Decreasing false positives is the best indicator that the information security manager has tuned the system to address senior management’s concern that the organization’s intrusion prevention system (IPS) may repeatedly disrupt business operations. False positives are alerts generated by the IPS when it mistakenly blocks legitimate traffic or activity, causing disruption or downtime. Decreasing false positives means that the IPS has been configured to reduce such errors and minimize unnecessary interruptions. Increasing false negatives is not a good indicator because it means that the IPS has failed to detect or block malicious traffic or activity, increasing the risk of compromise or damage. Decreasing false negatives is not a good indicator because it does not affect business operations, but rather improves security detection or prevention. Increasing false positives is not a good indicator because it means that the IPS has increased its errors and interruptions, worsening senior management’s concern. References: penetration-testing

= Continuous monitoring is the process of collecting, analyzing, and reporting on the security status of an organization’s information systems and networks. Continuous monitoring enables an organization to identify and contain security incidents by providing timely and accurate information on the security events, alerts, incidents, and threats that may affect the organization. Continuous monitoring also helps to measure the effectiveness and compliance of the security controls, policies, and procedures that are implemented to protect the organization’s information assets. Continuous monitoring can be performed using various tools and methods, such as security information and event management (SIEM) tools, intrusion detection and prevention systems (IDS/IPS), vulnerability scanners, log analyzers, and audit trails.

Annualized loss resulting from security incidents is the most appropriate metric to demonstrate the effectiveness of information security controls to senior management, as it quantifies the financial impact of security breaches on the organization’s assets, operations, and reputation. This metric helps to communicate the value of security investments, justify the security budget, and prioritize the security initiatives based on the potential loss reduction. Annualized loss resulting from security incidents can be calculated by multiplying the annualized rate of occurrence (ARO) of an incident by the single loss expectancy (SLE) of an incident. ARO is the estimated frequency of an incident occurring in a year, and SLE is the estimated cost of an incident. For example, if an organization estimates that a ransomware attack may occur once every two years, and that each attack may cost $100,000 to recover, then the annualized loss resulting from ransomware attacks is $50,000 ($100,000 / 2).

The information security manager should first assess the risk to business operations that are caused by the information security issues reported by internal audit. This will help to prioritize the remediation actions and allocate the necessary resources. Creating a security exception, performing a gap analysis, or performing a vulnerability assessment are possible subsequent steps, but they are not the first action to take.
