Network security protects systems and data from unauthorized access and cyber threats. As businesses become increasingly digital, understanding security fundamentals is essential for everyone.
Firewalls act as barriers between trusted internal networks and untrusted external networks. They filter traffic based on predetermined security rules, blocking potentially harmful connections while allowing legitimate traffic.
Regular security updates patch vulnerabilities that hackers exploit. Enable automatic updates whenever possible and prioritize critical security patches. Outdated software is one of the most common entry points for cyber attacks.
