Unauthorized modification of data by a database administrator is a security risk that involves altering, deleting, or inserting data on a database without proper authorization or approval, by a person who has privileged access to the database, such as a database administrator12.

The best control to detect unauthorized modification of data by a database administrator is to review database activity logs, which are records that capture and store the details and history ofthe transactions or activities that are performed on the database, such as who, what, when, where, and how34.

Reviewing database activity logs is the best control because it provides evidence and visibility of the database operations, and enables the detection and reporting of any deviations, anomalies, or issues that may indicate unauthorized modification of data by a database administrator34.

Reviewing database activity logs is also the best control because it supports the accountability and auditability of the database operations, and facilitates the investigation and resolution of any unauthorized modification of data by a database administrator34.

The other options are not the best controls, but rather possible measures or techniques that may supplement or enhance the review of database activity logs. For example:

Reviewing database access rights is a measure that involves verifying and validating the permissions and privileges that are granted or revoked to the users or roles who can access or modify the data on the database56. However, this measure is not the best control because it does not directly detect unauthorized modification of data by a database administrator, especially if the database administrator has legitimate access rights to the data56.

Comparing data to input records is a technique that involves matching and reconciling the data on the database with the original or source data that are entered or imported into the database, and identifying and correcting any discrepancies or errors78. However, this technique is not the best control because it does not directly detect unauthorized modification of data by a database administrator, especially if the input records are also modified or compromised78.

Reviewing changes to edit checks is a technique that involves examining and evaluating the modifications or updates to the edit checks, which are rules or validations that are applied to the data on the database to ensure their accuracy, completeness, andconsistency9 . However, this technique is not the best control because it does not directly detect unauthorized modification of data by a database administrator, especially if the edit checks are bypassed or disabled9 . References =

A technical vulnerability is a weakness or flaw in the design or implementation of an information system or resource that can be exploited or compromised by a threat or source of harm that may affect the organization’s objectives or operations. A technical vulnerability may be caused byvarious factors, such as human error, system failure, process inefficiency, resource limitation, etc.

A vulnerability assessment is a process of identifying and evaluating the technical vulnerabilities that exist or may arise in the organization’s information systems or resources, and determining their severity and impact. A vulnerability assessment can help the organization to assess and prioritize the risks, and to design and implement appropriate controls or countermeasures to mitigate or prevent the risks.

The best response to the scenario of a recently discovered technical vulnerability being actively exploited is to conduct a vulnerability assessment, because it can help the organization to address the following questions:

What is the nature and extent of the technical vulnerability, and how does it affect the functionality or security of the information system or resource?

How is the technical vulnerability being exploited or compromised, and by whom or what?

What are the potential consequences or impacts of the exploitation or compromise of the technical vulnerability for the organization and its stakeholders?

How can the technical vulnerability be detected and reported, and what are the available or feasible options or solutions to address or correct it?

Conducting a vulnerability assessment can help the organization to improve and optimize the information system or resource quality and performance, and to reduce or eliminate the technical vulnerability. It can also help the organization to align the information system or resource with the organization’s objectives and requirements, and to comply with the organization’s policies and standards.

The other options are not the best responses to the scenario of a recently discovered technical vulnerability being actively exploited, because they do not address the main purpose and benefit of conducting a vulnerability assessment, which is to identify and evaluate the technical vulnerability, and to determine its severity and impact.

Assessing the vulnerability management process is a process of evaluating and verifying the adequacy and effectiveness of the process that is used to identify, analyze, evaluate, and communicate the technical vulnerabilities, and to align them with the organization’s objectives and requirements. Assessing the vulnerability management process can help the organization to improve and optimize the process, and to reduce or eliminate the gaps or weaknesses in the process, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.

Conducting a control self-assessment is a process of evaluating and verifying the adequacy and effectiveness of the controls that are intended to ensure the confidentiality, integrity, availability, and reliability of the information systems and resources, using the input and feedback from the individuals or groups that are involved or responsible for the information systems activities or functions. Conducting a control self-assessment can help the organization to identify and document the control deficiencies, and to align them with the organization’s objectives and requirements, but it is not the best response to the scenario, because it does not indicate thenature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.

Reassessing the inherent risk of the target is a process of reevaluating and recalculating the amount and type of risk that exists in the absence of any controls, and that is inherent to the nature or characteristics of the target, which is the information system or resource that is affected by the technical vulnerability. Reassessing the inherent risk of the target can help the organization to understand and document the risk exposure or level, and to align it with the organization’s risk appetite and tolerance, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders. References =

Cyber risk insurance is a type of insurance policy that provides coverage against losses and damages caused by cyber incidents such as data breaches, hacking, and other cyber attacks. When an organization decides to purchase cyber risk insurance, it transfers the risk of financial loss due to a cyber incident to the insurance company. In the scenario described in the question, the organization allowed its cyber risk insurance to lapse while seeking a new insurance provider. This means that the organization is currently not covered by any cyber risk insurance policy and is therefore exposed to financial losses due to cyber incidents. The risk practitioner should report to management that the risk has been accepted. Accepting risk means that the organization is aware of the potential consequences of the risk and has decided not to take any action to mitigate, transfer, or avoid it. The other options are not correct because they do not reflect the current situation of the organization. The organization has not transferred the risk to another party, as it has no cyber risk insurance policy in place. The organization has not mitigated the risk, as it has not implemented anycontrols or measures to reduce the likelihood or impact of the risk. The organization has not avoided the risk, as it has not eliminated the source or cause of the risk or changed its activities to prevent the risk from occurring. References = CRISC Review Manual, pages 32-331; CRISC Review Questions, Answers & Explanations Manual, page 752

The main reason for documenting the performance of controls is to provide accurate risk reporting. Risk reporting is a process that communicates and discloses the relevant and reliable information about the risks and their management to the stakeholders and decision makers. Risk reporting is an essential component of the risk management process, as it helps to monitor and evaluate the effectiveness and efficiency of the risk identification, assessment, response, and monitoring activities, as well as to support and inform the risk governance and oversight functions. Documenting the performance of controls is a technique that records and tracks the results and outcomes of the controls that are implemented to address the risks, such as the control objectives,
