Hello
I am an admin for a small company of 60 users and the "Big Wig" recently discovered Skype which he uses for personal use. I was told to download this free software on all of our PC's. Since I never just go out and download something that I don't have any knowledge of I checked out the website. From what I gathered this is a P2P software. I did some more digging around and am getting conflicting information about the security of this software. We do have a firewall, anti-spyware, anti-virus ect... but I still do not feel like this is a safe product to use on a business network. What do you guys think?? I would love any and all advice. Thanks in advance for any help.:)

Hi cory79.

I don't use Skype, but I was involved in a discussion here at TSG over it because it is p2p .
I found that Skype goes through a firewall without being challenged. Essentially it bypasses detection.
That seems like a weakness for security and in a business setting, I'd be darned sure it's not an important issue.
There also seems to be some issue about Skype reading and storing the Bios info and Motherboard ID

I know alot of businesses are using it to save money on their phone bills. Instead of making a phone call to one of their Regional offices, they just call them over Skype. I thought everyone would have known about Skype by now. The latest thing I am looking into though is the MagicJack.

Hi Squashman,

MagicJack only works on Windows (and maybe Mac), not on Linux to date.

The company offering MagicJack are their own CLEC, so in fact you communicate over their network.

Looks to be good for students away at college, etc. - you remember, call home for $$$ and save $$$ on the call! :)

Interesting. I have found, from my own experience, that Skype does require authorization to go thru a firewall. I hadn't followed the exchanges in detail so I found the article very interesting, but the basis of it seems correct: if you have a firewall that challenges outgoing packets, then it'll require authorization (either explicitly or via a permanent rule) when you initiate the Skype call, but not thereafter. (One of the problems is that some of the most common firewalls 'help' the user by being pre-configured with permanent rules which allow whatever programs the firewall manufacturer deems safe, sometimes in response to payment by the program manufacturer. I vastly prefer a firewall that either starts totally blank or, minimum I find acceptable, searches my drives for programs it thinks is safe & lets me approve or disapprove the list.)

My friend sent one to his son who is stationed over seas. Saving them a ton of money on phone bills.
