Single sign-on (SSO) systems allow users to access multiple systems after authenticating once but this can disadvantage security if the SSO is breached. If an intruder breaches the SSO, they would have access to all systems connected to that SSO implementation, unlike individual breaches that are limited to one system. The document discusses security disadvantages of SSO and identifies that allowing an intruder access to all linked systems if the SSO is compromised is considered the biggest disadvantage.

1. When discussing the security of SSO systems, which of the following is considered a
disadvantage?
A. Single sign-on requires much more maintenance and overhead because all systems are tied
together.
B. The biggest disadvantage to single sign-on is that system time on all systems must be held to
very tight standards; if deviated from, this can cause serious access problems.
C. There are no real disadvantages to single sign-on.
D. If single sign-on is breached, it offers the intruder access to all systems tied to the SSO
implementation.
Solution
D. If single sign-on is breached, it offers the intruder access to all systems tied to the SSO
implementation.
Single sign-on (SSO) offers the attacker potential access to many systems tied to SSO when
authenticated only once.
