10.4 — Audit logs are reviewed, using automated mechanisms

Requirement

Security events and logs of critical components and those that store, process or transmit cardholder data are reviewed at least once daily, using automated mechanisms such as a SIEM, and exceptions and anomalies are identified and addressed.

What the engine looks for

Every group below must be satisfied — by an affirmative statement, not a plan, a hedge or a denial — for the control to count as covered. A term ending in … matches any word it begins. Supporting terms do not change the verdict — they raise confidence and distinguish a policy that names a mechanism from one that gestures at a category.

Finding any of these outranks coverage — a policy that admits the gap is worse than silence.
