I have a question for you: How much costs (in average) the logs storage (1 year, 3, and most important 7 years).
The reason of my question is that I am trying to convince my client to get rid of some usefull IDS/SIEM rules, and even to stop collecting some events.
Besides the noise they generate, they cost a lot of money to store them for a long time.
So, if you have some data, or some links please share them with me/us.
Thank you very much!
P.S. If you have data about how much space different events/logs take ... it would be welcome
