In one sentence: Social engineering is when someone tricks a person, instead of breaking into a computer, to get information or access.
Why it matters: They may pretend to be someone you trust, such as a bank or a repair person. Anyone can be tricked, so falling for it is not a personal failure. Phishing is one kind of social engineering.
One thing to do: If someone you do not expect asks for information or money, stop. Check with them using a phone number or website you already know is real.
