Hi there, I have two questions:
Q1: Is it possible to turn on any encryption to the indexes of a Splunk installation other than using third party file system encryption?
Q2 : What compression do the Splunk indexes use?
Q1. What are you trying to achieve? Encryption at rest? Cryptographically signed splunk logs? Encryption at power off?
Splunk can do cryptographically signed logs - http://www.splunk.com/base/Documentation/4.2.1/Admin/Signauditevents
Crypto at power off can be handled using a crypto file system such as Luks - http://en.wikipedia.org/wiki/Linux_Unified_Key_Setup
Q2. I believe Splunk uses Zlib for compression.
