The principle that John violated by accessing Abey's confidential information is confidentiality. Confidentiality is a crucial aspect of information assurance that ensures sensitive information is accessible only to those who are authorized to view it. By accessing confidential information without permission, John breached the trust and security measures that are in place to protect Abey's data.

This principle is essential in maintaining privacy and protecting personal or sensitive information from unauthorized access, which can lead to misuse or harm. Violating confidentiality undermines the foundational trust required in handling sensitive data within any information security framework.

Understanding the importance of confidentiality helps organizations implement proper access controls and data protection measures to safeguard against unauthorized access, thereby reinforcing the integrity and trustworthiness of the information system.
