What is an example of social engineering?

The correct answer identifies a common tactic used in social engineering, which involves manipulating a person into divulging confidential information. Social engineering exploits human psychology rather than relying on technical hacking methods. This can include techniques such as phishing, where attackers pose as trustworthy entities to lure individuals into providing sensitive data like passwords or credit card numbers.

By understanding the nature of social engineering, it becomes clear that it relies heavily on deception and psychological tricks rather than technological vulnerabilities. The other options focus on technical skills or the development of secure systems, which are not related to the manipulation of individuals in the same way social engineering tactics are.
