Question 540
A security operations shift handoff reports this condition: A responder pastes full connector API credentials into an incident comment while documenting a failed automation run. Which condition best explains this security analytics result?
Explanation
Correct Answer
The underlying principle is: Incident notes can be visible to multiple analysts and are not a safe substitute for a managed secret store. Address this by: Remove exposed credential material from the case, rotate the affected secret and replace it with redacted diagnostic context. The confirming operational observation is: The incident contains useful error evidence without revealing the credential, and the old token no longer works.
Incorrect Answers
Configuring a handler's rules is insufficient until the handler is enabled for event generation. “Enable the handler, confirm its status, and replay a known qualifying log under authorized testing conditions” would remedy that alternative situation, but it would not correct the present issue: incident notes can be visible to multiple analysts and are not a safe substitute for a managed secret store.
“Preserve required source records and use the supported case status and targeted suppression workflow as appropriate” is the supported response when removing source evidence is not the same as recording a resolved incident outcome and may harm later audit or analysis. Here the decisive response is “Remove exposed credential material from the case, rotate the affected secret and replace it with redacted diagnostic context”, so that different intervention does not meet the stated requirement.
An indicator value alone does not establish that the affected host generated the behavior or belongs to the malicious infrastructure. “Link the relevant observed log field, time and source to the indicator record and case narrative” applies to that other condition. The reported evidence is a responder pastes full connector API credentials into an incident comment while documenting a failed automation run; this alternative would address the wrong dependency.
