VPNs create an encrypted tunnel through the perimeter firewall, allowing authenticated remote users to securely access internal network resources.

The incident response process typically begins with identification, where an organization detects and confirms a security incident. This initial phase involves monitoring systems, analyzing alerts, and determining if an actual breach or security event has occurred. Accurate identification is crucial for initiating the subsequent response steps.

Vulnerability scanning is a proactive security measure designed to identify weaknesses or flaws in computer systems, networks, and applications. Its main purpose is to systematically scan for known vulnerabilities that attackers could exploit. This assessment helps organizations understand their security posture and prioritize remediation efforts to prevent potential breaches.

A honeypot is a security mechanism designed to attract, trap, and study cyber attackers. It mimics a legitimate system or network resource but contains no real valuable data, serving as a decoy. By observing how attackers interact with the honeypot, organizations can gather intelligence on attack methods and improve their actual defenses without risking real assets.

The body of knowledge provides the framework guiding daily decision-making and practices.

The initial assessment establishes a baseline and identifies specific needs to guide subsequent decisions.
