The computer network equipment generally placed in the computer room within the building, the building usually have anti-cloud-to-the lightning protection, under normal circumstances, the network equipment has been building against lightning directly stroke lightning protection facilities, in lightning non-exposed areas, which suffer from the possibility of cloud-to relatively small, and then subjected to a higher probability of lightning, so the computer network system to consider more of a lightning and the lightning invasion of the shielding. through the power lines and communication lines and other potential invasive risks lightning surge protector installed, to prevent or mitigate the impact of lightning on the network. Computer network systems power is not an independent power supply system, still under power lines enter the room, in theory, may suffer Thunderstorm for power lines and lightning. If the cloud-to hit the high voltage line through the transformer coupled to the low end, through the computer for computer network intrusion system power equipment; the same cloud-to-voltage lines may also be hit or over-voltage sensing. No matter what kind of circumstances caused by lightning over-voltage power lines are computer network system equipment would cause devastating damage.
Deceived the user should first local police, and police reports by e-mail or mail sent to the four companies, which report will be analyzed and the results of correlation analysis provided to the police. International Criminal Police Organization to cooperate with the countries concerned to coordinate fight against "down payment fraud" crime plan. Microsoft Europe, Middle East and Africa, Chief Security Adviser Luo Jie Ha Bi Er said that the survey shows that these fraudulent criminal activity is implemented by a small number of criminal gangs. The use of free email services, the implementation of the cost of such fraud, criminal activity is very low, very handsome profit.
