Section: INFORMATION RISK MANAGEMENT
Explanation:
Cost-benefit analysis is performed to ensure that the cost of a safeguard does not outweigh its benefit and that the best safeguard is provided for the cost of implementation. Risk analysis identifies the risks and suggests appropriate mitigation. The annualized loss expectancy (ALE) is a subset of a cost-benefit analysis. Impact analysis would indicate how much could be lost if a specific threat occurred.

Explanation
Information security projects should be assessed on the basis of the positive impact that they will have on the organization. Time, cost and resource issues should be subordinate to this objective.

A compromised endpoint device is a potential threat to the security of the network and the data stored on it.
The best course of action to prevent further damage is to isolate the endpoint device from the network and other devices, so that the attacker cannot access or spread to other systems. Isolating the endpoint device also allows the information security manager to investigate the incident and determine the root cause, the extent of the compromise, and the appropriate remediation steps. Wiping and resetting the endpoint device may not be feasible or desirable, as it may result in data loss or evidence destruction. Powering off the endpoint device may not stop the attack, as the attacker may have installed persistent malware or backdoors that can resume once the device is powered on again. Running a virus scan on the endpoint device may not be effective, as the attacker may have used sophisticated techniques to evade detection or disable the antivirus software.

The best way to reduce the risk associated with a bring your own device (BYOD) program is to implement a mobile device policy and standard. This policy should include guidelines and rules regarding the use of mobile devices, such as acceptable use guidelines and restrictions on the types of data that can be stored or accessed on the device. Additionally, it should also include requirements for secure mobile device practices, such as the use of strong passwords, encryption, and regular patching. A mobile device management (MDM) solution can also be implemented to help ensure mobile devices meet the organizational security requirements. However, it is not enough to simply implement the policy and MDM solution; employees must also be trained on the secure mobile device practices to ensure the policy is followed.

Explanation
An information security governance framework is a set of principles, policies, standards, and processes that guide the development, implementation, and management of an effective information security program that supports the organization's objectives and strategy. The framework provides direction to meet business goals while balancing risks and controls, as it helps to align the information security activities with the business needs, priorities, and risk appetite, and to ensure that the security resources and investments are optimized and justified.
