Egress Filtering Definition: Monitoring outbound traffic to prevent unauthorized data transfers.
Egress Filtering is the practice of monitoring and controlling outbound network traffic to prevent unauthorized or malicious data transfers. It helps ensure that only legitimate, policy-compliant connections leave the network, reducing the risk of data exfiltration, malware communications, or unauthorized access to external resources. Egress filtering often involves firewalls, proxies, or other network security devices that inspect outbound traffic based on IP addresses, ports, or content.
