Linux deletes directories and files using the rm Linux command. You need to know what will happen when you press "Enter" to use this tool in a safe manner. Here's what you need to understand to use the rm Linux command securely and effectively.
Linux file permissions enable you to allow or prevent other users from viewing your files, making them crucial to robust security and privacy. But how can you change file and folder permissions on Linux from the Command Line to improve the security of your filesystem?
Today we'll cover how to encrypt and securely transfer files using GPG. GPG is a free, open-source encryption program that uses public-key cryptography, which means you can send encrypted files without ever having to send your private key over email or any other insecure channel. The only way to decrypt the file is if you have both your public and private keys, which means even if someone were able to intercept and read the message before it reached its intended recipient, it would be useless without the private key.
Linux has different security permissions, each impacting what can be done with a file and a directory.
