Intrusion prevention

The feature provides the built-in threat detection engine and allows you to configure prevention rules. This helps you detect and block intrusions in a more accurate manner.

The feature displays the data of intrusion prevention, vulnerability prevention, and breach awareness in real time. You can view the details of attack prevention and solutions to intrusions that are detected by the threat detection engine in real time.

Implementation of the threat detection engine

  • Threat intelligence

    The feature synchronizes the threat intelligence libraries of all malicious IP addresses and domain names that are detected across Alibaba Cloud, including the IP addresses and domain names of malicious visitors, scanners, and command-and-control servers. The feature defends against potential threats and blocks attack behavior to prevent large-scale attacks.

  • Basic protection

    The feature precisely intercepts common attacks, such as malicious port scanning, brute-force cracking, remote code execution, and vulnerability exploitation based on the intrusion prevention rules that are accumulated in attack and defense practices of Alibaba Cloud. This helps you protect assets against mining or ransomware.

  • Intelligent defense

    The feature identifies unknown attacks based on AI technologies and a large amount of data about attacks and attack characteristics. The feature also improves detection of more sophisticated attacks.

  • Virtual patching

    The feature supports installation-free virtual patches for business systems. The feature provides precision defense against common vulnerabilities, zero-day vulnerabilities, and N-day vulnerabilities.

  • Protection whitelist

    The feature allows you to configure whitelists to allow normal traffic that may have attack characteristics. This ensures that your business can run as expected.
