The first thing that an information security manager should do upon confirming a privileged user's unauthorized modifications to a security application is to enforce the security configuration and require the change to be reverted. This is because the unauthorized modification may have compromised the security of the application and the data it protects, and may have violated the security policies and standards of the organization. By enforcing the security configuration and requiring the change to be reverted, the information security manager can restore the security posture of the application and prevent further unauthorized modifications.

The most important outcome of effective risk treatment is the implementation of corrective actions that address the root causes of the risk and reduce its likelihood and/or impact to an acceptable level. Effective risk treatment does not necessarily eliminate the risk, but rather brings it within the organization's risk appetite and tolerance. Timely reporting of incidents and reduced cost of acquiring controls are desirable benefits of effective risk treatment, but they are not the primary outcome.

A SIEM system is the best tool for providing an incident response team with the greatest insight into insider threat activity across multiple systems because it can collect, correlate, analyze, and report on security events and logs from various sources, such as network devices, servers, applications, and user activities. A SIEM system can also detect and alert on anomalous or suspicious behaviors, such as unauthorized access, data exfiltration, privilege escalation, or policy violations, that may indicate an insider threat. A SIEM system can also support forensic investigations and incident response actions by providing a centralized and comprehensive view of the security posture and incidents.

Conducting periodic user awareness training is the best way to mitigate accidental data loss events because it can educate the users on the causes, consequences, and prevention of data loss, and increase their awareness of the security policies and procedures of the organization. User awareness training can also help users to identify and report potential data loss incidents, and to adopt good practices such as backing up data, encrypting data, and using secure channels for data transmission and storage.

The primary reason to assign a risk owner in an organization is to ensure accountability for the risk and its treatment. A risk owner is a person or entity that has the authority and responsibility to manage a specific risk and to implement the appropriate risk response actions. By assigning a risk owner, the organization can ensure that the risk is monitored, reported, and controlled in accordance with the organization's risk appetite and tolerance.

Conducting periodic testing is the best way to ensure the BCP is current because it can validate the effectiveness and efficiency of the BCP, identify any gaps or weaknesses, and provide feedback and recommendations for improvement. Testing can also verify that the BCP reflects the current business environment, processes, and requirements, and that the BCP team members are familiar with their roles and responsibilities.

The first thing that the information security manager should do after reading about a vendor product compromise on social media is to validate the risk to the organization. This means verifying the source and credibility of the information, determining if the organization uses the affected product, and assessing the potential impact and likelihood of the compromise on the organization's data and systems. Validating the risk to the organization will help the information security manager to decide on the appropriate course of action, such as activating the incident response program, notifying relevant stakeholders, or performing a BIA.

When integrating security risk management into an organization, it is most important to ensure that the risk management methodology follows an established framework, such as ISO 31000, NIST SP 800-30, or COBIT. This is because a framework provides a consistent and structured approach to identify, assess, treat, and monitor risks, and to align the risk management process with the organization's objectives, culture, and governance. A framework also helps to ensure compliance with relevant standards and regulations, and to facilitate communication and reporting of risks to stakeholders.
