Security Issues With Dedicated Server?

Post Reply New Topic

Hey!
Im planning to run a game server from home soon.
Im worried about people packet sniffing and what not.... The game in question has allot of angry hackers on and I have a few people from that community I know will more then likely attack/hack me.
Any ideas on security with this?

To do packet sniffing, they would have to have access to someplace where they could see the traffic go by. For example, if someone at your ISP wanted to inspect all the packets, they could probably accomplish it.

There are other issues that are of far higher importance. For example, how secure is the operating system itself? If you want secure, go for OpenBSD.

A DDOS would be hard to deal with no matter what operating system you use.

I use OpenBSD for everything outside of the firewall. Linux is better than Windows, but I keep both behind the firewall.

The one problem with OpenBSD that you could run into if you have lots of concurrent users is that it is geared much more at security than at speed. However, my general impression is that because OpenBSD is leaner than Linux, it generally doesn't have too many speed problems anyway.

Just tie down everything you can.

One thing I do is limit ssh connections to a very limited number of specific user accounts.

Security isn't rocket science - just make sure you only expose needed services to the Internet.

DDoS is something the average user can't do much about - it's also likely to strain your relationship with you home ISP. It's not unheard of that ISPs cancel service for users that cause them problems.
