Posted: Sun Aug 01, 2010 11:11 am Post subject: Concerned with NAS & Router attacks.
I've recently purchased a NAS, QNAP that I have given internet connection through DYNDNS since I'm on a dynamic IP setup on cable.
In less than 1 day, I have had 6 attack attempts - leading to banning the attacking IP on the NAS. The setup is so that if 5 attempts with the wrong password has been entered, the IP gets blocked for 60 minutes.
This triggered my worries and I started looking at my system in general.
I have a DLink DIR-655 which might not be the greatest out there.
On all systems (4 computers) I run Zonealarm Extreme (I guess some of you won't like ZA), but it's been my companion for 8 years...
1) Of course there are several posts on Blocked incoming TCP, UDP, ICMP. on the Router. It starts even the second I turn on the router from a reset. Some from China and Russia.
Then there are outgoing TCP & ICMP that is worrying me. I have several programs updating and upgrading. So some I can trace to the program, but most of them I can not.
Is there any way I can figure out wich program - or service, that is trying to send out the packet to the odd IP??
2) My Router might not be the brightest, and my needs are for home use / small office. But are there any routers where I can import IPTables and basically block out IP for a bunch of countries that are bad? My router only allows manual input through GUI.
3) My NAS is running on port-forwarding on the router for ports 8080, 80, 21 (ftp) etc but only on these ports. Even so, I have received 6 attacks. Is this normal? As I mentioned I use DYNDNS. At the moment I'm questioning the security for the NAS.
4) Is it safer storing files I want to share on a third party Online system like Sugarsync? Or similar??
