What alerts may indicate a compromised endpoint in Sophos?

Unusual behavior alerts, policy violations, and threat detection alerts are critical indicators of a compromised endpoint in Sophos. These alerts typically arise when the behavioral analytics of the endpoint system detect anomalies that deviate from established patterns of usage. For instance, if a known application begins accessing files it normally does not interact with, or if user behavior dramatically shifts in a short period of time, Sophos would generate an unusual behavior alert.

In addition, policy violations can suggest that endpoint security protocols are being circumvented, a common tactic employed by attackers looking to exploit the system. Threat detection alerts are also essential, as they inform administrators of malware or other types of threats that have been identified on the endpoint, indicating a potential compromise that requires immediate investigation.

These alerts collectively provide a comprehensive view of the endpoint's security posture, making them essential for identifying and responding to potential threats promptly. In contrast, software update notifications are routine and do not necessarily indicate security issues, login failures may point to other problems such as user issues rather than a compromise, and network downtime alerts are often related to infrastructure problems rather than direct security threats.
