Identification and Authentication The following are the Mandatory Procedures that support the Identification and Authentication section of the Default Security Requirements: 4.1.1. Manage Identification and Authentication Agencies should ensure that only individuals that have the pre-established right to access systems can do so: 4.1.1.1 Verify User Identity To ensure that system accounts are only extended to known and trusted individuals, these individuals must be fully identified via external identity verification methods prior to the issuance of accounts: • As part of the on-boarding process, employee identity should be verified through the use of government-issued identification documents. • As part of the visitor verification process, where visitors may be provided with system access, visitor identity should be verified through the use of government-issued identification documents. 4.1.1.2 Create Unique IDs and Authenticators Each system user is to be provided with an identifier (also known as identity or ID) and an authenticator such that they can uniquely and individually access the system: • Identifiers must be unique to the individual but can be common across systems. • Authenticators must be unique to each individual and to each systems; however a master authenticator may be used to 9

access individual system authenticators (a single sign-on system). 4.1.1.3 Securely Distribute IDs and Authenticators The identifiers and authenticators associated with each account must be distributed in such a manner as to ensure they are delivered only to the personnel to whom they are assigned: • Identifiers are to be distributed in a manner that eliminates repudiation of receipt. • Authenticators are to be distributed in a manner that protects their secrecy and eliminates repudiation of receipt. 4.1.1.4 Provide Lifespan Management for Authenticators Over time, authenticators can become known (if they are first factor authenticators), or inactive/damaged/lost (if they are second factor authenticators) and so must be continually managed: • First factor authenticators will be provided with both a maximum and minimum lifespan and may be reset at any time at the request of the employee according to established Standards. • Second factor authenticators will be replaced at such point as they are lost, damaged, or fail. 4.1.1.5 Disable and Archive Inactive Identifiers Once an identifier is no longer required, it must be disabled to prevent its use and archived to provide for potential future investigation: • Where account access is still required by any person, identifiers will be reset. • Where account access is no longer required, identifiers will be deleted along with the account. 4.1.1.6 Revoke Inactive Authenticators Authenticators that have become known, are lost/damaged/inactive or are simply no longer required must be revoked to eliminate the potential of them being used to suborn access: • Where account access is still required by any person, first factor authenticators will be reset. • Where account access is no longer required, first factor authenticators will be deleted along with the account. • Second factor authenticators will be disassociated with accounts and returned to the inactive authenticator pool. 4.2.

maximum and minimum lifespan and may be reset at any time<br />

they are lost, damaged, or fail.<br />

4.1.1.5 Disable and Archive Inactive Identifiers<br />

prevent its use and archived to provide for potential future<br />

investigation:<br />

deleted along with the account.<br />

4.1.1.6 Revoke Inactive Authenticators<br />
