Note that there are other multi-factor solutions that work with ISE, but are transparent to ISE. Anyconnect NAM (unique chaining scheme) for on-campus.Cisco ASA/ Anyconnect with 2FA Identity sources such as RSA secure ID for remote access/off campus support.( Cisco Identity Services Engine Network Component Compatibility, Release 2.2 - Cisco) RSA Secure ID, Smartcard) or any RADIUS RFC-2865 compliant token server for on or off campus support. ISE supports two factor authentication mechanisms using the following methods ISE and Two Factor Authentication Scenarios The goal of the two factor authentication is not to allow an attacker impersonate the owner when the attacker holds the possession of a device (laptop/workstation) etc. The two factors can be any of the factors mentioned above but typically it uses user credentials/ Passcode and Token/ Smartcard as two factors. In general, two factor authentication is a form of strong authentication used in government, industry etc. Three-factor authentication uses all three forms. Single-factor authentication uses only one of the three forms of authentication, while two-factor authentication uses any two of the three forms. ( Cornell University )Īuthentication can involve something the user knows (e.g., a password), something the user has (e.g., a smart card), or something the user “is” (e.g., a fingerprint or voice pattern). Without 2-factor authentication, stealing the device would allow an attacker to impersonate the owner of the device with 2-factor authentication, the attacker would still have another authentication burden to overcome. ![]() CISCO IOS XE TWO FACTOR AUTHENTICATION PASSWORDSo, we might require that a principal not only possess a device but also know some secret password (often known as a PIN, or personal identification number). Here are two well-known definitions for two factor and in general multi-factor authentication.Ģ-factor authentication becomes important - an authentication process that involves 2 independent means of authenticating the principal.
