Security Incident Classification and Prioritization Checklist

In this section, you will determine the severity level of an incident based on its impact on your organization. The goal is to classify incidents into three categories: low, medium, or high. This classification will help guide the response efforts and resource allocation for each incident. Start by identifying the key factors that affect the severity level, such as data loss, system downtime, financial impact, and potential risks to users or the general public. Next, use a standardized framework to classify incidents based on their severity levels. The classification process should be consistent across your organization to ensure fair treatment of all incidents. Consider also involving stakeholders in this process to provide input and guidance throughout.

In this section, assess the potential impact of an incident on the organization's operations, assets, finances, personnel, and environment. Identify the areas affected by the incident and estimate the severity of the damage. Consider both immediate and long-term effects, including downtime, revenue loss, and reputation damage. Evaluate the potential consequences for stakeholders, including customers, employees, investors, and partners. Determine whether any critical systems or infrastructure are compromised. Assess the likelihood and potential impact of any secondary incidents that may arise from the primary incident. This information will be used to inform decision-making around containment, eradication, recovery, and post-incident activities.

In this section, the likelihood of potential incidents is assessed to inform risk management decisions. The purpose is to evaluate the chances of undesirable outcomes arising from various sources. A systematic approach involves identifying potential causes, assessing their likelihood, and evaluating the potential impact on operations. This process requires consideration of multiple factors, including past experience, industry standards, regulatory requirements, and available data. By assigning a probability score to each identified cause, organizations can better understand where resources should be allocated to prevent or mitigate incidents. The outcome will inform risk mitigation strategies and help allocate resources effectively to address areas of highest likelihood.

In this section, the prioritized list of requirements is reviewed and refined. The team assesses each requirement's feasibility, complexity, and impact on the overall project goals. A scoring system or voting mechanism may be employed to assign weights to each requirement based on these factors. This step helps ensure that the most critical and feasible requirements are given priority in subsequent development phases. The output of this process is a revised list of prioritized requirements, which will serve as input for the next phase's planning and resource allocation.

In this step of the investigation process, the root cause analysis is conducted to identify the underlying factors that led to the problem or incident. This involves analyzing data collected from various sources, conducting interviews with relevant personnel and stakeholders, and examining historical records. The goal of root cause analysis is to determine the most likely cause of the issue, rather than just identifying a contributing factor. By doing so, it enables the team to develop targeted solutions that address the underlying problem, rather than just treating its symptoms. A structured approach to root cause analysis helps ensure a comprehensive and systematic investigation, reducing the risk of overlooking important information or drawing incorrect conclusions.

In this section, a comprehensive analysis of the findings is presented, leading to informed recommendations for future improvements. The process begins by identifying key areas of improvement based on data collection and analysis. Next, potential solutions are generated through brainstorming and research. Following this, each proposed solution is evaluated against criteria such as feasibility, cost-effectiveness, and expected impact. This evaluation process helps to narrow down the options and select the most suitable recommendations. The final step involves distilling the key takeaways and presenting them in a clear and concise manner, taking into account any stakeholder feedback or concerns.
