Companies beware: The next big leak could be yours

SAN FRANCISCO -- WikiLeaks' release of secret government communications is a warning to the world's biggest companies: You may be next. Computer experts have warned for years about the threat posed by disgruntled insiders and by poorly crafted security policies, which give too much access to confidential data. And there is nothing about WikiLeaks' release of U.S. diplomatic documents to suggest that the group can't - or won't - use the same methods to reveal the secrets of powerful corporations.
