Cybersecurity Standards

Differences Between Frameworks, Standards, and Regulations

In cybersecurity, frameworks, standards, and regulations are often misunderstood or used interchangeably, but they serve distinct purposes:

• Frameworks provide flexible, high-level structures to guide security strategies, blending standards and guidelines (e.g., NIST CSF)
• Standards set specific, measurable requirements for achieving consistent security outcomes (e.g., ISO 27001)
• Regulations enforce mandatory legal compliance to protect data and ensure accountability (e.g., GDPR, HIPAA)

While these terms often overlap, they are not the same. Understanding their differences is critical to aligning your cybersecurity strategy with both best practices and legal requirements. For a detailed explanation, read the article about What is Governance?.

NIST CSF
