[This is the sixth part of a seven-part series on transforming security during this economic downturn based on the thesis that what is needed today is adaptable security that both leverages existing investments and addresses the fact that the demands of the business will increasingly be a moving target. Part 5 described 4 steps to establish services-based security. This part address the flexibility needed to balance these security services with business needs and strategic changes, and introduces an adaptable Security Services Model.
Comments on this post and the series are welcome!]
Maintaining security is important, but it also demands flexibility and accepting that not all security practices are necessary or possible. As stated previously, the all-or-nothing approach to security must be replaced with a best-impact approach to security in an environment of business needs and strategic changes.
Information security experts understand the term “compensating controls” very well. The ability to accomplish the desired level of security indirectly is commonplace. This fundamental practice needs to become the underlying force for the balancing of security services. As services are defined and implemented they will have specific criteria determining scope, depth, method, and results. By design there will be areas where there may be less security being implemented than under normal conditions. Over time, security services will allow for greater adaptability (see figure), ushering in the ability to dynamically apply compensating controls far more rapidly and address more accurately current business demands.

Adjusting Security Services Model
For some, when security is not applied to a particular level the business unit is typically asked to sign-off on risk acceptance. As stated earlier, risk appetite during difficult economic times is increased and if organizations are not mindful, security groups will be reduced to processing risk acceptance forms and not implementing much needed security.
When armed with a risk assessment and tracking model that reflects business and security risk, a security services framework and an underlying governance model to communicate action effectively to the business, inter-service adjustments can be made to provide for compensating controls.
For example, assume you have three security services, each focused on performing specific tasks for various business units. By definition, not all services are applied equally to all conditions and therefore each service needs to be balanced relative to risk and mission. Through a detailed analysis and consistent views from a risk perspective, undesirable conditions may surface.
In my next post on this topic (Part 7), I’ll conclude with the importance of a services relationship model to bring it all together.
