Abstract

Sometimes security and technology professionals confuse their state of compliance with their security posture. While an organization can meet the requirements to any regulatory standard (HIPAA, SOC, etc.), doing so should not be construed as meeting the requirements to defend a potential cyberattack, provide data protection during business processing, or maintain a highly secure development environment. In this chapter, the authors discuss how security and compliance can co-exist. They associate each one of these with controls that are either derived from formal frameworks or meet custom operational or other requirements of an organization. They explore how each control needs to be implemented with a risk perspective in mind, and finally, they suggest methods on how to manage such a control catalog.

Why Compliant Does Not Mean Secure

Compliance guidelines are provided as a generalized method to define common minimum standards for a specific area of concern such as payment industry, healthcare, financial information and so on. Given the high degree of interpretation that each guideline is subject to, any blind strict adherence will not result in any material improvements in security or operations. There are many factors that can still cause a security failure despite an organization's adherence to the standard. Lack of skilled staff, human error, availability of information to support breach detection, dysfunctional organizational structures are all contributors to bad security despite meeting the compliance standards.

Establishing a framework is a very complicated undertaking. As Table 1 suggests, most frameworks are updated in regular intervals, yet keeping up with the pace and implementation of certain updates can be challenging.
