Protecting Folders on Linux

Linux offers advanced file encryption methods and file permission settings for folder protection.

Using Encryption (GnuPG)

Open a terminal. Use the following command to encrypt the folder: tar -cvf - /path/to/folder | gpg -c -o You will be prompted to set a password.

Using File Permissions

Stay Updated: Keep your operating system and any third-party software up to date to protect against vulnerabilities.
