The National Institute of Standards and Technology’s Cybersecurity Framework (CSF) is known in cybersecurity as the gold standard framework for computer security guidance; it can assess and improve an organization’s ability to prevent, detect, and respond to cyber-attacks. The NIST Risk Management Framework guides conducting risk assessments in the parameters of the NIST CSF. It can be used to communicate cyber risk to business leaders and personnel working outside information security. These two frameworks work in tandem to create a well-rounded risk management protocol that is customizable and specific to the needs of any company. Given its ability to contour to any organization and its comprehensiveness, the NIST Special Publication 800-30 is one of the most complex and challenging to execute.

Summary of NIST 800-30
The purpose of special publication 800-30 is to provide guidance for conducting risk assessments per industry recommendations and standards. NIST SP 800-30 is explicitly used to conduct NIST cyber risk assessments and translate cyber risk in a way that can be understood by the Board and CEO. common language between technical and business leadership helps both parties make more informed budgeting decisions and assists in making targeted choices on how to implement cybersecurity initiatives. This is expressed through threat type, business impact, and financial impact. To do this, a baseline risk assessment is required to judge the current standard of operation within the system, flag potential security issues, and make improvements. This baseline will also measure how impactful those decisions are to the integrity of a given cybersecurity initiative. It is critical to have a real-time solution to support this since there are so many security controls to be mapped and measured; using a dated logging method like spreadsheets is insufficient.
How to Implement NIST 800-30 Methodology
To satisfy NIST 800-30, your IT systems must be reported upon. For this, hardware, software, system interfaces, the data on all information technology systems, the critical capabilities of said data and its sensitivity, who has access to the system, and the system’s objectives and functions are required. Also, the threat history of the systems, as well as the previous and current vulnerabilities. This is observed to establish threat vectors and generate a threat report statement. Previous risk assessments will also be observed to measure vulnerabilities and map them to their respective requirements, followed by a control analysis to develop a list of current and future planned control implementations. These processes are conducted to pinpoint the weaknesses of information systems and organizations as a starting point to improve upon based on the positioning of your system development life cycle.
The next step is conducting a likelihood determination to estimate the probability of an infrastructure weakness being exploited by a cyber threat or event. Additionally, an impact analysis is performed to evaluate the result of an event happening and the losses that can result from such an adverse cyber event, such as a beach or attack, followed by a risk determination of identified risks.
From there, recommendations and implementation plans can be created for risk mitigation by reducing the likelihood of a threat and mitigating the impact of an event that can cause an unfortunate circumstance.
NIST 800-30 Steps
| NIST 800-30 Step | Description |
| 1. Categorize Information Systems | Determine the sensitivity and criticality of information systems. |
| 2. Identify Information System Components | Identify the components of the information system, including hardware, software, networks, and personnel. |
| 3. Identify Threats | Identify potential threats that could compromise the information system's confidentiality, integrity, or availability. |
| 4. Identify Vulnerabilities | Identify weaknesses in the information system that threats could exploit. |
| 5. Determine Likelihood and Impact | Assess the likelihood of each threat occurring and the potential impact if it does. |
| 6. Determine Risk | Calculate the overall risk associated with each threat and vulnerability. |
| 7. Select Risk Responses | Develop strategies to address the identified risks. |
| 8. Implement Risk Responses | Put the selected risk response strategies into action. |
| 9. Monitor and Evaluate | Continuously monitor and reassess your risk posture. |

Which NIST SP-800 Publications are Relevant to Conducting Cyber Security Risk Assessment?
NIST 800-30 and NIST 800-37 are two key publications relevant to conducting cybersecurity risk assessments. 800-30 provides a step-by-step guide for conducting risk assessments, outlining the process from identifying assets to developing response strategies. 800-37, on the other hand, focuses on the risk management framework, offering a comprehensive approach to managing information security risks across an organization. Additionally, NIST Special Publication 800-53 provides a catalog of security controls that can be used to mitigate identified risks. These three publications and other relevant NIST publications offer a valuable resource for organizations seeking to conduct effective cybersecurity risk assessments.
