All assets have the Security Center agent installed

securitycenter_all_assets_agent_installed

Severityhigh
by Prowler

Alibaba Cloud Security Center requires an agent to be installed on each endpoint to provide comprehensive endpoint intrusion detection and protection capabilities. The agent enables remote logon detection, webshell detection and removal, anomaly detection of abnormal process behaviors and network connections, and monitoring of changes to key files and suspicious accounts.

Risk

Assets without the Security Center agent installed become blind spots in security monitoring, as they are not protected by endpoint intrusion detection capabilities. This leaves them vulnerable to malware infections, unauthorized access, webshell attacks, and anomalous process execution without any alerts being generated.

Run this check with Prowler CLI

prowler alibabacloud --checks securitycenter_all_assets_agent_installed

Recommendation

Install the Security Center agent on all assets to enable comprehensive endpoint intrusion detection and protection, including webshell detection, anomaly detection, and remote logon monitoring.
