Episode 62 — Firewall Configuration — Ports, Rules, and Access Control
This episode covers how to configure and manage server firewalls to control inbound and outbound traffic. We explain how rules are created based on IP addresses, protocols, and port numbers, and how these rules enforce access control to protect server resources. The discussion includes common firewall configurations for services such as HTTP, HTTPS, SSH, and RDP, and the difference between software firewalls and dedicated hardware appliances.
Real-world and exam-focused examples show how to open ports for required services, block unneeded traffic, and troubleshoot when legitimate traffic is accidentally blocked. We also highlight best practices for documenting firewall changes and implementing rule reviews to maintain security. Mastering firewall configuration prepares candidates to secure server communications and align with operational policies.
