How to Completely Remove an Old User from Your Network? [Video]

When it comes to network management, overlooking an old user account can be both a security risk and an administrative hassle. Have you ever combed through your active directory and realized a former employee still has access? By the end of this article, you'll confidently navigate the process of removing old user accounts. 

Knowing how to effectively remove previous users from your network is a critical part of maintaining security and efficiency. Here, we outline a comprehensive strategy to achieve this, focusing on three core areas: Internal Active Directory, O365 (Microsoft's Office 365 suite), and Remote Access. 

Internal Active Directory and File Share Access 

Begin by disabling the user in your Active Directory. The goal here isn't just shutting down access but ensuring continuity where needed. Determine what files the former employee had access to and who needs those files now. It might be necessary to transition their manager or replacement to these resources. Double-check all servers to ensure any lingering session connections are fully closed. This step often coincides with HR's offboarding process and can significantly mitigate potential data access concerns. 

O365 (Office 365) 

O365, Microsoft's cloud suite, represents another layer of potential access that requires careful handling. Deactivate the user account and manage their licenses appropriately. Address the issue of what to do with their data—most notably their email. Transitioning it into a shared mailbox can offer seamless access to their team and superiors. It's also important to set up an appropriate email forwarding system for any future correspondence intended for the former employee. Pay attention to any data they stored on OneDrive or SharePoint, ensuring necessary parties gain access. 

Remote Access 

Remote access involves connection points into your network, like VPNs or remote desktop applications. If a user account remains active on your firewall for VPN access, it poses a considerable risk. Similarly, remove unauthorized remote desktop software from machines. This less-common step can prevent security breaches from applications like GoToMeeting or LogMeIn123 inadvertently left installed. 

Conclusion 

By following these three steps—disabling Active Directory and file server access, deactivating cloud services in O365, and securing remote access—you can protect your network from unwanted external threats.
