Phishing - social engineering with a bit of spoofing - usually spoofing a sender name/email format

• You can usually spot fakes by viewing the email address

Shoulder surfing - someone views sensitive information on a device from behind you or afar

Tailgating - Trailing an authorized user into a building against their knowledge

Piggybacking - When an authorized user knowingly helps you into a building

Sensitive information is often disposed of in dumpsters. This poses a security risk as dumpsters are typically unlocked and people dumpster dive

• In the US, dumpster diving is legal, assuming that it is on public property and no local code prohibits it
