Contrary to the perception, experts are now of the opinion that security cannot be feasibly added into an exiting system. It is an emergent property that requires advance planning during requirements phase with careful design. Earlier Software Security was an after thought, which used to compound itself during later stages.
Generally, it used to be taken as post development process; and had been a matter of concern only when s penetrated by attackers. Barry Boehm and Victor R. Basili, famous software experts from University of South California and University of Maryland observed that finding and fixing a software problem after delivery is often 100 times more expensive than finding and fixing it during the requirements and design phase. But now, the need to consider security from the ground up is a fundamental tenet of secure system development. We can reduce the cost and efforts by implementing the security aspect right from beginning i.e. from requirement phase onwards.
