Overview

If policies such as asset collection, baseline check, and intrusion detection do not meet your server protection requirements, you can manage these policies.

Table 1 lists the policies that can be managed by each HSS edition. For details about how to configure policies, see Configuring Policies.

If you have different protection requirements, you can create a custom policy group to deploy different protection policies for different servers. For details, see Creating a Policy Group.

Intrusions

AV detection

Check server assets and report, isolate, and kill the detected viruses.

The generated alarms are displayed under Detection > Alarms > Server Alarms > Event Types > Malware.

After AV detection is enabled, the resource usage is as follows:

The CPU usage does not exceed 40% of a single vCPU. The actual CPU usage depends on the server status.

Login Security Check

Detect brute-force attacks on SSH, FTP, and MySQL accounts.

If the number of brute-force attacks (consecutive incorrect password attempts) from an IP address reaches 5 within 30 seconds, the IP address will be blocked.

By default, suspicious SSH attackers are blocked for 12 hours. Other types of suspicious attackers are blocked for 24 hours. You can check whether the IP address is trustworthy based on its attack type and how many times it has been blocked. You can manually unblock the IP addresses you trust.

Malicious File Detection

  • Reverse shell: Monitor user process behaviors in real time to detect reverse shells caused by invalid connections.

  • Detect actions on abnormal shells, including moving, copying, and deleting shell files, and modifying the access permissions and hard links of the files.
