| Nowadays, Computing Network comes into humans' life. More and more applications, such as cooperative-work, electronic government, electronic business and on-line entertainment became a part of everyday life. Unfortunately, more and more attacks caused by virus, hacker and malicious code. These attackers threat network and the information which stored or transported through network.Although large number of security products and solutions, such as Anti-Virus software, Firewall, Virtual Personal Network, AAA servers were deployed in network, but personal computers (the most amount and end-point device) are not safe and be protected enough. Through attack those vulnerable end-point computers, hacker can get password and other secrets. Once be connected to network, a damaged computer which has been injected malicious code or be controlled by a hacker maybe become an accomplice, it will attack the whole network and result in bandwidth jam or important information loss.In order to solve the security problem of end-point computer, we embedded a secure module (Secure Chip) on mother board. This chip can store information securely and be embedded a cryptography engine and some platform Configuration Registers. With some relative protocols and middle wares, such as 802.1x and IPsec, we can build a trusted computing environment to realize information security.This paper will discuss this security module and related information security technologies and products. The main topics are below:1. Information Security and relative products.2. Secure module and trusted platform. 3. Secure module' use case on end-point and network environment.4. A Network Access Control solution using secure module. Information Security is the most aspect in IT industry, allgovernments, organizations and companies focus on information security. Although more and more secure modules have been embedded on computers, but we need more network solutions to use this chip. This essay collects and describes some use cases in information security. |
