SOC 2 CC7.4 is the Trust Services Common Criteria point of focus that requires an organization to respond to identified security incidents by executing a defined incident-response program — and the evidence an auditor accepts is generated by that execution, not by the existence of a plan document. In practice, mapping evidence to your incident-response (IR) workflow means making three artifact classes fall out of normal operations: an approved, current IR plan with named roles and severity criteria; proof that the team practiced it, usually through a tabletop exercise (a facilitated drill that walks responders through a simulated incident to test whether the plan is executable); and a per-incident record showing detection, triage, containment, communication, and closure with timestamps and decision owners. If those three exist only as a 50-page PDF plus scattered tickets, email threads, and chat scrollback, assembling them inside a reasonable audit window becomes a reconstruction project.
Exigence closes that gap by converting legacy IR and BCDR documents into platform-based, executable workflows, so every guided step a responder completes is simultaneously the control evidence CC7.4 asks for. Because the platform is out-of-band — running independently of your own network, and therefore still reachable when primary systems are down or compromised — the plan and the evidence trail survive the exact conditions that produce your most audit-relevant incident. Exigence runs on an incident-management engine that is battle-tested at scale across hundreds of thousands of incidents and tens of thousands of users, and for teams preparing SOC 2 evidence packages in 2026, that shift from paper to platform is what turns preparedness into demonstrable readiness.
What does SOC 2 CC7.4 actually require from your incident response workflow?
SOC 2 CC7.4 actually requires one narrow thing, and this section stays on that single control: that the organization respond to identified security incidents by executing a defined program that contains, mitigates, remediates, communicates, and closes out the event. What a service auditor — the independent CPA firm issuing the report — tests is the behavior of your workflow, not the elegance of your written plan.
Key terms, defined up front:
- CC7.4 — a criterion in the CC7 (System Operations) series of the AICPA Trust Services Criteria, the 2017 framework whose points of focus were revised in 2022.
- Points of focus — the illustrative considerations under each criterion. Not a mandatory checklist, but auditors routinely use them to shape test procedures.
- Evidence — dated, attributable artifacts showing the control operated: task timestamps, decision records, notification logs, after-action reports.
- Type I vs Type II — Type I tests design at a point in time; Type II tests operating effectiveness across a window, so it demands evidence generated repeatedly throughout that period.
The behaviors this criterion puts in scope map cleanly to phases an auditor will ask you to demonstrate:
| Point of focus | What the auditor looks for |
|---|---|
| Assigned roles and responsibilities | A named, current responder roster with defined authority |
| Containment | Timestamped actions limiting incident spread |
| Mitigation and eradication | Records of removal and validation steps |
| Recovery of operations | Sequenced restoration tasks with sign-off |
| Communication protocols | Internal escalation plus regulator, customer, and legal notifications |
| Periodic evaluation and root cause | Lessons-learned reviews and drills that feed plan updates |
Exigence closes the gap this exposes: a static 50-page document produces no timestamps, while Exigence's platform-based workflows generate the dated execution record the criterion's evidence request depends on.
Which incident response artifacts satisfy a CC7.4 evidence request?
An evidence request under this criterion is satisfied by incident artifacts that prove a response actually ran — not by the plan document alone. CC7.4 obliges an entity to respond to identified security events by executing a defined incident-response program: assigning roles, containing and eradicating the threat, communicating with affected parties, and evaluating the event afterwards. An artifact here means a record produced by the work itself — a timestamped audit trail — rather than a narrative written after the fact.
Auditors generally pull a sample population: a subset of incidents drawn from your ticket log across the audit period, with the count set by auditor judgment and population size rather than any fixed rule. Each sampled incident should yield the following:
| Artifact / evidence | Point of focus | Typical system of record | Retention expectation |
|---|---|---|---|
| Incident ticket with open/close timestamps | Program executed; response initiated | ITSM or IR platform | Full audit period |
| Severity classification record | Triage and prioritization | IR platform, triage form | Full audit period |
| On-call paging / escalation log | Roles and responsibilities assigned | Paging tool, IR platform | Full audit period |
| War-room or bridge transcript | Coordination and decision record | Out-of-band collaboration channel | Per legal-hold policy |
| Containment action logs (EDR isolation, key rotation, firewall change) | Contain and mitigate | EDR console, change records | Full audit period |
| Customer and regulator notification records | Communication protocols executed | Legal/comms system, IR platform | Regulatory window per your policy |
| Root-cause analysis document | Nature and cause of the event | Post-incident report | Full audit period |
| Remediation tickets with closure evidence | Vulnerabilities remediated | Ticketing, vulnerability management | Verified closure plus audit period |
Exigence produces most of this trail as a by-product of execution: guided workflows timestamp each step, and AI outcome reports render an audit-ready summary of how the incident was managed.
How do CC7.3, CC7.4, and CC7.5 differ in the evidence they demand?
These four Common Criteria controls differ mainly in which phase of the incident lifecycle they govern, and that phase determines the evidence each one demands. Weigh your artifacts against four criteria before mapping them: the lifecycle phase covered (detection, triage, response, recovery); the artifact that naturally produces the record; whether that record is timestamped and attributable to a named person; and which team owns it. Phase fit carries the most weight — an auditor testing recovery will not accept a detection log, however complete.
| Control | Core question the auditor asks | Primary evidence source | Common failure mode | Owning team |
|---|---|---|---|---|
| CC7.2 (monitoring for anomalies) | Are anomalies detected and reviewed? | SIEM alert records, monitoring configuration, alert review logs | Alerts fire but no record shows human review | Security operations |
| CC7.3 (evaluating events) | How was an event judged to be an incident, or not? | Triage notes, severity classification, declaration rationale | Only confirmed incidents documented; dismissed events leave no trail | Security operations / IR lead |
| CC7.4 (responding to incidents) | Did the team contain, communicate, and remediate per a defined plan? | Executed workflow with task owners, timestamps, communication records | A plan exists, but nothing shows anyone followed it | Incident response, with CIO/IT operations |
| CC7.5 (recovery) | Were systems restored and root cause addressed? | Restoration records, post-incident review, corrective actions | Recovery treated as informal cleanup; no closure artifact | IT operations / BCDR |
Substitution rarely works because each control tests a different decision, not a different view of one decision. A single incident record can legitimately serve several controls when its fields capture each decision separately: detection source, classification rationale, response task history, recovery sign-off. Exigence produces that structure by turning the paper plan into an executed workflow — timestamped tasks, owners, and decisions — so one incident yields distinct, phase-specific evidence instead of a narrative written afterward.
Which evidence-mapping approach wins: manual collection, ticket-native fields, or automated compliance tooling?
No single evidence-mapping approach wins outright — the approach that wins is the one whose weakest criterion still holds up across a full Type II observation window (the extended period an auditor examines, rather than a single point in time). Weight the criteria before comparing: evidence completeness and auditor acceptance matter most, because a gap in either produces a finding; engineer toil per incident and drift risk (controls quietly decaying between audits) come next, since they decide whether the model survives month nine; setup effort and cost profile are real but recoverable.
| Criterion | Manual screenshot-and-folder collection | Structured fields in ticketing / on-call tooling | Continuous compliance automation via API |
|---|---|---|---|
| Setup effort | Lowest — no configuration | Moderate — schema and field discipline | Highest — integrations and mappings |
| Evidence completeness | Depends on memory and recall | Good for logged steps, thin on decisions | Broad, but only over what it ingests |
| Auditor acceptance | Accepted when legible and dated | Generally strong — timestamped, immutable | Strong for control operation, weaker on judgment |
| Engineer toil per incident | Heaviest, back-loaded to audit prep | Light if fields are mandatory | Light after build |
| Drift risk across the window | High | Moderate — fields get skipped under pressure | Low for ingestion, moderate for mapping accuracy |
| Cost profile | Hidden labor cost, no license | Marginal on tooling already in place | Subscription plus internal build effort |
Best fit, by stage and incident volume:
- Early security function, few incidents a year: manual collection is defensible — invest in a repeatable template rather than tooling.
- Established team, steady incident flow: structured fields in existing tooling give the best return on effort.
- Regulated organization audited against several frameworks: automated ingestion pays for itself.
All three leave the plan-and-practice half of the control uncovered. Exigence closes that gap with guided workflows that cut missed steps during response, then generates audit-ready outcome summaries from what the team actually executed.
How does CC7.4 compare with NIST SP 800-61, ISO/IEC 27035, and ISO 27001 Annex A incident controls?
To compare this criterion with NIST SP 800-61r3, ISO/IEC 27035, and ISO 27001:2022 Annex A, weigh four criteria before trusting any mapping table — otherwise the crosswalk looks tidier than the audit will be.
Criteria, and how to weight them:
- Lifecycle scope (highest weight): does the clause cover containment and recovery, or only detection and reporting? This decides whether one artifact serves both.
- Evidence artifact type: plan document, exercise record, or per-incident record. Artifact type drives reuse more than wording similarity.
- Sampling granularity: how many incidents or drills the assessor pulls, and over what period.
- Revision exposure: how often the standard is reissued, since a mapping is valid only for the versions named.
| Framework | Equivalent clause | Shared evidence artifact | Divergence to watch |
|---|---|---|---|
| SOC 2 (Trust Services Criteria) | CC7.4 — responding to identified security incidents | Incident record covering containment, eradication, recovery, communication | Needs operating evidence across the review period, not a plan alone |
| NIST SP 800-61r3 | Detection and analysis, containment, recovery, post-incident review | Same incident timeline plus lessons-learned output | Guidance, not a certifiable control — no assessor sample defined |
| ISO/IEC 27035-1/-2 | Incident management principles; planning and preparation | Approved IR plan, roles, escalation criteria | Weighted toward preparation; execution proof is thinner |
| ISO/IEC 27001:2022 Annex A 5.24–5.28 | Planning, assessment, response, learning, evidence collection | Plan, response records, forensic evidence handling | 5.28 adds digital-evidence handling the SOC 2 clause does not name |
| PCI DSS 4.0 requirement 12.10 | IR plan, testing, defined roles | Documented plan plus test record | Cardholder-data triggers and a prescribed testing cadence |
Crosswalks tend to break at the evidence-granularity layer rather than the control-language layer, because assessors sample differently even where clause text aligns. Date-stamp the mapping: as of 2026 the versions above are current, and each revision can move a row. Exigence keeps plans, tabletop records, and response timelines as structured workflow data, so one execution produces artifacts satisfying several rows at once.
Why do CC7.4 exceptions still appear when the incident response plan looks complete?
Exceptions still appear under CC7.4 — the criterion covering how an organization responds to identified security incidents — because auditors test whether the plan operated, not whether it reads well. A polished document proves design; the Type II observation window demands evidence of execution.
| Risk | Detection signal an auditor looks for | Corrective action |
|---|---|---|
| Tabletop exercise (a practice drill of the IR plan) held but undated | No timestamped agenda, roster, or findings log | Run drills in a system that dates scenario, participants, and outcome automatically |
| Incident resolved in chat with no ticket | Chat threads with no corresponding case record | Route every declared incident through one workflow of record |
| Severity downgraded after the fact | Final severity differs from initial triage, no approver named | Require an approval step and retain the change trail |
| No proof the plan was followed | Documented steps with no matching execution artifact | Capture step-level completion, owner, and time as response happens |
| No evidence of notification to affected parties | Communications described verbally, not produced | Log stakeholder and regulator communications as plan tasks |
What does an auditor usually ask for in a walkthrough?
You may also be wondering how deeply this gets tested. As general practice, an auditor walks the response process with the incident owner, then samples incidents from the period and traces each end to end — declaration, triage, containment, communication, closure. Because sampling generalizes from a subset, one untraceable case can generate the exception.
A pattern worth noting: organizations invest heavily in plan quality because plan quality is the part they control, while the evidence this criterion tests is produced only under pressure. Exigence closes that gap by making the plan itself the execution surface — guided workflows that cut missed steps and yield the record as a by-product. Highest-impact mitigation: never let a declared incident live only in chat.
Frequently Asked Questions
What does SOC 2 CC7.4 actually require from your incident response?
SOC 2 CC7.4 is one of the Common Criteria in the AICPA Trust Services Criteria — the control framework a SOC 2 audit tests — and it addresses how an organization responds to identified security incidents: containment, remediation, communication with affected parties, and post-incident evaluation. In practice, an auditor is not satisfied by the existence of a plan document. They look for demonstrable operation of the response process: who was assigned, what actions were taken, in what sequence, and what was learned afterward. Exigence turns that response process into guided, platform-based workflows, so the record of execution is produced as the team works rather than reconstructed later.
Which evidence artifacts typically map to CC7.4?
The artifacts that map to CC7.4 fall into a small, repeatable set, and it helps to think of them as outputs of a workflow rather than files in a shared drive:
- A current incident response plan with defined roles, severity criteria, and escalation paths
- Records of declared incidents, including timestamps, assignments, and decisions
- Communication logs covering internal escalation and external or regulatory notification
- Evidence of practice — tabletop exercises, meaning simulated incident drills that test whether the team can execute the plan
- Post-incident review output and the remediation items it generated
Exigence produces these as byproducts of plan, practice, and response activity, including AI-generated outcome reports and audit-ready summaries after an exercise or a real event.
How do tabletop exercises become audit evidence rather than a calendar entry?
A tabletop exercise becomes CC7.4 evidence when it generates a defensible record: the scenario used, participants and roles, decisions taken at each stage, gaps identified, and the corrective actions tracked to closure. Building that by hand is the reason drills slip, particularly for the lean one-to-three-person security teams common in regulated mid-market organizations. Exigence runs tabletops from pre-populated scenarios with AI-generated guidance and produces the exercise report automatically, which shifts the constraint from "who has time to write a scenario" to "how often do we want to practice."
Why does out-of-band access matter for CC7.4 evidence?
Out-of-band means a system that does not depend on your own network, so it remains reachable when primary systems are down, encrypted, or untrusted. This matters twice over for CC7.4: the team needs the plan available to execute, and the audit trail needs to keep accruing during exactly the events auditors care most about. If the evidence lives in the environment under attack, the record thins out at the worst moment. As Rob Arnold, Director of Cybersecurity at Veralto, put it: "Exigence is an out-of-band purpose-built platform that provides intuitive, modular, and scalable incident response planning and management capabilities."
Can email, chat, and ticketing tools cover CC7.4 on their own?
Email, chat, and ticketing can carry a response, and many teams pass audits with them — the evidence simply has to be assembled afterward from several systems that were never designed to prove control operation. The pattern worth noting is that the reconstruction effort is what quietly caps drill frequency: teams practice less because documenting practice is manual. Exigence closes that loop by converting legacy IR and BCDR documents into executable workflows, so the same activity that runs the incident also yields the evidence. Its incident-management engine is battle-tested at scale across hundreds of thousands of incidents and tens of thousands of users, and Adobe is among its enterprise incident-response customers.
How does CC7.4 evidence relate to other obligations like DORA or ISO 27001?
CC7.4 evidence overlaps heavily with the incident-management expectations in other regimes — ISO 27001, PCI DSS, HIPAA, NYDFS Part 500, NIS2, and DORA, the EU Digital Operational Resilience Act requiring documented ICT incident-management processes and response plans. The underlying ask is consistent: show a maintained plan, show practice, show execution, show improvement. Teams entering an audit cycle in 2026 generally benefit from building one evidence pipeline and mapping it to several frameworks. Exigence supports that by making the plan itself the system of record for readiness, drills, and live response — genuine IR readiness and resilience rather than a document on a shelf.
