* Security Auditor (2 days/yr)<br />
* Business Owner (1 days/yr)<br />
* Managers (1 day/yr)<br />
* Architects (1 day/yr)<br />

==Activities==<br />
===A. Derive security requirements from business functionality===<br />
Conduct a review of functional requirements that specify the business logic and overall behavior for each software project. After gathering requirements for a project, conduct an assessment to derive relevant security requirements. Even if software is being built by a third-party, these requirements, once identified, should be included with functional requirements delivered to vendors.<br />
<br />
For each functional requirement, a security auditor should lead stakeholders through the process of explicitly noting any expectations with regard to security. Typically, questions to clarify for each requirement include expectations for data security, access control, transaction integrity, criticality of business function, separation of duties, uptime, etc.<br />
<br />
It is important to ensure that all security requirements follow the same principles for writing good requirements in general. Specifically, they should be specific, measurable, and reasonable.<br />
<br />
Conduct this process for all new requirements on active projects. For existing features, it is recommended to conduct the same process as a gap analysis to fuel future refactoring for security.<br />
<br />
===B. Evaluate security and compliance guidance for requirements===<br />
Determine industry best-practices that project teams should treat as requirements. These can be chosen from publicly available guidelines, internal or external guidelines/standards/policies, or established compliance requirements.<br />
<br />
It is important to not attempt to bring in too many best-practice requirements into each development iteration since there is a time trade-off with design and implementation. The recommended approach is to slowly add best-practices over successive development cycles to bolster the software’s overall assurance profile over time.<br />
<br />
For existing systems, refactoring for security best practices can be a complex undertaking. Where possible, add security requirements opportunistically when adding new features. At a minimum, conducting the analysis to identify applicable best practices should be done to help fuel future planning efforts.<br />
<br />
This review should be performed by a security auditor with input from business stakeholders. Senior developers, architects, and other technical stakeholders should also be involved to bring design and implementation-specific knowledge into the decision process. <br />
