In the software development life cycle (SDLC), what is the disposal phase?
It's when a system is removed from production
It's the phase that involves debugging
It's when code is scrapped in the middle of the beta testing phase
It's when a need for a new system is defined
It's when a system is removed from production. âThat version of our application is obsolete, update to our latest stable release!â
The disposal phase is not just removing a system from production..... Per NIST Special Publication (SP) 800-64, Revision 2, Security Considerations in the System Development Life Cycle: Disposal Phase. In this phase, plans are developed for discarding system information, hardware, and software and making the transition to a new system. The information, hardware, and software may be moved to another system, archived, discarded, or destroyed. If performed improperly, the disposal phase can result in the unauthorized disclosure of sensitive data. When archiving information, organizations should consider the need for and the methods for future retrieval. Usually, there is no definitive end to a system. Systems normally evolve or transition to the next generation because of changing requirements or improvements in technology. System security plans should continually evolve with the system. Much of the environmental, management, and operational information for the original system should still be relevant and useful when the organization develops the security plan for the follow-on system.
