[AusNOG] Optus Hack

Tue Sep 27 13:00:16 AEST 2022

What I don’t understand (and I am not a programmer) is why there isn’t a broker setup.  In the Mainframe world normally, you would have your database on a private network that will only server a request server and serve the data that it requests to see.  I really get nervous these days when databases are not behind private networks with no public access to whatsoever.

That’s my food for thought be interested to see what goes on in the real world today but I just see this as not the most secure way to be handling any information that is stored in a database.

Is there any legal obligation to store sensitive ID information in its original form? Storing a hashed version only would be sufficient to prove the details had been collected and verify any future ID verification requirements without actually retaining the sensitive data.

Separately, should the government provide an opt in two factor ID verification service for critical services such as telco, utilities, banking, etc? There are privacy concerns, however if implemented correctly they wouldn't be collecting any further information than what they legally have access to now.

Looking at the data some fields are hashed and then repeated in the bloody clear :(

My understanding was that the data included the 100 points of ID info. Why are they retaining this? Surely after confirming the 100 points there only needs to be a record "100 points provided"=true and not retain the actual details. This goes back to only keeping the private data you need.
