Network security and security management system

摘要

Organizations rely increasingly on information technology to support their rapid growth and expansion into the global marketplace. Technologies such as the Internet, extranets, and Intranets are allowing companies to reach people and markets in a way never before imagined. However, with all of the benefits that technology brings to an enterprise, it also brings increased vulnerabilities and threats. Many companies are faced with a growing concern over the impact of disgruntled employees, hackers, unauthorized users, industrial spies, and mischievous employees exploiting and compromising their information systems and networks. Because of the very nature of an open environment, your risk of revenue and information loss is greater. At first, we explain such vulnerabilities and threats generally, then introduce the methodology and tools for network security management.
