I have been running a VPS server for the past 8 years and recently had all domains migrated to a new server(cloud) with the same provider. Previously I had an employee who managed the VPS, (only just) no major problems a few hacks now and then but nothing serious, well to my knowledge anyway.
There are approx. 55 domains, small html and wordpress sites.
CPU GenuineIntel, Intel(R) Xeon(R)CPU X5550 @ [url removed, login to view]
Version Parallels Plesk Panel [url removed, login to view] os_CentOS 5
OS CentOS 5.6 (Final)
Key number PLSK.01533857.0
System Uptime: 1 day(s) 04:53
But last week we were informed by our provider that our ip was being used to attempt access to another system. Not much information but threat of blacklist was mentioned.
I am looking for someone to assess the server configuration, mail, spam, antivirus, db configuration, wordpress installations,unusual traffic ratios, etc and work with me to make the server more reliable and secure.
I have little to nil knowledge of what is required and was hoping you may be able to assist with a plan of assessment, clean, defence and performance.
Please let me know if you are the guy for this type of work and have the time available to get this machine performing at its best.
