More Information
Firewalls not only protect networks by filtering incoming and outgoing traffic but also organize network traffic to identify and halt any suspicious or harmful data packages. They can be software-based, hardware-based, or a combination of both.
Tips
A common mistake is assuming firewalls alone provide complete security. They should be part of a comprehensive security strategy.
