In this guide you will learn how to implement ISO 27001 Annex A 8.2 Privileged Access Rights and pass your audit from ISO 27001 Lead Auditor Stuart Barker – author of the ultimate ISO 27001 Toolkit.
ISO 27001 Privileged Access Rights
ISO 27001 Annex A 8.2 Privileged Access Rights is an ISO 27001 control that wants you to make sure you have controls in place to manage privileged access rights.
There are users that will be granted privileged access such as administer (admin) accounts, super user accounts, global admin accounts and even service accounts. ISO 27001 Privileged Access Rights is the control of those accounts.

Key Takeaways
- ISO 27001 Annex A 8.2 requires organisations to strictly manage and restrict privileged access rights.
- Privileged access (often called “Admin,” “Super User,” or “Root” access) allows users to bypass security controls, install software, and change system configurations.
- Because these accounts pose the highest risk of misuse or compromise, they must be governed by an authorisation process that follows the principles of Least Privilege and Need-to-Know.
Purpose & Definition
The purpose of ISO 27001 Annex A 8.2 Privileged Access Rights is to ensure only authorised users, software components and services are provided with privileged access rights.
The ISO 27001 standard defines ISO 27001 Annex A 8.2 Privileged Access Rights as:
The allocation and use of privileged access rights should be restricted and managed.

ISO 27001 Annex A 8.2 Requirements and Guidance
Privileged access is the access that people, software or services have that allows them to do things that normal users cannot do and that could cause the most harm. This level of access is used to manage and configure systems and to allow people to perform administrative tasks. We need people to have this level of access but we do not want everyone to have it. The risk of granting this level of access to someone that doesn’t know what to do with it or should not have it is that they could break something, stop something working or carry out activities that are, shall we say, bad.
Access Control Policy
Your starting point for this control is to implement a topic specific policy on access control and include in that policy your approach to privilege access.
Authorisation process
An authorisation process is required for all requests for access to organisational assets. Implement a process of authorisation that separates those requiring access from those that grant it. Keep a record of all accounts with privilege access. Consider placing time limits on their use or allocating expiry dates.
Role Based Access
I find the use of role based access as a technique is a great tool here. Understanding what roles you need, defining them and then allocating people to roles based on need.
Segregation of duty
When implementing this control use common sense and be practicable. We are working here on the principle of segregation of duty. We do not want the person with the access to authorise the access and where possible the person with access should not have conflicting access. Rather, separate out your privilege accounts logically where it makes sense and you are able to do so. An example would be to separate out those with the access to the databases from those with access to the logging and monitoring. This prevents things like that ability to do something then change the logs to cover it up.
Principle of Least Privilege
Access should be granted based on the principle of least privilege, meaning users only get the minimum access necessary for their role.
Principle of Need-to-Know
Users should only have access to information they need to perform their duties.
Access Control
Learning from previous tutorials and in particular ISO 27001 Annex A 5.18 Access Rights you will ensure proper access control proportionate to the risk posed by the access that is required.
Access Requirements Review
Regular reviews of people’s access should form part of your normal operating rhythm. This also applies to privilege accounts. A process to check who has what and if they still need it. Ideally this will be performed at least monthly.
Use of privilege accounts
Ideally we want a situation where privilege accounts are only used when needed to perform privileged actions and normal accounts are used in normal day to day operations for the user. It doesn’t have to be this, as this is best practice, but the ideal is some way to distinguish when the user is in privilege mode. It will reduce the likelihood of an information security incident.
This level of account really should be logged and monitored for audit purposes.
Generic privileged accounts
You should really discourage the use of generic administrative accounts. We want to be able to tie actions back to an individual. If you simple have to have a generic account then my recommendation is to manage it as an exception and record it in the risk register. Mange it via risk management, even if that is accepting the risk.
Check Your Work?
You buit it yourself. Maybe with AI. But will it pass the audit?
Don’t gamble – let a trained ISO 27001 auditor check your work.
How to implement ISO 27001 Annex A 8.2
Managing privileged access rights is a vital technical control for preventing unauthorised system-wide changes and mitigating the impact of potential security breaches. Follow these steps:
- Formalise Privileged Access Policies and Rules of Engagement
- Provision Granular Identity and Access Management (IAM) Roles
- Implement Just-In-Time (JIT) and Ephemeral Access
- Mandate Multi-Factor Authentication (MFA) and Secure Vaulting
- Execute Continuous Session Monitoring and SIEM Logging
- Revoke and Review Privileged Rights Periodically
How to pass the ISO 27001 Annex A 8.2 audit
Based on my experience this is the best practice approach to passing the audit of ISO 27001 Annex A 8.2 Privileged Access Rights.
- Have policies and procedures in place: Write, approve, implement and communicate the documentation required for privileged access rights.
- Assess your privilege use requirements and perform a risk assessment: Identify what your requirements are for privileged access and then perform a risk assessment.
- Implement controls proportionate to the risk posed: Based on the risk assessment implement controls proportionate that risk assessment and the needs of the business.
- Keep records: For audit purposes you will keep records. Examples of the records to keep include changes, updates, monitoring, review and audits.
- Test the controls that you have to make sure they are working: Perform internal audits that include the testing of the controls to ensure that they are working.
Top 3 mistakes and how to avoid them
The top 3 mistakes people make for ISO 27001 Annex A 8.2 are
- Having generic accounts: Having generic accounts is not always a bad thing but having them because you are lazy is. Try to eliminate them and where you do require them manage via risk management. This means recording them on the risk register and managing the risk, even if managing the risk is accepting the risk and recording the decision.
- Laptop Administrator Accounts: This common mistake actually relates to end points and the default position of providing all users administrative control over those devices by default. Again, this is usually lazy management and again, as above, if required manage it via risk management. Auditors check and will want a justification and don’t just do it because it is easy or you have always done it. This level of access really does negate a lot of the end point controls that you are going to rely on.
- Your document and version control is wrong: Keeping your document version control up to date, making sure that version numbers match where used, having a review evidenced in the last 12 months, having documents that have no comments in are all good practices.
ISO 27001 Annex A 8.2 FAQ
Privileged access refers to any account or role that can bypass standard security controls or alter system configurations. These are often referred to as the “keys to the kingdom.” Common examples include:
Domain Administrators: Users who can manage the entire network infrastructure.
Local Administrators: Users with full control over a specific endpoint or server.
Root Users: The highest level of access in Unix/Linux environments.
Service Accounts: Non-human accounts used by applications to run automated tasks with elevated rights.
Yes, separating standard and administrative accounts is a critical best practice for compliance. An individual should not use a privileged account for day-to-day activities like reading emails or browsing the web. Implementation involves:
Standard User Account: Used for 95% of daily work (email, document editing).
Admin Account: Used only when performing specific administrative tasks.
Risk Reduction: This prevents a phishing attack on a daily email from compromising the entire network via admin rights.
No, shared or generic accounts (e.g., “admin@company.com”) are strictly prohibited under best practice compliance. You must be able to attribute every privileged action to a specific human being. If a generic account is absolutely necessary for technical reasons:
Exception Management: It must be recorded in the risk register.
Compensating Controls: Use a “checkout” system or password vault (PAM) to log exactly who used the account and when.
Monitoring: Enable enhanced logging for these specific accounts.
Privileged access rights should be reviewed at least monthly, or upon any significant change in personnel. This frequency is higher than standard user reviews because the risk is significantly greater. The review process should verify:
Continued Business Need: Does the user still require this level of access?
Role Changes: Has the user moved to a department where this access is no longer needed?
Activity Logs: Has the account been dormant? (Dormant admin accounts should be disabled immediately).
Auditors will primarily look for the “who, when, and why” of your privileged accounts. Be prepared to produce the following evidence during your Stage 2 audit:
The List: An up-to-date inventory of all users with admin rights.
Authorization Records: Documented approval tickets or forms for when access was granted.
Access Reviews: Minutes or logs showing you reviewed these rights last month.
Audit Trails: Logs showing specific actions taken by an administrator on a specific date.
Segregation of Duties (SoD) ensures that no single person has total control over a critical process. In the context of Annex A 8.2, this prevents internal fraud and error. Examples include:
Approvals: The person requesting admin access cannot be the same person who approves it.
Audit Logs: Ideally, system administrators should not have permission to delete or modify the security logs that track their own actions.
