A balanced scorecard most effectively enables information security govern-ance. Information security governance is the process of establishing and maintaining a framework to provide assurance that information security strategies are aligned with and support business objectives, are consistent with applicable laws and regulations, and are managed effectively and efficiently1. A balanced scorecard is a tool for meas-uring and communicating the performance and progress of an organization toward its strategic goals. It typically includes four perspectives: financial, customer, internal pro-cess, and learning and growth2. A balanced scorecard can help information security managers to:

•Align information security objectives with business objectives and communicate them to senior management and other stakeholders

•Monitor and report on the effectiveness and efficiency of information security processes and controls

•Identify and prioritize improvement opportunities and corrective actions

•Demonstrate the value and benefits of information security investments

•Foster a culture of security awareness and continuous learning

Several sources have proposed models or frameworks for applying the balanced scorecard approach to information security governance34 . The other options are not the most effective applications of a balanced scorecard for information security. Pro-ject management is the process of planning, executing, monitoring, and closing pro-jects to achieve specific objectives within constraints such as time, budget, scope, and quality. A balanced scorecard can be used to measure the performance of individual projects or project portfolios, but it is not specific to information security projects. Per-formance is the degree to which an organization or a process achieves its objectives or meets its standards. A balanced scorecard can be used to measure the performance of information security processes or functions, but it is not limited to performance measurement. Risk management is the process of identifying, analyzing, evaluating, treating, monitoring, and communicating risks that affect an organization’s objec-tives. A balanced scorecard can be used to measure the risk exposure and risk appetite of an organization, but it is not a tool for risk assessment or treatment.

After an intrusion has been detected and contained, the system should be recovered to a known and trusted state. The best practice for ensuring the integrity of the recovered system is to install the OS, patches, and application from the original source, such as the vendor’s website or media. This way, any malicious code or backdoors that may have been inserted by the intruder can be eliminated. Restoring the OS, patches, and application from a backup may not guarantee the integrity of the system, as the backup may have been compromised or outdated. Restoring the application and data from a forensic copy may preserve the evidence of the intrusion, but it may also reintroduce the vulnerability or malware that allowed the intrusion in the first place. Removing all signs of the intrusion from the OS and application may not be sufficient or feasible, as the intruder may have made subtle or hidden changes that are difficult to detect or undo.

The BEST practice for ensuring the integrity of the recovered system after an intrusion is to restore the OS, patches, and application from a backup. This will ensure that the system is in a known good state, without any potential residual malicious code or changes from the intrusion. Restoring from a backup also enables the organization to revert to a previous configuration that has been tested and known to be secure. This step should be taken prior to conducting a thorough investigation and forensic analysis to determine the cause and extent of the intrusion.

Inconsistent device security is the primary challenge for an information security manager when deploying a bring your own device (BYOD) mobile program in an enterprise because it increases the risk of data breaches and compromises. A BYOD mobile program allows employees to use their personal devices, such as smartphones, tablets, or laptops, to access the organization’s network, applications, and data. However, personal devices may have different operating systems, versions, configurations, and security settings than the organization’s standard devices. Moreover, personal devices may not be updated regularly, may have unauthorized or malicious apps installed, or may not have adequate protection against malware or theft. Inconsistent device security makes it difficult for the information security manager to enforce and monitor the security policies and controls across all devices, as well as to ensure compliance with the regulatory requirements for data privacy and security. Therefore, inconsistent device security is the correct answer.
