How do I view the version of the virus library?
The update time of the virus library that is displayed in the Security Center console indicates the version of the virus library. In the Security defense section on the Overview tab, you can view the update time of the virus library to the right of Anti-Virus Version. Security Center dynamically updates the virus library and the characteristics of viruses in the virus library based on the analysis results of specific engines. The engines include lexical analysis engines, virus detection engines, machine learning engines, deep learning engines, big data-based threat detection engines, threat intelligence engines, and abnormal behavior analysis engines. We recommend that you use Security Center to detect vulnerabilities and viruses on a regular basis to protect your servers from the latest viruses. For more information, see Use the quick scan feature.

After I install the Security Center agent on my Elastic Compute Service (ECS) instances, will the virus library of Security Center be installed on the instances?
No,
after you install the Security Center agent on ECS instances, Security Center does not install the virus library on your instances or download the virus library to your instances. The virus library is stored on and is updated by the server of Security Center. The server of Security Center updates the virus library in real time. Security Center checks whether your servers are exposed to viruses based on the virus library.
What are the priorities to handle security events that I can access in the Secure Score section?
Priority | Event handling |
---|---|
1 | Configure or enable core features.
|
2 | Handle AccessKey pair leaks. |
3 | Handle configuration risks in cloud services. |
4 | Handle baseline risks. |
5 | Handle security alerts. |
6 | Fix vulnerabilities. |
What are the differences of the deduction items in the Advanced edition and in the Enterprise, Ultimate, Basic, and Anti-virus editions?
The Basic, Anti-virus, and Advanced editions of Security Center do not support the attack awareness feature. Therefore, this feature is not covered in the scope of security score.
How do I enable the feature of protection against brute-force attacks?
The feature of protection against brute-force attacks blocks malicious IP addresses that attempt to log on to your servers. This improves the security score of your assets. We recommend that you enable this feature. For more information, see FAQ.
How do I handle common alerts?
Security Center allows you to handle alerts detected on your assets. This way, you can reinforce your asset security and increase the security score. For more information, see FAQ.
