A firewall is a software or hardware appliance that protects networks from unauthorized access and intrusion. The most common use of firewalls is to protect networks from unauthorized access by external users.
Firewalls are also used to protect internal networks from unauthorized access by employees.
There are three types of firewalls: network-based, host-based, and application-based.
Network-based firewalls protect networks from unauthorized access by detecting and blocking incoming traffic. Host-based firewalls protect individual computers from unauthorized access by blocking access to specific ports on the computer.
Application-based firewalls protect specific applications from unauthorized access.
There are three types of network-based firewalls: packet-filtering firewalls, stateful firewalls, and proxy firewalls.
Packet-filtering firewalls filter traffic by inspecting the packets that are sent and received. Stateful firewalls keep track of the current state of each packet and allow or deny access based on the current state of the packet.
Proxy firewalls act as a middleman between the client and the server. The proxy firewall transparently transparently forwards requests from the client to the server and vice versa.
There are three types of host-based firewalls: host-based intrusion detection systems, host-based anti-virus systems, and host-based intrusion prevention systems.
Host-based intrusion detection systems detect malicious activity on the computer and report the findings to the firewall. Host-based anti-virus systems protect the computer from viruses by scanning the files that are sent and received.
Host-based intrusion prevention systems protect the computer from unauthorized access by preventing the unauthorized access of specific hosts or applications.
Application-based firewalls protect specific applications from unauthorized access.
Application-based firewalls are divided into two types: content filtering firewalls and application security firewalls.
Content filtering firewalls filter the content that is sent and received. Application security firewalls protect the applications that are installed on the computer by monitoring the activities of the applications.
Content filtering and application security firewalls are similar in that they both protect the applications that are installed on the computer. However, content filtering firewalls are limited in the types of applications that they can protect and application security firewalls are limited in the types of content that they can filter.
Content filtering firewalls are limited in the types of applications that they can protect.
Application security firewalls are limited in the types of content that they can filter.
Application-based firewalls are the most common type of firewall. Application-based firewalls protect specific applications from unauthorized access. Application security firewalls protect.
