"Testing the network using the same methodologies and tools employed by attackers" Identify the correct terminology that defines the above statement.

Vulnerability scanning is an automated, non-exploitative process that identifies known weaknesses through probing, without actively employing attacker tools or attempting to exploit findings.

Penetration testing is formally defined as the authorized simulation of real-world attacks against a system or network using the same tools, techniques, and procedures employed by malicious threat actors. Unlike passive scanning, penetration testing actively attempts exploitation to confirm whether vulnerabilities are genuinely exploitable and to measure real security posture. The phrase 'same methodologies and tools employed by attackers' is the core differentiator that defines penetration testing over all other assessment types.

Security policy implementation involves developing and enforcing organizational rules and standards, not actively testing systems with offensive techniques.

Designing network security refers to the planning and architectural phase of building secure infrastructure, which is a proactive design activity rather than adversarial testing.
