This blog will look closely at NIST vs ISO 27001 (the most recent addition to the ISO series) and help you determine which compliance framework best suits your business needs.

Whether you're a small business owner or an enterprise-level corporation, understanding the differences between these frameworks can help you decide to safeguard your organization against potential cyber threats and data breaches.

NIST Cybersecurity Framework: An Overview

The Cybersecurity Framework (CSF) was developed by the National Institute of Standards and Technology (NIST) in 2013.

It's been used for everything from nanotechnology to cybersecurity ever since, and it's a key resource for companies seeking to develop or improve their cybersecurity frameworks.

The NIST CSF is focused on 5 key areas:

NIST
  • Identify
  • Protect
  • Detect
  • Respond
  • Recover

The NIST Cybersecurity Framework is organized in a hierarchical fashion that allows organizations to begin with the lowest level of protection possible and then move up as needs change over time.

In addition to providing a path for organizations to improve their security posture, the NIST Cybersecurity Framework also offers resources that can be used by individual employees to help them understand how they can take steps toward greater security on their own time.

How NIST CSF Is Used

There are three major components to the system:  

NIST

1) Framework Core:

This is the baseline of the NIST CSF and what everything else is built on. The five functions that make up this core mentioned previously ( Identify, Protect, Detect, Respond, and Recover) are used to identify and manage any risk management issues. The five core functions of cybersecurity contain 23 categories that provide the basic elements needed to establish a solid defensive strategy.

2) Implementation Tiers:

NIST CSF Tier levels provide benchmarks for organizations' cybersecurity efforts, with the highest tier (4) representing a strong adherence to the framework's rules and recommendations.

The four implementation tiers are:

  • Tier 1: Partial
  • Tier 2: Risk Informed
  • Tier 3: Repeatable
  • Tier 4: Adaptive

3) Profiles:

A profile at each tier allows you to gauge your current level of risk and see how improving your security measures can increase protection for everyone on the network.

When you have analyzed these three components, you can better understand the risk level of your system and identify any underlying problems. As such, you will be able to prioritize any issues and take action sooner rather than later.

Now, before we get into NIST Cybersecurity Framework vs  ISO 27001, here's a brief introduction to ISO 27001, so that you can better understand why it’s important for businesses looking to protect their data.

ISO 27001: An Overview

The ISO is an independent international body based in Geneva, Switzerland. It provides standards on a wide range of topics—including information security—to governments and businesses around the world.

First released in 2005, the 27000 standards are a family of corporate guidelines for information technology and security risk management.

ISO 27001 (aka ISO/IEC 27001:2013) is an information security risk management standard that specifies requirements for a comprehensive ISMS.

The basic goal of ISO 27001 protect your company and customer information with:

  • Confidentiality: Only authorized persons may access data.
  • Integrity: Only authorized individuals can modify the data.
  • Availability: The information must be retrievable by authorized persons whenever they need it.

ISO 27001 is a process standard that outlines the steps needed to develop and maintain an ISMS. However, it doesn't include specific language on performing these tasks; you need other resources like the NIST SP 800-30 for guidance on how exactly do them (but not included in ISO 27001).

How ISO 27001 Is Used

So how does ISO 27001 work?

The standards here are meant to help businesses systemize their cybersecurity, growing a system that was put into place to cover certain issues into a full IT management system. You can get certification for compliance with ISO 27001, whether that's through the ISO themselves or a third-party auditor.

With ISO 27001, the scope can be limited to just one aspect of the company, rather than the company as a whole. For example, you could get certified just for your data center, or just for your cloud-based data storage—or any other aspect of your information technology (IT) systems.

When getting certified, you'll have to go through two stages:

Stage 1: Documentation review: Where your documents on processes, policies, and procedures will be audited. They will be looked at to ensure that they meet ISO standards.

Stage 2:  Certification Audit: This will involve an auditor doing a full and thorough on-site assessment to ensure that your systems comply with ISO 27001 fully.

ISO 27001 vs. NIST CSF: Key Differences

Now that you know the basics of NIST CSF and ISO 27001, if you want to improve and certify your cybersecurity systems, which one should you follow? Both of them are highly useful, and it just depends on what you need from them as a company.

Here are some of the key differences between them:

Risk maturity

The age and sophistication of your business's security system will help you decide here.

If you're just getting started with a comprehensive security program, then the NIST Cybersecurity Framework is likely to be a better fit for your organization.

For those that have a more mature system in place and need certification, ISO 27001 is going to be the way to go. This is because it's better at helping businesses mitigate issues such as data breaches.

Certification

For a cybersecurity system to be certified, it must conform with the ISO 27001 framework.

It's a valuable investment to hire an experienced risk management CPA for ISO 27001 audit, obtain your compliance certification and show stakeholders that you're taking cybersecurity seriously. NIST CSF is not a certification—it sets standards but doesn’t certify organizations against them.

Cost

ISO 27001 is a more advanced standard, so it charges for its documentation and other materials. NIST can provide you with good starting points for implementing an information security system and will be free of charge.


ISO 27001 vs NIST CSF: Similarities

Both ISO 27001 and NIST CSF are security frameworks that help organizations identify and mitigate risks. They are similar in that they both have the following elements:

Risk assessment

• Risk treatment plan

• Corrective actions for non-conformities discovered during risk assessments

• Continuous improvement processes

Both frameworks also require organizations to have a documented security policy, which is one of the first steps in implementing both standards. Additionally, both frameworks require that organizations develop a Security Awareness Training Program (SATP) to educate employees on their roles in information security.

Can NIST CSF and ISO 27001 be Used Together?

Although you may want to choose one or the other when it comes to frameworks, sometimes combining them can be a good idea. The trick is figuring out why you'd want do that in your particular case.

A lot of new companies begin with NIST, as it allows them to get up and running without incurring any costs. However, they should consider ISO 27001—it's an international standard that's widely recognized by businesses across the world.

If they decide to move on to ISO 27001 compliance, certification will be much easier as they'll have done most of the work during NIST CSF implementation.

While there are advantages to implementing either of these two solutions, you can also benefit by using them in combination. You'll need to evaluate your options carefully so that you get the best possible security for your business needs.
