A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its purpose is to establish a barrier between a trusted internal network and an untrusted external network, such as the Internet, to protect sensitive internal systems and data from unauthorized access, hacking attempts, malware, and other cyber threats.
Firewalls can be hardware-based, software-based, or a combination of both. They use various technologies, such as packet filtering, stateful inspection, and application-level proxy, to inspect network traffic and enforce security policies. They are an essential component of a comprehensive network security strategy and can help organizations to protect their systems, networks, and data from various security threats.
Network firewalls, also known as perimeter firewalls, are placed at the boundary between a trusted internal network and an untrusted external network, such as the Internet, to protect sensitive internal systems and data.
Host-based firewalls are installed on individual systems, such as servers and desktop computers, to protect those systems from external threats.
Next-generation firewalls are a type of network firewall that provide advanced security features, such as intrusion prevention, application control, and user identity-based policies.
Stateful inspection firewalls track the state of network connections and can make decisions based on the state of the connection, such as whether the connection is new or established.
Packet filtering firewalls inspect incoming and outgoing network packets and make decisions based on the information in the packet headers, such as the source and destination IP addresses and port numbers.
Application-level firewalls, also known as proxy firewalls, inspect and control network traffic at the application layer, allowing or blocking specific types of applications and their associated network traffic.
Cloud firewalls are firewalls designed for use in cloud computing environments, providing security for cloud-based resources and applications.
