CPCSC Level 2 03.01.06: Least Privilege - Privileged Accounts

Apply least privilege - privileged accounts to control who can access in-scope systems, how information flows, and which access paths are allowed 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 03.01.06. Use the Cyber Centre publication and contract requirements as the source of truth for certification, assessment, or procurement submissions.

  • Restrict privileged accounts on the system to [Assignment: organization-defined personnel or roles].
  • Require that users (or roles) with privileged accounts use non-privileged accounts when accessing non-security functions or non-security information.
  • Require any administrative or superuser actions to be performed from a physical workstation which is dedicated to those specific tasks and isolated from all other functions and networks, especially any form of Internet access.

What This Means In Plain English

Least Privilege - Privileged Accounts is part of the CPCSC Level 2 Access control family. This is about making access decisions enforceable. The organization needs to know who can reach specified information, which systems can exchange it, and which access paths are approved.

For a founder, CISO, engineer, or compliance owner, the practical question is whether least privilege - privileged accounts 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 least privilege - privileged accounts.

2

Use identity groups, network rules, conditional access, remote-access approvals, data-flow boundaries, and exception records to make the access rule real in systems.

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.
