with agents in mind. Agents invalidate that assumption. Nobody notices until something weird surfaces and you can't tell who or what caused it.
Came across the Gartner Guardian Agents report while trying to find a framework for this. The part about agents acting outside what any identity system can see is exactly what we keep running into.
What are people doing for agent attribution and behavioral monitoring, if anything?
