Dumpster diving is the act of looking for treasure in someone else’s trash. In the world of information technology, dumpster diving is a technique used to retrieve information that could be used to carry out an attack on a computer network. Dumpster diving isn’t limited to searching through the trash for obvious treasures like access codes or passwords written down on sticky notes. Seemingly innocent information like a phone list, calendar, or organizational chart can be used to assist an attacker using social engineering techniques to gain access to a network. To prevent dumpster divers from learning anything valuable from your trash, establish a routine where all sensitive paper (like your bank statement) is shredded in a cross-cut shredder before being recycled. Also, make sure all storage media (CD, DVD, Floppy) is erased before discarding.
