Windows Firewall ports, what to close and what needs to be left open
Posted on 2012-03-20
Hello,*thanks for all your help lately, I am so new to servers- I am a hardware guy. Let me know your thoughts on the below.
I am really nervous about the port configuration on my windows 2008 server for my website. I was told by my hosting that I need to have ONLY the following 4 ports open:
80- status - open
443- status - open
3389- status - open - will change to higher number to alleviate default configuration
* I cant see these being the only four ports open that I need.
I downloaded nMap and ran an 'intensive port scan' to identify what's open. The following ports were identified & I have since decided they need to stay open for the corresponding reasons, but I'm not sure if I'm right:
53 (this is Microsoft DNS)- status- open
587 (this is Microsoft exchange) - status -open
I still have 10 other ports listed as open, and since I'm not sure if I'm doing my research correctly, I'm posting here in the hopes that someone can guide me more definitely than a google search.
Ports still open:
88- status - open
464 - status - open
593 - status - open
808 - status - open
6001 - status - open
6002 - status - open
6004 - status - open
6005 - status - open
6006 - status - open
6007 - status - open
