What Is a Cybersecurity Risk Assessment?

‍

A cybersecurity risk assessment, or cyber risk assessment, is a standardized process that organizations have established along with their implementation of cloud-based technologies to discover the accompanying vulnerabilities and threats. These assessments leverage the available, relevant data to identify the likelihood of various cybersecurity events occurring along with the potential impact should they come to fruition.

‍

There are several different types of cybersecurity assessments and maturity measurement models, all of which can illuminate multiple perspectives regarding the organization's exposure. However, when the assessment is complete, chief information security officers (CISOs) and other cyber leaders should ultimately be left with actionable insights that help them make more strategic risk management decisions (such as accept, mitigate, or transfer), optimize limited resources, and achieve a state of cyber resilience.

‍

‍

Why Detailed Cyber Risk Assessments Are Crucial

‍

In the 1980s, after first transferring portions of their business operations to the digital realm, major corporations began to fall victim to cyber attacks. As market losses and reputational damage started to accumulate, it became evident to stakeholders that they needed a more holistic understanding of the various new risks their organizations opened themselves up to by adopting cloud technologies and other digital innovations.

‍

Indeed, running a successful business, especially in the 21st century as attack surfaces continue to expand, demands that all forms of risk are accounted for and factored into risk appetite levels as well as the broader organizational strategy.

‍

By turning towards risk assessments specifically targeted at unearthing cyber vulnerabilities, these stakeholders found that they were able to proactively discover the cyber loss scenarios their companies were most prone to and, therefore, invest the necessary resources to mitigate the occurrence probabilities and respective severities.

‍

As Austrian-American management expert Peter Drucker famously said, it's impossible to manage what has not been measured, especially when it comes to risk. A cybersecurity assessment and its subsequent findings are, therefore, essential for any organization that conducts activities online and endeavors to develop robust strategies that lead to high-end resilience.

‍

The Necessity of Continuous Risk Assessment in Cybersecurity

‍

The cyber risk landscape is unique in many ways, not least of which is that it tends to evolve at a much faster rate than other forms of business risk. This rapid progression is driven by the steady emergence of new technologies and resulting innovative attack methods. Consequently, CISOs would do well to adopt a cybersecurity risk assessment that is iterative and can generate results on demand. 

‍

An organization's risk posture needs to be re-assessed, at minimum, every quarter, and if the assessment type requires too much manual work, then it becomes counterproductive. To ensure security measures remain proactive rather than reactive, cybersecurity leaders should select a risk assessment type that's flexible enough to account for any internal changes and likewise incorporates the latest threat intelligence.

‍

The Benefits of Conducting a Cybersecurity Risk Assessment

‍

While the overarching benefit of a cyber risk assessment - leveraging the results to build a more robust, data-driven cybersecurity strategy that enhances security posture and builds resilience - may be apparent, there are likewise several more granular benefits that conducting an assessment brings. For instance, after evaluating the organization's cyber risk, stakeholders will have: 

‍

• A comprehensive view of the organization, including where the crown jewels are situated and how exposed they are. 
• A complete understanding of those factors that most significantly drive cyber risk, as well as the loss scenarios the company is most likely to face. 
• A better idea, in the case of a cyber risk quantification assessment, of how they should determine their risk appetite, tolerance, and benchmark levels.

‍

Moreover, with all of the uncovered insights, CISOs are better equipped to optimize their limited resources, reducing the potential average severity of cyber events in the upcoming year and pursuing initiatives that yield a positive ROI. Best of all, they'll be armed with the information necessary for defending their cybersecurity strategies to the board and demonstrating long-term progress.

‍

‍

Selecting a Cyber Risk Assessment: The Key Considerations

‍

There are several types of cybersecurity risk assessments available to CISOs, so before selecting one, it's important to establish clear objectives regarding what needs to be improved. For instance, vulnerability assessments are used to identify overall weaknesses within the organizations, while third-party service provider risk evaluations specifically focus on vendor and external solution risk. Each provides critical yet distinct insights that help inform an organization's approach to strengthening its security posture.

‍

Another consideration to keep in mind is the cyber risk assessment’s time-to-value. Some approaches, such as the FAIR framework, fall short due to the intensive, manual data-gathering process required to render results. Amassing data is time-consuming, and by the time outcomes are calculated, they're most likely to be obsolete. On-demand CRQ models, on the other hand, provide organizations with a comprehensive view of cyber risk within minutes.

‍

Integration capabilities should likewise be taken into account before an assessment is chosen. Cybersecurity risk assessment tools should be able to incorporate information already existing within the organization's infrastructure, such as data from previous assessments, security monitoring system logs, and incident reports. Integrations reduce the likelihood of inconsistencies and, thus, provide a more accurate, in-depth view of the organization's cybersecurity posture.

The 6 Fundamental Steps of a Cybersecurity Risk Assessment  

‍

Despite the different scopes or purviews each cyber risk assessment may have, they should all follow the same basic direction. Each of these steps is critical for unearthing the relevant data and leveraging findings to upgrade cybersecurity programs cost-effectively. 

‍

‍Step 1: Identify Assets and Respective Value

‍

The first step in any risk assessment for cybersecurity should involve identifying and mapping the organization's network structure and critical assets, including data, applications, and third-party service provider solutions. These components should then be evaluated according to their business operational value. For example, a CISO may start by documenting all employee endpoints, segmenting them according to business unit, listing the associated technologies used, and documenting how many data records each endpoint has access to.

‍

This process helps cyber risk managers isolate those particular enterprise divisions that are essential to operations and ensure that mitigation efforts are focused on those areas in the ensuing action plan rather than those less crucial to business continuity and reputation.

‍

Step 2: Determine Cyber Threats and Vulnerabilities

‍

The second step includes identifying the cyber vulnerabilities and threats amongst these various assets and throughout the system. Vulnerabilities are the weaknesses in an organization's IT environment that could be exploited during a cyber event, such as solution misconfigurations, weak passwords, and insufficiently protected endpoints. Regardless of how minimal a structural flaw may seem, it's important to thoroughly assess all possibilities to ensure no critical weak points are overlooked. 

‍

Threats, which refer to the methods cyber actors will use to exploit said vulnerabilities, likewise must be documented. Threats can be both internal and external and include tactics such as phishing scams, malware, or DDoS attacks. Identifying all of these vulnerabilities and threats allows organizational leaders to understand where they are most exposed and gain insight into the potential pathways attackers might use to infiltrate their systems.

‍

Step 3: Calculate Objective, Data-Driven Risk Levels

‍

Once CISOs have pinpointed their infrastructure assets and respective vulnerabilities and threats, the next step is to calculate the level of risk associated with each. Cyber risk managers usually create a risk register to keep track of everything and organize the risk scenarios in such a way that their consequences are easily comparable. Calculating risk involves assessing both the likelihood of a specific risk scenario and the potential impact it would have on the organization's assets if the incident occurred.

‍

However, rather than relying solely on scoring systems or subjective assessment measures, such as risk matrices, stakeholders would do well to also adopt data-driven cyber risk quantification models. This augmentation provides a more precise understanding of the financial and operational implications of potential cyber incidents, allowing CISOs to more easily discuss cybersecurity matters with non-technical executives and subsequently develop programs that optimally align with the broader business strategy.

‍

‍

Step 4: Develop a Prioritization-Based Action Plan

‍

Based on the quantified findings, such as how much the specific risk is likely to cost the business financially or how much downtime it may cause, on average, CISOs can then design management strategies that target those risk scenarios most likely to occur or that have the most severe consequences. This prioritization is crucial, as cybersecurity resources are undoubtedly limited and must be allocated based on where they will have the most significant impact in safeguarding the organization's resilience.

‍

‍

For example, cyber risk quantification may illuminate that a specific vulnerability will, on average, lead to a data breach that causes nearly $4 million worth of loss. In comparison, a ransomware attack might only end up costing $630 thousand. Naturally, investing resources into mitigating the former’s risk should be the priority. 

‍

CRQ also allows cybersecurity teams to calculate the ROI of various initiatives, such as security control upgrades or new solutions, providing further insight into whether they add business value and should, therefore, be prioritized. If patching a critical vulnerability costs $2 million, for instance, but only reduces the organization's financial exposure, on average, by $1 million, it may not be worth mitigating internally.

‍

Developing a data-driven, priority-based action plan helps to ensure that resources, be they financial, technological, or personnel, are allocated according to where they will have the greatest impact, both in terms of facilitating cyber resilience and overall company growth. 

‍

Step 5: Implement the Strategy and Measure Results

‍

The next step is the most tactical one: implementation. This process typically involves deploying security patches, upgrading infrastructure, onboarding new cybersecurity tools, or conducting cyber awareness training sessions. Each project should be executed according to an agreed-upon plan, and if there are any changes, they should be discussed with colleagues to ensure alignment with broader business goals. 

‍

Measuring the impact of these implementations is equally, if not more, important. CISOs need to monitor key metrics over time, such as reduction of downtime or mean time to detection. However, it's critical to measure the tangible impact of these accomplishments as well. For instance, if the mean time to detection was minimized by 20%, CISOs should be able to translate that achievement into terms non-technical executives and board members understand.

‍

Step 6: Make a Regular Assessment Schedule for Continuous Improvements

‍

A one-time cybersecurity risk assessment (and the subsequent action plan) does not provide enough information to keep the organization resilient for a prolonged period. Considering the rate at which cyber threats evolve and new risks emerge, CISOs must establish a schedule that includes reassessing the organization's cyber posture on a quarterly basis, at minimum, ensuring that the current level of security control maturity is meeting the demands of the new risk landscape.

‍

‍

Another reason to conduct regular cyber risk assessments is that it enhances trust between decision-makers and the cybersecurity department. The more that the CISO communicates with non-technical executives, the more these business leaders will understand how their investments are paying off over time. It also helps to ensure that cybersecurity remains top-of-mind, a critical factor in fostering a cyber-aware corporate culture.

‍

Identifying the Weaknesses to Build a State of Cyber Resilience

‍

CISOs will not be able to elevate their organizations' cybersecurity postures to an acceptable level if they remain ignorant of the spectrum of vulnerabilities and risks faced amid the current cyber risk landscape. Indeed, achieving a state of cyber resilience requires that system weaknesses be properly identified and assessed, thus equipping cybersecurity leaders with the insights to make informed decisions and optimize their resources to the greatest extent.

‍

A comprehensive cybersecurity risk assessment serves as the foundation for uncovering this crucial information, allowing organizations to have a deeper understanding of where their crown jewels lay and how exposed they are to malicious cyber actors. Without this foundational knowledge, any effort to build a robust cybersecurity uplift strategy will lack the precision and focus necessary for driving meaningful improvements and systematically measuring the organization's progress over time.
