Control of documented information
Plain English Translation
Clause 7.5.3 mandates that all documents required for your security program must be effectively managed throughout their lifecycle. You must ensure that documents are available to the people who need them when they need them, while simultaneously protecting them from unauthorized changes or leaks. This involves establishing rules for how files are distributed, stored, accessed, updated (version control), and eventually destroyed when no longer needed.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Store policies in a central cloud drive (Google Drive/OneDrive) with 'Read-Only' links for staff
- Enable native version history features on the cloud platform
- Define a basic retention rule (e.g., 'keep everything indefinitely' or 'delete after 3 years')
Required Actions (scaleup)
- Implement access reviews to ensure only current employees have access to documentation
- Use tagging to classify documents (e.g., Internal, Confidential)
- Formalize the retention schedule in a policy addendum
Required Actions (enterprise)
- Deploy Data Loss Prevention (DLP) tools to prevent downloading of sensitive docs
- Automate document lifecycle workflows (approval -> publish -> archive -> delete)
- Integrate document control with GRC platforms for automated evidence collection
It is the requirement to manage ISMS documentation to ensure it is available, suitable, and protected. It covers distribution, access, storage, version control, and retention.
By implementing a document management system or process that restricts access based on roles, tracks version history, ensures backups, and defines how long documents are kept.
The standard requires you to address: distribution, access, retrieval, use, storage, preservation (legibility), control of changes (versioning), and retention/disposition.
Use access controls (e.g., read-only for most staff), encryption for storage, regular backups to prevent loss, and audit logs to track who accessed sensitive documents.
Clause 7.5.2 deals with the creation and update process (formatting, approval). Clause 7.5.3 deals with the ongoing control and lifecycle (storage, access, retention) of those documents.
Store documents in a central, known location (like an Intranet or Wiki) that is accessible to all relevant staff, and review them regularly to ensure they remain accurate and relevant.
You must define who can view (read) versus who can edit (write/approve) documents. Sensitive documents (like audit reports) should have stricter access than general policies.
Retention periods depend on the type of document and legal/business requirements. For example, policies might be kept permanently, while access logs might be kept for 1 year.
Auditors typically want to see that documents are controlled (approved, versioned, access-restricted) and that you can quickly produce evidence of how the process works. WatchDog Security's Compliance Center can help by linking document-control controls to mapped evidence requests, tracking approvals and recency, and surfacing gaps (e.g., missing owners, outdated policies, or incomplete review cycles) so you can demonstrate a repeatable, auditable process.
Effective document control is not just storing files—it includes knowing which version is current, who approved it, and whether impacted staff have reviewed the latest guidance. WatchDog Security's Policy Management can help by maintaining controlled policy versions, tracking review/approval status, and recording acceptance attestations so you can show that the right people received and acknowledged the current, approved documents.
"Documented information required by the information security management system and by this document shall be controlled to ensure: a) it is available and suitable for use, where and when it is needed; and b) it is adequately protected (e.g. from loss of confidentiality, improper use, or loss of integrity)."
