Moving validation controls from the server side into the browser would most likely increase the risk of a successful attack by structured query language (SQL) injection. SQL injection is a technique that exploits a security vulnerability in an application’s database layer by inserting malicious SQL statements into user input fields. Validation controls are used to check and filter user input before sending it to the database. If these controls are moved to the browser, they can be easily bypassed or modified by an attacker, who can then execute arbitrary SQL commands on the database. References: CISA Review Manual, 27th Edition, page 361

The most important control to assess in an audit of an organization’s accounts payable processes is segregation of duties between issuing purchase orders and making payments. Segregation of duties is a principle that requires different individuals or departments to perform different tasks or functions within a process, in order to prevent fraud, errors, or conflicts of interest. In the accounts payable process, segregation of duties between issuing purchase orders and making payments ensures that no one person can initiate and complete a transaction without proper authorization and verification. This reduces the risk of duplicate payments, overpayments, unauthorized payments, or payments to fictitious vendors.

The most concerning issue when determining if information assets are adequately safeguarded during transport and disposal is lack of appropriate data classification. Data classification is a process that assigns categories or levels of sensitivity to different types of information assets based on their value, criticality, or risk to the organization. Data classification can help safeguard information assets during transport and disposal by providing criteria and guidelines for identifying, labeling, handling, and protecting information assets according to their sensitivity. Lack of appropriate data classification can compromise the security and confidentiality of information assets during transport and disposal by exposing them to unauthorized access, disclosure, theft, damage, or destruction. The other options are not as concerning as lack of appropriate data classification in safeguarding information assets during transport and disposal, as they do not affect the identification, labeling, handling, or protection of information assets according to their sensitivity. Lack of appropriate labeling is a possible factor that may increase the risk of misplacing, losing, or mishandling information assets during transport and disposal, but it does not affect the classification of information assets according to their sensitivity. Lack of recent awareness training is a possible factor that may affect the knowledge or behavior of staff involved in transporting or disposing of information assets, but it does not affect the classification of information assets according to their sensitivity. Lack of password protection is a possible factor that may affect the security or confidentiality of information assets stored on devices during transport and disposal, but it does not affect the classification of information assets according to their sensitivity. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.2

The first step when planning a penetration test is to obtain management consent for the testing. This is because a penetration test involves simulating a cyberattack against theorganization’s systems and networks, which may have legal, ethical, and operational implications. Without proper authorization from management, a penetration test may violate laws, policies, contracts, or service level agreements. Management consent also helps define the objectives, scope, and boundaries of the test, as well as the roles and responsibilities of the testers and the stakeholders. Obtaining management consent for the testing also demonstrates due care and due diligence on the part of the testers and the organization.

Executing nondisclosure agreements (NDAs), determining reporting requirements for vulnerabilities, and defining the testing scope are important steps when planning a penetration test, but they are not the first step. These steps should be done after obtaining management consent for the testing, as they depend on the approval and involvement of management and other parties.
