CPCSC Level 2 03.12.05: Information Exchange
Apply information exchange to assess controls, track remediation, monitor effectiveness, and manage information exchanges for CPCSC Level 2 readiness. This guide separates the official ITSP.10.171 control language from practical implementation, evidence, auditor questions, and related controls.
Formal Control Language
Official ITSP.10.171 wording for 03.12.05. Use the Cyber Centre publication and contract requirements as the source of truth for certification, assessment, or procurement submissions.
- Approve and manage the exchange of specified information between the system and other systems using [Selection (one or more): interconnection security agreements; information exchange security agreements; memoranda of understanding or agreement; information sharing arrangements; service level agreements; user agreements; nondisclosure agreements]
- Document, as part of the exchange agreements, interface characteristics, security and privacy requirements, and responsibilities for each system
- Review and update the exchange agreements [Assignment: organization-defined frequency]

What This Means In Plain English
Information Exchange is part of the CPCSC Level 2 Security assessment and monitoring family. This is about proving controls are assessed, gaps are tracked, monitoring continues between assessments, and information exchanges are governed.
For a founder, CISO, engineer, or compliance owner, the practical question is whether information exchange is visible in real operating evidence: a setting, workflow, ticket, log, approval, review, or exception record that can survive an external assessment.
Level 2 is different from Level 1 because the evidence has to survive an external assessment. A policy statement helps, but the stronger answer is a record that shows who did the work, when it ran, what system setting or workflow enforced it, and how exceptions were handled.
How To Implement It
1
Define the in-scope systems, owners, users, vendors, and data flows affected by information exchange.
2
Maintain an assessment plan, test controls, track POA&M items, monitor control health, and document exchange agreements for specified information.
3
Translate the formal requirement into one or two operating procedures: who performs it, how often, where it is recorded, and who approves exceptions.
4
Configure the relevant systems so the control is enforced by identity, endpoint, cloud, network, ticketing, monitoring, vendor, or documentation workflows rather than memory.
5
Keep evidence in a consistent folder, GRC system, ticket queue, or audit workspace so an assessor can trace the control from requirement to implementation to review.
Evidence Normally Gathered
Information Exchange: assessment plan.
Information Exchange: control test records.
Information Exchange: POA&M.
Information Exchange: continuous monitoring reports.
Information Exchange: information exchange agreements.
Information Exchange: remediation status reports.
Information Exchange: owner assignment and review cadence.
Information Exchange: exception, remediation, or POA&M records when the control is not fully implemented.
Common Auditor Questions
Where is information exchange implemented in the in-scope environment?
Who owns information exchange, and how do they know it is operating?
Show the evidence that proves information exchange ran during the assessment period.
What happens when information exchange fails, is bypassed, or has an exception?
How does this control connect to the system security plan, risk register, POA&M, and related CPCSC controls?
