Before starting discussing different techniques which are helpful while creating architecture of a secure system, it’s useful to go through the key concepts which must always be at primary concern of any software/hardware architect while thinking about security.
In this article we will go through the key concepts in information security and will try to explain them by bringing real life examples. Throughout the article I will also call the key concepts “security properties” of information.
