Access control is among the most critical aspects of keeping data secure. Organisations must ensure that only the right people have access to the right information and that all other users are restricted. An ISO 27001-compliant access control policy is essential to achieving this objective.
Annex A.9 of ISO 27001 provides guidance on developing and documenting an access control policy for an information security management system (ISMS). This blog post will look at what should be included in an access control policy and how to write one that meets the ISO 27001 standard.
What is an Access Control Policy?
An access control policy is a set of rules that dictate who can access which resources in an information management system. The most basic form of an access control policy is a simple list of users and the resources they are allowed to access.
What Should an Access Control Policy Include?
When creating an access control policy, a few key elements should be included to ensure the policy is effective. First, the policy should identify individuals with privileged access to information, network, and network services within the organisation. These individuals or teams should be designated, and their contact information should be easily accessible.
The policy should also consider how you align your information scheme and security requirements. It would be best if you also list the types of data and systems covered by the policy. This will help to ensure that all sensitive information is appropriately protected.
Your access control policy should detail the procedures used to grant and revoke access to data and systems. A password management system, data encryption, and establishing secure log-on procedures can be suitable starting points. This will help ensure that only authorised individuals or information asset owners can access sensitive information.
Finally, the policy should specify how often it will be reviewed and updated. This will help ensure the system’s administration remains effective over time.
How to Write an Effective Access Control Policy
When it comes to writing an access control policy, there are a few things you’ll want to keep in mind to make it as effective as possible. Here are some tips:
- Keep it straightforward – Don’t try to get too fancy with the policy’s language or structure. Keep it concise and easy to understand.
- Tailor it to your specific needs – Every organisation is different, so your access control policy should be tailored to fit the needs of your particular business. There’s no “one size fits all” approach here. Ensure your policy aligns with business requirements and that everyone in the organisation knows what’s expected of them.
- Ensure it is comprehensive – An effective access control policy will determine what types of access are allowed and how they can be granted. It should also detail what happens if someone tries to access something they shouldn’t have.
Once you have your access control policy in place, ensure everyone in the organisation follows it. Having a policy is pointless if it is not being enforced.
