The National Institute of Standards and Technology (NIST) is a United States federal agency that develops and promotes measurement standards, including those for cybersecurity. NIST plays a crucial role in creating guidelines, frameworks, and best practices to help organizations manage and reduce cybersecurity risks. Its publications, such as the NIST Cybersecurity Framework and Special Publications 800 series, are widely adopted by both government and private sectors. NIST is also responsible for standardizing secure cryptographic algorithms, ensuring robust data protection and secure communications. Through its work, NIST helps enhance national security and foster innovation in technology.
