The need for firewall software is increasing day by day with the spread and development of the Internet and malware, and firewalls have become an important part of the network security of every system. Firewalls are software that is placed like a wall between the external and internal networks and ensure the security of computers against damage and threats such as cyber-attacks and the entry of viruses and trojans.
