Evaluated product acquisition
An evaluated product provides a level of assurance in its security functionality that an unevaluated product does not. To assist in providing this assurance, the Australian Signals Directorate (ASD) performs product evaluations through the following programs:
- ASD Cryptographic Evaluation (ACE) program, for software and ICT equipment used to protect classified information.
- High Assurance evaluation program, for software and ICT equipment used to protect highly classified information.
The Australian Cyber Security Centre (ACSC) also certifies product evaluations conducted by licensed commercial facilities, in accordance with the Common Criteria, as part of the Australasian Information Security Evaluation Program (AISEP).
For organisations seeking to procure evaluated products, the Evaluated Products List contains a list of products that have been evaluated through the ACE program or the High Assurance evaluation program while the Certified Products List contains a list of products that have been certified in accordance with the Common Criteria.
A Protection Profile (PP) is a technology-specific document that defines the security functions that must be included in a Common Criteria certified product to mitigate specific cyber threats. PPs can be published by a recognised Common Criteria Recognition Arrangement (CCRA) scheme or by the CCRA body itself. PPs published by the CCRA body are referred to as collaborative PPs.
The ACSC recognises all PPs listed on the Common Criteria website in addition to those listed on the ACSC’s website. Where a PP does not exist, an evaluation based on an Evaluation Assurance Level (EAL) may be accepted. Such evaluations are capped at EAL2+ as this represents the best balance between completion time and meaningful security assurance gains.
Organisations choosing to use Common Criteria certified products can determine their suitability by reviewing their evaluation documentation. This includes the Security Target and Certification Report.
Products that are undergoing a Common Criteria evaluation will not have published evaluation documentation. However, documentation can be obtained from the ACSC if a product is being evaluated through the AISEP. For a product that is in evaluation through a foreign scheme, the product’s vendor can be contacted directly for further information.
Evaluated product selection
A Common Criteria evaluation is traditionally conducted at a specified EAL; however, evaluations against a PP exist outside of this scale. Notably, while products evaluated against a PP will fulfil the Common Criteria EAL requirements, the EAL number will not be published.

If procuring an evaluated product, a product that has completed a PP-based evaluation is selected in preference to one that has completed an EAL-based evaluation.
Delivery of evaluated products
It is important that organisations ensure that products they purchase are the actual products that are delivered. In the case of evaluated products, if the product delivered differs from an evaluated version then the assurance gained from the evaluation may not necessarily apply.
Packaging and delivery practices can vary greatly from product to product. For most evaluated products, standard commercial packaging and delivery practices are likely to be sufficient. However, in some cases more secure packaging and delivery practices, including tamper-evident seals and secure transportation, may be required. In the case of the digital delivery of evaluated products, vendor-supplied checksums can often be used to ensure the integrity of software that was delivered.

Evaluated products are delivered in a manner consistent with any delivery procedures defined in associated evaluation documentation.

When procuring high assurance ICT equipment, the ACSC is contacted for any equipment-specific delivery procedures.
