Vulnerability Management Overview

Vulnerability management can detect Linux, Windows, Web-CMS, and application vulnerabilities and provide suggestions, helping you learn about server vulnerabilities in real time. Linux and Windows vulnerabilities can be fixed in one-click mode. This section describes how the vulnerabilities are detected and the vulnerabilities that can be scanned and fixed in each HSS edition.

The vulnerability list displays vulnerabilities detected in the last seven days. After a vulnerability is detected for a server, if you change the server name and do not perform a vulnerability scan again, the vulnerability list still displays the original server name.

How Vulnerability Scan Works

Table 1 describes how different types of vulnerabilities are detected.

**Table 1** How vulnerability scan works
Type	Mechanism
Linux vulnerability	Based on the vulnerability database, checks and handles vulnerabilities in the software (such as kernel, OpenSSL, vim, glibc) you obtained from official Linux sources and have not compiled, reports the results to the management console, and generates alarms.
Windows vulnerability	Synchronizes Microsoft official patches, checks whether the patches on the server have been updated, pushes Microsoft official patches, reports the results to the management console, and generates vulnerability alarms.
Web-CMS vulnerability	Checks web directories and files for Web-CMS vulnerabilities, reports the results to the management console, and generates vulnerability alarms.
Application vulnerability	Detects the vulnerabilities in the software and dependency packages running on the server, reports risky vulnerabilities to the console, and displays vulnerability alarms.

Types of Vulnerabilities That Can Be Scanned and Fixed

For details about the types of vulnerabilities that can be scanned and fixed in different HSS editions, see Table 2.

The meanings of the symbols in the table are as follows:

√: supported
×: not supported

HSS can scan for Web-CMS and application vulnerabilities but cannot fix them. You can log in to your server to manually fix the vulnerability by referring to the suggestions displayed on the vulnerability details page.
You can configure the automatic scan period, automatic scan scope, and vulnerability whitelist. For details about how to configure the automatic scan period and automatic scan scope, see Automatic Vulnerability Scan. For details about how to configure the vulnerability whitelist, see Managing the Vulnerability Whitelist.
