  • Security concepts are organized based on business needs, as opposed to tech-nological similarity. We’ve tried to focus on how these concepts relate in terms of practical business functionality. For example, network monitoring is discussed in Part 1, "Managing Security " rather than in a section on intrusion detection. For people with a technical background, this method of organization may seem strange. But one of our goals is to change the way people think about security. As we’ll say many times throughout the book, security is not a technological issue; it’s a business issue.

However, wireless networking is prone to some security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into wired networks......
