SABSA mapped to O-ISM3

Enterprise Architecture is a very effective approach to understand with detail how the success of an organisation depends on Information Technology. In order to leverage the use of SABSA and TOGAF, The Open Group recently published Combining The Open Group Standards, O-ISM3 and TOGAF®, with the SABSA® Framework

In order to help SABSA and O-ISM3 practitioners use both standard we published this mapping of both standards:

Swiss Armed Forces using O-ISM3

by Lars Minth 29.03.2011

The usage of ISM3 within the Information Assurance program of the Swiss Armed Forces is threefold:

  • first there is the necessity to comply with a couple of regulations inter alia the ISO 27k family, ISO 31000 and ISO 20000.
  • then the development of measurable and achievable security processes is very demanding in such a high security environment while the pure implementation of ISO 27k, especially its controls, is not sufficient to prove a Return of Security Investment (ROSI)
  • at last the governance of security in a highly decentralized organization needs a clever structuring.

Basically in all of these action areas O-ISM3 is giving us a helping hand and therefore saving us time and money to develop an own interpretation of ISO 27k. ISM3 came into the focus of the Swiss Armed Forces during a study about a business-driven implementation of an ISMS in order to regain management attention and acceptance for the restructuring of security. O-ISM3 itself is not a new invention but a straight forward and enabling approach to comprehend existing security frameworks in order to make security understandable for the rest of the (business) world. During the long process of aligning diverse security initiatives within the Swiss Armed Forces ISM3 is and will be the central repository and helping cornucopia to establish security processes which are measurable, acceptable and achievable in the sense of ROSI. The methodology O-ISM3 provides is helping to achieve ROSI while the O-ISM3 security processes in detail are helping to focus on the servicing and main-tenance of security at all levels: operational, tactical and strategic.

Bankia’s experience with O-ISM3

CajaMadrid (now Bankia) started using O-ISM3 in the security process of ethical hacking of systems and applications. Several enhancements were made in order to measure the metrics of this process, and a Service Level Agreement was established based on those metrics. Using O-ISM3 criteria, the classification of information systems, which determines how frequently the systems are tested, was improved.

As a result of O-ISM3 implementation, the team’s productivity doubled during the first year. The follow-up reports with metrics made collaboration between developers, system administrators and security personnel easier and more productive. The information available is so detailed that CajaMadrid now uses objective criteria to give an award to the manager whose applications or systems present the fewest vulnerabilities, and vulnerabilities that are found are fixed faster.

The methodology’s orientation on deliverables makes the entire evidence-generating activity possible, which means that it is auditable, measurable and manageable. As the management system is metrics based, daily operations do not require audits for improvement, speeding up the improvement cycle significantly. When metrics correlate well with pursued goals, process improvement leads directly to the achievement of goals with greater effectiveness, efficiency and quality. Metrics make the status and progress of activities clearly visible, making it easier to reach agreements with our internal client and partners, and communicate our achievements to upper management. Ultimately, this methodology allows information security to be managed using best practices that apply to business in general. Based on the success of the methodology, we are extending the use of the method to other processes.

This is what the CISO had to say: "We are very interested in the method, and once it has been set up, it is simple to use.”

Bankia is ISO27001 and ISO20000 certified, and uses CMMI-3 and standards like ITIL, OSSTMM and many others. O-ISM3 integrates seamlessly with all of them and we have even received a positive note about our ISMS certification thanks to O-ISM3.
