As Internet security issues become increasingly prominent, the security of major websites and applications has become an increasingly important issue. Especially in website operation and maintenance management, tools such as WebShell are often needed for maintenance and repair. However, WebShell is also often used by hackers and becomes an entry point for attackers to invade. This article will introduce the WebShell security settings of the Pagoda Panel to help website administrators improve the security of the site.

1. The concept and common uses of WebShell

1. Concept

WebShell is a program that runs on the Web server and is usually used to remotely manage the files of the Web server. and database, etc. Its essence is a command line tool that allows server administrators to operate through the web interface.

2. Common uses

WebShell is mainly used for remote management of Web servers, including:

• Manage files and directories of Web servers, such as uploading files and downloading files, modify files, delete files, create directories, etc.;
• Manage the database of the Web server, such as backing up the database, restoring the database, adding tables, deleting tables, querying tables, etc.;
• Execute server commands , such as restarting the server, checking server status, killing processes, etc.

2. WebShell security risks and countermeasures

1. Security risks

WebShell can help administrators quickly maintain the server, but it is also vulnerable to hacker attacks and malicious code An important entrance to take advantage of. Attackers can execute malicious code through WebShell, such as uploading Trojans, executing commands, modifying Web server configuration files, etc., in order to obtain sensitive server information, control the server, steal user data, etc.

2. Countermeasures

In order to prevent WebShell from being used by attackers, the following security measures need to be taken:

(1) Regularly scan the web server to look for abnormal WebShell. You can use professional scanning tools or write your own scripts to scan.

(2) Set the WebShell access password. Generally speaking, WebShell can only be accessed by administrators. In order to prevent it from being accessed by others, an access password needs to be set. At the same time, do not set this password too simple. It is best to include numbers, letters, and special characters.

(3) Bind IP address and port. WebShell can be bound to a specific IP address and port through the Web server's configuration file to prevent illegal access.

(4) Restrict WebShell’s file operation permissions. In order to prevent attackers from uploading malicious files, WebShell can be restricted to only operate specific files and directories, or can only upload specific types of files.

3. WebShell security settings of Pagoda Panel

Pagoda Panel is a tool that provides a Web management interface for servers and is widely used for Linux server management. In the Pagoda panel, WebShell is also an important feature. Administrators can quickly maintain servers and applications through WebShell.

In order to improve the security of WebShell, the Pagoda panel provides the following security settings:

1. Set WebShell password

The administrator can set the WebShell password in the Pagoda panel. Click the "Security" option on the homepage of the panel to enter the security setting interface. Find the WebShell switch in the "Web Public Directory" column. After turning on the switch, you can set the WebShell access password.

2. Restrict WebShell file operation permissions

After turning on the switch, you can set the WebShell access IP address and port.

In short, WebShell is a very important tool in server management, but it also faces security risks. In order to ensure the security of the server, administrators need to take a series of security measures, such as setting access passwords, restricting file operation permissions, binding IP addresses and ports, etc. The Pagoda panel provides these security settings, making it easier for administrators to maintain servers and applications.
