8 Frequently Asked Questions 8.1.4 What Should I Do If a Pay-Per-Use Scan Job Fails? Click Scan Again. 8.1.5 Is There Anything I Need to Know Before Purchasing Professional Edition? If you have used Basic Edition before purchasing Professional Edition, set Domain Names to a number greater than or equal to the existing number of websites in the asset list. If you do not want to upgrade an existing domain name to Professional Edition, delete it before purchasing Professional Edition. If you only want to upgrade all domain names of Basic Edition to Professional Edition, set Domain Names to a number equal to the existing number of websites in the asset list. If you want to scan more websites, set Domain Names to your desired number, which must be greater than the existing number of websites in the asset list. Once purchase succeeded, all existing domain names of Basic Edition are upgraded to Professional Edition by default. 8.2 About Functions 8.2.1 What Are the Differences Between VSS and Conventional Vulnerability Scanners? Item Conventional Scanner VSS Usage Install clients in advance. Users do not need to install clients. Instead, users can start a scan simply by creating a job on the console (enter a domain name or IP address), saving O&M costs. Vulnerability database update The vulnerability database is updated manually, which means that the latest information cannot be synchronized in a timely manner. The vulnerability database is updated on the cloud, with the latest vulnerabilities covered. VSS can check for the latest vulnerability in users' websites. 8.2.2 Which Vulnerabilities Can Be Scanned by VSS? Currently, the following vulnerabilities can be scanned: Weak passwords SSH, RDP, SMB, MySQL, Microsoft SQL Server, MongoDB, Redis, Oracle, DB2, GaussDB, Postgres, and Telnet Front-end vulnerabilities Issue 20 (2018-08-30) Copyright Huawei Technologies Co., Ltd. 51

The change of a job's status may be: Waiting > In progress > Complete Waiting > Canceled Waiting > In progress > Canceled 8.2.7 Why Does the Automatic Login During a Scan Job Fails? VSS automatically finds the username and password text boxes and the login button on the login page submitted by the user for login. After the login is successful, VSS also finds the logout link to prevent it from logging out from the website. The success rate of finding these elements depends on the page complexity. If your web page can be accessed only after login, configure login parameters so that VSS can discover more vulnerabilities for you. You can select either of the following login methods (see Figure 8-11). To improve the login success rate, you are advised to set both of them. Issue 20 (2018-08-30) Copyright Huawei Technologies Co., Ltd. 56

8 Frequently Asked Questions 8.3 About Website Scan 8.3.1 How Long Does a Scan Take? Duration of a website scan depends on the website size. Typically, scanning a 200-page website takes approximately 30 minutes. A certain number of detection requests are sent to the website being scanned, slightly increasing the load of the website. NOTE The duration of re-scanning the same job is shorter than the initial scan. 8.3.2 Why Is a Job Automatically Canceled in the Job Scan Process? If a job is automatically canceled in the job scan process, there are two possible reasons: The website login settings are not configured. You did not configure website login settings and VSS cannot perform in-depth access, leading to automatic job scan cancelation. You are advised to configure website login settings and perform the scan job again. Network exceptions occur during the job scan. If network exceptions occur, VSS cannot access the website and the job will be automatically canceled. You are advised to perform the scan job again when the network becomes normal. 8.3.3 How Do I Set a Scheduled Scan? When creating a job, select the Timing check box and set the scan time. Then, click the Timing button. The system will start the job at the set time. See Figure 8-16. NOTE The start time must be within the coming one week. Figure 8-16 Setting a scheduled scan job Issue 20 (2018-08-30) Copyright Huawei Technologies Co., Ltd. 62

8 Frequently Asked Questions 8.3.4 Can the Authenticated Document in the Root Directory of the Website Be Deleted After Domain Name Authentication Is Complete? No. VSS will read this document during subsequent scanning and check whether the ownership of the website is still valid. If the authenticated document is deleted, a failure message is displayed when the domain name is scanned again. 8.3.5 Why Is the Authenticated Document Not Displayed After I Click Download Authenticated Document? The downloaded authenticated document may be intercepted by the browser. Check the blocking settings of the browser to see whether it is so. 8.3.6 Why Am I Frequently Prompted that the Domain Name Format Is Incorrect During Job Creation? When creating a job, you need to enter the domain name format so that VSS can identify the protocol (HTTP or HTTPS) used by the website. The correct domain name format is either of the following: http:// + domain name or IP address https:// + domain name or IP address For example, if the HTTPS protocol is used and the IP address is 10.10.10.1, the target website needs to be set to https://10.10.10.1 during job creation. 8.3.7 What Is the Authenticated Document Used For? The authenticated document is used to verify the ownership of a user and a scanned website. To verify the ownership of the user and the scanned website, VSS generates a unique document. If the document is saved in the root directory of the website and the document can be accessed by external users, VSS considers that the current user is the owner of the website. 8.3.8 Why Does Domain Name Authentication Fail? Possible causes for domain name authentication failures are: The authenticated document is not saved in the root directory of the website. Save the authenticated document to the root directory of the website and perform authentication again. The domain name cannot be accessed. Ensure that the domain name can be accessed and perform authentication again. The domain name information does not comply with rules and regulations. Websites containing content that does not comply with laws and regulations do not support VSS. Issue 20 (2018-08-30) Copyright Huawei Technologies Co., Ltd. 63

8 Frequently Asked Questions 8.3.9 How Do I Upload an Authenticated Document to the Root Directory of a Website? Tomcat, Apache, and IIS Servers Step 1 Find the root directory of the server used by the website, that is, the directory at the same level as the index file. The root directories of common servers are as follows: Server Used by a Website Tomcat Apache IIS Root Directory Tomcat deployment address/webapps/root/ The default value is /var/www/html. Set the directory based on the site requirements. The default value is C:\inetpub\wwwroot. Set the directory based on the site requirements. Nginx Servers Step 2 Save the authenticated document to the directory found in Step 1. NOTE ----End Steps for other servers are similar. Specifically, you only need to save the authenticated document to the directory at the same level as the index file. For Nginx servers, perform the following steps: Step 1 Step 2 Step 3 Log in to the Nginx server as user root. Upload the authenticated document to any directory (the nginx process has the read permission on this directory). The following uses the /opt/mock directory as an example. Configure the location information of the Nginx http module, as shown in Figure 8-17. The location information shows that the authenticated document can be obtained in /opt/mock.

8 Frequently Asked Questions NOTE ----End If the server is not fully occupied, the newly created job can be performed immediately and the job status is In progress. If the server is fully occupied, the job waits in the queue and its status is Waiting. If a scan job takes more than two hours and its progress is greater than 20%, the system displays a message indicating that the extra part beyond the free quota has been billed on a pay-per-use basis. You decide to cancel this job or not as required. 8.3.14 What Should I Do When a Website Scan Fails with a Message Displayed Indicating Connection Timeout? The possible causes and solutions are as follows: 1. Your website is unstable. Open the website and check whether the connection is normal. Try scanning again. 2. Your website cannot be accessed from the Internet. As a result, VSS cannot access and scan your website. 3. A firewall or another security policy has been configured on your website. As a result, the IP addresses of VSS (49.4.69.1, 114.115.215.94, 114.115.211.231, 117.78.41.118, 117.78.41.126, 43.254.3.176, and 117.78.46.77) are mistakenly intercepted as attackers. Add the IP addresses of VSS to the whitelist. NOTE If your website cannot be accessed, check whether it is working properly. If you have any questions, feel free to send your problem on the VSS console. 8.4 About Host Scan 8.4.1 How Do I Perform Host Authorization? Procedure Step 1 Step 2 Log in to the management console.
