What is Network Access Monitoring?
Network Access Monitoring refers to the process of tracking and analyzing network traffic to ensure only authorized users and devices can access your organization's network resources. It involves continuously monitoring who is connecting to the network, what activities they are performing, and whether any suspicious or unauthorized access attempts are being made. The goal is to detect potential security threats in real-time, ensure compliance with security policies, and protect sensitive data from breaches. Effective network access monitoring tools provide detailed insights into user behavior, identify vulnerabilities, and help administrators enforce access control policies, ensuring a secure and optimized network environment.
