A business impact analysis (BIA) is a process that helps identify and evaluate the potential effects of disruptions or incidents on the organization’s mission, objectives, and operations. A BIA should be periodically executed to verify the effectiveness of the controls that are implemented to prevent, mitigate, or recover from such disruptions or incidents12.

According to the CISM Manual, a BIA should be performed at least annually for critical systems and processes, and more frequently for non-critical ones3. A BIA should also be updated whenever there are significant changes in the organization’s environment, such as new regulations, technologies, business models, or stakeholder expectations3. A BIA should not be used to validate vulnerabilities on environmental changes (A), analyze the importance of assets (B), or check compliance with regulations ©, as these are not the primary purposes of a BIA.

The best approach to developing an incident escalation process is to classify incidents based on the information assets affected, because this will help to determine the impact and severity of the incidents, as well as the appropriate response and recovery actions. The information assets affected by an incident can indicate the potential loss of confidentiality, integrity, or availability of the information, as well as the legal, regulatory, contractual, or reputational implications. By classifying incidents based on the information assets affected, the organization can prioritize the incidents and escalate them to the relevant stakeholders and authorities.

The most important information to include in monthly information security reports to the board is the trend analysis of security metrics. Security metrics are quantitative and qualitative measures that indicate the performance and effectiveness of the information security program and the alignment with the business objectives. Trend analysis is the process of comparing and evaluating the changes and patterns of security metrics over time. Trend analysis can help to identify the strengths and weaknesses of the information security program, the progress and achievements of the security goals and initiatives, the gaps and opportunities for improvement, and the impact and value of the information security investments. Trend analysis can also help to communicate the current and future security risks and challenges, and the recommended actions and strategies to address them. Trend analysis can provide the board with a clear and concise overview of the information security status and direction, and enable informed and timely decision making.
