ATO Digital Service Provider (DSP) Operational Security Framework SEC.AUTH.SSO: Enterprise single sign-on only on DPO advice and within set limits

A DSP seeks advice from the Digital Partnership Office before using enterprise single sign-on for its clients, and where SSO is implemented ensures that: disabling MFA is controlled by the DSP, not the client; encryption in transit between the client's system and the software uses an approved protocol; remember-me is limited to 24 hours; SSO tokens last at most 24 hours; tokens or temporary credentials are isolated to one device and expire once used or within 24 hours; brute force lockout applies after at most five failed attempts; credentials are stored separately from the system granting access; confirmation passwords are hashed, salted and stretched; inactive sessions time out after at most 30 minutes (15 preferred). The DSP advises the DPO that SSO is implemented and meets these standards.
