Security events are evaluated to determine whether they could or have resulted in a failure to meet objectives (security incidents).
Also written as CC 7.3, TSC CC7.3, SOC2 CC7.3, SOC 2 Type 2 CC7.3.
Security event evaluation is one of 5 criteria in the System Operations (CC7) series of the Security (Common Criteria) category. Security events are evaluated to determine whether they could or have resulted in a failure to meet objectives (security incidents). CC7 covers detection and response, so the evidence is operational: monitoring configuration, alert samples, incident tickets with timestamps, and proof that identified issues were actually closed out.
When preparing for a SOC 2 audit against CC7.3, gather artefacts such as:
CC7.3 corresponds to the following ISO 27001:2022 Annex A control(s): A.5.24, A.5.25, A.6.8. If you already run an ISO 27001 ISMS, map your existing evidence for these controls to CC7.3 rather than duplicating work.
Yes. CC7.3 sits in the Common Criteria, which apply to every SOC 2 engagement regardless of which additional categories you scope in — there is no SOC 2 report that omits them.
In a Type 1 report the auditor assesses design only — does a control exist at a point in time that would meet CC7.3 if it operated. In a Type 2 report they also test operating effectiveness by sampling evidence from across the review period, typically 3 to 12 months. That difference is why Type 2 evidence has to be continuous rather than assembled the week before fieldwork.
A control that fails becomes an exception, which the auditor describes in the report along with management's response. Exceptions do not automatically make a report "failed" — a SOC 2 report is an opinion, not a pass/fail certificate — but a qualified opinion is what customers notice, so remediate and re-test before fieldwork closes where you can.
Yes — CC7.3 aligns with ISO 27001:2022 Annex A control(s) A.5.24, A.5.25, A.6.8. If you already run a certified ISMS, re-point that evidence rather than building a parallel set; the underlying control is the same and only the reporting format differs.
