What are common signs of a possible security breach?

Unexplained data loss is a significant indicator of a possible security breach. When sensitive or critical data is missing or has been tampered with, it raises immediate concerns about unauthorized access or malicious activity. Such data loss can result from various forms of cyber incidents, including hacking, insider threats, or exploitation of vulnerabilities within the system. Keeping a vigilant eye on data integrity and ensuring there are systems in place to detect unexpected changes can help organizations identify potential breaches early and respond effectively.

In contrast, the other options—such as increased user engagement, improved system performance, and overall network stability—generally suggest positive user and system conditions rather than indicating security issues. While it is crucial to monitor these factors for signs of unauthorized access or other security concerns, their presence does not typically signify a breach on their own.
