Table 1 HSS functions and features

Feature

Description

Asset management

Provide centralized asset overview, asset fingerprint management, server management, and container management. You can check your asset running status, asset fingerprints, and asset types; and manage assets by server or container.

Vulnerability management

Detect vulnerabilities and risks in Linux, Windows, Web content management systems (Web-CMS), and applications.

Baseline check

Scan for unsafe settings, weak passwords, and password complexity policies in server OS and key software.

A security practice baseline can be used for scans. You can customize baseline sub-items used in scan.

You can repair and verify the detected risks.

Container image security

Scan the images that are running or displayed in your image list, and provide suggestions on how to fix vulnerabilities and malicious files.

Application protection

Protect running applications. You simply need to add probes to applications, without having to modify application files.

Currently, only Linux servers are supported, and only Java applications can be connected.

Web page tampering prevention

Detect and prevent tampering of files in specified directories, including web pages, documents, and images, and quickly restore them using valid backup files.

Ransomware prevention

Detect known ransomware and support user-defined ransomware backup and restoration policies.

File integrity monitoring

Check the files in the Linux OS, applications, and other components to detect tampering.

Intrusion detection

Identify and prevent intrusion to servers, discover risks in real time, detect and kill malicious programs, and identify web shells and other threats.

Container intrusion detection

Scan running containers for malicious programs including miners and ransomware; detect non-compliant security policies, file tampering, and container escape; and provide suggestions.

Whitelist management

To reduce false alarms, import events to and export events from the whitelist. Whitelisted events will not trigger alarms.

Policy management

You can group policies and servers to batch apply policies to servers, easily adapting to your business scenarios.

Security report

Check weekly or monthly server security trend, key security events, and risks.

Security configuration

Configure common login locations, common login IP addresses, the SSH login IP address whitelist, and automatic isolation and killing of malicious programs.
