This is accomplished by exploiting human tendencies and
emotions. Common tactics include phishing, pretexting, baiting, quid pro quo,
tailgating, and impersonation. For example, a social engineer may send a fake
email pretending to be from a trusted source to get login credentials. Or they
may pose as an authority figure to get access to a restricted area.
Social engineers are skilled at deception, persuasion, and
gaining people's trust. They do extensive research on targets to uncover
vulnerabilities and exploit them. An adept social engineer can gather enough
information to impersonate coworkers or authenticate themselves as legitimate
users.
Defending against social engineering requires vigilance,
skepticism, and policies that limit data access. Since the targets are people
rather than computer systems, technology alone cannot provide robust
protection. Fostering awareness of common tactics is key to avoiding
manipulation.
