Alibaba Cloud security experts test and verify all the automatically blocked viruses to minimize false positive rates.
Persistent webshells	Security Center detects persistent webshells on servers. After an attacker gains control over a server, the attacker typically places webshells, such as scripts, processes, and links, to persistently exploit the intrusion. Common persistent webshells include crontab jobs, automatic tasks, and system replacement files.
Threats to web applications	Security Center detects intrusion activities that use web applications.
Malicious script	Security Center detects malicious scripts on servers. Malicious scripts are classified into file-based scripts and fileless scripts. After an attacker gains control over a server, the attacker uses scripts to carry out the actual attack. For example, the attacker may insert mining programs and webshells, and add administrator accounts to your system. Languages of malicious scripts include Bash, Python, Perl, PowerShell, Batch, and VBScript.
Malicious Network Activity	Security Center identifies unusual network behavior based on logs, such as communication content and host behavior logs. Malicious network behavior includes intrusion into hosts over open network services and unusual behavior of cracked hosts.
Threat detection during container runtime	Security Center detects threats to Container Service for Kubernetes in real time. The threats include viruses and malicious programs in containers or on hosts, intrusion into containers, and container escapes. Security Center also generates alerts for these threats and warnings for high-risk operations. Security Center detects the following threats for containers during container runtime and generates alerts for detected threats: Malicious image startups Security Center dynamically monitors open image sources, such as Docker Hub, and generates alerts if an image that contains webshells or mining programs is installed on your server. Viruses and malicious programs Security Center detects viruses, trojans, mining programs, malicious scripts, and webshells in containers. Intrusion into containers Security Center detects intrusions into containers from attackers who exploit application-layer vulnerabilities, unauthorized operations in containers, and application-to-application spread of malicious scripts in containers. Container escapes Security Center detects container escapes caused by improper container configurations, Docker vulnerabilities, or operating system vulnerabilities. High-risk operations Security Center detects sensitive host directories mounted to containers, Docker API leaks, Kubernetes API leaks, and containers started based on suspicious privilege escalation. This minimizes the risk of attackers exploiting these vulnerabilities.

Security Center supports various types of common sensitive files, including application configurations that contain sensitive information, general private keys of certificates, credentials for application authentication or logons, and credentials for cloud server providers. Note Only image system vulnerabilities can be fixed with a few clicks. Image application vulnerabilities, image baseline risks, malicious image samples, and sensitive image files can only be detected.	Value-added	Value-added	Value-added
Use the feature of proactive defense for containers	Security Center provides the feature of proactive defense for containers. The feature allows you to detect risks on an image when you use the image to create resources in a cluster. The feature also allows you to create a container defense policy for a cluster. If an image hits the container defense policy, Security Center handles the image that is started in the cluster based on the action of the policy. The action can be Block, Alert, or Allow. This ensures that the image does not affect your business.
Use container escape prevention	The feature of container escape prevention detects high-risk operations from multiple dimensions such as processes, files, and system calls, and establishes protection barriers between containers and hosts. This effectively blocks escape behavior and ensures the runtime security of containers.
