open proxy server |
Also found in: Wikipedia | 0.05 sec. |
open proxy serverA proxy server that is configured so that anyone can use it. There are public access proxy servers on the Internet that are intentionally open to the general public, and there are countless private proxy servers that are unintentionally left open because they are not configured properly. Open proxy servers are widely used by spammers to send spam because the proxy hides the spammer's IP address from recipients. Spammers routinely scan the Internet for vulnerable proxy servers.

Botnets/Malicious Sources: STMP validation identifies unwanted email originating from known spam and virus sending sources, where the source can unequivocally be identified as an open proxy or a botnet, and rejects the connection accordingly. This could allow a virus writer to install open proxy or webserver software on thousands of machines, creating a hidden network that can be used to deliver more spam or host their destination sites. Three new IETF working groups were created to assist in defining these solutions in the area of existing Web replication and caching groups -- Web Infrastructure, Open Proxy, and Content Distribution Internetworking -- all of which Kaplan said he believes will "have a serious impact on the future" of the Internet. |
