If I connect my Vista laptop to a power outlet in public, such as an airport\nterminal, library, or coffee shop, how viable is the threat from someone\ngaining access to my computer via a power-line network? If the threat is\nviable today, what is the best method of stopping it?\n\nI know many people will say this is too unlikely and that other security\nthreats are of much more concern to the average computer user, but with the\nincreasing sophistication of ripoff artists either trying to steal your\nidentity or pilfer your financial data I wouldn't assume the threat is not\nviable and not likely to increase in the future. After all, the federal\ngovernment and the defense industry utilize TEMPEST, outlining the need for\nclassified "Red Power" systems to protect computers from power-line\nmonitoring and Van Eyck monitoring as well, versus "Black Power" systems that\nare connected to the public grid. In fact, not too long ago the French were\ncaught conducting industrial espionage by tapping into a local power grid and\naccessing information via power lines.\n\nAny thoughts would be welcome. Thanks.
