Building an Audit-Ready Document Library in SharePoint

The ISO 27001 documentation guide for stress-free audits

The audit is in two weeks.

The auditor asks for your risk register.
Then your Statement of Applicability.
Then last year’s access control policy.

Files are scattered.
Versions conflict.
Permissions are unclear.

This is how audits go sideways.

ISO 27001 does not fail organizations. Poor documentation management does.
A well-structured SharePoint library changes everything.

Why ISO 27001 Audits Fail on Documentation

Most organizations have the right documents.

They just cannot find them.

Common problems include:

  • Policies stored across multiple folders
  • Outdated versions mixed with current ones
  • No clear ownership
  • Over-permissioned access
  • No audit trail

 Auditors do not want excuses. They want evidence.

Why SharePoint Is Ideal for ISO 27001 Documentation

SharePoint is already trusted.

It offers:

  • Centralized storage
  • Version control
  • Metadata
  • Access permissions
  • Audit history

When configured correctly, SharePoint becomes your single source of truth for the ISMS.
Not just a file dump.

Quick Snapshot: ISO 27001 + SharePoint

Category Details
Primary goal Centralize and control ISMS documentation
Key benefit Fast, confident audit responses
Best for Organizations using Microsoft 365
Critical features Versioning, permissions, metadata
Audit outcome Clear, current, and traceable evidence

Step 1: Create a Central ISMS Document Library

Start with one rule.

One library. One purpose.

Create a dedicated SharePoint document library called:

Information Security Management System (ISMS)

This avoids confusion and scope creep.
Everything ISO 27001-related lives here.

Step 2: Design a Folder Structure Auditors Understand

Keep it simple.
Avoid deep nesting.

A proven structure looks like this:

01 – ISMS Governance
02 – Risk Management
03 – Policies
04 – Procedures
05 – Annex A Controls
06 – Statement of Applicability
07 – Internal Audits
08 – Management Reviews
09 – Incidents and Corrective Actions

 Auditors recognize this instantly. Clarity builds confidence.

Step 3: Map Folders to ISO 27001 Requirements

Each folder should align with ISO clauses and controls.
For example:

Folder What belongs inside
Risk Management Risk assessment, risk register, risk treatment plan, approvals
Annex A Controls Control evidence: screenshots, logs, config exports, tickets, test results
Management Reviews Agendas, minutes, decisions, KPIs, risk acceptance, improvement actions

This creates a direct audit trail.

If your current document structure feels messy, fix it before the auditor finds the gaps.

Step 4: Use Metadata Instead of Overloading Folders

Folders show where a document lives.
Metadata shows what it is.

Create metadata fields such as:

  • Document type (Policy, Procedure, Record)
  • ISO clause reference
  • Control owner
  • Review frequency
  • Status (Draft, Approved, Archived)

Metadata lets you filter during audits.
No searching. No guessing.

Step 5: Enable Version History (Non-Negotiable)

ISO 27001 expects controlled documents.
SharePoint version history provides:

  • Change tracking
  • Rollback capability
  • Proof of updates

Best practice:

  • Enable major and minor versions
  • Require check-in/check-out
  • Disable deletion for key documents

Auditors love version history because it proves control.

Step 6: Apply Role-Based Access Permissions

Not everyone needs edit access.
ISO 27001 requires controlled access.

Use role-based permissions such as:

  • Read-only for most staff
  • Edit access for ISMS owners
  • Approval rights for management

 Never use “Everyone can edit.” That is an audit finding waiting to happen.

Step 7: Assign Ownership to Every Document

Every document must have an owner.
Not a department. A person.

Capture ownership details using metadata or document properties:

  • Document owner
  • Approver
  • Next review date

Auditors will ask: “Who is responsible for this?” Have the answer ready.

Step 8: Set Review and Approval Workflows

Policies must be reviewed regularly.

SharePoint workflows help by:

  • Triggering review reminders
  • Capturing approvals
  • Preventing outdated documents from staying “active”

This proves continuous improvement, a core ISO 27001 requirement.

Still tracking reviews manually? Automate your ISMS documentation and reduce audit prep time.

Step 9: Prepare an “Audit View” for Fast Retrieval

Before the audit, set up retrieval like a dashboard.

Use:

  • Filters
  • Saved views
  • Grouping by ISO clause or document type

During the audit, you should be able to:

  • Find any document in seconds
  • Show version history instantly
  • Demonstrate control ownership

Speed signals maturity.

Common SharePoint Mistakes That Auditors Flag

Avoid these at all costs:

  • Duplicate libraries
  • Personal OneDrive storage
  • No versioning
  • Over-permissioned folders
  • Missing approval records

These are easy findings. And easy to prevent.
