Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.
