The Framework for Improving Critical Infrastructure Cybersecurity, developed by NIST, is a set of guidelines aimed at helping organizations manage cybersecurity risks effectively. Version 1.1 builds on the original framework by providing new tools and enhancements to address emerging challenges in cybersecurity.

Key improvements in Version 1.1 include:

• Self-Assessment Guidance: Organizations can better evaluate and understand their own cybersecurity risks and practices.
• Focus on Supply Chain Risks: The updated framework emphasizes managing risks posed by third-party partners and vendors.
• Enhanced Identity Management: It includes refined guidelines for securing access to systems and sensitive information.
• Vulnerability Coordination: Encourages transparent communication and swift action to address system weaknesses.
• Clarified Tier Usage: Helps organizations align cybersecurity practices with their goals using the framework’s tiers.

This framework remains voluntary and adaptable, making it suitable for a wide range of users, from small businesses to large corporations. Its purpose is to strengthen the security and resilience of critical systems, like energy, healthcare, and transportation infrastructures, against cyber threats.
