Cisco Systems – An Introduction to the Key Security Issues for the E-Business Economy
“With the explosion of the public Internet and e-commerce, private computers, and computer networks, if not adequately secured, are increasingly vulnerable to damaging attacks. Hackers, viruses, vindictive employees and even human error all represent clear and present dangers to networks. And all computer users, from the most casual Internet surfers to large enterprises, could be affected by network security breaches. However, security breaches can often be easily prevented. How? This guide provides you with a general overview of the most common network security threats and the steps you and your organization can take to protect yourselves from threats and ensure that the data traveling across your networks is safe.”
National Security Agency – Best Practices for Keeping Your Home Network Secure
“The cyber threat is no longer limited to your office network and work persona. Adversaries realize that targets are typically more vulnerable when operating from their home network since there is less rigor associated with the protection, monitoring, and maintenance of most home networks. Home users need to maintain a basic level of network defense and hygiene for both themselves and their family members when accessing the Internet.”
National Institute of Standards and Technology – Wireless Network Security
“Wireless communications offer organizations and users many benefits such as portability and flexibility, increased productivity, and lower installation costs. Wireless technologies cover a broad range of differing capabilities oriented toward different uses and needs. Wireless local area network (WLAN) devices, for instance, allow users to move their laptops from place to place within their offices without the need for wires and without losing network connectivity. Less wiring means greater flexibility, increased efficiency, and reduced wiring costs. Ad hoc networks, such as those enabled by Bluetooth, allow data synchronization with network systems and application sharing between devices. Bluetooth functionality also eliminates cables for printer and other peripheral device connections. Handheld devices such as personal digital assistants (PDA) and cell phones allow remote users to synchronize personal databases and provide access to network services such as wireless e-mail, Web browsing, and Internet access. Moreover, these technologies can offer dramatic cost savings and new capabilities to diverse applications ranging from retail settings to manufacturing shop floors to first responders.”
Juniper Networks & Ponemon Institute – Perceptions About Network Security
“Ponemon Institute is pleased to present the results of a study conducted to determine what IT and IT security practitioners in the US, UK, France and Germany think about how well their organizations are responding to threats against network security. Sponsored by Juniper Networks, we believe this research is important because it can provide insights from those who are dealing daily with the prevention and detection of these attacks. Specifically, what do they think about the current threat landscape and what are the most effective strategies to keep networks secure?”
Christopher Leidigh – Fundamental Principles of Network Security
“Security incidents are rising at an alarming rate every year. As the complexity of the threats increases, so do the security measures required to protect networks. Data center operators, network administrators, and other data center professionals need to comprehend the basics of security in order to safely deploy and manage networks today. This paper covers the fundamentals of secure networking systems, including firewalls, network topology and secure protocols. Best practices are also given that introduce the reader to some of the more critical aspects of securing a network.”
John E. Canavan – Fundamentals of Network Security
“I decided to write this book for several reasons. First, it is the culmination of 18 years of professional experience in the information technology (IT) field and my desire to learn more about the subject. It is also the result of research performed during my graduate studies. Most of all, however, this book is the result of teaching a network security class. For a number of years, I have taught a class aptly titled the “Fundamentals of Network Security Management.” Most of my students are professionals employed in the IT or telecommunications fields who are attending school on a part-time basis. Some are involved in the technical side of operations, while others are more involved with the business and marketing side. When I first started teaching the class I searched for a text that covered the topics that were pertinent to my students and that could be applied in their daily jobs. Since the course was an introductory level class, I wanted the book to cover the fundamentals of network security. Many good books covering computer or network security are available. However, most focus on a specific operating system. I needed a book to provide practical information that my students could apply on their jobs, rather than one focusing solely on UNIX security or NT security. No single book did so in a useful and easily understood format.”
Matt Curtin – Introduction to Network Security
“Network security is a complicated subject, historically only tackled by well-trained and experienced experts. However, as more and more people become “wired,” an increasing number of people need to understand the basics of security in a networked world. This document was written with the basic computer user and information systems manager in mind, explaining the concepts needed to read through the bype in the marketplace and understand risks and how to deal with them.”
