Which of the following is a common term for unauthorized access to organizational resources?

The term "hacking" specifically refers to unauthorized access to organizational resources or systems. It typically involves exploiting vulnerabilities within digital systems to manipulate, retrieve, or destroy data without permission. Hacking can range from non-malicious activities, such as ethical hacking aimed at finding and fixing vulnerabilities, to malicious activities intended to cause harm or steal sensitive information.

This term encompasses various techniques and methods that can be used to gain access, including exploiting software vulnerabilities, using malware, or bypassing security measures. Given the context of unauthorized access, hacking is the most fitting term among the options provided because it defines the act of gaining access without proper authorization, reflecting the core of the query accurately.

Other options, like phishing and social engineering, while related to security threats, do not broadly cover unauthorized access in the same way. Phishing specifically involves tricking individuals into providing sensitive information, whereas social engineering encompasses a range of manipulative techniques to exploit human psychology, not solely restricted to access issues. An insider threat refers to dangers posed by individuals within the organization who have legitimate access but may misuse that access, which is distinct from general unauthorized access scenarios typically associated with hacking.
