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
Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.

Using certiﬁcates also opens up for the possibility of removing the key transfer
between Alice and Bob completely! This is an important feature when secure
communication is being implemented between a large number of participants. This
is because none of Bob’s ability to trust the public key he receives now depends on
whether he is actually communicating with Alice or not. His ability to trust the key
depends solely upon his trust relationship with the trusted third party.
Complacency, or the belief that "good-enough security" is all that is required, seems
to be the mind-set of many. Consequently, IT professionals may have settled for
security that isn't always effective. In the 2008 CSI Computer Crime & Security
Survey, 50% of the survey respondents reported that they suffered virus-based
security incidents. The survey results also show that one in five suffered a bot attack
in 2008. Virus security incidents have been the number 1 attack item for four of the
past five years, placing second in the other year.
Computer Software, Systems and Networks are complex growing systems. They constantly evolve and their ability to be understood and recreated as well as proven integrity issues are critical to an organizations health and security.

Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is one of the least secure forms of security.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. 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......
