Firewall Configuration

Firewall configuration is the process of setting up and managing firewall rules and policies to control network traffic based on security criteria. It involves defining which connections are allowed or blocked to protect systems from unauthorized access and cyber threats. This skill is essential for implementing network security in both on-premises and cloud environments.

Also known as: Firewall Setup, Firewall Management, Network Security Configuration, FW Config, Firewall Rules
