Just when you thought that network security couldn\u2019t get any tougher, Moscow-based iNetPrivacy Software has released AntiFirewall. Taking advantage of a user\u2019s ability to browse webpages (something most companies don\u2019t completely restrict), the $35 utility connects to external, anonymous proxy servers. Once connected to one of these servers, AntiFirewall users can establish FTP connections, use chat or instant messaging without restriction, and receive messages from external e-mail accounts, even if corporate security policies and firewalls would normally prevent such activities.The product also screens the user\u2019s originating IP address, providing for anonymous communication from within corporate networks. (It does not, however, support the SMTP mail protocol, so users cannot send anonymous e-mail messages.) INetPrivacy claims the utility is for users who value their privacy and freedom of communication (it could be useful, for example, in countries that restrict freedom of speech and deny access to outside news organizations and other information over the Web), but IT departments may want to be on the lookout for the tool.
