A brief video introduction to the NIST framework
NIST is the National Institute of Standards and Technology. They were selected for the task of developing the NIST Cyber Security Framework (CSF) because they are a non-regulatory federal agency. They act as an unbiased source of scientific data and practices, including cybersecurity practices.
The framework was the result of a US executive order in 2013. By 2014 it was adopted globally, partly due to global organisations having a U.S. Headquarters and being U.S. owned organisations such as Google, Amazon/AWS, Paypal and Morgan Stanley.
