25 SANS

The initiative was initiated by the National Security Agency with financial support from the National Cyber Security Division of DHS. It was implemented by MITRE and SANS (SysAdmin, Audit, Network, Security).

According to the information submitted, the parties were able to reach agreement on the top 25 fairly quickly. The second step would be to teach programmers how to write code that is free of the programming errors of the top 25.

The long-term goal is,

• Offer software buyers safer software. For this certification mechanisms are in demand.
• To give programmers tools to check the security aspects of the developed software. To this end, various providers of test software have announced in parallel with the announcement that their software tests code for top 25 programming errors.
• Training providers and developers who train programmers to provide a foundation for training that helps avoid the top 25 bugs.
• Provide employers or contractors with the Top 25 list as an additional reference to help them review applicants' skills.
