Navigating NIST CSF

The National Institute of Standards and Technology (NIST), with its rich history and diverse mission, plays an indispensable role in shaping information security. NIST continues to lead the way in developing and promoting standards, guidelines, and best practices that empower both private and public sectors in cybersecurity.

About the NIST CSF

In 2023, NIST announced the NIST Cybersecurity Framework (CSF) 2.0. The Framework has been used widely to reduce cyber security risks since its initial publication in 2014. While NIST CSF 1.1 remains an effective framework for addressing cyber security risks, there was also widespread agreement among many organizations that changes were warranted to address current and future cyber security challenges and to make it easier for organizations to use the Framework. Thus NIST CFR 2.0 published their initial public draft on August 8, 2023, with comments due by security professionals in November 2023.

The NIST CSF 2.0 provides guidance to industry, government agencies, and other organizations to reduce cyber security risks. It offers a taxonomy of high-level cyber security outcomes that can be used by any organization – regardless of its size, sector, or maturity – to better understand, assess, prioritize, and communicate its cyber security efforts. The Framework does not prescribe how outcomes should be achieved. Rather it maps to resources that provide guidance on practices and controls that could be used to achieve outcomes.

The Updated version of CSF 2.0 is expected to be published in early 2024, showcasing NIST’s commitment to engaging with the cybersecurity community and adapting to evolving digital threats.
In this article, we will discuss the NIST Cybersecurity Framework (CSF), who is required to follow it, and its Implementation levels.

Understanding NIST

The National Institute of Standards and Technology (NIST) is a non-regulatory federal agency within the United States Department of Commerce. It was established in 1901 and has a rich history of promoting innovation and industrial competitiveness in the United States.

At this initial stage, an organization possesses some awareness of the NIST CSF and may have put certain controls in place within select areas of its infrastructure. Cybersecurity actions are often reactive, not pre-planned. Awareness of cybersecurity risks is limited, and the organization may lack the necessary resources and structured processes for effective information security.

Tier 2 – Risk Informed

Moving forward, the organization exhibits a heightened understanding of cybersecurity risks and may share this information informally. However, there is still no well-defined, consistent, and proactive organization-wide process for managing cybersecurity risks.

Tier 3 – Repeatable

At this stage, an organization and its senior leadership are keenly aware of cybersecurity risks. They have successfully established a repeatable and comprehensive organization-wide cybersecurity risk management plan. Additionally, the cybersecurity team has devised a clear action plan for monitoring and responding to cyber threats effectively.

Tier 4 – Adaptive

Organizations reaching this pinnacle of cybersecurity maturity have developed high cyber resilience. They utilize lessons learned and predictive indicators to prevent cyberattacks proactively. The cybersecurity team continuously advances and fine-tunes the organization’s cybersecurity technologies and practices to swiftly adapt to evolving threats.

This approach encompasses an organization-wide commitment to information security risk management, integrating it into budget decisions and fostering a cybersecurity-focused organizational culture.

NIST 800-53

The NIST 800-53 compliance standard titled “Security and Privacy Controls for Federal Information Systems and Organizations” is primarily intended for federal information systems, government agencies, and associated government contractors and departments that work with the government. Compliance with NIST 800-53 is necessary to ensure the security of federal organizations and to ensure that any third-party vendors or organizations they work with have also taken the necessary steps to secure their systems and data.

Following the NIST 800-53 framework is crucial for several reasons.

1. 1. It helps organizations establish a strong foundation of guiding elements, strategies, systems, and controls to support their cybersecurity needs and priorities
   2. NIST 800-53 fosters communication and collaboration between organizations, acting as a common framework that enables different entities to understand and discuss cybersecurity issues cohesively with shared language.
