WHAT IS A FIREWALL AND HOW DOES IT WORK?

How Firewall Software Works

Firewall, an English term translated into Turkish as "security wall," helps control the traffic entering and exiting a network. This software, which directs traffic to the correct destination within predefined communication rules, detects secure and insecure files and behaviors. Since behaviors and files are predetermined in firewall software, it becomes easier to detect any threat instantly. Systems identified as rules automatically pass through the firewall. Files and behaviors perceived as threats are blocked. Those who wish to benefit from this software can utilize addresses like , which maximize security measures in digital transformation.

How Firewall Software Operates

In firewall software, which automatically intervenes in the access of predefined behaviors and files, traffic not on the safe list can be exceptionally allowed based on the network user's request. In this system with a simple operating logic, traffic already on the safe list encounters no obstacles. However, access to traffic not on the safe list is blocked. Networks posing a security threat are blocked, and the user is notified. Firewall software can be used alone or can operate with the assistance of a server. In systems operating with a server, incoming and outgoing traffic is controlled by the server. The server, which checks the compliance of the traffic with security criteria, provides an extra advantage to its user. Thus, access to insecure traffic is prevented in a much healthier way.
