Announcement

This document describes new and improved practices, tasks, and examples for the secure and reliable development, delivery, and improvement of software.                        

Few software development life cycle (SDLC) models explicitly address software security in detail, so secure software development practices usually need to be added to each SDLC model. SP 800-218 recommends the Secure Software Development Framework (SSDF), which is a core set of high-level secure software development practices that can be integrated into each SDLC implementation.

Following such practices should help software producers reduce the number of vulnerabilities in released software, mitigate the potential impacts of the exploitation of undetected or unaddressed vulnerabilities, and address the root causes of vulnerabilities to prevent future recurrences. Because the framework provides a common vocabulary for secure software development, software acquirers can also use it to foster communications with suppliers in acquisition processes and other management activities.

NOTE: A call for patent claims is included in this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.
