TSC-CC8.1 Guidance

The tsc-cc8.1 guidance requirement sits in the SOC 2 Common Criteria and drives how auditors evaluate whether you control changes that could impact security, availability, processing integrity, confidentiality, or privacy. Practically, it’s your “show me the change story” criterion. If you cannot demonstrate that changes were requested, risk-reviewed, tested, approved, and deployed under control, you will struggle to support a clean SOC 2 opinion even if your technical security posture is strong.

This requirement applies to more than software releases. Auditors will sample changes across the full stack: application code, infrastructure-as-code, cloud security groups, IAM policies, database schema updates, CI/CD pipeline changes, and production configuration changes. They will also ask how you handle emergency changes and whether your process prevents silent, unreviewed modifications.

This page gives requirement-level implementation guidance you can execute quickly: what the criterion means in plain English, exactly what to build, what evidence to retain, common audit hangups, and a practical 30/60/90-day plan to close gaps.

Regulatory text

Excerpt (TSC-CC8.1): “The entity authorizes, designs, develops or acquires, configures, documents, tests, approves changes.” ¹

What an operator must do

You must be able to demonstrate, for systems in SOC 2 scope, that:

1. Changes are initiated and authorized (someone asked for the change and an appropriate person accepted the request).
2. Changes are built or acquired and configured in a controlled way (code changes, third-party software updates, and configuration changes follow defined steps).
3. Changes are documented enough to support safe operation and troubleshooting.
4. Changes are tested prior to production impact (testing depth matches risk).
5. Changes are approved prior to implementation (and approvals are captured, not informal).
6. Evidence exists showing the process ran as designed for a representative set of changes (auditability is part of the control).

Plain-English interpretation (what CC8.1 is “really” asking)

CC8.1 asks one question: Can you prove you prevent unauthorized or unsafe changes from reaching production?

Auditors typically map this to core change-management outcomes:

• You know what changed, when, and why.
• You can identify who approved it and who implemented it.
• You can show testing happened and was appropriate for the change.
• You can show controls work even under time pressure (emergency changes).
• You can show the process covers all relevant change vectors, not just code.

If you only have a policy, you will fail on evidence. If you only have tool logs, you may fail on governance and consistency. You need both.

Who it applies to (entity + operational context)

Applies to: organizations undergoing a SOC 2 audit with systems in scope for the Trust Services Criteria ¹.

Operationally, it applies to:

• Engineering (application code, services, libraries)
• Infrastructure/Cloud (network rules, IAM, Kubernetes, Terraform/CloudFormation)
• IT operations (endpoints, MDM profiles, corporate SSO changes if in scope)
• Security (security tooling configuration, detection rules, key management configs)
• Data/DBA (schema changes, permission changes, data pipeline logic)
• Third parties (managed service providers making changes on your behalf)

Change types auditors often sample (plan coverage accordingly):

• Standard changes (planned releases)
• Normal changes (non-routine but planned)
• Emergency changes (hotfixes, incident response changes)
• Configuration changes (especially security-relevant settings)
• Patches and upgrades (OS, containers, dependencies, SaaS config updates)

What you actually need to do (step-by-step)

Step 1: Define scope boundaries and “what counts as a change”

Create a change scope statement aligned to your SOC 2 system description:

• In-scope environments (production, staging if used for approvals)
• In-scope systems (apps, cloud accounts, CI/CD, IAM)
• In-scope change categories (code, infra, config, third-party managed)

Deliverable: a one-page “Change Management Scope” addendum tied to your SOC 2 scope.

Step 2: Publish a change management procedure that matches reality

Write a procedure that is specific enough to execute:

• Intake method (ticket, PR, or both)
• Required metadata (reason, risk, systems impacted, rollback plan)
• Approval roles (product owner, engineering lead, security for high-risk)
• Testing expectations by change risk
• Implementation steps and post-change validation
• Emergency change flow (with after-the-fact review requirement)

Keep it short. Auditors punish fantasy workflows.

Step 3: Implement a single workflow across tools (ticket + PR + deploy)

A workable pattern:

• Every production change has a ticket (Jira/ServiceNow/Linear) with risk + approver.
• Every code/infra change is a PR/MR linked to the ticket.
• Every deployment references the PR via CI/CD metadata.
• Approvals happen in-system (ticket approval + PR approval), not in chat.

If your org moves fast, enforce “no ticket, no deploy” for production-impacting changes through CI/CD checks or release gates.

Step 4: Add risk-based controls (don’t over-control low-risk changes)

Define a lightweight change risk rubric:

• Low risk: copy change, non-prod config, internal-only feature flag default off
• Medium risk: standard release with automated tests
• High risk: IAM/network changes, crypto/key handling changes, database migrations

Then map required approvals/testing:

• High-risk changes require security review and explicit rollback planning.
• Medium-risk changes require peer review + test results.
• Low-risk changes still require traceability and approval, but fewer steps.

Step 5: Make emergency change handling auditable

Emergency changes are where CC8.1 often fails. Your emergency flow should include:

• Minimal pre-approval (on-call lead) to restore service or reduce security risk
• Documentation of why it was emergency
• Testing performed (even if limited)
• Post-implementation review with corrective actions if process was bypassed

Auditors will accept a different workflow for emergencies if you can show governance and post-review discipline.

Step 6: Build monitoring and periodic review

Implement a monthly or quarterly review (choose a cadence you can sustain):

• Sample changes and verify required fields, approvals, and test artifacts exist
• Identify bypasses (direct-to-main, console changes, manual hotfixes)
• Track remediation to closure

This aligns to the practical expectation that you “establish monitoring and review process” and “conduct periodic assessments” supporting CC8.1 ¹.

Step 7: Prepare an auditor-ready evidence package (reduce scramble)

Create an “audit binder” folder with:

• Policy/procedure
• Change risk rubric
• Emergency change procedure
• Change samples with end-to-end traceability
• Review meeting notes and findings

If you use Daydream to manage control narratives and evidence requests, map CC8.1 to a repeatable evidence checklist so each audit period becomes a refresh, not a rebuild.

Required evidence and artifacts to retain

Auditors typically want proof in three buckets: governance, operation, and effectiveness.

Governance (design)

• Change management policy/procedure (current, approved, versioned)
• Change scope statement for SOC 2 in-scope systems
• Change risk classification rubric and approval matrix
• Access/role definitions for approvers and implementers (supports segregation)

Operating evidence (run)

For each sampled change (code/infra/config), retain:

• Change ticket with description, systems impacted, risk rating
• Approval record (who/when) for ticket and/or change request
• PR/MR link with reviewer approvals and change diff
• Test evidence (CI results, QA signoff, test plan for high-risk)
• Deployment record (CI/CD logs, release record, change calendar entry)
• Post-deploy validation/monitoring notes
• Rollback plan (high-risk) and whether rollback was needed

Effectiveness evidence (oversight)

• Periodic change reviews (meeting notes, sampled items, exceptions)
• Metrics or exception logs (failed approvals, bypass attempts) if available
• Corrective actions and closure evidence for identified gaps

Common exam/audit questions and hangups

Questions you should be ready for

• “Show me the change process, then show me three examples end-to-end.”
• “How do you ensure production changes cannot bypass approvals?”
• “How do you classify change risk, and who decides?”
• “How are emergency changes handled and reviewed after the fact?”
• “How do you cover configuration changes made in cloud consoles?”
• “Who can approve and who can deploy? Can the same person do both?”

Hangups that trigger findings

• No population completeness: you show PRs, but not config/IAM changes.
• Approvals in chat: no durable audit trail.
• Testing is implied: no evidence beyond “tests passed” with no logs.
• Emergency change abuse: normal work routed through emergency path.
• Weak linkage: ticket exists, PR exists, deploy exists, but no traceability between them.

Frequent implementation mistakes (and how to avoid them)

1. Policy-only compliance

   • Fix: Pair policy with a tooling-enforced workflow and sampled evidence.

2. Ignoring third-party changes

   • Fix: Require third parties to use your change ticketing process or provide equivalent evidence and approvals for in-scope systems.

3. No control for “silent” configuration changes

   • Fix: Treat security-relevant configuration as code where possible; otherwise, require tickets and capture console audit logs as evidence.

4. One-size-fits-all approvals

   • Fix: Use risk-based approvals. Auditors want thoughtfulness and consistency, not maximum friction.

5. No periodic review

   • Fix: Run a repeatable review and retain the output. CC8.1 expects you to document control activities and maintain evidence of operation ¹.

Risk implications (why CC8.1 failures matter)

Poor change control is a direct path to:

• Security control regression (a firewall rule opened, MFA disabled, logging reduced)
• Availability incidents (untested releases, brittle infrastructure changes)
• Data integrity issues (schema changes without rollback plans)
• Audit scope credibility problems (auditors treat change management as foundational)

SOC 2 is an audit framework, not an enforcement regime, but CC8.1 gaps commonly surface as control exceptions that can affect your report outcome and customer trust ¹.

Practical 30/60/90-day execution plan

Days 1–30: Establish the minimum viable CC8.1 system

• Confirm in-scope systems and write the “what counts as a change” statement.
• Publish change procedure + emergency change procedure.
• Standardize required fields in tickets (risk, impacted systems, approver, rollback).
• Enforce PR reviews for repos in scope; require linking ticket IDs in PR titles.
• Start retaining deployment logs and CI test output for releases.

Deliverable: one end-to-end change sample package you can hand to an auditor.

Days 31–60: Close bypass paths and add oversight

• Implement CI/CD gates for production deployments (approval required, ticket link required).
• Address config-change coverage: infrastructure-as-code backlog, or console change logging + ticket requirement.
• Define the approval matrix and ensure role assignments match it (segregation).
• Start periodic change review meetings; log exceptions and fixes.

Deliverable: change population list and evidence that bypasses are detected and corrected.

Days 61–90: Prove consistency and readiness for sampling

• Build a sampling binder with multiple changes across categories (code, infra, IAM/config, emergency).
• Run an internal “mock audit” walkthrough with engineering and ops.
• Fix recurring exceptions (missing rollback plans, incomplete test artifacts, weak linkage).
• Operationalize evidence collection in Daydream (or your GRC system) so evidence accrues continuously.

Deliverable: auditor-ready binder + a sustainable evidence pipeline for the audit period.

Frequently Asked Questions

Does CC8.1 require a formal CAB (Change Advisory Board)?

No. CC8.1 requires authorization, testing, approval, and evidence, but you can meet it with lightweight approvals in tickets and PRs as long as roles, risk, and traceability are clear ¹.

Are configuration changes (cloud console clicks) in scope?

If the configuration affects an in-scope system, treat it as an in-scope change. Either manage it as code or require a ticket plus retention of cloud audit logs showing what changed and who changed it ¹.

What’s the minimum testing evidence auditors accept?

Testing needs to be appropriate to change risk, but it must be evidenced. For most teams, that means CI test results for code changes and a documented validation/rollback plan for high-risk infrastructure or IAM changes ¹.

How do we handle emergency changes without failing the audit?

Define an emergency path with limited pre-approval, then require prompt documentation and a post-change review that records why the bypass happened and what you changed to prevent recurrence ¹.

Can the same engineer approve and deploy a change?

Auditors often scrutinize this. If your org can’t fully separate duties, use compensating controls such as required peer review approvals, protected branches, and restricted production deploy permissions with monitoring and periodic review ¹.

What evidence should we prepare for third parties that deploy into our environment?

You need traceability and approvals for their changes too. Require them to open your change tickets or provide equivalent artifacts (change request, approvals, test evidence, and deployment record) mapped to your in-scope systems ¹.
