Dumpster Diving

Searching trash for discarded information or media that can aid an attack.

Definition

Documents, sticky notes, old hard drives and printed org charts can reveal credentials, names and internal details. Shredding, secure disposal bins and media sanitization policies prevent it. In many jurisdictions trash placed for collection has limited legal privacy protection.

Example

Finding printed network diagrams in a company's recycling bin.

Exam tip

Cross-cut shredding and secure media destruction are the expected controls.
