Deep Dive into Changes to the Identification and Authentication Family in FedRAMP Revision 5

The FedRAMP Program Management Office (PMO) has released new proposed baselines based on NIST Special Publication 800-53, Security and Privacy Controls for Information Systems and Organizations, Revision 5, (NIST SP 800-53 Rev5). Here we will take a closer look at the changes to the Identification and Authentication control family that the new baselines bring.

 

Considerable Changes to the Low, Moderate, and High baselines include:

  • Policies and procedures will now need to be designated as either organizational level, mission or business process level, or system level
  • A requirement to designate a specific official to manage the development, documentation, dissemination of policies and procedures
  • A requirement to update policies and procedures after specified events A change to generalize the types of access for privileged accounts requirement multifactor authentication
  • An addition of a new parameter selecting privileged and/or non-privileged accounts that are required to have replay-resistant authentication mechanisms for network access
  • Removal of a control step requires the disableing of an identifier after a specified period of inactivity
  • An addition of a new requirement to maintain a list of commonly used, expected, or compromised passwords and update the list at a specified frequency and when organizational passwords are suspected to have been compromised directly or indirectly
  • An addition of a new requirement to verify, when users create or update passwords, that the passwords are not found on the list of commonly-usedcommonly used, expected, or compromised passwords
  • An addition of a new requirement to transmit passwords only over cryptographically-protected channels
  • An addition of a new requirement to store passwords using an approved salted key derivation function
  • An addition of a new requirement to immediately select a new password upon account recovery
  • An addition of a new requirement to allow user selection of long passwords and passphrases, including spaces and all printable characters An addition of a new requirement to employ automated tools to assist users in selecting strong passwords
  • A change of acceptance criteria for external authenticators (third party credentials) to be NIST compliant as opposed to FICAM approved

 

Considerable Changes to the Moderate and High baselines include:

  • An addition of new parameters implementing multifactor authentication for local network, remote access, privileged accounts, and non-privileged accounts; so that one of the factors is provided by a device separate from the system gaining access
  • Removal of a parameter requiring changing default content of authenticators prior to information system installation
  • An addition of a parameter requiring defining specific events that require changing or refreshing authenticators
  • An addition of a new control requiring that users are identify proofed for logical access based on identify assurance level requirements
  • An addition of a new control requiring evidence of individual identification to be presented to the registration authority in order to reduce the likelihood of individuals using fraudulent identification to establish an identity
  • An addition of a new control requiring a registration code or notice of proofing be delivered through an out-of-band channel to verify the user’s address (physical or digital) of record
