What is the purpose of a Cost Benefit Analysis in security?

The purpose of a Cost Benefit Analysis (CBA) in the context of security is primarily to compare the costs associated with implementing security countermeasures against the potential losses that could occur if those countermeasures were not in place. This analytical approach helps organizations justify security investments by assessing the financial implications of preventive measures.

When performing a CBA, organizations look at the estimated costs of various security controls, such as hardware, software, personnel, and training, and weigh them against the potential financial impact of incidents like data breaches, theft, or non-compliance penalties. By identifying the possible losses or damages that could occur due to security failures, decision-makers can prioritize investments in security measures that offer the most significant risk reduction relative to their costs, ultimately aiding in the protection of assets and resources.

Other options, while they may be relevant to security planning in their own right, do not directly address the specific focus of a Cost Benefit Analysis. For instance, evaluating implementation times or assessing training needs are important parts of a security strategy but are not the core function of a CBA. Similarly, determining the market value of data may play a role in broader financial assessments but does not encapsulate the comparative analysis of costs and potential losses that defines a CBA
