What security concerns should I be worried about when sharing folders over my network? 

by on January 2, 2011

Q: I’m looking to share folders and/or drives between computers on my home network. I have a router for my home network with both wired and wireless connections.

As I understand it the router offers some level of security just by the fact that computers on the internal network send traffic using an internal IP address while traffic on the outside of the network use a different IP prefix (192 vs anything else). Traffic originated from a computer on the internal network is allowed to pass out from the router, but unsolicited traffic from the outside is not routed to my internal network… for the most part…. barring any specials settings the router has setup for port forwarding… My understanding here is not great.

1. Is my basic understanding of router protection correct?
2. If I start to share folders on my internal network (computer1) whats my security concerns? If the router is blocking unsolicited traffic, then wheres my gap?
3. I also have firewall software on my computers (computer1 & 2). Is there something I can do with the firewall software to cover the gaps in router security (see question 2)?


How can I share large files with my friends? 

by on December 28, 2010

Q: I want to give public access to one folder in my my hosting package. I want to share and receive large files with some friends but I don’t want them to have access to the rest of my hosting. I don’t want them to have access to all of my other files. Is there a way of doing this or do I have to have a separate hosting package and share the ftp login and password with them? Maybe an index page that has an upload button?
