The first step to reduce the likelihood of infection from the attack is to identify systems that are vulnerable to being exploited by the attack. This would help the organization to assess the scope and severity of the risk, and to prioritize the systems that need immediate protection. Identifying systems that are vulnerable to being exploited by the attack would also help the organization to apply the appropriate patches, updates, or configurations to prevent or mitigate the attack, and to isolate or disconnect the systems that are already infected or compromised.

According to the CRISC Review Manual1, control process efficiency is the degree to which a control process achieves its intended objectives with minimum resources, time, and cost. The primary objective for automating controls is to improve control process efficiency, as automation can help to reduce human errors, increase consistency and accuracy, enhance scalability and flexibility, and optimize performance and productivity. Automation can also help to achieve other objectives, such as facilitating continuous control monitoring, complying with functional requirements, and reducing the need for audit reviews, but these are not the primary objective for automating controls.

The person or entity who should be primarily responsible for performing user entitlement reviews is the data owner. A user entitlement review is a process that verifies and validates the access rights and privileges of the users to the data and resources in the IT environment. A user entitlement review helps to ensure that the users have the appropriate and necessary access to perform their roles and functions, and to prevent or detect any unauthorized or inappropriate access. A data owner is the person or entity that has the authority and responsibility to define, classify, and protect the data and resources in the IT environment. A data owner helps to perform user entitlement reviews, because they help to establish and enforce the access policies and standards for the data and resources, and to approve or revoke the access requests and changes for the users. A data owner also helps to monitor and report on the access performance and compliance for the data and resources, and to identify and address any issues or gaps in the access management activities. The other options are not the primary responsible party for performing user entitlement reviews, although they may be involved in the process. IT security manager, IT personnel, and data custodian are all examples of roles or functions that can help to support or implement the user entitlement reviews, but they do not necessarily have the authority or responsibility to define, classify, or protect the data and resources.

IT asset inventory is the process of tracking and managing the financial, physical, licensing, and contractual aspects of IT assets throughout their life cycle1. IT assets include hardware, software, and network components that an organization values and uses to achieve its objectives2. A complete and accurate IT asset inventory can help an organization to optimize its IT budget, reduce security risks, ensure compliance, and improve performance3.
One of the best controls to enable an organization to ensure a complete and accurate IT asset inventory is performing network scanning for unknown devices. Network scanning is the process of identifying and collecting information about the devices connected to a network, such as their IP addresses, operating systems, open ports, services, and vulnerabilities4. Network scanning can help an organization to:
* Discover and inventory all the IT assets on the network, including those that are unauthorized, unmanaged, or hidden
* Detect and remove any rogue or malicious devices that may pose a threat to the network security or performance
* Update and verify the asset inventory data regularly and automatically, and alert on any changes or discrepancies
* Support the asset lifecycle management and maintenance activities, such as patching, upgrading, or retiring assets5 References = IT Asset Valuation, Risk Assessment and Control Implementation Model, ITAM: The ultimate guide to IT asset management, Navigating Security Threats with IT Inventory Management, Network Scanning - Wikipedia, 8 Best IT Asset Management Software (2024)

The primary responsibility of senior management in risk management is to prioritize the risk scenarios based on severity. Risk scenarios are hypothetical events or situations that could affect the achievement of the objectives. Risk severity is a measure of the overall level of risk, based on the combination of the probability and impact of the risk scenario. Prioritizing the risk scenarios based on severity is the primary responsibility of senior management, because it helps to allocate the resources and actions to the most critical and urgent risks, and to align the risk management process with the organizational strategy and risk appetite. Senior management also has the authority and accountability to make the final decisions and approve the risk response plans for the prioritized risks. The other options are not the primary responsibility of senior management, although they may be involved or consulted in these activities. Bottom-up identification of emerging risks is a process of identifying and reporting the new or changing risks that may arise from the operational or tactical level of the organization. This is usually the responsibility of the risk owners or the risk practitioners, who have the knowledge and experience of the specific functions and processes. Categorization of risk scenarios against a standard taxonomy is a process of classifying and organizing the risk scenarios into predefined categories or groups, based on their nature, source, or impact. This is usually the responsibility of the risk analysts or the risk coordinators, who have the skills and tools to perform the risk analysis and assessment. Review of external loss data is a process of collecting and analyzing the data and information on the losses or incidents that occurred in other organizations or industries, due to similar or related risks. This is usually the responsibility of the risk researchers or the risk consultants, who have the access and expertise to obtain and interpret the external data and information.
