The best way to enable the effectiveness of an agile project for the rapid development of a new software application is to separate the work into sprints. Sprints are short, time-boxed iterations that deliver a potentially releasable product increment at the end of each sprint. Sprints allow agile teams to work in a flexible and adaptive manner, respond quickly to changing customer needs and feedback, and deliver value faster and more frequently. Sprints also help teams to plan, execute, review, and improve their work in a collaborative and transparent way. Project segments, phases, and milestones are not specific to agile projects and do not necessarily enable the effectiveness of an agile project.Reference:Agile Project Management [What is it & How to Start] - Atlassian,CISA Review Manual (Digital Version).

The best way to ensure that a backup copy is available for restoration of mission critical data after a disaster is to periodically test backups stored in a remote location. Testing backups is essential to verify that the backup copies are valid, complete, and recoverable. Testing backups also helps to identify any issues or errors that may affect the backup process or the restoration of data. Storing backups in a remote location is important to protect the backup copies from physical damage, theft, or unauthorized access that may occur at the primary site. Using an electronic vault for incremental backups, deploying a fully automated backup maintenance system, or using both tape and disk backup systems are not sufficient to ensure that a backup copy is available for restoration of mission critical data after a disaster, as they do not address the need for testing backups or storing them in a remote location.Reference:Backup and Recovery of Data: The Essential Guide | Veritas,The Truth About Data Backup for Mission-Critical Environments - DATAVERSITY.

Integration testing is the best way to ensure that an application is performing according to its specifications, because it tests the interaction and compatibility of different modules or components of the application.Unit testing, pilot testing and system testing are also important, but they do not cover the whole functionality and integration of the application as well as integration testing does.Reference:CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.3

The best evidence that an organization's IT strategy is aligned to its business objectives is that the IT strategy is approved by executive management. This implies that the IT strategy has been reviewed and validated by the senior leaders of the organization, who are responsible for setting and overseeing the business objectives.The IT strategy may be modified in response to organizational change, based on IT operational best practices, or have significant impact on the business strategy, but these are not sufficient indicators of alignment without executive approval.Reference:CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

Network segmentation is the best security measure to reduce the risk of propagation when a cyberattack occurs, because it divides the network into smaller subnetworks that are isolated from each other and have different access controls and security policies. This limits the spread of malicious traffic and prevents attackers from accessing sensitive data or systems in other segments.A perimeter firewall, a data loss prevention (DLP) system, and a web application firewall are also useful security measures, but they do not prevent propagation within the network as effectively as network segmentation does.Reference:CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.3

The most important thing for the company to verify when outsourcing the printing of customer statements is whether the provider's information security controls are aligned with the company's. This is because customer statements contain sensitive personal and financial information that need to be protected from unauthorized access, disclosure, modification or destruction. The provider's information security controls should be consistent with the company's policies, standards and regulations, and should be audited periodically to ensure compliance.The other options are also relevant, but not as critical as information security.Reference:CISA Review Manual (Digital Version)1, Chapter 3, Section 3.2.2

The best way to ensure that potential security issues are considered by the development team as part of incremental changes to agile-developed software is to include a mandatory step to analyze the security impact when making changes. This will help to identify and mitigate any security risks or vulnerabilities that may arise from the changes, and to ensure that the software meets the security requirements and standards.The other options are not as effective, because they either delegate the security analysis to someone outside the development team, rely on post-deployment testing, or focus on documentation rather than analysis.Reference:CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.5

When verifying the accuracy and completeness of migrated data for a new application system replacing a legacy system, it is most effective for an IS auditor to review data analytics findings. Data analytics is a technique that uses software tools and statistical methods to analyze large volumes of data and identify patterns, anomalies, errors or inconsistencies. Data analytics can help to compare the source and target data sets, validate the data quality and integrity, and detect any data loss or corruption during the migration process.The other options are not as effective, because audit trails only record the actions performed on the data, acceptance testing results only verify the functionality of the new system, and rollback plans only provide contingency measures in case of migration failure.Reference:CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.6

The most critical finding that the IS auditor should consider when reviewing processes for importing market price data from external data providers is that the quality of the data is not monitored. This is because market price data is essential for financial transactions, risk management, valuation and reporting, and any errors or inaccuracies in the data can have significant impact on the organization's performance, reputation and compliance. The IS auditor should ensure that the organization has established quality criteria and controls for the imported data, such as validity, completeness, timeliness, consistency and accuracy, and that the data is regularly checked and verified against these criteria.The other findings are also important, but not as critical as data quality.Reference:CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7
