IT performance measures are indicators of how well an organization is achieving its IT goals and objectives.
Benchmarking surveys are useful tools for comparing an organization's IT performance measures with those of other organizations in the same industry or sector. Benchmarking surveys can provide insights into best practices, gaps, trends, and opportunities for improvement. IT governance frameworks, utilization reports, and balanced scorecards are not as helpful for comparing ITperformance measures across organizations, as they may vary in scope, methodology, and terminology.

The best option to support the organization's objectives of protecting data confidentiality while transporting data is encryption. Encryption is a process of transforming data into an unreadable form using a secret key or algorithm, so that only authorized parties can access the original data. Encryption protects the confidentiality of data in transit by preventing unauthorized interception,modification, or disclosure of the data. Encryption can also help comply with data privacy and security regulations, such as the GDPR and HIPAA.
The other options are not as effective as encryption in protecting data confidentiality while transporting data.
Cryptographic hashes are mathematical functions that generate a fixed-length output from an input, but they do not encrypt the data. Hashes are used to verify the integrity and authenticity of data, but they do not prevent unauthorized access to the data. Virtual local area network (VLAN) is a logical grouping of network devices that share the same broadcast domain, but they do not encrypt the data. VLANs can improve network performance and security by isolating traffic, but they do not protect the data from being intercepted or modified by external attackers. Dedicated lines are physical connections that provide exclusive access to a network or service, but they do not encrypt the data. Dedicated lines can offer higher bandwidth and reliability, but they do not guarantee the confidentiality of the data from being compromised by physical tampering or eavesdropping.

The greatest concern for an IS auditor reviewing a network printer disposal process is that evidence is not available to verify printer hard drives have been sanitized prior to disposal. This can expose sensitive data to unauthorized parties and cause data breaches. Disposal policies and procedures not being consistently implemented or business units being allowed to dispose printers directly to vendors are compliance issues, but not as critical as data protection. Inoperable printers being stored in an unsecured area is a physical security issue, but not as severe as data leakage. References: ISACA, CISA Review Manual, 27th Edition, 2018, page

Among the options provided, fingerprint scanning has the highest rate of false negatives. False negatives occur when a biometric system fails to recognize an authentic individual. Factors such as skin conditions (wet, dry, greasy), finger injuries, and inadequate scanning can contribute to false negatives in fingerprint scanning1. In comparison, iris recognition23, face recognition45, and retina scanning67 generally have lower rates of false negatives.
