Authenticate identity during each interaction
Authenticate client or third party identities during each interaction to confirm the person owns the record they are trying to access. This control is supported by the National Identity Proofing Guidelines and the Trusted Digital Identity Framework. The three types of authentication are:
- something you know, such as a password
- something you have, such as an ID badge or cryptographic key
- something you are, such as a fingerprint or other biometric data.
Why this countermeasure matters
Whole-of-Government policies require a high level of confidence in the identity of individuals when providing government services and payments.
Providing services to someone without authenticating their identity can lead to fraudsters:
- impersonating clients or third parties to receive fraudulent payments or gain access to information
- providing false or misleading information to support a request or claim
- using stolen identity documents to support a request or claim.
How to put this countermeasure in place
Some ways to implement this countermeasure include requiring:
- all clients or providers to pass an identity authentication check prior to servicing
- staff to enter their log-on ID and password to access systems
- clients or providers to pass a two-factor authentication to access their online account
- clients to enter a unique PIN to access a mobile app
- verification through voice or facial biometrics
- the use of myGovID to authenticate an individual’s identity online
- the use of Relationship Authorisation Manager to authenticate someone acting on behalf of a business online.
How to measure this countermeasure's effectiveness
Measure the effectiveness of this countermeasure by using the following methods:
- Review authentication controls and policies to see if they conform to national guidelines and frameworks.
- Review the information threshold for authenticating an identity to discover what level of information is publicly available, such as on social media.
- Confirm the existence of reference and guidance material.
- Confirm processes are consistently applied both within channels and across channels.
- Review a sample of completed transactions to confirm correct processes were undertaken.
- Ask staff about the authentication processes to make sure they have a consistent and correct understanding.
- Undertake pressure testing or a process walk-through to confirm that you cannot get around processes.
- Identify how the requirement to authenticate identity is communicated to staff.
- Review identified cases of fraud involving the use of a false or stolen identity.
