What is NIST ?
NIST is the National Institute of Standards and Technology. It is a non-regulatory agency of the United States Department of Commerce that focuses on promoting innovation and industrial competitiveness. NIST works to advance measurement science, standards, and technology in ways that enhance economic security and improve our quality of life. The agency provides technical leadership and support for the nation’s measurement and standards infrastructure, and it conducts research and develops standards and guidelines in a wide range of fields, including cybersecurity, biotechnology, information technology, and manufacturing.
What is the NIST cyber security framework
The NIST Cybersecurity Framework is a framework developed by the National Institute of Standards and Technology (NIST) to help organizations manage their cybersecurity risks. The framework provides a set of guidelines and best practices for protecting an organization’s critical infrastructure and sensitive information from cyber threats. It is designed to be flexible and scalable, so organizations can tailor it to their specific needs and risk profile. The framework consists of five core functions: identify, protect, detect, respond, and recover. Each function is supported by a set of specific categories and subcategories that provide more detailed guidance on how to implement the framework in practice. The framework is voluntary and is intended to be used by organizations of all sizes and in all industries. It is not a regulatory requirement, but many organizations use it as a basis for their cybersecurity programs.
The five Framework Core Functions are defined below.
• Identify – Develop an organizational understanding to manage cybersecurity risk to systems, people, assets, data, and capabilities.
The activities in the Identify Function are foundational for effective use of the Framework. Understanding the business context, the resources that support critical functions, and the related cybersecurity risks enables an organization to focus and prioritize its efforts, consistent with its risk management strategy and business needs. Examples of outcome Categories within this Function include: Asset Management; Business Environment; Governance; Risk Assessment; and Risk Management Strategy.
• Protect – Develop and implement appropriate safeguards to ensure delivery of critical services.
The Protect Function supports the ability to limit or contain the impact of a potential cybersecurity event. Examples of outcome Categories within this Function include: Identity Management and Access Control; Awareness and Training; Data Security; Information Protection Processes and Procedures; Maintenance; and Protective Technology.
• Detect – Develop and implement appropriate activities to identify the occurrence of a cybersecurity event.
The Detect Function enables timely discovery of cybersecurity events. Examples of outcome Categories within this Function include: Anomalies and Events; Security Continuous Monitoring; and Detection Processes.
• Respond – Develop and implement appropriate activities to take action regarding a detected cybersecurity incident.
The Respond Function supports the ability to contain the impact of a potential cybersecurity incident. Examples of outcome Categories within this Function include: Response Planning; Communications; Analysis; Mitigation; and Improvements.
• Recover – Develop and implement appropriate activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cybersecurity incident.
The Recover Function supports timely recovery to normal operations to reduce the impact from a cybersecurity incident. Examples of outcome Categories within this Function include: Recovery Planning; Improvements; and Communications.

What is ISO 27001?
ISO 27001 is an international standard that outlines the requirements for an information security management system (ISMS). It is a framework that helps organizations to manage and protect their sensitive information, such as financial data, intellectual property, and personal information. The standard provides a set of best practices and guidelines for implementing and maintaining an effective ISMS, and it is designed to help organizations of all sizes and industries to protect their information from unauthorized access, use, disclosure, disruption, modification, or destruction.
What are the differences between NIST & ISO 27001 ?
The NIST Cybersecurity Framework and ISO 27001 are both frameworks for managing and protecting sensitive information, but they have some key differences.
The NIST Cybersecurity Framework is voluntary and is not a regulatory requirement. In contrast, ISO 27001 is an international standard that outlines the requirements for an information security management system (ISMS). It is a more comprehensive and prescriptive framework than the NIST Cybersecurity Framework, and it is designed to help organizations of all sizes and industries to protect their information from unauthorized access, use, disclosure, disruption, modification, or destruction.
To comply with ISO 27001, organizations must have an ISMS in place that meets all of the requirements specified in the standard. In contrast, the NIST Cybersecurity Framework is more flexible and can be tailored to the specific needs and risk profile of each organization. Additionally, while the NIST Cybersecurity Framework focuses specifically on cybersecurity, ISO 27001 has a broader scope and covers all aspects of information security.
