Hi Guys,
Protect Grub using a password is always a good security practice. It is also very easy to do.
Please follow the steps given below.
1) Login to system via SSH
2) Generate a MD5 password using " grub-md5-crypt" tool
# grub-md5-crypt
Password:
Retype password:
$1$19oD/1$NklcucRUpoNYul8OfEURc2
3) Now you got the md5 password. Save it a safe place and open "/boot/grub/grub.conf" and add the below line.
vi /boot/grub/grub.conf
password --md5 $1$19oD/1$NklcucRUpoNYul8OfEURc2
Reboot the system and if you try to edit the grub, it will ask you for the password.
Give it a try!
