What are the main advantages and disadvantages of Single Sign On solutions?

Answer 1

Advantages of Single-sign on

• Users select stronger passwords, since the need for multiple passwords and change synchronization is avoided.

• Inactivity timeout and attempt thresholds are applied uniformly closer to user points of entry.

• It improves the effectiveness/timeliness of disabling all network/computer accounts for terminated users.

• It improves an administrator's ability to manage users and user configurations to all associated systems.

• It reduces administrative overhead in resetting forgotten passwords over multiple platforms and applications.

• It provides users with the convenience of having to remember only a single set of credentials. This also improves security as users find it easier to remember their credentials and do not have to write them down, allowing for a more efficient user logon process.

• It reduces the time taken by users to log into multiple applications and platforms.

Disadvantages of Single-Sign on

• Using only one SSO server can introduce a single point of network failure.

• Few software solutions accommodate all major operating system environments; a mix of solutions must be tailored to the enterprise's IT architecture and strategic direction.

• Substantial interface development and maintenance may be necessary, especially in the absence of industry-based standards.

• The SSO server and other host security must be hardened since Weaknesses can now be exploited across the enterprise.

• Most SSO-software packages include additional access control features for which purchaser is charged even if they are redundant of any existing controls.
