The first step in developing an information security strategy is to identify key stakeholders who can provide support, guidance and resources for information security initiatives. These stakeholders may include senior management, business unit leaders, legal counsel, audit and compliance officers and other relevant parties. By engaging these stakeholders early on, an information security manager can ensure that the strategy aligns with business objectives and expectations, as well as gain buy-in and commitment from them. Determining acceptable levels of risk, creating a roadmap and performing a gap analysis are all important steps in developing an information security strategy, but they should follow after identifying key stakeholders.

The primary purpose for continuous monitoring of security controls is to ensure the effectiveness of controls. This involves regularly assessing the controls to ensure that they are meeting their intended objectives, and that any potential weaknesses are identified and addressed. Continuous monitoring also helps to ensure that control gaps are minimized, and that systems are available and aligned with compliance requirements.

The primary purpose of continuous monitoring of security controls is to ensure that the controls are operating effectively and providing adequate protection for the information assets. Continuous monitoring can also help to identify control gaps, ensure system availability, and support compliance requirements, but these are secondary benefits12 References = 1: SP 800-137, Information Security Continuous Monitoring (ISCM) for Federal Information Systems and Organizations, page 1-12: A Practical Approach to Continuous Control Monitoring, ISACA Journal, Volume 2, 2015, page 1.

 Wiping the device remotely is the best option to minimize the risk of data exposure from a stolen personal mobile device. This action will erase all the data stored on the device, including the sensitive corporate data, and prevent unauthorized access or misuse. Wiping the device remotely can be done using enterprise mobility management (EMM) or mobile device management (MDM) tools that allow administrators to remotely manage and secure mobile devices. Alternatively, some mobile devices have built-in features that allow users to wipe their own devices remotely using another device or a web portal.

Preventing the user from using personal mobile devices is not a feasible option, as it may affect the user’s productivity and convenience. Moreover, this option does not address the immediate risk of data exposure from the stolen device.

Reporting the incident to the police is a good practice, but it does not guarantee that the device will be recovered or that the data will be protected. The police may not have the resources or the authority to track down the device or access it.

Removing the user’s access to corporate data is a preventive measure that can limit the damage caused by a stolen device, but it does not eliminate the risk of data exposure from the data already stored on the device. The user may have cached or downloaded data that can still be accessed by an attacker even if the user’s access is revoked. References =

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.
