Re-securing my network after allowing support tech access

So I had to allow Tech Support access to my computer to solve a problem with remote connecting to my security camera system. They used ShowMyPC and CheckMyPorts to look around even hough I insisted that the problem wasn’t with the network. It ended up being a password problem and I only found that out by calling back and talking to a different Tech.

Anyway they made me really nervous while in my router because they spent quite a bit of time looking at my network passwords and setup information. I will be changing all the passwords which really are a pain in the neck. I’m also concerned because he was adding IP address to the security settings. Can he gain access to my computer through some sort of back door even if I change the passwords?

I deleted the new programs after the guy was out, but I’m worried if there is anything left over that wasn’t deleted. How do I know for sure?

They just spent too much time changeing things that never was a problem.
 
well for starters just what company was this tech services from exactly?if its a reputable company you likely have no worries.if unsure i would change my passwords as well as my router password.

Well its Lorex, but they pass it off to India and I just don’t have a lot of faith for anything going outside the country. They've been on my computer a few years ago when I first bought the system, but they never took so much time in my router before. They just went straight to what they need to verify in the settings. This time was a little different.

Thanks, after redoing all the passwords I have to do this with the tech guy all over again because I lost all my port forwarding by accident. :(

I'm not sure if I need to worry about redoing the wireless portion because if I believe someone would have to be within range to use that information, but I'm not sure.
 
Just make sure that if your not using the WIFI turn it off. If you are using it set at least a 12 digit password, alpha,numeric,symbol and use WPA2 AES only. No TKIP crap. All modern hardware built sometime after '07 will support AES. I saw your other post about port forwarding. I guess you have to use port 80? If so I would check out Untangle. May be above and beyond and over your head, but if you learn about it, by an old computer or Dell server it will be well worth it for added security.

Thanks, I did a search on line to see about port 80 and found a site that lists every common port listed by manufacture for just about everything including Lorex I'll tell you, I went through the port listings and I just don't know if there is a port number that's not being used.
I'll read up on "Untangle" see what its all about.

Wireless security has nothing to do with his issue, it just helps to make it more difficult to hack your network when they are in the vicinity, but if they installed something on the computer, it doesn't make a difference.

Enabling the firewall and NAT on your router is much easier than setting up a computer as a dedicated firewall.

Thanks for verifying that. I thought that may be the case and I don’t think my neighbors are too computer savvy to figure that out. LOL

Although my daughter somehow figured it out when she was like 15 I think. She was in trouble for something so I grounded her from the computer by locking her out in router, but I noticed that she was pretty quiet in her room.

After a few hours I decided to check on her and found her using the computer even after locking her out of the network. When I checked her computer, I found that she was tapped in to the neighbors across the street.

I called the neighbors and told them they needed to secure their wireless and then my daughter wasn’t so quiet after that. LOL :eek:
 
Everyone needs to secure their router's WIFI. It has nothing to do with tech access and crap like that, but if your concerned at all about security at all you will heed my advice.
