With data at rest, a system application can suffer a security breach and an unauthorized intruder could deploy malicious code that corrupts the data or underlying programming code. In both instances the intrusion is malicious and the effects on the data always dire. Woah-Woah...WAIT!!! I know that this example is a little bit complicated but mind my words it will definitely help you to learn about this major security threat. Note:- You ca...
Anybody see on the subway, " Link your MetroCard to your debit card," right? Like,auto-refill? This is a concept which is key to everything we'll talk about today. And it's called linkability: Take one piece of data and link it to another piece of data.

When you then take cell phone data, which logs your location, and you lin...
