Peer 2 Peer Networks & Your Businesses Risks

(My article)

            As most of us had heard of p2p networks and services like Kazza and Limewire what we don’t think about is that businesses are responsible for the activities on there networks.  When an employee, vendor, or customer is on your businesses network do you know what they are doing? Well for businesses like Hotels, Internet Café’s, or Public Access Points you are at highest risk for users to abuse you network. You will need to restrict cretin activities or you will find you ISP terminating your service or worse getting sued from the RIAA or MPAA. For the rest of the business owners you might want to understand the risks of lax network security and the true cost you could pay. Employees might want to surf the internet when they are at break or though out the day. This can be fine if you have web filtering. Some issues faced with web surfing at work is that if an employee downloads or installs peer 2 peer software. Other issue that most IT staff forgets to look at is users that VPN into the network also have to be monitored. The biggest problem with most peer 2 peer programs that 80%+ of the content hosted in the networks is stolen copyrighted content or viruses. This means if the owners of the content notice the download your business is liable for the theft. Other issues are viruses and Trojan programs that might compromise your Businesses data.

            Understanding the issues is the first step to preventing your business from liability. Most businesses that have avoided this issue are implementing Web filters, Network Security, and employee training. Some the of things you can do is make sure you have a firewall installed and understand the ports that peer 2 peer software uses and then you are on your way to blocking the software. Here is a list of the most popular P2P programs and networks. Hotels, internet cafes, public wireless spots, etc. should block these ports to avoid any copyright issues with the use of their internet access.

  * BearShare, Mopheus, Limewire, Gnutella
    6346 and 6347 TCP, UDP
  * Kazza, Grokster
    1214 TCP, UDP
  * Autonp, BeNapster
    6699 TCP
  * Napster, Duskter, Gnap
    6700 TCP
  * Inapster, Jnap, WinMX
    6701 TCP
  * Edonkey
    4661, 4662, 4665 TCP, UDP
  * iMesh
    4329 TCP

The above listed is just some of the most common peer 2 peer network software & ports. It is always recommended to consult you networking vendor to insure you have the most up to date software and hardware to protect you business. In addition to port blocking there are other things can do to help you businesses network. Impose network policies for all users and keep all you network protection software up to date (Anti-virus, Spyware, Ad blockers). Provide Training to you users to explain the risks of the internet. One of he biggest risks to business networks are the users and the only way to insure network safety is to make sure the users fully understand network policies. Once your users have an understanding of the risks online and fully understand there responsibilities as a network user. You are that much closer to a safe digital work place. As always most local network consulting firms can provide what I have discussed and you may need to take additional step to meet the needs of your business. With HIPPA and Sorbian Oxley there is no reason to risk liability on your company’s networks. As we see in the media every day more and more businesses have been learning the hard way about corporate liabilities.

Re: Peer 2 Peer Networks & Your Businesses Risks

One of the other things that users don't realize is that it costs money to provide internet access. My experience in university systems opened my eyes to this. So many people say... well access is free. Just because the end user doesn't pay for it doesn't make it free. The university pays for it. So along with the liability mentioned in slimjim100's article, so does the cost. And using P2P software eats up more bandwidth than anything, because you are making yourself a connecting point for all of the other peers. This eats bandwidth which in turn costs your company business. And some people wonder why they didn't get that raise this year. Hmmmmmmmmmmmm.

Re: Peer 2 Peer Networks & Your Businesses Risks

great point, lets develop that some more. How about as a penalty for getting busted running p2p at work, you forfeit your raise and it is redistributed equitably to all the people in compliance.  I like that!
