What is a common sign of a data breach?

• A. An increase in software updates
• B. Unusual account activity or login attempts
• C. An improvement in network speed
• D. Enhanced encryption software usage

Answer: (B)

A common sign of a data breach is unusual account activity or login attempts. When a breach occurs, unauthorized individuals may attempt to access accounts, leading to unexpected activities such as logins from unfamiliar locations, multiple failed login attempts, or account changes that users did not initiate. This erratic behavior is a clear indicator that something may be wrong, as it deviates from normal operational patterns and user behavior.

In contrast, an increase in software updates generally reflects a proactive approach to security and maintenance, aimed at addressing vulnerabilities and improving performance. Similarly, an improvement in network speed is typically associated with better network management or upgrades rather than a sign of a breach. Lastly, enhanced encryption software usage is a security measure that helps protect data but does not directly indicate a breach has occurred; rather, it aims to prevent unauthorized access.
