Dear Security Help Desk,
What can we do to secure our peer-to-peer network? What are the security issues with a P2P network?
Peer-to-peer (P2P) networking is an easy way for users to share and swap files over the Internet; some of the more popular applications include Kazaa, Napster and any IM program from Microsoft, Yahoo or AOL. While P2P is a "convenient" application, it also can open up a company's network to a number of security and liability risks. In order to mitigate risks associated with P2P networking, some organizations are implementing stronger policies and/or outright banning its use. Is P2P networking too much of a security risk for your organization? Learn more with these resources about the security issues of P2P networking.
