A method and apparatus for providing network security using security labeling is disclosed. The method includes comparing first security level information and second security level information, and indicating processing to be performed on the packet based on the comparing. The first security level information is stored in a security label of a packet received at a network node, while the second security level information is stored at the network node.

The invention relates to a closed loop type network security supervision method and system for a security threat event. When a security detection module finds the security threat event and needs to notify, a corresponding state tag code is set and recording is carried out; alarm information is generated and sent to an alarm contact; the alarm contact disposes and submits the event state tag code and modifies the event state tag code into a to-be-audited state; a network security supervision mechanism audits to confirm whether the event state tag code is effectively disposed; if no, the networksecurity supervision mechanism continuously notifies to rectify; and events disposed by adopting network access control are directionally tracked, and other effective disposes are completed accordingto flow. According to the invention, the particularity of network security is combined; a closed loop of finding, notification, dispose and tracking management is constructed for the security threatevent; the security threat event is continuously tracked so as to ensure closed-loop dispose and correct repair of the event; process data can be quantized and can be examined; a current situation anda dispose condition of the security threat event of a subordinate supervision mechanism are effectively quantized; network security supervision means are increased; and the network security supervision efficiency and the jurisdiction security level are continuously promoted.
