Security Center is a unified security management system that provides real-time identification,
analysis, and notifications about security threats on your system. It provides security
capabilities such as ransomware prevention, anti-virus protection, web tamper prevention,
and compliance assessments. These capabilities help you automate threat detection
and responses, trace secure cloud and on-premises servers, and meet regulatory compliance
requirements. By default, the features of Security Center Basic Edition are enabled
to protect Elastic Compute Service (ECS) instances.
Security Center of the Basic Anti-virus Edition or higher automatically quarantines viruses. It prevents and quarantines common ransomware
(such as WannaCry and Globelmposter) and DDoS Trojans (such as XOR DDoS and BillGates).
We recommend that you use Security Center to improve the security of your assets.
For information about how to enable automatic quarantine, see Use proactive defense.
For more information about the features of each edition, see Features.
