Firewalls

Firewalls are essential security devices that are designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between a secure internal network and untrusted external networks, such as the internet, to protect against unauthorized access and cyberattacks. Firewalls can be hardware-based or software-based, working to prevent malicious activity and filter out potentially harmful traffic. By enforcing a set of security protocols and rules, firewalls help to safeguard sensitive information and assets from cyber threats. Implementing firewalls is crucial for organizations aiming to maintain a secure and protected network environment.
