Adding of the signing of log files whould ensure that we can show they were not modified, which would in turn provide a chain of evidence for auditors...
Are you referring to signing the CSV logs? Where would the signature appear?
Are there other requirements? If it's just that no local user can modify the logs, then a different log store such as Splunk would meet that by shipping the logs off. Something more bespoke is now possible in v5.1 thanks to the PowerShell log writer.
