On April 16, 2018, The National Institute of Standards and Technology released an updated version of its Framework for Improving Critical Infrastructure Cybersecurity (Cybersecurity Framework).
The Cybersecurity Framework was first issued in February 2014 and has been widely adopted by critical infrastructure owners and public and private sector organizations to guide their cybersecurity programs. While intended for use by critical infrastructure industries, the flexibility of the framework means it can also be adopted by a wide range of businesses, large and small, including healthcare organizations.
The Cybersecurity Framework incorporates guidelines, standards, and best practices and offers a flexible approach to cybersecurity. There are several ways that the Framework can be used with ample scope for customization. The Framework helps organizations address different threats and vulnerabilities and matches various levels of risk tolerance.
The Framework was intended to be a living document that can be updated and improved over time in response to feedback from users, changing best practices, new threats, and advances in technology. The new version is the first major update to the framework since 2014 and the result of two years of development.
NIST’s Matt Barrett, program manager for the Cybersecurity Framework, explained that the latest version “refines, clarifies and enhances version 1.0.” While several changes have been made in version 1.1, Barrett explained, “It is still flexible to meet an individual organization’s business or mission needs and applies to a wide range of technology environments such as information technology, industrial control systems and the Internet of Things.”
Version 1.1 of the Cybersecurity Framework includes several updates in response to comments and feedback received in 2016 and 2017 from organizations that have already adopted the Framework.
Version 1.1 sees refinements to the guidelines on authentication, authorization and identity proofing and a better explanation of the relationship between implementation tiers and profiles. The Framework for Cyber Supply Chain Risk Management has been significantly expanded and there is a new section on self-assessment of cybersecurity risk. The section on disclosure of vulnerabilities as also been expanded with a new subcategory added related to the vulnerability disclosure lifecycle.
“Cybersecurity is critical for national and economic security,” said Secretary of Commerce Wilbur Ross. “The voluntary NIST Cybersecurity Framework should be every company’s first line of defense. Adopting version 1.1 is a must do for all CEO’s.”
NIST is also planning to release a companion ‘Roadmap for Improving Critical Infrastructure Cybersecurity’ later this year and will be hosting a webinar later this month to explain and discuss the version 1.1 updates to the Framework.
