NIST Cybersecurity Framework: Learn the basics

NIST Cybersecurity Framework: Learn the basics

If you want to improve and organize your cybersecurity program, the NIST cybersecurity framework is an excellent resource to look at. It's a collection of rules and recommendations for bolstering a company's cybersecurity online. The framework proposes a collection of suggestions and standards that help businesses be more ready to spot and stop cyberattacks and instructions for avoiding and recovering from such attacks.

This framework, developed by the National Institute of Standards and Technology (NIST), aims to standardize cybersecurity by providing a consistent set of rules, principles, and standards that can be used by businesses of all sizes and in all sectors. The National Institute of Standards and Technology (NIST) Cybersecurity Framework (NIST CSF) is generally accepted as the model by which all other cybersecurity initiatives should be measured. The framework may be used as a top-level security management tool that aids in assessing cybersecurity risk throughout the business, whether you are just starting to build a cybersecurity program or are currently operating a pretty mature one.

What’s the NIST Cybersecurity Framework and how does it work?

The National Institute of Standards and Technology (NIST) has released a framework to help standardize the cybersecurity industry. Businesses take vastly different approaches when protecting themselves against cybercriminals like hackers, data pirates, and ransomware.

As cyberattacks grow in frequency and sophistication, the challenge of countering them also rises. The fact that companies don't have a coherent plan makes the problem worse.

Another issue that arises from the wide variety of cybersecurity rules, standards, best practices, and technology is that companies can’t easily exchange information regarding attacks. Talking to a coworker at another firm who has gone through a similar assault might be helpful if your business is the target of a hacking effort.

All of this is precisely what the NIST Cybersecurity Framework intends to eradicate. Sharing data across firms and getting everyone on the same page is simplified by a standardized set of rules, norms, and standards.

Which are the NIST Cybersecurity Framework's 5 essential features?

Identify: The Identify process aims to provide a solid foundation for the rest of the cybersecurity initiative. Organizational knowledge of cybersecurity risk to systems, people, assets, data, and capabilities is aided by this role. Understanding the business context, the resources that support essential operations, and the accompanying cybersecurity threats are emphasized in this function to allow an organization to concentrate and prioritize its activities in a way that is compatible with its risk management strategy and business requirements. What follows is a list of the most important things to do in this category:

  • To provide the groundwork for an asset management strategy, it is necessary to catalog all of a company's hardware and software resources.

  • It understands the company's supply network and business climate.

  • They are determining what existing cybersecurity rules will be used to design the governance program and what legal and regulatory obligations there are for the organization's current cybersecurity posture.

  • Assessing risk entails identifying its origins, which may be either internal or external to the company, along with the measures taken to deal with such threats.

  • Constructing a plan for handling potential dangers, including determining how much you are willing to take on.

  • It establishes a framework for controlling supply chain risks, including priorities, restrictions, risk tolerances, and underlying assumptions.

Protect: The Protect feature facilitates the capability to restrict or control the effect of a possible cybersecurity incident by outlining necessary protections to assure delivery of vital infrastructure services. The following are among the most critical tasks performed by this team:

  • Establishing safeguards for all types of company access, whether on-premises or remotely, via identity management and access control.

  • Educating employees on security measures, such as role-based and privileged user instruction, may help them feel more confident.

  • Implementing methods and procedures to maintain and manage the safeguards of information systems and assets, establishing data security protection along with the organization's risk strategy to secure the confidentiality, integrity, and availability of information.

  • Maintenance, incredibly remote maintenance, protects organizational resources. Controlling IT to ensure systems are safe and reliable by company regulations and pacts.

Detect: Identifying the occurrence of a cybersecurity event as soon as possible is crucial, and this function outlines the essential procedures to do so. Some examples of what this role entails are:

  • Ensure that out-of-the-ordinary occurrences are recognized, and their possible effects are comprehended.

  • Including network and physical activity in the verification of protective measures and the constant monitoring of cybersecurity incidents.

Respond: The Respond operation is concerned with corrective measures to be taken in case of a detected cybersecurity issue and aids in the capability to limit the effect of a possible cybersecurity event. Some of the most important things to do in this role are:

  • Make sure that the plans are implemented in the event of a crisis.

  • Taking care of post-event communication with internal and external stakeholders.

  • Support recovery efforts and conduct forensic investigations to understand better the scope of an occurrence and how best to respond to it.

  • Take measures to limit a situation's severity and bring about its swift resolution.

  • Adapting future detection and response efforts to the lessons learned from the past is an effective method of enhancing the quality of these processes.

Recover: When cybersecurity compromises a company's systems, the Recover function will determine what needs to be done to recover those systems and any lost capabilities or services. Restoration of regular operations as soon as possible is stressed to lessen the effects of cybersecurity. Many of the necessary tasks for this function are similar to Response.

  • Ensure the company has a strategy to restore any data, cybersecurity, hardware, or other assets that cyberattacks may have compromised.

  • Put into action changes gleaned from analyses of past methods.

  • Internal and external communications are coordinated during and after a cybersecurity incident recovery.

In conclusion

It’s really important to know that, in order to align with the NIST Cybersecurity Framework, you must label all your actions with one of 5 function labels. This may sound hard, but if you have a clear glimpse of what to do in each category, then you’ll be able to figure it out in an easier way.

Fore example, the Identify label is for inventorying tools. Also, Protect includes Firewalls and Crowdstrike. Depending on their capabilities, you'd also put them in Detect with your IDS and SIEM. Respond contains incident-response tools and playbooks. Recover handles backup and recovery.
