Comprehensive and Detailed Explanation From Exact Extract:

The Recovery Time Objective (RTO) defines the maximum acceptable downtime for a business function or system following a disruption. If the organization requires recovery in 30 minutes, that is the system’s RTO.

This metric guides the selection of technologies, staffing, and procedures needed to meet recovery expectations.

“RTO defines the target time set for the recovery of IT and business activities after a disruption. It is a key BCP design parameter.”

The most concerning issue for the information security steering committee should be that no owners were identified for some risks in the risk register. This means that there is no clear accountability and responsibility for managing and mitigating those risks, and that the risks may not be properly addressed or monitored. The risk owners are the persons who have the authority and ability to implement the risk treatment options and to accept the residual risk. The risk owners should be identified and assigned for each risk in the risk register, and they should report the status and progress of the risk management activities to the information security steering committee.

The primary reason for creating a business case when proposing an information security project is to establish the value of the project in relation to the business objectives and to justify the investment required. A business case should demonstrate how the project aligns with the organization’s strategy, goals, and mission, and how it supports the business processes and functions. A business case should also include the expected benefits, costs, risks, and alternatives of the project, and provide a clear rationale for choosing the preferred option.

The results of a risk assessment would best enable an informed decision by senior management when developing a business case to justify an information security investment. A risk assessment will help to identify and prioritize the threats and vulnerabilities that affect the organization’s assets and processes, as well as the potential impact and likelihood of occurrence. A risk assessment will also provide a basis for selecting and evaluating the effectiveness of controls to mitigate the risks. According to CISA, developing a business case for security will be based on an in-depth understanding of organizational vulnerabilities, operational priorities, and return on investment1. The information security strategy, losses due to security incidents, and security investment trends in the industry are possible inputs or outputs of a risk assessment, but they are not sufficient to enable an informed decision by senior management.
