I’m gonna take Linux Mint for an example for this article because friend of mine asked me to go his warehouse next week (Today is Sunday and it’s afternoon while I’m writing this article). to install Linux Mint on his laptop.
After installation. (if user’s $HOME directory is not encrypted by option).
- System software updates
Debian –based packet management system is made simple for system updates. First of all it’s good to update repository –sources up to date by “sudo apt-get update” –terminal command.
After it sudo apt-get upgrade –Y (-Y Parameter is switch for “Yes to all”.).
- Setting up the Firewall
sudo apt-get install gufc;
ufc enable – enables firewall every time when the user boot up his computer.
- Encrypting the home-directory content after installation
It’s possible to encrypt single – user’s home directory content down at the setup-stage.
- Backup all the files located on the becoming encrypted $HOME -directory
- Create temporary user –account.
- Log out and log in the account created down at the previous step.
- sudo apt install ecryptfs-utils cryptsetup
- sudo ecryptfs-migrate-home -u useraccount by replacing the ”useraccount” the user¨s account login name.
- Log out and log in your user account and now the becoming files are encrypted!
- Virus Defender
There’s no need to use Vrius Defender program in the Linux System.
- Introdouce yourself to the “rootkit”. scanning tools. Rootkit –piece of softwares are the programs that red-hat crackers may use in when they are trying to hijack root-user password.
