Single Sign On is the process of allowing a user to use one set of logon credentials, typically a
username and password to gain access to several different applications within a system.
To follow are a list of advantages of a SSO architecture:
It allows a perceived ease of use and reduces the number of complaints about passwords
It diminishes the chance of phishing
It enables users to remember and manage fewer password and username for each
application they need to access
To follow are a list of disadvantages of a SSO architecture:
If someone unauthorized gains access, they effectively could gain access to more than one
application
If availability is lost, then users are locked out of all system connected to the Single Sign On.
The Public Safety and first responders (PSFRs) industry (Police, Fire Fighters, FEMA, Shock Trauma)
would greatly benefit from the use of a single sign-on architecture. The on-demand access to public
safety data is critical to ensuring the PSFRs can protect life and property during an emergency. No
one would want a PSFR to be trying to remember multiple passwords if they were coming to help
you or a loved one in need.
