 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.

The most important factor to obtain senior leadership support when presenting an information security strategy is that the strategy aligns with management’s acceptable level of risk because it ensures that the strategy is consistent and compatible with the organization’s risk appetite and thresholds, and reflects management’s expectations and priorities for security risk management. The strategy addresses ineffective information security controls is not a very important factor because it does not indicate how the strategy will improve or enhance the security controls or performance. The strategy aligns with industry benchmarks and standards is not a very important factor because it does not indicate how the strategy will differentiate or innovate the organization’s security capabilities or practices. The strategy addresses organizational maturity and the threat environment is not a very important factor because it does not indicate how the strategy will advance or adapt the organization’s security posture or resilience.

According to the CISM Review Manual (Digital Version), page 212, the incident response process consists of six phases: preparation, identification, containment, eradication, recovery, and lessons learned. Containment is the phase where the incident response team isolates the affected systems or networks to prevent further damage or spread of the malware. Eradication is the phase where the incident response team removes the malware and any traces of its activity from the affected systems or networks. Recovery is the phase where the incident response team restores the normal operations of the systems or networks. Identification is the phase where the incident response team detects and analyzes the signs of the incident. Therefore, the information security manager should be confident that the malware has not continued to spread at the completion of the containment phase, which is the earliest phase where the incident response team can stop the propagation of the malware. References = 1: CISM Review Manual (Digital Version), page 212

Comprehensive and Detailed Step-by-Step Explanation:

Recovering from ransomware attacks often depends on having a robust data recovery strategy:

A. Automatic quarantine of systems: This can limit the spread of ransomware but does not address recovery.

B. Thorough communication plans: Communication is important during incidents but does not directly mitigate ransomware.

C. Effective backup plans and processes: This is the BEST option because having backups ensures that encrypted data can be restored, minimizing downtime and data loss.

D. Strong password requirements: This helps prevent unauthorized access but is not sufficient to combat ransomware once it has entered the system.
