Instead of focusing heavily on abstract reasoning like the SAT, the ACT was designed to reflect the…

What is Social Engineering? Social engineering is a manipulation technique that exploits human psychology to gain confidential information, access systems, or perform unauthorized actions. Unlike conventional cyberattacks that target system vulnerabilities through code, malware, or brute force methods, social engineering targets the people who use those systems. It is based on the premise that people are the weakest link in the security chain. In essence, social engineering is the art of exploiting trust. It preys on natural human tendencies – like helpfulness, fear, urgency, or obedience to authority – to…
