Ranum contributed to the development of vital components of the firewall with its Firewall studies between 1991 and 1992. SEAL, which was referred to as proxy external access connection in 1991, was the first firewall released by Ranum.

Contributions of Nir Zuk and Gil Shwed to the System
Gil Shwed is the founder of Check Point. Nir Zuk is the person who worked as the development staff in the company. The duo, founder and developer, played an important role in the development of the firewall between 1993 and 1994. Shwed received the US patent for the Firewall system, while Nir Zuk made important studies on the graphical interface south korea telegram to make the use of the firewall much more practical. These developments played an important role in the modernization of the Firewall systems used today.


Why Is Firewall Important?
Unprotected networks are not secure against any traffic trying to access the system. Regardless of whether it is harmful or not, network traffic always needs to be monitored. With a modern mechanism, the correct and secure operation of the system can be ensured.

Connecting personal computers to other networks or the internet brings security issues to the agenda. In cases such as connecting to other networks or the internet, the device needs protection. Hacking, malicious software or online fraud activities are common dangers in this sense.

Once your device network is infiltrated by malicious people or software, your device can be accessed and various threats may occur. Therefore, we can say that your computer is at risk 24 hours a day. It is possible to eliminate these risks with a firewall system.

Within the scope of Covid-19 measures, the US federal agency has decided to work remotely. However, while doing this, very important vulnerabilities were detected in the system due to the weakness in the firewall. The most important disadvantage of the established system was the establishment of many outgoing connection points open to traffic. Therefore, it is very important to integrate the firewall into the system as well as to use it. This vulnerability experienced in 2020 was detected in a short time and the firewall architecture was rebuilt by the US federal agency. After the implementation of the new system, no negativity or security gap was observed in the firewall of the system.
