A Virtual Private Network (VPN) provides additional protection to messages transmitted using portable wireless devices by creating a secure and encrypted tunnel for data transmission. This helps protect the data from being intercepted or accessed by unauthorized entities. While encryption secures the content of the messages, a VPN secures the transmission path, adding an extra layer of security.

References: The use of VPNs for enhancing the security of mobile devices is discussed in ISACA’s resources. VPNs are recommended as a measure to protect data in transit, especially when using public or unsecured networks, which is a common scenario for portable wireless devices

The MOST critical thing to guiding and managing security activities throughout an organization to ensure objectives are met is establishing metrics to measure and monitor security performance. This is because metrics provide quantifiable and objective data that can be used to evaluate the effectiveness and efficiency of security activities, as well as identify gaps and areas for improvement. Metrics also enable communication and reporting of security performance to stakeholders, such as senior management, board members, auditors, regulators, customers, etc. The other options are not as critical as establishing metrics, because they either involve spending money without knowing the return on investment (A), adopting standards without customizing them to fit the organization’s context and needs (B), or conducting training without assessing its impact on behavior change (D).
