The weaknesses of these night vision technologies in military applications are analyzed objectively and some countermeasures are proposed against these weaknesses.

In terms of the weak point and based on the microporocesses of breakdown,the statistical property is analysed, the Weibull distribution law is derived.

Design and Implementation of a Scalable Network Vulnerability Scanner System;

To analyze the network vulnerability, based on the existing study, we build a network security analysis model and propose a optimized, reversed, breadth-first algorithm to generate network attack paths, and implement an attack paths generation system.

For the classification,rate and the main threaten of the security requirement,system devices,access privilege,host connection relation and vulnerability were analyzed,and the computer network attack from the point of view that the attacker s objective was to get privilege escalation was described.

The paper studies and analyzes the weak points of the nature of Zhu Geliang in the Chinese classic book “Romance of Three Kingdoms”.

This paper presents a working model for information system security evaluation and related vulnerability management, defines some basic concepts in information security evaluation such as assets, value of assets, threat and vulnerability, and then puts forward some principles for the quantification of these concepts.
