ITPEC IP April 2021 Question 37
ITPEC IP April 2021 — Question 37 of 100
Single sign-on lets a user authenticate once and then access multiple authorized services without signing in again to each one. A central identity mechanism or trusted authentication token communicates the established identity to participating applications, improving convenience and reducing repeated password entry.
Answer (d)
Why not others:
- server-side storage describes a thin-client or cloud-data characteristic
- distributing data across disks describes RAID
- combining passwords with fingerprint and iris factors describes multifactor authentication
Key rule: SSO centralizes or federates authentication so one login session serves multiple systems.
