Firewall — CompTIA Security+ (SY0-701) Practice Questions
A firewall is a network security device or software that inspects traffic and enforces rules to permit or deny communications based on criteria such as IP address, port, protocol, or application. SY0-701 covers multiple firewall types including packet-filtering, stateful inspection, next-generation firewalls with application awareness and intrusion prevention, and web application firewalls. Candidates must understand firewall placement concepts such as screened subnets, DMZs, and network segmentation, as well as rule ordering and implicit deny principles. Firewalls are a foundational perimeter and internal control, and questions on this topic often appear alongside topics like network architecture, access control, and traffic filtering.
