Because it outperforms firewalls, cryptographic techniques, intrusion detection systems, and antivirus software, social engineering presents a serious threat to network security. Attackers are always looking for new ways to get past security measures, and their creativity keeps up with these developments. Humans are frequently the weakest link in the security chain because of our innate tendency to trust one another. Through psychological manipulation, malicious operations carried out through human interactions persuade people to provide private information or circumvent security measures. Thus, human nature and negligence are the key determinants in executing cyber-attacks. Social engineering assaults are powerful dangers that can damage any system or network because of how commonplace these human-driven interactions are. Such assaults cannot be stopped by conventional software or hardware solutions unless people are properly taught to identify and stop them. Systems for cybersecurity include people. Humans will always be involved until we achieve real artificial intelligence, if we can and should. Therefore, just like any other piece of technology in the system, humans also need to be understood. It’s critical to comprehend the evolution of the human mind, its strengths, and its weaknesses. Humans are not likely to change much, which is one way they differ from the other technologies in a system. We constantly create new technologies with novel structures and functionalities. Naturally, this is not feasible for human brains. This implies that other technologies must adapt to the brain, not the other way around, to increase a system’s effectiveness. Cybersecurity experts should be interested in two topics: the psychology of manipulation and the psychology of error.
