B. External assessment
Explanation:
The scenario describes a type of vulnerability assessment where a pen tester (Jude) examines a network from a hacker's perspective to identify exploits and vulnerabilities that are accessible to the outside world, such as through firewalls, routers, and servers. This type of assessment is called an external assessment.
External assessments are designed to simulate an attack from an external threat actor, such as a hacker or cybercriminal. The focus is on identifying vulnerabilities that are accessible from the Internet, such as open ports, unpatched software, weak passwords, and misconfigured systems.
External assessments typically involve a combination of automated scanning tools and manual testing techniques. The objective is to determine the level of security of the corporate network and estimate the threat of network security attacks.
