Data Leak - What is it, Prevention and Solutions

Introduction to Data Leak

Information is power, it always has been. Wars have been won and lost based on intel gained and lost. Physical information and data are what led to the invention of espionage and spies.

Over the years, as with everything else, information has shifted to the digital space too. Now, most sensitive data is encrypted and stored either on a remote database or on a cloud, either way, accessible through computers.

What are Data Leaks?
