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.

Automatic and manual vulnerability scans are supported. Automatic scan can be performed in the early morning every day at the preset time. You can also perform manual scan to view the vulnerabilities of target servers or of the current server.

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.

Constraints

The basic edition supports automatic scan and viewing of Linux and Windows vulnerabilities, but does not support server view switching or vulnerability handling.
The Server Status is Running, Agent Status is Online, and Protection Status is Protected. Otherwise, vulnerability scan cannot be performed.

Table 2 describes the OSs that support vulnerability scan and fix.

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 Types of vulnerabilities that can be scanned and fixed in each HSS edition.

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.

Procedure

Log in to the management console.
Click in the upper left corner of the page, select a region, and choose Security > Host Security Service.
