Discussion:
Changing temporary passwords to permanent passwords immediately after system logon ensures that the necessary strength of the authentication mechanism is implemented at the earliest opportunity, reducing the susceptibility to authenticator compromises.
Upon assessment, assessors must determine if-
Determine if an immediate change to a permanent password is required when a
temporary password is used for system logon.
Assessors are instructed to-
Examine: [SELECT FROM: Identification and authentication policy; password policy; procedures addressing authenticator management; system security plan; system configuration settings and associated documentation; system design documentation; password configurations and associated documentation; other relevant documents or records].
Interview: [SELECT FROM: Personnel with authenticator management responsibilities; personnel with information security responsibilities; system or network administrators; system developers].
