In the software world, all software either fulfills some or all of the design principles. These principles help eliminate security risks, and support better performance at the time of maintenance. They also reduce the chances of conflict in security policies while integrating with other software or services. Specific design principles directly control the design and implementation of mechanisms for supporting security policies. These principles are built on the ideas of simplicity and restriction. Simple designs are always easy to understand and they support redesign if needed. It can also be understood and explained easily, which reduces the cost and time. In addition, with simple designs the chances of errors are also minimal. It also makes the interconnection process smooth and simple since it is always easy to track different connections with another system if the design is kept simple and transparent.
