Isaca CRISC Dumps Questions Answers

A threat risk assessment will best quantify the risk associated with malicious users in an organization, because it focuses on identifying and evaluating the potential sources of harm or damage to the organization’s assets, such as data, systems, or networks. A malicious user is a person who intentionally and unauthorizedly accesses, modifies, destroys, or steals the organization’s information or resources, for personal gain, revenge, espionage, or sabotage. A threat risk assessment can help the organization to estimate the likelihood and impact of malicious user attacks, based on factors such as the user’s motivation, capability, opportunity, and access level. A threat risk assessment can also help the organization to determine the appropriate risk response strategies, such as prevention, detection, mitigation, or transfer, to reduce the risk exposure and impact of malicious user attacks. References = Risk IT Framework, ISACA, 2022, p. 141

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 of the 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, and consistency9 . 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 =

When using a third party to perform penetration testing, the most important control to minimize operational impact is to clearly define the project scope. This means specifying the objectives, boundaries, methods, and deliverables of the testing, as well as the roles and responsibilities of the parties involved. A clear project scope helps to avoid misunderstandings, conflicts, and disruptions that could compromise the security, availability, or integrity of the systems under test. It also helps to ensure that the testing is aligned with the organization’s risk appetite and compliance requirements. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.2.3.2, Page 137.
