Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

"I often need to remotely access a machine at home to do some form of work, and while I find that most times a simple SSH connection is sufficient, now and then I find it helpful to be able to use or test an application with a GUI. To allow remote access, while maintaining a reasonable level of security I implement a defense in depth strategy using a combination of components and configurations on a computer in a protected zone on my home network in an effort to to reduce the attack surface while satisfying my need for remote access.

"Step One: Configure user accounts with obscure non-dictionary user names. For your user account, I would recommend using letters and numbers but not symbols as certain symbols are reserved for the system. Choose something that you can remember but wouldn't exist in a dictionary. I also recommend using a phrase rather than a password of no less than 16 characters in a combination of mixed case letters, numbers, and symbols. Not only is a phrase easier to remember than a password, it is an order of magnitude more difficult to crack."
