Network security monitoring is the continuous inspection of traffic patterns, firewall configurations, and access controls at the network layer. Attackers who gain a foothold on one system typically move laterally across the network before deploying ransomware or exfiltrating data. Network monitoring detects this lateral movement and the anomalous traffic patterns that indicate an active intrusion — often before the attacker achieves their objective.

BoTech reviews firewall configurations quarterly to identify unnecessary open ports, overly permissive rules, and rule sets that have not been reviewed in over a year. Network segmentation is verified to confirm ePHI systems are isolated from general business networks. Traffic anomalies identified through the SIEM feed into the MDR process for investigation. Remote access is restricted to MFA-protected VPN with access logging enabled.
