 A recovery point objective (RPO) is required in a disaster recovery plan (DRP), because it indicates the earliest point in time to which it is acceptable to recover data after a disaster. It effectively quantifies the permissible amount of data loss in case of interruption. It is determined based on the acceptable data loss in case of disruption of operations1. A DRP is a document that defines the procedures, resources, and actions to restore the critical IT systems and data in the event of a disaster that affects the normal operations of the organization2. A DRP should include the RPO for each critical system and data, as well as the backup and restoration methods, frequency, and location to achieve the RPO3.

A RPO is not required in an information security plan, an incident response plan, or a business continuity plan (BCP), because these plans have different purposes and scopes. An information security plan is a document that defines the objectives, policies, standards, and guidelines for information security management in the organization4. An incident response plan is a document that defines the procedures, roles, and responsibilities for identifying, analyzing, responding to, and learning from security incidents that may compromise the confidentiality, integrity, or availability of information assets. A BCP is a document that defines the procedures, resources, and actions to ensure the continuity of the essential business functions and processes in the event of a disruption that affects the normal operations of the organization. These plans may include other metrics, such as recovery time objective (RTO), which is the amount of time after a disaster in which business operation is resumed, or resources are again available for use, but they do not require a RPO.

Entering identified risks into the organization's risk register ensures that they are documented, tracked, assigned, and addressed. Without recording in the risk register, there’s no formal mechanism to manage, treat, or monitor the risk.

“The risk register is the central repository for tracking all known risks, their status, and treatment plans.”

= The most important message to convey to employees in building a security risk-aware culture is that the responsibility for security rests with all employees, not just the information security function or the management. A security risk-aware culture is a collective mindset of the people in the organization working every day to protect the enterprise and its information assets from internal and external threats. A security risk-aware culture requires the workforce to know the security risks and the processes for avoiding or mitigating them, and to make thoughtful decisions that align with security policies and standards. A security risk-aware culture also incorporates a broader corporate culture of day-to-day actions that encourage employees to report security incidents, share security best practices, and participate in security awareness and training programs. A security risk-aware culture helps to reduce the human factor that causes 90 percent of all cyberattacks, and to offset the impact of corrupted or lost data, decreased revenue, regulatory fines, and reputational damage. A security risk-aware culture turns people from assets that must be protected into assets that actively contribute to the cybersecurity and risk management posture and elevate security to being a business enabler rather than a business impediment123.

Personal information requires different security controls than sensitive information is a true statement, but it is not the most important message to convey to employees in building a security risk-aware culture. Personal information is any information that can identify or relate to a natural person, such as name, address, email, phone number, social security number, etc. Sensitive information is any information that is confidential, proprietary, or has a high value or impact to the organization, such as trade secrets, financial data, customer data, intellectual property, etc. Different types of information may have different legal, regulatory, contractual, or ethical obligations to protect them from unauthorized access, use, disclosure, modification, or destruction. Therefore, different security controls may be applied to personal and sensitive information based on their classification, such as encryption, access control, retention, disposal, etc. However, this message does not address the broader concept of security risk-aware culture, which is not limited to information classification and protection, but also encompasses the behaviors, attitudes, and values of the employees towards security.

Employee access should be based on the principle of least privilege is a good practice, but it is not the most important message to convey to employees in building a security risk-aware culture. The principle of least privilege states that users should only have the minimum level of access and permissions that are necessary to perform their job functions, and no more. This principle helps to reduce the risk of unauthorized or inappropriate actions, such as data leakage, fraud, sabotage, etc., by limiting the exposure and impact of user activities. However, this message does not capture the essence of security risk-aware culture, which is not only about access control, but also about the awareness, understanding, and commitment of the employees to security.

Understanding an information asset’s value is critical to risk management is a valid point, but it is not the most important message to convey to employees in building a security risk-aware culture. Understanding an information asset’s value is essential to determine the potential impact and likelihood of a security risk, and to prioritize the appropriate risk response strategies, such as avoidance, mitigation, transfer, or acceptance. However, this message does not reflect the holistic nature of security risk-aware culture, which is not only about risk assessment, but also about risk communication, risk treatment, and risk monitoring. References =

The best option to enable the capability of an organization to sustain the delivery of products and services within acceptable time frames and at predefined capacity during a disruption is B. Business continuity plan (BCP). This is because a BCP is a documented collection of procedures and information that guides the organization to prepare for, respond to, and recover from a disruption, such as a natural disaster, a cyberattack, or a pandemic. A BCP aims to ensure the continuity of the critical business functions and processes that support the delivery of products and services to the customers and stakeholders. A BCP also defines the roles, responsibilities, resources, and actions required to maintain the operational resilience of the organization in the face of a disruption.
