Which threat type involves an unauthorized individual gaining access to a network?

• A. Password attacks
• B. Denial of Service attacks
• C. Profiling
• D. Unauthorized access

Answer: (D)

The correct answer is unauthorized access, as this term specifically refers to an unauthorized individual gaining entry into a network or system without permission. This can occur through various means such as exploiting vulnerabilities, using stolen credentials, or bypassing security measures. In the context of network security, unauthorized access poses significant risks, as it can lead to data breaches, theft of sensitive information, and other malicious activities. Other options like password attacks involve specific techniques aimed at compromising passwords to gain access but do not universally cover all methods of unauthorized access. Denial of Service attacks focus on overwhelming a network or service to make it unavailable rather than gaining access. Profiling typically refers to gathering information about a system or user, which can be a precursor to unauthorized access but is not itself an access method. Thus, unauthorized access is the most accurate term for describing the threat of an individual illegally entering a network.
