Canadian Imperial Bank Of Commerce (CIBC) Interview Practice Test

When sharing confidential information, you want channels that limit who can access the content and protect it both in transit and at rest. A public chat channel is least appropriate because it’s designed for broad, informal communication and is typically accessible to many people, potentially including those who don’t need to know the information. Messages in a public chat can be seen, forwarded, screenshotted, or archived, increasing the risk of exposure and data leakage. By contrast, secure encrypted email protects content with encryption and controls who can read it, making misdelivery less likely. Secure file transfer adds encryption and access controls for transferring files, ensuring only authorized recipients can retrieve the data. In-person handover with authorization provides a direct, controlled transfer where identity and access can be verified, minimizing digital exposure. So, the channel that compromises confidentiality the most is the public chat channel due to its broad visibility and weaker safeguards.
