How DoYou StayAhead in Cybersecurity?
There are a good number of components to a network security strategy that enables you to stay ahead of threats, which can be a challenge for organizations of all sizes. Reported global security incidents increased by 69.8% just between February and March of 2024. To protect your organization, it’s important to use a structured approach to cybersecurity. For 2024, NIST (the National Institute of Standards and Technology) has created an updated Cybersecurity Framework (CSF), the NIST CSF 2.0, which provides an industry-agnostic approach to security. It's designed to help companies manage and reduce their digital security risks.
The Core of NIST CSF 2.0
The focus of what CSF 2.0 represents is found in the Core. The Core consists of five concurrent and continuous Functions. These are: Identify, Protect, Detect, Respond, and Recover. These functions provide a high-level strategic view of risks as well as an organization's management of those risks. This allows for a dynamic approach to addressing threats.
1) Identify
Identification of threats is always the first step, so this function involves identifying and understanding the organization's assets, cyber risks, and vulnerabilities. It's essential to have a clear understanding of what you need to protect. You can’t effectively install safeguards until you take stock of the importance of what you’re protecting and what you’re protecting it from.
2) Protect
Once you have identified assets and threats, the protect function focuses on implementing safeguards. These protections are to deter, detect, and mitigate risks, including measures such as firewalls, intrusion detection systems, and data encryption.
3) Detect
The most important way to minimize the potential damage from a threat is through early detection. The detect function emphasizes the importance of detection as well as having mechanisms to identify and report suspicious activity.
4) Respond
You’ve detected the threat, so now what? The response function outlines the steps to take in the event of a security incident. This includes activities such as containment, eradication, recovery, and lessons learned.
Tailoring the Framework: Profiles and Tiers
CSF 2.0’s updated framework introduces the concept of Profiles and Tiers. These help organizations tailor their digital defense practices, customizing them to their specific needs, risk tolerances, and resources.
Profiles
This represents the alignment of the Functions, Categories, and Subcategories into Profiles. They're aligned with the business requirements, risk tolerance, and resources of the organization.
Tiers
Arranging defenses into Tiers provides context on how an organization views digital security risks, as well as the processes in place to manage those risks. They range from Partial (Tier 1) to Adaptive (Tier 4).
How To Get Started with NIST CSF 2.0
There are a few things you can do to get started on a good footing with NIST CSF 2.0.
Get Familiar with the framework: Take the time and read through the NIST CSF 2.0 publication. Familiarize yourself with the Core Functions and categories.
Consider what you’re doing now: Assess your current overall security posture. This will help you identify any gaps or weaknesses.
Develop an overall security plan: Based on your assessment, develop a comprehensive plan. It should outline how you will put in place the NIST CSF 2.0 framework in your organization.
Seek professional help: No, we don’t mean a psychiatrist… If you need help getting started with NIST CSF 2.0? Seek out a Managed IT services partner. We’ll offer guidance and support. If you follow these steps, you can easily begin to deploy NIST CSF 2.0 effectively within your organization. At the same time, you'll be improving your overall comprehensive digital posture.
