In some case, single network vulnerability may be safe, or in some single act does not constitute a threat, but in the complex network connection, the attackers can make use of network-related vulnerabilities to exploit, and gradually improve their own power, and ultimately achieve the purpose of controlling objectives the machine or service.

The model collects the network vulnerability, analyzes the vulnerability relation, references network configuration and topology, simulates the produce of the exploitation state change, builds exploit graph, analyzes the key exploit queue and constructs assessment of network vulnerability, which provides a useful evidence and guidance for making risk decision.

The method identifies the correlation graphs to be integrated through alert relativity, and reasons out missing alerts by analyzing network vulnerability and exploit.

A kind of framework was introduced for realtimely analyzing network vulnerability.

The evaluation of network vulnerability was the first-line task for network security issue.

In this paper,a space with a closed image of a locally compact metric space is obtained if and only if it is a Frchet space with a point-countable weak-compact k-network,it is a new characterization of closed images with locally compact metric spaces by means of weak-compact k-networks.

The Localization Technology Based on TDOA for Wireless Sensor Network Nodes;

According the speciality of wireless sensor network technology and alarming in intelligent home,we designed an alarming system based on wireless sensor network technology,built the structure picture of alarming system,and designed the network node and software of the alarming system.

Such design enhances the flexibility of the system and improves the reliability of the network nodes.

The difference between the process pinch and network pinch has been analyzed.
