I wonder if anyone might be able to tell me whether it’s currently possible to implement data pseudonymization with graylog. Specifically what we’d like to be able to do is to retain log messages with personally identifiable information for a set period, say 6 months, and then pseudonymize the data after that.
I saw this thread where someone seems to have the same question but I don’t think that answers whether it’s possible to hash the logging data after a set period (only that it is possible to hash the data as it comes in). As far as I can tell I don’t believe this would be possible with pipelines?
Would appreciate any advice from people dealing with the same issues at the moment.
