In ACE Security Training, what is a basic best practice for information security?

• A. To maximize data collection for marketing.
• B. To train for physical fencing.
• C. To protect confidential information; practice: unique passwords, lock devices, and avoid sharing credentials.
• D. To encourage sharing credentials.

Answer: (C)

Protecting confidential information through good credential hygiene and device security is a fundamental information security habit. Using unique passwords for each account reduces the risk that a single compromised password grants access to many systems. Locking devices when not in use prevents unauthorized access if a device is lost or left unattended. And never sharing credentials preserves accountability and avoids enabling others to act under your identity. The other options miss the security focus: maximizing data collection for marketing isn’t about safeguarding information; training for physical fencing relates to physical barriers rather than digital access; and encouraging sharing credentials directly weakens security.
