Application of Encrypted File System (EFS) in Linux)

 
Open-source systems have been widely used and promoted in enterprises, especially in server construction and data storage, and their security issues have attracted everyone's attention. Based on these considerations, open-source systems provide many excellent and practical security tools and mechanisms for data security, such as access control lists and digital certificates, this article introduces the Encrypted File System (EFS) to protect the data security of enterprise users on open-source systems.
 
Select to use EFS during Linux Installation
 
First, we will introduce a very simple method to use the EFS file system. Taking the installation steps of Fedora as an example, you can select relevant options for installation.
You can create a new partition in the free space, select a partition for editing, and delete some partitions. In Figure 1, select the [Encrypted File System] Option and enter the password required to access EFS according to system requirements, as shown in figure 2. Next, follow the Linux installation steps and follow the system prompts to install the system. After the system is successfully installed, you have a secure encrypted file system, and every time you log on to the system, the system requires the user to enter the password set in step 2 for secure access.
