When creating an application security program, it can be difficult to make all the resources, policies, procedures, and expectations available to employees. There should be a centralized location for developers, project managers, and auditors to look up application security best practices, the organization's secure development processes, and time lines for remediating vulnerabilities.
The Software Assurance Maturity Model (SAMM) and Building Security In Maturity Model (BSIMM) recommend addressing these needs using an application security portal (See Software Assurance Maturity Model 1.0, EG3 "Create formal application security support portal" and Building Security In Maturity Model, SR1.2 "Create security portal." This centralized internal website or application should be a one-stop shop for all the organization's secure development needs.
So what kind of characteristics should this portal have? Well, employees should be able to easily create and update information on the website. Access controls need to be applied to specific content to ensure only approved guidance, policies, and procedures are included. The portal should also allow collaboration within development groups as well as between development groups. It would also be nice to be able to version documents to see how and when information changes over time.
After reviewing these characteristics, I realized that a Wiki would provide all these features and could easily be placed within an organization's internal network. Specifically, TikiWiki provides collaboration through user pages, forums, blogs, chat, internal messages, and newsletters. It also allows access controls to be applied to individual categories. For example, a "Guidance" category can be created and pages can be grouped within this category. Read only access can be granted to all users, and write access can be granted to specific individuals responsible for updating the organization's guidance documents. A wiki also automatically versions pages so users can see when information is updated and how it changed. Finally, TikiWiki also provides the concept of structures. Structures group pages in a meaningful way allowing easy navigation and well defined organization of information.
