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.Reference:CISA Review Manual, 27th Edition, page 361

One benefit of return on investment (ROI) analysis in IT decision making is that it provides the basis for allocating financial resources. ROI analysis is a method of evaluating the profitability or cost-effectiveness of an IT project or investment by comparing the expected benefits with the required costs. ROI analysis can help IT decision makers prioritize and justify their IT initiatives, allocate their financial resources optimally, and demonstrate the value contribution of IT to the organization's goals and objectives. Basis for allocating indirect costs, cost of replacing equipment, and estimated cost of ownership are not benefits of ROI analysis in IT decision making. These are more inputs or outputs of ROI analysis that could be used to calculate or estimate the costs or benefits of an IT project or investment.Reference: [ISACA CISA Review Manual 27th Edition], page 307

The finding that should be ranked as the highest risk is that network penetration tests are not performed. Network penetration tests are simulated cyberattacks that aim to identify and exploit the vulnerabilities and weaknesses of the network security controls, such as firewalls, routers, switches, servers, and devices. Network penetration tests are essential for assessing the effectiveness and resilience of the network security posture, and for providing recommendations for improvement and remediation. If network penetration tests are not performed, the organization may not be aware of the existing or potential threats and risks to its network, and may not be able to prevent or respond to real cyberattacks, which can result in data breaches, service disruptions, financial losses, reputational damage, and legal or regulatory penalties.The other findings are also important, butnot as risky as the lack of network penetration tests, because they either do not directly affect the networksecurity controls, or they can be addressed by documentation or approval processes.Reference:CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4
