Enabling Server Protection
Scenarios
This section describes how to enable the basic, enterprise, or premium edition for a server.
Prerequisites
- Ensure that the agent has been installed on the server and is online. For details, see Installing the Agent on Cloud Platform Servers.
Constraints
- After the Windows firewall is enabled, HSS automatically adds firewall rules hostguard_AllowAnyIn and hostguard_AllowAnyOut to allow all inbound and outbound traffic. This ensures that the firewall does not affect your services. If HSS detects a brute-force attack, it adds an inbound rule to the firewall to block the attack source IP address. This does not affect your servers.
- Do not disable the Windows firewall when using HSS, or HSS cannot block the source IP addresses of brute-force attacks. Once it is disabled, HSS may fail to block the attack source IP addresses even after you manually enable it again.
Enabling the Enterprise/Premium Edition
- Log in to the management console.
- Click
in the upper left corner and select a region or project.
- In the upper left corner of the page, click
and choose .
- In the navigation pane on the left, choose .
- Click OK. If the Protection Status of the target server is Enabled, the enterprise or premium edition has been enabled.
- A quota can be bound to a server to protect it, on condition that the agent on the server is online.
- After HSS is enabled, it will scan your servers for security issues. Check items vary according to the edition you enabled.
- (Optional) Configure alarm notification, protection policies, server login protection, and malicious program isolation and removal.
- Configuring alarm notifications
After HSS is enabled, alarms are displayed on the console by default. To learn the security risks of servers, containers, or web pages in a timely manner, you can enable alarm notification, and HSS will notify you of risks by SMS or email. For details, see Alarm Configuration.
- Configuring protection policies
Each HSS edition provides a group of protection policies preset with default settings. You can enable or disable policies and adjust protection rules as needed. For details, see Policy Management.
- Configuring login protection
To enhance server login security, perform the operations in Enabling 2FA, Configuring Common Login Locations, Configuring Common Login IP Addresses, and Configuring an SSH Login IP Address Whitelist.
- Enabling malicious program isolation and removal
If this function is enabled, HSS will automatically isolate identified malicious programs, such as backdoors, Trojans, and worms, to help you handle security risks. For details, see Isolating and Killing Malicious Programs.
- Configuring alarm notifications
Viewing Scan Details
After server protection is enabled, HSS will immediately perform a comprehensive scan on the server. It may take a long time. After the scan is complete, you can check its details.
- Choose Servers tab page. . Locate the server on the
- Check the Risk Level column of the server.
Table 1 Risk status Status
Description
Pending risk detection
The server is neither protected nor scanned.
Safe
No risks were found in the comprehensive scan on the server; or the protection has just been enabled, and no risks have been found yet.
Risky
The server has security risks.
- Hover the cursor over the risk status to view the risk distribution.
You can click a value to go to the details page.
Advanced Protection
HSS provides a series of advanced defense functions. You can enable or use them as required to enhance the security protection level of your servers. For details, see Table 2.

---|---|---|
To protect your applications with RASP, you simply need to add probes to them, without having to modify application files. |
Premium edition |
|
The function can detect and defend against ransomware. It can automatically back up data either at a scheduled time, or immediately if ransomware is detected. This can help you defend against ransomware and reduce loss. Ransomware prevention is automatically enabled with the container edition. HSS will deploy honeypot files on servers and automatically isolate suspicious encryption processes. You can modify the ransomware protection policy. |
Premium edition |
|
Application process control helps to enhance the security of applications and processes running on servers. It can automatically identify and analyze application processes, and classify them into trusted, suspicious, and malicious processes. It allows trusted processes to run, and generates alarms for suspicious and malicious processes. This helps to build a secure environment for application processes, and protects servers from untrusted or malicious application processes. |
Premium edition |
|
This function combines cloud-based and local antivirus mechanisms to scan executable files, compressed files, scripts, documents, images, and audiovisual files for viruses. You can perform quick scan, full-disk scan, and custom scans on servers as needed to detect and remove virus files in a timely manner, enhancing the virus defense of the system. |
Professional, enterprise, and premium editions |
|
The dynamic port honeypot function is a proactive defense measure. It uses a real port as a honeypot port to induce attackers to access the network. In the horizontal penetration scenario, the function can effectively detect attackers' scanning, identify faulty servers, and protect real resources of the user. |
