= Information security governance is the process of establishing and maintaining the policies, standards, frameworks, and best practices that guide the information security program of an organization. Information security governance helps to ensure that the information security program meets the needs of the business by aligning it with the organization's risk appetite, objectives, and strategy. Information security governance also helps to coordinate and integrate various assurance functions, such as risk management, compliance, audit, and incident response, to provide a holistic view of the information security posture. Information security governance is essential for achieving a positive return on investment (ROI) from information security investments, as well as for enhancing the trust and confidence of internal and external stakeholders.

Information security governance is MOST important to have in place to help ensure an organization's cybersecurity program meets the needs of the business. This is because information security governance provides the strategic direction, oversight and accountability for the cybersecurity program. It also ensures that the program aligns with the business objectives, risk appetite and compliance requirements of the organization. Information security governance involves defining roles and responsibilities, establishing policies and standards, setting goals and metrics, allocating resources and monitoring performance of the cybersecurity program.

Incident impact is the primary factor for classification and categorization. It ensures incidents are addressed based on their potential to disrupt the organization.
"Incident impact should be the primary factor in defining categorization levels to ensure appropriate prioritization and response."
- CISM Review Manual 15th Edition, Chapter 4: Incident Management, Section: Incident Classification and Prioritization* ISACA practice database stresses that focusing on impact ensures incidents receive the proper response priority.

A business-aligned information security program is one that supports the organization's business objectives and aligns the information security strategy with the business functions. A business impact analysis (BIA) is a process that identifies the critical business processes, assets, and functions of an organization, and assesses their potential impact in the event of a disruption or loss. A BIA helps to prioritize the information security requirements and controls that are needed to protect the organization's critical assets and functions from various threats and risks. Therefore, a BIA is one of the most useful sources when planning a business-aligned information security program.

The most useful source when planning a business-aligned information security program is a Business Impact Analysis (BIA). A BIA is a process of identifying and evaluating the potential effects of disruptions to an organization's operations, and helps to identify the security controls and measures that should be implemented to reduce the impact of those disruptions. The BIA should include an assessment of the organization's information security posture, including its security policies, risk register, and enterprise architecture. With this information, organizations can develop an information security program that is aligned to the organization's business objectives.

= The information security manager should contact the information owner after the incident has been confirmed, as this is the first step of the incident response process. The information owner is the person who has the authority and responsibility for the information asset that is affected by the incident. The information owner needs to be informed of the incident as soon as possible, as they may have to make decisions or take actions regarding the protection, recovery, or restoration of the information asset. The information owner may also have to communicate with other stakeholders, such as the business units, customers, regulators, or media, depending on the nature and impact of the incident.
The other options are not the correct time to contact the information owner, as they occur later in the incident response process. Contacting the information owner after the incident has been contained, mitigated, or logged may delay the notification and escalation of the incident, as well as the involvement and collaboration of the information owner. Moreover, contacting the information owner after the incident has been contained or mitigated may imply that the incident response team has already taken actions that may affect the information asset without the consent or approval of the information owner. Contacting the information owner after a potential incident has been logged may cause unnecessary alarm or confusion, as the potential incident may not be a real or significant incident, or it may not affect the information owner's asset.
