[Q] ROOT for Archos 50 Diamond topic

Hey guys,

i'm currently here with my Archos 50 Diamond. Because of VPN (Cisco Anyconnect) i need to root my device.
Is there a way to root a Kernel from 4. feb 2015? (Kernel version 3.10.28 Android 4.4.4)

I'm not new in rooting devices, but i have never do it completly by myself.
