The application protection feature adopts the Runtime Application Self Protection (RASP) technology to detect attacks during application runtime, and then block the attacks or generate alerts for the attacks. This helps protect applications. You can use this feature after you purchase a Quota for Application Protection. For more information, see Application protection.

Container Protection Settings

Threat Detection on Kubernetes Containers

Security Center monitors the status of running containers in a Kubernetes cluster. This allows you to detect security risks and attacker intrusions at the earliest opportunity. Security Center detects the following items:

  • Suspicious instruction execution on a Kubernetes API server

  • Mounting of suspicious directories to a pod

  • Lateral movement among Kubernetes service accounts

  • Startup of a pod that contains a malicious image

Value-added features

The global log filtering feature ensures security, maximizes log storage usage, and improves your operational efficiency. If you use the Anti-virus edition of Security Center or higher, you can use this feature after you purchase the log storage capacity for log analysis and enable the log analysis feature. For more information, see Global log filtering.

Limits on threat detection

Security Center sends alerts in real time when risks are detected. You can manage security alerts, scan for and fix vulnerabilities, analyze attacks, and perform configuration assessment in the Security Center console. Security Center can analyze alerts and trace attacks. This reinforces the security of your assets. To protect your assets against attacks, we recommend that you regularly install the latest security patches on your server, and use other security services together with Security Center, such as Cloud Firewall and Web Application Firewall (WAF).

After you install the Security Center agent on a server, the defense process of Security Center requires a specific period of time to take effect on the server. During this period of time, Security Center cannot block threats such as ransomware and DDoS trojans.

Important

Attacks and viruses are always changing, and actual workloads run in different environments. Therefore, Security Center cannot ensure that all unknown threats are detected in real time. We recommend that you use Security Center features such as alerting, vulnerability detection, baseline check, and configuration assessment to enhance security and prevent intrusions, data thefts, and data damage.
