Unknown disk activity on 2 day old server
I'm relatively new to web servers and linux. After looking at the monitoring graphs, my VPS has had very little disk activity (nor should it as there is nothing worth visiting on the webpage). However last night while I was sleeping I notice a very regular spike in disk activity - (every 15 minutes). Is this something to be worried about? Could hackers be up to no good? Or does it simply mean DenyHosts is doing it's job properly and writing to the banned IP list?
