Editions and Features

HSS comes in the basic, enterprise, premium, Web Tamper Protection (WTP), and Container Guard Security (CGS) editions, providing asset management, vulnerability management, baseline check, intrusion detection, ransomware protection, web tamper protection, and container image security functions. For details about the features of the editions, see Edition Details.

HSS comes in the basic, enterprise, premium, Web Tamper Protection (WTP), and container security editions. You can purchase or upgrade your edition as needed.
You can upgrade your editions in the following scenarios.
- If you have purchased the basic edition, you can upgrade it to the enterprise, premium, or WTP edition.
- If you have purchased the enterprise edition, you can upgrade it to the premium or WTP edition.

The premium edition is provided for free if you have purchased the WTP edition.

Features

HSS provides asset management, baseline check, ransomware prevention, and intrusion detection features, enhancing server security in all aspects. For details about the features of different editions, see Edition Details.

**Tabla 1** HSS features
Feature	Description
Asset management	Perform a deep scan of the accounts, ports, processes, web directories, software, and auto-started tasks on your servers. You can manage all of your digital assets on the Asset Management page.
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 and a compliance standard baseline can be used for scans.
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. So far, only Java applications can be protected.
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	Monitor new files and running processes in real time, control risks in new files, dynamically generate bait files for proactive defense, accurately identify ransomware, and periodically back up servers based on user-defined 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 configuration	You can configure common login locations, common login IP addresses, the SSH login IP address whitelist, and automatic isolation and killing of malicious programs.

Recommended Editions

To protect test servers or individual users' servers, use the basic edition. It can protect any number of servers, but only part of the security scan capabilities are available. This edition does not provide protection capabilities, nor does it provide support for DJCP Multi-level Protection Scheme (MLPS) certification. The pay-per-use basic edition is free of charge for 30 days.
If you need to obtain the DJCP MLPS L2 certification, purchase the enterprise edition. If you need to obtain the DJCP MLPS L3 certification, purchase the premium edition. If you need to obtain the DJCP MLPS certification for a website, purchase the Web Tamper Protection edition.
If your servers store important data assets, have high security risks, use publicly available EIPs, or there are databases running on your servers, you are advised to purchase the premium or Web Tamper Protection edition.
For servers that need to protect websites and applications from tampering, the WTP edition is recommended.
For containers that need to enhance image security, container runtime security, and to comply with security regulations, CGS is recommended.
- You are advised to deploy HSS on all your servers so that if a virus infects one of them, it will not be able to spread to others and damage your entire network.
- In the Pay-per-use mode, the HSS enterprise edition stops charging if the servers it protects are stopped.
