What are the key steps to ensure a thorough and accurate risk assessment process?

Context is king A risk exists in a context and not in a vacuum. Make sure to, that you and those who participate in the risk assessment understand the context. Security risk Security risks are dynamic and changes in the threat landscape may happen very fast. Reevaluate the context if new information becomes available in later stages of the risk assessment process. Adapt and reevaluate as you go. Business impact Evaluate and understand the potential negative business impact if the risk is actualized. In the end of the day, the only type of risk that exists is business risk. Security risks, as any other type of risk will have an impact on the business. Make sure to understand that impact.

My humble experience and the one thing I see that a lot of risk management processes are missing is the level of risk always need to be presented at the level that makes sense to who owns the risk. Ownership is one of the most underestimated and most important thing to consider here. The requirements level must come from someone that owns the the product and thereby the risks, aka the risk owner, in order to create the security requirements on a level that makes sense. Many companies are struggling with this problem. You have a very technical risk assessment from the design phase or the development phase and its not translated into the right context once transferred over to the production. Ownership and accountability is everything.

1.- Understand the business: List business services and industrial processes, identify owners, and assign importance levels for context and impact understanding. 2.- Identify assets: Create an inventory linked to services and processes, determining qualitative asset value. 3.- Identify vulnerabilities: Assess cybersecurity maturity, pinpointing procedural gaps, awareness levels, and technical weaknesses for each asset. 4.- Threat modeling: Analyze up to 10 likely threats, evaluating actors, capabilities, and TTPs. Offensive mindset. 5.- Risk scoring: Based on the threat model, determine the likelihood of exploitation for each vulnerability, considering asset context for impact assessment across services and processes.

Comprehensive Risk Assessment process may follow the following steps: 1. Assets Identification and their Criticality Ranking 2. Defining Information Classification and Sensitivity Policy, based on criticality ranking and Threat Landscape of the entity 3. Vulnerability Assessment of Assets and Identifying underlying risk 4. Impact Analysis and Likelihood of Occurrence of Risks 5. Applicable Internal Controls Structure in place 6. Residual Risk left, after Inherent Risk, Control Risk and Audit Risk 7. Mitigating Controls 8. Continual process of Monitoring and Measuring Risks

Determining the Controls: Identify existing controls and evaluate their effectiveness. Along with recommending additional controls or modifications to existing ones, wherever necessary. Estimate Residual Risk: Residual risk refers to the remaining risk after all mitigation measures have been implemented. It's the level of threat that still exists, even after controls are in place. It's essential to understand that, the goal is to minimize the 'residual' aspect to the lowest possible level, recognizing that reaching an absolute zero might be challenging. Documentation: Ensuring that every step, decision, and rationale is well-documented, for audits, training, and future risk assessments.

One of the biggest risks to any ISMS is becoming redundant or irrelevant. With the ever changing landscape of information systems, perhaps the biggest challenge is to identify the shifts. Continuous review and update forms the bedrock of risk identification. Checks like regulatory and voluntary compliances, regular audits, vulnerability assessment, etc go a long way in proactive risk identification. These can be coupled with continuous monitoring, asset inventory management, scenario planning, threat intelligence, etc. to form a comprehensive risk identification policy.

Risk identification is an art form, honed through years of experience and vigilance. It's not just about recognizing obvious threats but uncovering hidden dangers—those that lie dormant until conditions are ripe. My approach has always been to combine data-driven methods with intuitive insights. This involves tapping into diverse information sources, from incident reports to employee feedback, and contextualizing them within a broader industry and global landscape. A robust risk identification process is akin to putting together a jigsaw puzzle; each piece provides a glimpse into potential vulnerabilities and emerging threats, shaping a comprehensive risk landscape.

Begin by cataloging assets and understanding their vulnerabilities. Assess potential threats, ranging from external cyber attacks to internal lapses. Consider the human element, including user behaviors and awareness. Analyze existing security controls and their efficacy. Stay abreast of evolving cyber threats and technological changes. Leverage threat intelligence sources. Conduct regular penetration testing and vulnerability assessments. Collaborate with stakeholders to gain diverse insights. The process should be dynamic, adapting to emerging risks.

Identifying risks is the subsequent step in the risk assessment process. Risks are the result of threats and vulnerabilities that have the potential to negatively impact your Information Security Management System (ISMS). To pinpoint these risks, you should gather data from a variety of sources, including historical records, incident reports, audits, surveys, interviews, and direct observations. By employing a risk identification framework like OCTAVE, FAIR, or NIST, you can systematically and comprehensively document and organise your findings. This structured approach aids in identifying both existing and potential risks, facilitating a more effective risk assessment.

Using a methodology based on the ISO 25010 standard, a Software Risk Assessment involves a thorough analysis of your application landscape to help you to solve complex IT strategy issues, such as: ? Late delivery of projects ? Slow pace of innovation ? Legacy system challenges ? Productivity issues Identifying risks within the ISMS is a crucial stride towards building a more resilient and secure system. This method not only aids in recognizing existing vulnerabilities but also helps anticipate potential risks. We emphasize the importance of gathering evidence from diverse sources to create a robust risk profile, allowing for a more informed and proactive risk management strategy within the ISMS.

In any practical scenario, risk analysis would be a mix of subjective judgements and hard numbers often driven by organisational policies or compliance adherence. These in turn would be guided by the impact (actual or expected) each of the identified risks carry.

1. Estimate the likelihood and impact of each identified risk. 2. Use qualitative, quantitative, or hybrid risk analysis methods for measurement. 3. Compare risks based on probability and severity. 4. Employ a risk matrix, like a 3x3 or 5x5 grid, for visualization. 5. Categorize risks according to their level of risk for better prioritization.

Evaluate the potential impact and likelihood of identified threats. Prioritize risks based on severity and strategic importance. Consider the interconnectedness of systems and potential cascading effects. Gauge the effectiveness of existing security controls and their ability to mitigate risks. Factor in the evolving threat landscape and vulnerabilities. Employ quantitative and qualitative analysis techniques to refine risk assessments. Collaborate with experts to gain diverse perspectives. Continuous monitoring and scenario analysis enhance the accuracy of risk analysis.

Start with threat identification; this will facilitate better risk identification and analysis. Using tools such as threat modeling allows for a more precise identification of risks relevant to your business, organization, or IT system. This is crucial as it enables a more focused approach to the threats that are particularly relevant to you.

Employ quantitative and qualitative metrics to gauge the significance of each risk. Consider the context of the organization, including its risk appetite and strategic goals. Evaluate the effectiveness of existing security measures in addressing specific risks. Prioritize mitigation efforts based on the severity and strategic relevance of each risk. Regularly update assessments to adapt to evolving threats. Engage stakeholders to ensure a holistic perspective.

Evaluating risks is the fourth step in the risk assessment process and is crucial to determine whether identified risks are acceptable or unacceptable. This assessment is based on your organisation's established risk appetite and tolerance. Risk appetite represents the level of risk your organisation is willing to accept in order to achieve its objectives, while risk tolerance specifies the range of variation from the established risk appetite that is still acceptable. To aid in this evaluation, organisations often employ risk evaluation criteria such as a scoring system or ranking scale. These criteria help prioritise and justify decisions regarding which risks should be addressed and how they should be managed.

In line with SIG's SRA practices, the evaluation of risks within an ISMS closely resonates with methodologies. By determining the acceptability of risks based on a defined risk appetite & tolerance, our approach echoes SIG's emphasis on structured risk assessment. We utilize similar risk evaluation criteria(scoring systems or ranking scales) to align with SIG's best practices. This process ensures prioritization and justification of risk decisions, a fundamental aspect emphasized within both SIG's software risk assessment and our approach to ISMS risk evaluation. Through this aligned strategy, we aim to uphold security excellence & fortify systems against potential threats, remaining consistent with high standards for SRA.

The fourth step in the risk assessment process is risk evaluation. This phase involves determining whether the risks, which have been analysed, are acceptable or unacceptable based on your organisation's risk appetite and tolerance. Your risk appetite reflects the amount of risk you are willing to assume to achieve your objectives, while your risk tolerance defines the acceptable deviation from your risk appetite. To aid in this evaluation, you should utilise risk evaluation criteria, such as a scoring system or ranking scale, to effectively prioritise and justify your decisions. This process ensures that your risk management efforts align with your organisation's specific risk tolerance and strategic goals.

Risk evaluation is a delicate balancing act, blending objective analysis with strategic business insights. It's about aligning risks with organizational appetites and tolerances, which often varies significantly across different sectors and corporate cultures. This step transcends the technical realm, requiring a deep understanding of the organization's strategic goals, market positioning, and stakeholder expectations. My focus here is on enabling informed decision-making, where risks are not just seen as threats but as potential drivers of innovation and change.

1. Select and implement appropriate risk treatment options: avoid, reduce, transfer, or accept risks. 2. Use a risk treatment plan, such as a risk register or action plan. 3. Document and monitor risk treatment actions. 4. Consider the costs and benefits of each treatment option. 5. Account for residual risks that remain after treatment.

Treating risks is where strategic planning meets practical execution. In my decades of experience, I've seen that effective risk treatment requires a nuanced understanding of not just cybersecurity but also the organization's operational dynamics. It's about crafting solutions that are not only technically sound but also pragmatic and aligned with the business's core objectives. This step is not just about mitigating risks but also about leveraging them for organizational growth and resilience, ensuring that the cybersecurity strategy supports and enhances the overall business strategy.

Risk treatment is the critical fifth step in the risk assessment process. It involves strategic actions to manage identified risks. Options include avoidance, reduction, transfer, or acceptance. A risk treatment plan, like a risk register or action plan, is crucial for documenting and monitoring actions. Consider the costs and benefits of each option and be aware of any residual risks that may remain. Effective risk treatment ensures proactive risk management, helping organisations make informed decisions to mitigate potential threats to their operations and objectives.

Treating the risks marks the fifth step in the risk assessment process. This involves taking action to address the risks that have been evaluated. Your risk treatment options may include avoiding, reducing, transferring, or accepting the identified risks. To guide and document these actions, a risk treatment plan, such as a risk register or risk action plan, should be utilised. Additionally, you should carefully assess the costs and benefits associated with each treatment option and take into account the residual risks that may persist even after treatment measures have been applied. This comprehensive approach ensures that risks are effectively managed and mitigated in alignment with your organisation's objectives and constraints.

Involve stakeholders. Stakeholders can provide valuable insights into the effectiveness of your risk treatment actions and the risks that you are facing. Use data and metrics. Data and metrics can help you to measure and track your risk performance over time. Be objective. It is important to be objective when reviewing your risk performance. This means being willing to identify areas where improvement is needed.

Consistency is king. Risks are often reviewed following 'typical'. 'standard' frequencies of once or twice per year. Risks and their respective mitigating controls are extremely dynamic, especially when associated with technology. Therefore, reviews should be conducted on an on-going basis, ensuring that it forms part of day-to-day ops. No need to reinvent the wheel or overcomplicating matters. A simple structure and schedule to ensure consistency will do the trick.

The final step in the risk assessment process is reviewing the treated risks. This involves assessing the effectiveness and efficiency of the risk treatment actions, as well as identifying and addressing any new or changed risks that may have arisen. A risk review process, which can include periodic audits or a continuous feedback loop, should be employed to measure and enhance risk performance. It's essential to communicate and report the results and recommendations to relevant stakeholders and authorities to ensure transparency and ongoing improvement in risk management practices.

Trust but Verify! As we have seen from the many breaches in 2023, cybersecurity certifications are worthless at predicting which organizations will be breached. Sadly, these certifications/attestations are not risk assessments. An actual RA will verify the controls are in place and be rather prescriptive. For example, looking at strong passwords. Asking for a screenshot of the actual password configuration screen in MS ActiveDirectory rather than looking at the password policy written document. Make sure the PRACTICE matches or exceeds the POLICY!

Validate controls! Do not expect implementations of risk mitigating controls to just 'work' if they are never verified and validated.

Prioritizing risks based on maintainability involves a comprehensive evaluation of the impact of risks on the long-term sustainability of software systems. It employs various metrics, analyses, and strategies to ensure that maintainability concerns are addressed effectively and continuously.

Engage Stakeholders: Involve stakeholders for comprehensive risk understanding & effective mitigation. Document the Process: Maintain clear documentation for future reference, audits, & improvements. Continuous Training & Awareness: Provide ongoing training for threat awareness, empowering personnel to identify & report risks. Integration with Business Processes: Align RA with broader business processes for a cohesive security strategy. Regular Testing & Simulation: Conduct regular exercises to validate mitigation measures, refining strategies for real-world effectiveness. Adaptability to Emerging Threats: Build flexibility to adapt to emerging threats, ensuring a proactive response.
