Firewalls

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Think of it as a barrier that protects your computer or network from unauthorized access, much like a security guard at a building entrance. Firewalls can be hardware devices or software applications, and they help prevent cyber threats like viruses and hackers from accessing sensitive information. By allowing only safe connections and blocking harmful ones, firewalls play a crucial role in maintaining the security and integrity of our digital environments.
