Worm Storage in PACS Archives
Has anyone encountered, familiar with or inquired about utilizing WORM storage with respect to PACS Archiving? This would be considered a potential defense against ransomware and facilitate better overall data security, but wondering how it would work for a PACS Archive.

seems to me that updates to the demographics would more difficult when the study is read only. It would have to be rewritten, costing space. Still as an archive, immutability would protect against contamination or corruption. Depends on how often the data needs to change.

Those were my exact thoughts… How do we make updates?
-
how’s it work during a migration? One that say you need to prefix accessions and MRNs.

!vendor alert!
I work for Amazon Web Services and we recently released AWS HealthImaging which is an AWS managed service for medical images. One way we innovated in this space is by making every change to data versioned like a source control system. This guards against malicious (ransomware) and accidental (admin) mistakes as any change can be undone. Data can also be locked to prevent updates – happy to share more-
If you lock the data, how does it receive demographic updates?
-
You unlock, update, lock. There are usually more requirements around the ability to lock/unlock which can be addressed in various ways
-
Ah, ok, was wondering how that would be done.
Thank you for replying.
