What Is ISO 27001 and Why Is It Important for Businesses?
ISO 27001 is the international standard for Information Security Management Systems (ISMS). It outlines specific requirements for protecting data and IT systems, managing risks, and ensuring compliance.
For small and midsize businesses, ISO 27001 certification brings several key benefits:
Stronger trust with customers and partners
Fulfillment of regulatory requirements, e.g. GDPR
Demonstration of a systematic approach to information security
Reduced risks and minimized damage from security incidents
ISO 27001 Requirements for Identity and Access Management
Secure access control is a core component of ISO 27001. Organizations must implement an Access Management framework that addresses the following questions:
Who needs access to which IT systems and data?
How are access rights assigned, documented and reviewed?
How are physical and logical access points protected?
How is Segregation of Duties (SOD) maintained?
How are access requests, changes and revocations documented?
The standard mandates formalized processes, periodic reviews of access rights, and full audit trails to demonstrate compliance with the “Need-to-know” principle and data minimization.
Typical Pain Points: Why Is Access Management Often the Weak Link?
During audits, the same issues come up repeatedly, especially in midsize companies:
Fragmented Tools: Companies often use multiple disconnected systems without an unified view of access rights.
Lack of Automation: Authorizations are manually granted and revoked, leading to delays and errors.
Permission Creep: Employees accumulate excessive access rights over time due to role changes and project access that are never cleaned up.
High Operational Costs: Manual request handling consumes valuable IT resources.
Onboarding Delays: New hires often wait days for the access they need, slowing productivity and damaging employer branding.
Use Case: Access Rights for New Employees
Imagine a new hire joins your company – but can’t do their job because they don’t yet have access to systems and applications. In an age of digitalization and talent shortages, that’s unacceptable. Today’s top talent expects seamless IT processes from day one – starting with Identity & Access Management (IAM).
Step-by-Step: Build an ISO 27001-Compliant Access Control Policy
A structured, well-documented permission model is a cornerstone of any security strategy. An IAM solution helps you meet ISO 27001 certification requirements by standardizing, automating and documenting processes in an auditable way.
Here’s how to build a compliant model, step by step:
1. Initial Assessment and System Inventory
Identify all systems, applications and data requiring access control.
Document all users, roles and existing authorizations and entitlements.
2. Definition of Roles and Access Rights
Implement Role-Based Access Control (RBAC).
Clearly define which roles require what levels of access.
3. Processes for Provisioning and Deprovisioning
Standardize onboarding, role changes and offboarding workflows.
Integrate approval workflows and maintain full documentation to ensure regulatory compliance.
4. Regular Access Reviews and Recertifications
Periodically review and clean up outdated or excessive authorizations.
Document results in a fully auditable way.
5. Automation and Monitoring
Use tools like the Garancy Suite to automate access rights processes and meet compliance requirements efficiently.
Why Automation Is Essential: The Benefits of Modern IAM Tools
Why automate? Because automation delivers speed, reliability, and cost savings:
Faster provisioning: New hires receive access in minutes, not days
Fewer errors: Automated workflows reduce the risk of manual mistakes
Cost efficiency: Offloads routine work from IT and reduces process costs
Audit readiness: Every change of authorizations is logged – a must for ISO 27001 and GDPR
Seamless integration: Modern IAM tools fit easily into existing IT environments

Automated periodic recertifications to validate access rights
Centralized documentation and audit trails
Easy integration with existing IT and cloud infrastructure
ISO 27001 vs. Other Regulations: Comparison of Access Management Requirements
Access Management is a critical requirement across all major security and data privacy regulations. ISO 27001 plays a leading role with its focus on least privilege, privileged account management, and access control.
Here’s how ISO 27001 aligns with other key regulations:
Framework | Access Management Requirements | References |
|---|---|---|
ISO 27001 |
| Annex A.5.16, A.8.3, A.8.18, A.8.32, A.9 |
GDPR (EU General Data Protection Regulation) |
| Chapter 2 Art. 5.1; Chapter 4 Art. 32.1 & 32.1.3 |
BDSG (German Federal Data Protection Act) |
| Chapter 4 § 64.3.5 |
BSIG (Act on the Federal Office for Information Security) |
| All: § 8a & subsequent clarification of paragraph 1 |
NIS2 (Network and Information Security Directive) |
| A.11.1, A.11.2.2.a, A.11.2.2.e, A.11.3.2-3 |
Conclusion: Automation Is the Key to ISO 27001 Success
The Access Management requirements of ISO 27001 are strict – but with automated tools like the Garancy Suite, they become a competitive advantage. You’ll save time, cut costs, and set the foundation for a successful certification. That means you’re well-equipped to tackle talent shortages and future-proof your business.
