Is there a process by which courts check access logs of a server to verify the data hasn't been tampered with?

Since anyone can put anything they want on their servers, it seems like a lot of evidence could be thrown out in court cases if access to that information is not strictly monitored and audited to make sure the owners aren't removing or adding data.

Does anyone know of industry-standard practices to ensure that data on servers is not being manipulated in a way to protect or harm users?
