How to Create a Checklist for Revoking Access to Company Systems

In any organization, controlling access to company systems is a crucial aspect of ensuring data security, compliance, and maintaining the integrity of operations. Employees, contractors, and third-party vendors often have access to various systems and resources to perform their jobs, but when they leave the company or no longer need access, it's essential to ensure that all permissions are revoked in a timely and thorough manner. Failure to do so can lead to data breaches, unauthorized access, and even legal and regulatory issues.

Creating a checklist for revoking access to company systems is a necessary practice that helps organizations systematically and securely remove access without missing any critical steps. In this guide, we'll walk through how to create an actionable checklist for this process, focusing on the best practices to maintain security and compliance.

Identify Access Levels and Systems

The first step in creating an effective checklist is to understand the scope of the access that needs to be revoked. Different employees, contractors, and vendors may have varying levels of access to different systems within your organization. It's crucial to have a comprehensive inventory of systems, applications, and tools used across your company.

Steps:

• List all company systems: Identify the systems, networks, applications, cloud services, and internal tools that employees have access to. This includes email accounts, project management tools, CRM systems, document storage, communication platforms, and any other business-critical systems.
• Categorize access levels: Define the different access levels within each system (admin, user, guest, etc.). Ensure you have a clear record of who has access to each system and the level of permission they have.
• Include physical access: If employees have physical access to company buildings, servers, or equipment, be sure to account for this as well.

Understanding the full scope of access is crucial for making sure nothing is overlooked in the revocation process.

Define the Revocation Triggers

Access revocation doesn't just happen when someone leaves the company; there are other scenarios in which revoking access is necessary. The checklist should identify these triggers so that revocation can be proactive and timely.

Common Triggers for Revoking Access:

• Employee resignation or termination: The most obvious trigger. When an employee resigns, is laid off, or is terminated, access needs to be revoked immediately.
• Contract expiration or change in role: Contractors or external vendors might have access to systems for a specific project or period. When their contract ends or their role changes, access should be revoked.
• Security incidents or breaches: If an account is compromised or there's a security breach, access to all affected systems should be revoked immediately to prevent further damage.
• Promotion or change in duties: If an employee is promoted or their responsibilities change, their access level may need to be updated or restricted to match their new role.

By clearly defining these triggers, the checklist ensures that access is revoked at the right time and for the right reasons, helping to prevent any potential security risks.

Establish a Step-by-Step Revocation Process

Once you have identified the systems and access levels, as well as the triggers for revocation, it's time to develop a clear, step-by-step process for revoking access. The process should be thorough, systematic, and ensure that all systems are covered.

A Sample Step-by-Step Process for Revoking Access:

1. Notification and Documentation:

   • Ensure the departure or role change is officially documented (resignation letter, termination notice, etc.).
   • Inform relevant team members (HR, IT, security) of the access revocation need.

2. Revoke Access to Email Accounts:

   • Disable or delete the user's email account across all platforms (corporate email, shared inboxes, etc.).
   • Ensure that any forwarding or access rights to the account are disabled.

3. Revoke Access to Internal Systems:

   • For each system on your list, revoke access to any accounts associated with the user. This includes project management tools, CRM systems, collaboration platforms, and internal databases.
   • Ensure user permissions are updated or removed across all cloud services, networked drives, or business-critical systems.
   • Disable or delete login credentials associated with the user, ensuring no residual access.

4. Revoke Access to Physical Devices and Systems:

   • Collect and disable any company-issued devices (laptops, mobile phones, access cards, security badges, etc.).
   • Ensure access to physical premises is removed by deactivating entry cards or disabling door access codes.
   • Retrieve any company-owned equipment that the user had access to.

5. Revoke Access to External Systems and Third-Party Tools:

   • Disable access to any third-party services or cloud storage solutions (e.g., Dropbox, Google Drive, etc.).
   • Deactivate or transfer ownership of any external vendor tools or accounts that the user managed or had access to.

6. Monitor System Logs and Activities:

   • Monitor system activity logs to ensure that there's no suspicious activity after access is revoked. This includes checking for any unapproved logins or data access attempts.

7. Notify Relevant Stakeholders:

   • Notify HR, managers, and any relevant stakeholders that the process of revoking access has been completed.
   • Inform the user's colleagues or team members of the access changes, especially if the transition is part of a role change.

Automate the Process Where Possible

To ensure consistency and efficiency, consider automating parts of the access revocation process. Automation tools and identity management platforms can help streamline the process, reducing the risk of human error and ensuring a faster response time.

Tools and Technologies to Automate Revocation:

• Identity and Access Management (IAM) Systems: IAM tools such as Okta, Azure Active Directory, or OneLogin allow you to manage user identities and access permissions centrally. These tools can automate the process of disabling user accounts across multiple systems.
• Single Sign-On (SSO) Solutions: Implementing SSO enables you to control access to multiple systems through a single authentication process. When access is revoked at the SSO level, it automatically revokes access to all connected applications.
• Security Information and Event Management (SIEM) Systems: These systems help monitor and manage security events and activities in real time, making it easier to spot any unauthorized access after revocation.

By automating certain steps of the revocation process, you can reduce the chances of leaving any system unprotected, especially when handling multiple employees or contractors at once.

Create a Comprehensive Audit Trail

An audit trail of all access revocation activities is vital for maintaining security and ensuring compliance with regulations. Depending on your industry, you may be required to maintain documentation and logs for auditing purposes. An audit trail not only serves as a record of what actions were taken, but it also helps you track and verify that the revocation process was carried out effectively.

What to Include in an Audit Trail:

• Date and time of access revocation: Document when each access point was disabled or modified.
• Systems and services affected: Record which specific systems or platforms the user had access to, and confirm each one was revoked.
• Reason for revocation: Note the reason for the revocation (resignation, termination, role change, etc.).
• Person responsible for revocation: Track who within your organization carried out the revocation process.
• Confirmation of completion: Include confirmation that all access points have been successfully revoked.

Having an audit trail ensures you can provide evidence of proper access management and meet compliance requirements, especially in regulated industries.

Communicate the Process to All Stakeholders

The final step in creating a checklist is to ensure that all stakeholders are aware of the revocation process. This includes HR, IT, security teams, and managers. Having a clear understanding of their responsibilities and roles in the process ensures a coordinated and efficient approach.

Best Practices for Communication:

• Create a policy document: Document the access revocation policy and ensure that all relevant employees are familiar with it. This document should outline procedures, timelines, and who is responsible for each step.
• Training and awareness: Conduct periodic training for HR and IT teams on the importance of access management and the proper use of the revocation checklist.
• Regular audits: Perform regular audits of access control practices to ensure the checklist is being followed and that there are no gaps in access management.

Clear communication and awareness among stakeholders ensure that access revocation is handled effectively and consistently across your organization.

Conclusion

Creating a checklist for revoking access to company systems is a critical component of your organization's security and operational integrity. By systematically documenting the necessary steps, understanding the triggers for access revocation, and leveraging automation tools, you can ensure a thorough and efficient process. Regular audits, clear communication, and a well-maintained audit trail are also essential for maintaining compliance and security.

Ultimately, a well-crafted access revocation checklist protects your company from security breaches, reduces the risk of data leaks, and helps maintain a safe and secure working environment.
