Analogy

Imagine a thief who wants to break into a secure building. Instead of trying to pick the lock or bypass the security systems, the thief decides to trick an employee into opening the door for them. They pretend to be a delivery person and convince the employee that they need access to the building. The employee, thinking they are helping a legitimate person, opens the door and unknowingly allows the thief to gain unauthorized access. This is similar to how social engineering works, where attackers manipulate individuals to gain access to sensitive information or secure facilities.
