 The OSSA programme is listed in the Singapore-based Infocomm Competency Management System which is a government-maintained public database of information technology-related courses.The OSSA programme does not focus on hackers' software as these quickly become obsolete as software patches are released.It first looks at security from a methodological perspective and draws lessons from Sun Tzu's "The Art of War" to generate a security framework and then populate it with resources and tools by which the various security aims and objectives, such as "how to defend your server against a hacker's attacks" can be met.
