In the cybersecurity industry, the NIST Cybersecurity Framework (CSF) 2.0 is an update to the original framework developed by the National Institute of Standards and Technology (NIST).
It is intended to assist enterprises in managing and mitigating cybersecurity risks. Moreover, the NIST Cybersecurity Framework (NIST CSF) is a customizable set of standards and best practices meant to assist organizations in improving their information security and managing cybersecurity risks.
Moving further, its core functions, developed as a public-private sector collaboration led by NIST under a presidential executive order to improve critical infrastructure cybersecurity, quickly expanded beyond high-level energy and critical infrastructure; its outcomes-based approach allowed it to apply to almost any sector and business size. This framework profile includes the Framework Core, Profiles, and NIST Implementation Tiers and how they affect a business’s cybersecurity strategy.
Here, we’ll look at the fundamentals of the framework and how its functions enhance cybersecurity.
1. Identify and develop organizational understanding
The first function of the framework, NIST CSF 2.0, defines the Identify function as “developing the organizational understanding to manage cybersecurity risk to systems, assets, data, and capabilities.” The focus is on the business and its related cybersecurity risk, especially given the available resources. This function, for example, has the following outcome categories:
- Asset Management
- Business Environment
- Governance
- Risk Assessment
- Risk Management Strategy
The NIST Identify function establishes the foundation for your organization’s cybersecurity initiatives. Determining which environments exist, what risks they provide, and how they relate to your business goals is critical to the Framework’s success.
The successful application of the Identify function leads businesses to understand all assets and environments within the enterprise, identify the existing and intended states of controls to protect those assets, and plan the transition from current to desired states of security.
2. Protect infrastructure service delivery
Overall, NIST claims that the framework’s key functions help an organization express its cybersecurity risk management by organizing information, sharing sensitive information, enabling cybersecurity risk management decisions, addressing threats, and improving through learning from previous activities.
The Framework Core’s Protect function is vital because it seeks to establish and apply necessary protections to assure critical infrastructure service delivery. Besides, this further facilitates the capacity to mitigate or contain the impact of a potential cybersecurity event. NIST defines result Categories for this Function as Identity Management and Access Control, Awareness and Training, Data Security, Information Security Protection Processes and Procedures, Maintenance, and Protective Technology.
Protect is when the Framework becomes more proactive, as opposed to Identify, which focuses mostly on baselines and monitoring. The Protect function includes access control, awareness, and training categories. These categories, together with the Protect function, are manifested in two- and multi-factor authentication techniques to manage access to assets and environments, as well as employee training to reduce the risk of accidents and socially engineered breaches.
3. Detect cybersecurity events
The Detect function necessitates the formulation and implementation of appropriate operations to detect the presence of a cybersecurity event.
The Detect function enables prompt detection of cybersecurity events. This Function’s output categories include anomalies and events, continuous security monitoring, and detection processes. Also, it is an essential step toward a solid cyber program. The sooner a cyber incident is recognized, the faster its consequences can be addressed.
Examples of completing steps towards a certain Detect function:
- Anomalies and Events: Train your team to collect and evaluate data from numerous sources to spot a cybersecurity event.
- Security and Continuous Monitoring: Have your team watch your assets 24/7, or consider employing an MSS to complement.
- Detection Processes: Try to learn about a breach as soon as feasible and comply with disclosure obligations as appropriate. Your program should be able to detect any unauthorized access to your data as soon as feasible.
4. Respond to detected cybersecurity incidents
According to NIST, the Respond function is responsible for developing and implementing appropriate activities to take action regarding a detected cybersecurity incident.
The Respond Function can enhance the ability to mitigate the consequences of a prospective cybersecurity attack. Response Planning, Communications, Analysis, Mitigation, and Improvements are some of the result categories within this Function.
Additionally, the Respond function conducts response planning, analysis, and mitigation operations to ensure the cybersecurity program is constantly improving.
Starting with an incident response plan is a critical first step in implementing the Respond function, as it ensures compliance with mandatory reporting criteria that are encrypted and transferred securely for a specific location and industry. A mitigation strategy is an important next step; what steps will your team take to address identified program and organizational risks?
5. Recover/restore impaired capabilities
The Framework Core then determines each function’s underlying key categories and subcategories. It compares them to Informative References, such as current standards, recommendations, and practices for each subcategory (NIST).
According to the NIST framework, recovery is described as “developing and implementing appropriate activities to maintain resilience plans and restore any impaired capabilities or services due to a cybersecurity event.”
The Recover Function enables a fast return to normal activities to mitigate the impact of a cybersecurity occurrence. The core function of this framework is to produce outcomes such as recovery planning, improvements, and communications.
NIST CSF Recovery includes the following areas:
- Recovery Planning: Recovery procedures are evaluated, run, and maintained so that your software can lessen the impacts of an incident earlier rather than later.
- Improvement: Recovery planning and processes are improved as events occur, opportunities for improvement are recognized, and solutions are put in place.
- Communication: Coordinate internally and externally for better organization, planning, and execution.
The Recover function is critical not just in the eyes of the business and security teams but also for clients and the market. Swift recovery with grace and tact puts firms in a better internal and external position than they would otherwise be.
In the end!
Cybersecurity based on the NIST Cybersecurity Framework might take a lot of work. Regardless of how difficult it may be, it will be beneficial. Because the Framework is based on outcomes rather than specific controls, companies may build on a solid basis and supplement them to ensure compliance with new rules as they arise.
