After security protection is enabled, the system scans for security alert events in your cloud desktops, including suspicious processes, webshells, suspicious logons, and malicious processes. This topic describes how to handle security alerts.
Security alert events are threats detected by the system in cloud desktops. The threats may be attacks from malicious IP addresses or invasions to the cloud desktops, such as executions of malicious scripts in the cloud desktops or access to malicious download sources.
- Emergency: high-risk alerts. If high-risk alerts are generated, intrusion events such as reverse shells are detected in your cloud desktop. We recommend that you review the alert details and handle the alerts in a timely manner.
- Suspicious: medium-risk alerts. If medium-risk alerts are generated, exceptions such as suspicious command sequences are detected in your cloud desktop. We recommend that you review the alert details, check whether your cloud desktop is at risk, and handle the alerts.
- Reminder: low-risk alerts. If low-risk alerts are generated, low-risk exceptions such as suspicious port listening are detected in your cloud desktop. We recommend that you review the alert details in a timely manner.
