NIST Cybersecurity Framework

Introduction

Gone are the days when businesses only had to think about bringing in revenue. While growth is always welcomed, businesses also need to focus on reducing disruptions. From systems downtime to loss of critical data, cybersecurity breaches not only interrupt usual operations, but also impact brand reputation and customer trust in the long run. Developed by the National Institute of Standards and Technology, the NIST Cybersecurity Framework is now widely regarded as the gold standard for cybersecurity posture. When used along risk assessments, cost-benefit analyses, and continuous monitoring, NIST offers the tools for companies to prevent unexpected business interruptions and mitigate financial losses.

Overview of NIST Cybersecurity tools

Studies show that 65% of consumers lose trust in a company after a data breach, and stock prices can drop by about 5% the day a breach is disclosed. It takes years or even decades of work to build social credibility for a business, and all that can be wiped away in just a few days.

The interconnectedness of today's business ecosystem proves that cybersecurity efforts shouldn't be limited to the work of a single department. The NIST cybersecurity framework is particularly useful for bridging the gap between technical and business stakeholders. As a common language and methodology for discussing cybersecurity risks and strategies, the framework allows for better communication, decision-making, and alignment with broader business objectives. This feature sets it apart from other frameworks that may focus solely on technical aspects. Plus, the framework's flexibility and adaptability is attractive to organizations of all sizes. This allows companies to tailor their cybersecurity programs for their specific needs while staying aligned with regulatory requirements.

Pillars of NIST

Let's start with the pillars of NIST CSF, as they provide the backbone that guides how an organization ultimately chooses to design and implement its cybersecurity program. Currently, the framework is made of six key function areas: Govern, Identify, Protect, Detect, Respond, and Recover.

• In the "Govern" function area, the objective is to establish and maintain governance for effective cybersecurity risk management. The goal is to define clear roles, aligned objectives, and robust risk strategies.
• The focus of the "Identify" function is to understand risks to critical assets and to prioritize vulnerabilities and threats for informed risk decisions.
• "Protect" involves developing safeguards to secure systems and data integrity, with the goal to enhance overall security posture.
• "Detect" aims to promptly identify cybersecurity events through monitoring processes. This should then allow for swift incident detection.
• "Respond" involves developing response plans to contain and mitigate cyber incidents effectively. The goal here is timely and efficient responses.
• Lastly, the "Recover" function focuses on recovery plans to restore capabilities post-incident. In the unfortunate cases when cyberattacks did occur, a solid recovery plan enables quick system and service restoration for business continuity.

With ever more sophisticated cyberattacks, the NIST CSF will likely be updated with time. Version 2.0 was released this February to expand its scope to all organizations, not just those in critical sectors. Note that one of the six main pillars we mentioned earlier, Govern, was a new addition in the latest iteration. This emphasizes the role of governance and enterprise-level support when it comes to cybersecurity programs.

Questions and answers

View answer

The strategic importance of cybersecurity investments significantly impacts the overall business success of companies like Tesla and Nvidia. These companies operate in sectors where data security and integrity are paramount. Cybersecurity investments help protect their intellectual property, customer data, and operational systems from cyber threats. A robust cybersecurity framework can prevent disruptions, maintain customer trust, and protect the brand reputation. Furthermore, it can also provide a competitive advantage in the market. Therefore, cybersecurity is not just a defensive measure but also a strategic initiative that can contribute to the business growth and sustainability.

What are some alternative strategies to the NIST Cybersecurity Framework that other organizations might use?

View answer

There are several alternative strategies to the NIST Cybersecurity Framework that organizations can use. These include the ISO 27001, which is an international standard for information security management systems, and the CIS Critical Security Controls, which is a prioritized set of actions to protect organizations and data from known cyber attack vectors. Other alternatives include the COBIT (Control Objectives for Information and Related Technologies) framework, which helps organizations meet their information needs, and the PCI DSS (Payment Card Industry Data Security Standard), which is a set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment.

Cost Benefit Analysis

In June 2017, the world saw the most devastating cyberattack in history. The NotPetya attack left significant marks on numerous multinational companies and profoundly disrupted the global supply chain with its rapid spread through interconnected networks. The total damages from the attack exceeded $10 billion. That number alone just wiped out years of business growth. In 2020, attacks cost governments and businesses $1 trillion, which equals to about 1% of global GDP. For individual companies, the average cost of a single data breach was $3.6 million.

While cybersecurity programs aren't traditionally viewed as explicitly "revenue-generating", they sure do prevent revenue loss, in millions and billions. Sure, cybersecurity measures can seem costly to implement, so here is where cost-benefit analysis comes in.

The right cybersecurity spending can minimize risks associated with revenue, reputation, and legal fees, while also generating indirect benefits like better compliance alignment and increased productivity. By comparing the costs of prevention with potential losses from cyberattacks, organizations can determine the most effective way to deliver the desired outcomes while managing risks within their unique business context. Ultimately, the best approach finds balance between enough investments to achieve protection without overspending or underinvesting.

Monitoring

Ongoing monitoring is an unskippable step when it comes to understanding the overall effectiveness of cybersecurity measures. These dashboards provide a visual representation of key security metrics to identify trends, anomalies, and areas that require attention.

One way to organize this information is by categorizing performance based on the six pillars of NIST. for example, this dashboard shows the "Identify" and "Protect" pillars and breaks down each subtask into "performed", "incompletely performed", and "not performed". Alternatively, a dashboard of gauge charts can track NIST compliance areas over time. On a more granular level and for team members with more technical roles, uptime/downtime monitoring allows any anomalies to be detected promptly before they lead to graver consequences.
