When dealing with the cyber security of your organization you have to evaluate your legal environment. Are there regulations put into place that can help regulate and maintain a safe and secure work environment? Is there a set policy framework for computer security guidance that will help me assess our cyber security readiness?
In 2014, the version 1.0 of the NIST Cybersecurity Framework (NIST CSF) was published by the US National Institute of Standards and Technology. NIST CSF helps shift organizations to be more proactive about risk management, especially with the continued popularity in internet usage. According to a survey "Trends in Security Framework Adoption". 70% of organizations view NIST's framework as a security best practice. But what exactly does it entail?
The NIST CSF organizes material into five different "functions" which can be placed within 22 different "categories". Each category defines a number of subcategories of outcomes and security controls, which total up 98. Below we've listed the five functions of the NIST CSF framework and their categories.
