A MAJOR risk of using single sign-on (SSO) is that it:
A. has a single authentication point.
B. represents a single point of failure.
C. causes an administrative bottleneck.
D. leads to a lockout of valid users.
Answer / guest
Answer: A
The primary risk associated with single sign-on is the
single authentication point. If a password is compromised,
access to many applications can be obtained without further
verification. A single point of failure provides a similar
redundancy to the single authentication point. However,
failure can occur at multiple points, such as, data, process
or network. An administrative bottleneck may result when the
administration is centralized in a single step entry system.
This is therefore an advantage. User lockout can occur with
any password authentication system and normally is remedied
swiftly by the security administrator resetting the account.
