๐ Topic Summary
Firewalls are essential security systems that monitor and control network traffic, acting as a barrier between a trusted internal network and untrusted external networks, such as the internet. They operate by examining incoming and outgoing network traffic based on pre-defined security rules. Firewalls can be hardware, software, or a combination of both. Effective network security also involves implementing best practices like regular software updates, strong password policies, and employee training to mitigate potential threats.
