Social Engineering

Social engineering is the practice of individuals to use flattery, conning, impersonation, and other methods to encourage uneducated users into giving up information.
It bypasses the best technology protections which makes it important for all users to understand. It's often just people talking to one another - either directly, or via the phone - without using technology at all. It can also be done via email using phishing tactics.
Common social engineering tactics are:

►    Phishing

►    Piggybacking or tailgating

►    Impersonation

►    Dumpster diving

►    Shoulder surfing
