Background:
We are Aupod, a SaaS platform providing tax services for individuals and small businesses in Australia. We are currently integrating with the ATO’s SBR systems (e.g., IITR 2025). As part of the ATO’s Digital Service Provider (DSP) Operational Security Framework, we are required to complete a security self-assessment and provide supporting documentation.

- NIST Cybersecurity Framework
Objectives:

1. Security Controls Implementation and Mapping
• - Review all requirements under the ATO DSP Operational Security Framework
