In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot.
I have a client who is considering encryption options in order to comply with a tendering requirement.
Were they to encrypt the production database then what would be a reasonable expectation forthe impact on message throughput. Or possibly more easily answered: what would be the expected impact be on I/O rate and CPU utilization. Are there any benchmarks to which could support an estimate ?
How would this compare with plan B: to use disk encryption ?
How can we make sure that the Cache userid passwords are encrypted on storage? We want to make sure that the Cache passwords cannot be decrypted - how can we ensure that?
We are currently performing encryption at the OS level but it makes storage expansion complicated. Any feedback on OS encryption vs. Ensemble? Pros/Cons. We will have CentOS7 on our new server.
