Security is the main concern now-a-days for any software system. In the past security was often treated as an add-on on other requirements, which make the system expensive on both the developer and user sides.

Security engineering should be integrated with the Software development life cycle to handle all the issue related to the software security. There are various techniques for addressing security requirements during the early phases of Software Development Life Cycle (SDLC).
