Question

Accepted Answer

Firewalls are security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules.

Types of firewalls include: Packet Filtering, Stateful Inspection, Proxy Firewalls, and Next-Generation Firewalls.
A firewall acts as a barrier between trusted and untrusted networks, preventing unauthorized access.
Stateful firewalls track the state of active connections, while stateless firewalls treat each packet in isolation.
Hardware firewalls are standalone devices, while software firewalls are installed on individual computers or servers.
Firewall rules can be configured through a management interface, specifying allowed or denied traffic based on IP addresses, ports, and protocols.
