| 1 | policy (Ch 6) | NRO has signed the appropriate version of the policy | MUST | OT checks in official archive (OT manually) | ot | M | |
| 2 | policy (Ch 6) | Establish the necessary infrastructure for eduroam (set-up FLRS and exchage traffic in expeced manner) | MUST | Check RADIUS server basic configuration (OT automatically) | ot | A | |
| 3 | policy (Ch 6) | Ensure that eduroam servers and services are maintained according to the specified best practices for server build, configuration and security, with the purpose of maintaining a generally high level of security, and thereby trust in the eduroam Confederation. | MUST | Check RADIUS server version number (OT automatically/manually) OT interviews NRO (OT manually) or NRO self-assessment (NRO self) | |||
| 4 | policy (Ch 6) | Provide trustworthy and secure transport of all private authentication credentials (i.e.passwords) that are traversing the eduroam infrastructure.

| 9 | policy (Ch 6) | If dynamic RADIUS routing (see eduroam policy Section 2.1.1.2) is used by the individual SPs, then it is the responsibility of the respective NRO to ensure that appropriate F-Ticks are sent to the monitoring infrastructure, either by enforcing that the SPs send them to the monitoring infrastructure themselves, or by collecting information of the authentication events and sending these on to the monitoring infrastructure on the SP’s behalf. | REQUIRED/MUST | Check issued certificates for dynamic routing and F-Ticks from corresponding SPs (OT automatic) | ot | ? | |

| 22 | policy (not Ch 6) | Scheduled maintenance work performed by the NRO within the respective federation should be announced two (2) days in advance through the SG mailing list. For unscheduled maintenance the announcement should preferably be made 24 hours in advance. Policy says 24 working hours but 24 working hours is more than 2 days !?! A ticket on TTS should be opened by the respective NRO representative, and closed with a short comment on the performed action. | SHOULD | OT lists outages from the monitoring systems (OT automatic), then checks SG mailing list archive and TTS (OT manually).

But if eduroam OT learns of this kind of violation of the policy, NRO should loose many audit points, in order to courage NROs to report this to eduroam OT. | Tools are rather passive again. If people never report anything, they score? Or they fail? | N | S |
| 27 | policy (Ch 6) | Establish user-support service for its end users, as explained in Section 5.1 in the eduroam policy, “User Support Processes” | MUST | NRO checks that this is the case with the FTLRs & NRO verifies that this has been communicated to eduroam IdPs/SPs (NRO self) | N | S | |
