This is a known issue within the Open Group. Given this, the TOGAF-SABSA Integration project started in May 2010 as a joint initiative of both the Architecture Forum and the Security Forum of The Open Group, and the SABSA Institute.
For the detailed outputs of this project see: “How SABSA and TOGAF complement each other to create better architectures” available on the opengroup.org site.
SABSA and TOGAF are culturally and philosophically very similar, both being business-focused and both having a vision of architecture as an enterprise-wide blueprint. They have different roots and different histories, however, and therefore the actual frameworks are not identical.
However, the biggest differences is that TOGAF is more of a general purpose framework meant to be extended or used as an EA platform to be customized while SABSA is primarily focused on risk management and security architecture as shown below:
Each time a particular link is made, it is possible to dispute it when viewing it from a different angle. Mappings that seem obvious for one person make no sense to the other. No trivial, single mapping exists between TOGAF and SABSA that seems logical to all. Making the integration work requires a degree of “can do” attitude and some rules-of-thumb which avoid lengthy detailed discussions without a logical resolution.
A high-level mapping to the SABSA approach and the TOGAF ADM are shown below:
SABSA Defined
