While an advanced firewall can no longer single-handedly defend a network against today’s complex cyber threat landscape, these devices are still considered to be the foundational building block for creating a proper cybersecurity system. Without firewalls, computers and devices in your network are susceptible to h ackers and make you an easy target for attacks. This prevents unauthorized users, devices, and applications from entering a protected network environment or segment. These rules can also prevent users within the network from accessing certain sites and programs.įirewalls are based on the simple idea that network traffic from less secure environments should be authenticated and inspected before moving to a more secure environment. Firewalls block incoming malware based on a set of pre-programmed rules. A firewall is a network security solution that protects your network from unwanted traffic.
