4. Segmented Network Access for Better Secure Remote Access
Even with a secure VPN, users should not have unrestricted access to the entire network. Access should be limited based on roles and responsibilities, with permissions managed through an access control list (ACL). Sensitive data should be isolated in separate VLANs, accessible only to authorized personnel.
Proper network segmentation also minimizes the potential impact of a breach. In the event of unauthorized access, isolating sensitive areas prevents lateral movement within the network. This proactive approach not only limits exposure but also provides critical time to identify and mitigate the intrusion.
