Every business, every organization, across the United States and globally, regardless of vertical industries, is faced with two executive-level challenges:
- Compliance with state and federal (national) regulatory compliance mandates
- Establishing a credible cyber defense to reduce disruptive risks to business
This article describes how the HITRUST CSF delivers a prescriptive cybersecurity standard.
HITRUST CSF Prescriptions Across Domains
The HITRUST CSF is a prescriptive framework. It is a credible framework for organizations to establish a mature cybersecurity and compliance program. The HITRUST CSF provides a comprehensive, scalable, and a technology-neutral framework to address HIPAA mandates.
HITRUST CSF is prescriptive – it is very specific on the minimal capabilities organizations must implement continually to address mandates such as HIPAA, and manage their cybersecurity program.
In Figure 1 we examine a sampling of some key prescriptive requirements from HITRUST CSF. Note that Figure 1 is a sampling only, and not a complete list of all prescriptive requirements.

HITRUST CSF is a formal and formidable framework, developed specifically for the healthcare industry, to address privacy and security regulatory requirements.
Closing Remarks for Senior Executives
Probably, the most important strategic security decision that the organization can make is the framework that the organization adopts for its cybersecurity and compliance program.
The bottom-line for senior executives is to select a framework that is robust, scalable, and mature. The HITRUST CSF is all that, and prescriptive in its requirements. This is important so the enterprise cybersecurity program can be actively measured and monitored on a continual basis.
