ISO 27002:2022 5.35: Independent review of information security
How the organization manages information security, and how that is carried out through people, processes and technology, is to be examined by someone independent on a planned cycle and whenever a significant change occurs. Purpose: keep the way information security is managed suitable, adequate and effective over time. Guidance: have processes for independent review, which management plans and initiates periodically. Reviews assess improvement opportunities and whether the approach needs changing, covering the top-level policy, the topic policies and the other controls. Reviewers are independent of the area reviewed (for example internal audit, a manager from elsewhere or a specialist external firm), competent, and outside the line of authority for that area. Results go to the management that commissioned the review and, where appropriate, to top management, and records are kept. Where a review finds the approach or implementation inadequate, for example objectives and requirements not met or practice not in line with the policies (5.1), management starts corrective action. Beyond the periodic cycle, consider an independent review when relevant laws and regulations change, after significant incidents, when a new business is started or an existing one changes, when a product or service is newly adopted or used differently, and when security controls and procedures change substantially. Guidance on conducting such reviews is in ISO/IEC 27007 and in ISO/IEC TS 27008.
This control maps to 163 controls across 48 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-GV.OV-01 Cybersecurity risk management strategy outcomes are reviewed to inform and adjust strategy and direction
NIST-CSF-GV.OV-02 The cybersecurity risk management strategy is reviewed and adjusted to ensure coverage of organizational requirements and risks
NIST-CSF-GV.OV-03 Organizational cybersecurity risk management performance is evaluated and reviewed for adjustments needed
NIST-CSF-GV.RM-03 Cybersecurity risk management activities and outcomes are included in enterprise risk management processes
NIST-CSF-ID.IM-02 Improvements are identified from security tests and exercises, including those done in coordination with suppliers and relevant third parties
NIST-CSF-ID.RA-08 Processes for receiving, analyzing, and responding to vulnerability disclosures are established
NIST-CSF-ID.RA-09 The authenticity and integrity of hardware and software are assessed prior to acquisition and use
You are reading one control. How much of ISO 27002:2022 have you already done?
ISO 27002:2022 5.35 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27002:2022 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 79 of 93 ISO 27002:2022 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 180 were rejected on the NIST SP 800-53 Rev 5 pair alone.
