Do you manage multiple computing systems, or critical systems? If your password is compromised, what are the implications? If the answers to these questions are “yes” and “very bad” then this session may be for you. We will discuss protecting systems with one time passwords as a factor in multi-factor authentication. The systems described can be used to protect other resources such as Apache web servers or windows systems, but the primary focus and our experience is for Linux.
