Social Engineering

Social engineering is a collection of techniques used to manipulate people into performing actions or divulging confidential information

Social engineering takes advantage of the lack of concern for security in the daily lives of most people. An attacker can spend time at work or leisure getting to know users and gaining their confidence. While an attacker asks questions and gains information that on a per-answer basis does not appear harmful, the information taken as a whole provides the attacker with the means to start or carry out an attack.
