The primary responsibility of an information security manager in an organization that is implementing the use of company-owned mobile devices in its operations is to review and update existing security policies. Security policies are the foundation of an organi-zation's security program, as they define the goals, objectives, principles, roles, respon-sibilities, and requirements for protecting information and systems. Security policies should be reviewed and updated regularly to reflect changes in the organization's envi-ronment, needs, risks, and technologies1. Implementing the use of company-owned mobile devices in its operations is a significant change that may introduce new threats and vulnerabilities, as well as new opportunities and benefits, for the organiza-tion. Therefore, the information security manager should review and update existing security policies to address the following aspects2:
* The scope, purpose, and ownership of company-owned mobile devices
* The acceptable and unacceptable use of company-owned mobile devices
* The security standards and best practices for company-owned mobile devices
* The roles and responsibilities of users, managers, IT staff, and vendors regarding compa-ny-owned mobile devices
* The procedures for provisioning, managing, monitoring, and decommissioning company-owned mobile devices
* The incident response and reporting process for company-owned mobile devices By reviewing and updating existing security policies, the information security manager can ensure that the organization's security program is aligned with its business objec-tives and risk appetite, as well as compliant with applicable laws and regulations. The other options are not the primary responsibility of an information security manager in an organization that is implementing the use of company-owned mobile devices in its operations. They are possible actions or controls that may be derived from or support-ed by the updated security policies. Requiring remote wipe capabilities for devices is a technical control that can help prevent data loss or theft in case of device loss or com-promise3. Conducting security awareness training is an administrative control that can help educate users about the security risks and responsibilities associated with using company-owned mobile devices. Enforcing passwords and data encryption on the de-vices is a technical control that can help protect data confidentiality and integrity on company-owned mobile devices.

The best course of action to prevent further damage is to isolate the endpoint device. Isolating the endpoint device will prevent the compromised system from connecting to other systems on the network and spreading the infection. Other possible courses of action include wiping and resetting the endpoint device, running a virus scan, and powering off the endpoint device. However, these actions will not prevent the compromised system from continuing to spread the infection.

Performing a risk assessment of the access rights is the best way to address the concern of conflicting access rights during the integration of two companies. A risk assessment will help to identify and prioritize the threats and vulnerabilities that affect the access rights of both companies, as well as the potential impact and likelihood of information exposure. A risk assessment will also provide a basis for selecting and evaluating the controls to mitigate the risks. According to NIST, a risk assessment is an essential component of risk management and should be performed before implementing any security controls1. The other options are not the best ways to address the concern of conflicting access rights during the integration of two companies, but rather possible subsequent actions based on the risk assessment. Reviewing access rights as the acquisition integration occurs may be too late or too slow to prevent information exposure. Escalating concerns for conflicting access rights to management may not be effective without evidence or recommendations from a risk assessment. Implementing consistent access control standards may not be feasible or desirable for different systems or business units.
