A firewall is a device or application that is used to protect computer networks and data from unauthorized access. Firewalls work by allowing only authorized traffic to pass through them, while blocking all other traffic.
A firewall is composed of three main components: a policy engine, a detection and blocking engine, and a communication interface. The policy engine decides which traffic to allow and which to block.
The detection and blocking engine is responsible for identifying and blocking malicious traffic. The communication interface is responsible for sending and receiving traffic.
Firewalls can be implemented on a single computer or across a network of computers. A single firewall can protect a single computer or a network of computers.
A network firewall is a type of firewall that protects a network of computers from unauthorized access.
Firewalls can be categorized according to the type of traffic they protect. A firewall can be a network security appliance, a host security appliance, or a intrusion detection system.
A network security appliance is a type of firewall that protects a network of computers from unauthorized access. Network security appliances protect networks by identifying and blocking unauthorized traffic, by monitoring traffic for malicious activity, and by enforcing security policies.
A host security appliance is a type of firewall that protects a single computer from unauthorized access. Host security appliances protect computers by blocking unauthorized traffic, by monitoring traffic for malicious activity, and by enforcing security policies.
An intrusion detection system is a type of firewall that protects a network from unauthorized access. An intrusion detection system monitors network traffic for signs of unauthorized activity and notifies administrators of these signs.
