Firewall

Firewall is a network security device or software solution that monitors and controls incoming and outgoing network traffic based on predefined security rules or policies. It acts as a barrier between trusted internal networks and untrusted external networks, protecting systems and data from unauthorized access, malicious attacks, and network threats. Readers can explore firewall technologies, deployment strategies, and best practices for securing network infrastructure, enforcing access controls, and mitigating cybersecurity risks in modern IT environments, ensuring confidentiality, integrity, and availability of critical assets and services.
