The present invention is directed to the use of a multi-tiered security architecture that includes vendor-operated global security services and policy servers able to exchange security events and mitigation measures.

The invention provides a method, a system and a network device for filtration. The method comprises the following steps: intercepting a request message transmitted by a user terminal to an internet server and extracting uniform resource locator (URL) information from the request message; determining a security level corresponding to the URL information according to the URL information; and processing the request message according to the security level. The invention solves the problems that internal memory space and CPU resources are occupied by anti-virus software installed on the user terminal, avoids the risks that malicious software can easily bypass the anti-virus software, effectively stops the propagation and the attack of the malicious software, reduces the threat of the malicious software to the user terminal and improves the network security and the user experience.

A target having a controlled utility is provided, as well as a method for changing the utility of the target. The target with controlled utility may be an electronic device, or alternatively, may be a tangible media, such as an optical disc. The controlled target has a change effecting device that is set to a first state, which allows the target to operate according to a first utility. The controlled target also has a receiver for receiving an authorization key, and logic which, responsive to the authorization key, selectively changes the change effecting device to a second state. When the change effecting device is in the second state, the target may operate according to a second utility. In one example, the controlled target has a restricted access key that was stored during manufacture, and the restricted access key is used by the logic in changing the state of the change effecting device. To change the utility of the controlled target, the controlled target is placed proximate to an activation device. The activation device may read an accessible identifier from the controlled target, and retrieve or generate an authorization key that is associated with the target. The activation device may cooperate with a network operation center or other entity to retrieve the authorization key, and to obtain approval to change the utility of the controlled target. If approved, the activation device may then send the authorization code to the controlled target.
