Token secrets are either based on asymmetric keys or symmetric (single) keys. The token contains a secret that is used to prove the claimant is in control of the token. Tokens are used by claimants to prove their identity and authenticate to a system or application, and can be either software or hardware based. The most common examples of this authentication type are hardware and software tokens, such as the RSA SecurID fob or a smart card, that generate a random number sequence, or contain an embedded code, to be used by the user during the authentication process. 1075, Section 4.7, Authenticator Management (IA-5), which includes a minimum of fourteen characters, and a mixture of at least one numeric, one special character, one uppercase and one lowercase letter. To be considered an appropriate authentication method, passwords must meet the requirements identified in Pub. Disallow sequential digit strings (e.g., 12345678 or 98765432) andĮxamples of this type of authentication are passwords or passphrases, usually employed with a username, PINs created and known by the user, for use with challenge questions, or patterns, such as a sequence on a keypad.Multi-factor authentication is also required when accessing firewalls over an in-band connection, to provide an appropriate level of assurance of the identity of the individual configuring the device.Īs a new requirement, if selecting an implementation that uses a personal identification number (PIN) (e.g., for activation of a token), the PIN must meet the following requirements: For example, authenticating using two passwords does not constitute multi-factor they are both examples of “something you know” and can both only satisfy this category. One type of authentication may not be repeated in attempting to satisfy multi-factor authentication. Biometric data may be verified in the form of a fingerprint, voiceprint or iris scan, using provided hardware and then entering a PIN or password in order to open the credential vault. Federal Information Processing Standards (FIPS) 201, Personal Identity Verification (PIV) of Federal Employees and Contractors, guidelines the standard for secure and reliable forms of identification. More information is provided below for implementation guidance. The basic principle is that the key embodies a secret which is shared between the lock and the key, and the same principle underlies possession-factor authentication in computer systems. Possession factors have been used for authentication for centuries, in the form of a key to a lock. Something you have: hardware or software token.Something you know: password, Personal Identification Number (PIN), challenge question, or pattern.This access requires the use at least two of the following types of authentication: 1075, Section 4.7, Identification and Authentication (Organizational Users) (IA-2)). Multi-factor authentication is required for “all remote network access to privileged and non-privileged accounts for information systems that receive, process, store or transmit FTI” (Pub. An agency may choose to implement a system appropriate to its needs, but all requirements contained in this memorandum that pertain to that implementation must be fulfilled. This message discusses detailed requirements that must be applied when procuring or developing various multi-factor authentication implementations. This document explains the different authentication factors and addresses the security requirements for implementing multi-factor authentication to meet the requirements of the Office of Safeguards. The number of factors is important, as it implies a higher probability that presenter of the identify evidence is who they claim to be. Multi-factor authentication decreases the probability that the requestor is not the person who he says he or she is. Multi-factor authentication drastically reduces the risk of identity theft and unauthorized disclosure of FTI. looking to reduce costs, allow employees to work from home or telework. These requirements are more important as agencies. 1075, is any access to an agency information system by a user communicating through an external network (i.e. It also requires that any remote access has multi-factor authentication implemented. 1075) requires that all access to federal tax information (FTI) occurs from agency-owned equipment.
