Tech Guides :: Information Security :: Secure Communication
Secure Communication Overview
Computers and the programs that run on them use user-names and passwords to determine who can access them. Many programs allow the transmission of this information to be sent (transmitted) in the clear. For the security of HSU users' confidential data, ITS can no longer support systems and programs that transmit user-names and passwords in clear text over the network. This transition will undoubtedly cause some pain and, initially, extra work for everyone involved, but the end result will be a safer, more trustworthy computing environment.
Email Client Overview
What this means to most users is that their email client (Outlook, Eudora, Entourage) will have to be re-configured to use secure communications. This process consists of installing a certificate file and re-configuring the email client to use SSL (Secure Socket Layer protocol).
