1.  Introduction

   The Secure Shell (SSH) transport layer protocol [!RFC4253] is widely
   used as a mechanism for securing access to remote hosts.  In addition
   to providing a terminal connection to a remote host, SSH also
   supports file transfer and remote access (VPN) functionality.  It is
   also used to provide remote procedure call (RPC) capabilities in
   applications such as Git.

   While SSH permits a high level of security to be achieved, achieving
   a high security configuration requires a considerable degree of
   attention to detail.  Numerous ?how to? guides found on the Internet
   advise the user to engage in many unsafe practices.  These include:
