 Periodically reviewing log files is the most effective way to detect intrusion attempts from outside the organization, as they can provide evidence of unauthorized access attempts, source IP addresses, timestamps and other relevant information. Using smart cards with one-time passwords or installing biometrics-based authentication can prevent unauthorized access, but not detect it. Configuring the router as a firewall can block unwanted traffic, but not log it. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 361

Visualization technology is the use of software and hardware to create graphical representations of data, such as charts, graphs, maps, images, etc. Visualization technology can help users to understand, analyze, and communicate complex and large amounts of data in an intuitive and engaging way1.

One of the primary advantages of using visualization technology for corporate applications is that it can improve the utilization of resources, such as time, money, human capital, and physical assets. Some of the ways that visualization technology can achieve this are:

Visualization technology can help users to quickly and easily explore, filter, and interact with data, reducing the need for manual data processing and analysis1. This can save time and effort for both data producers and consumers, and allow them to focus on more value-added tasks.

Visualization technology can help users to discover patterns, trends, outliers, correlations, and causations in data that may otherwise be hidden or overlooked in traditional reports or tables1. This can enable users to make better and faster decisions based on data-driven insights, and optimize their strategies and actions accordingly.

Visualization technology can help users to communicate and share data more effectively and persuasively with different audiences, such as customers, partners, investors, regulators, etc1. This can enhance the reputation and credibility of the organization, and foster collaboration and innovation among stakeholders.

Visualization technology can help users to monitor and measure the performance and impact of their activities, products, services, or processes1. This can help users to identify problems or opportunities for improvement, and adjust their plans or actions accordingly.

Visualization technology can help users to create engaging and interactive experiences for their customers or end-users1. This can increase customer satisfaction and loyalty, and generate more revenue or value for the organization.

Therefore, using visualization technology for corporate applications can help organizations to better utilize their resources and achieve their goals.

File transfer protocol (FTP) is a service that allows users to transfer files between computers over a network. If enabled within firewall rules, FTP would present the greatest risk, as it can expose sensitive data to unauthorized access, modification, or deletion. FTP does not provide encryption or authentication, which makes it vulnerable to eavesdropping, spoofing, and tampering attacks. Simple mail transfer protocol (SMTP), simple object access protocol (SOAP), and hypertext transfer protocol (HTTP) are also services that can be used to exchange data over a network, but they have more security features than FTP, such as encryption, authentication, or validation. References: CISA Review Manual (Digital Version)

The most significant risk from not testing patches before putting them into production is the lack of system integrity. Patches are software updates that fix bugs, vulnerabilities or performance issues in an application system. However, patches may also introduce new errors, conflicts or compatibility issues that could affect the functionality, reliability or security of the system4. By not testing patches before putting them into production, the organization exposes itself to the risk of system failures, data corruption or unauthorized access. Loss of application support, outdated system documentation and developer access to production are also risks from not testing patches, but they are not as significant as the lack of system integrity. References:
