A firewall acts as a barrier between your internal network and potential external threats, controlling incoming and outgoing traffic.
Understanding the different types of firewalls—hardware, software, and cloud firewalls—can help you choose the right protection.
To ensure your firewall is effective:
Establish rules to determine which traffic is permitted or denied.
Regularly monitor traffic logs to identify potential threats and adjust configurations accordingly.
While firewalls are essential, they should be part of a broader strategy that includes antivirus software, encryption, and employee training.
