The National Institute of Standards and Technology Cybersecurity Framework 1.1 explained
The Cybersecurity Framework was first published in 2014 by the National Institute of Technology. It was developed with input from research institutes, industry, and government. Originally, it was created to standardize cybersecurity within organizations dealing with critical infrastructure. It has since been adopted by organizations across a range of industries. Popular because of its flexibility, organizations of all sizes can customize and use the framework to meet their specific cybersecurity needs. It can be used to understand the critical elements of an organization's service delivery, making cybersecurity planning cost-effective. NIST Cybersecurity Framework version 1.1 was released in April 2018. It makes a range of improvements to the original version, based on workshops, public feedback and consultation. Changes include new guidance on self-assessment of cybersecurity risks, and an expanded section on Cyber Supply Chain Risk Management. Updates reflect advances in wider technology and cybersecurity threats.The Benefits of the NIST Cybersecurity Framework
The NIST Cybersecurity Framework brings a range of benefits to all organizations. Security breaches and cyber threats can have a huge financial impact, alongside the impact made on reputation. The framework can help organizations prevent, resolve and recover from serious cybersecurity incidents. The NIST Cybersecurity Framework helps organizations:- Improve and support existing IT risk management plans.
- Embed clear guidelines to prevent and resolve cybersecurity incidents.
- Prepare for restoring normal operation after serious cybersecurity breaches.
- Create a cybersecurity risk management process tailored to the organization's needs.
- Encourage a systematic approach to cybersecurity.
What's in the NIST Cybersecurity Framework?
The NIST Cybersecurity Framework is made up of three components:Component 1: Core
The core component contains activities and objectives to improve cybersecurity risk management. This component contains the important Five Functions of the framework.
Component 2: Tiers
The tiers component helps define the level of cybersecurity risk management required. This allows for a scaled approach to suit different budgets and organizations.
Component 3: Profiles
The profiles component helps to identify cybersecurity risks and objectives in the organization and wider sector.
The Five Functions of the NIST Cybersecurity Framework
A vital part of the NIST Cybersecurity Framework is the Five Functions found within the core component. Each function represents an important step in cybersecurity risk management and contains an array of categories and subcategories. The Five Functions are:Function 1: Identify
Identify the cybersecurity risks to all areas of the organization including resources, data and people. This helps to inform the risk management strategy.
Function 2: Protect
The steps needed to safeguard services against cybersecurity threats, limiting serious incidents and breaches.
Function 3: Detect
Outlines the process for identifying the existence of a cybersecurity incident and its impact.
Function 4: Respond
The process for responding to a cybersecurity incident, mitigating its impact on the organization.
Function 5: Recover
The steps to restoring service after a cybersecurity incident.
