Often a security tool does exactly what you want, right out of the box. More frequently, you need to customize the tool to fit the needs of your network structure. Network Security Tools shows experienced administrators how to modify, customize, and extend popular open source security tools such as Nikto, Ettercap, and Nessus.
This chapter covers the actual process of sitting down and designing your OSPF network. The real process of putting the pen
to paper and the true process behind it is covered. It is this chapter's intention to take the mystery out of designing any type of
network. The concepts and steps discussed have universal application whether your network is BGP or OSPF; of course, the
latter is emphasized. Chapter 6, "Advanced OSPF Design Concepts," covered many of the commands necessary for
This paper is the second in a three-part series of white papers, each of which focuses on a functional area of
securing your network. As introduced in the first installment, network security should be implemented throughout
your entire network. Take a layered approach and introduce security at every layer possible. This second
paper will suggest steps to secure your Router, Firewall, and Virtual Private Network (VPN) Concentrators.

A network will make your life easier, and Home Networking All-In-One Desk Reference For Dummies makes it easier to create one.
Welcome to Network Access Control For Dummies. It's a scary networking world out there, and this book
provides you with a working reference for understanding and deploying what type of network access
control (NAC) is best suited for your network and you.
Because you're holding this book, you already know that security issues exist out there — and you've
probably, maybe frantically, attempted to protect the network you're responsible for from the scenarios that
get printed on the front page....
What is the challenge with converged network security? Finding the right partners to deliver a secure, reliable, converged voice and data network infrastructure — without limiting your flexibility to grow your business and extend the reach of your network — is the key. Converged network security isn’t something to be added after the fact — the need to protect your mission-critical communications systems and business applications should be considered from the very start of your converged network planning.
Unauthorized access is when an unauthorized entity gains access to an asset and has the
possibility to tamper with that asset. Gaining access is usually the result of intercepting
some information in transit over an insecure channel or exploiting an inherent weakness in
a technology or a product.
Getting access to corporate network resources is usually accomplished by doing some
reconnaissance work. Most likely, the corporate network will be accessed through the
Internet, tapping into the physical wire, remote modem dial-in access, or wireless network
Privacy Enhanced Mail (PEM) was the ﬁrst serious eﬀort to secure Internet
mail. The Internet Resources Task Force (IRTF) Privacy and Security Research
Group (PSRG) did the initial design. The Internet Engineering Task Force (IETF)
PEM Working Group continued development for three years, resulting in a four-
part Proposed Internet Standard published in early 1993    . PEM
is a broad standard suite, it provides encryption, authentication, message integrity
and key management. PEM supports both symmetric and asymmetric (public-
key) key management schemes.
What does a typical BCS network look like? Most installations today have a dedicated
BCS network with centralized control via an operator’s terminal in the facility manager’s
office. There is no Internet (or LAN) connection, and thus no IT threat. However, the
trend today is toward greater connectivity to enable new services, convenience, and
savings on infrastructure costs. Newer buildings have network connections to the Inter-
net. But even so, most BCS networks still have few resources that are of value to the
Q: What type of authentication system does the OS (Security Kernel) determined who is allowed access to a resource
Q: What access control model helps fight “authorization creep”
Q: Biometrics are an example of “What you ____”
Q: What is a better security model, network based or host based? Justify your answer.
This is a book about hacking. It’s not a novel about a set of elusive
cyberpunks, it’s a do-it-yourself manual. Are we trying to tell you how
to break into other people’s systems? No, we’re trying to help you
make your own systems more secure by breaking into them yourself.
Yes, this has the side effect that you might learn how to break into
someone else’s system as well, and therein lies much of the controversy

Administering Cisco QoS in IP Networks discusses IP Quality of Service (QoS) and
how it applies to Enterprise and Service Provider environments. It reviews routing
protocols and quality of service mechanisms available today on Cisco network
devices (routers, switches, etc.).This guide provides examples and exercises for a
hands-on experience to give you the background and necessary details to implement
these capabilities in your network today.
While I was writing this document a book "Hack Proofing Your Network" was released. I haven't been able to read it (dunno if its in print yet, and besides - everything takes a while to get to South Africa). I did however read the first chapter, as it is available to the public. In this chapter the author writes about different views on IT security - hackers, crackers, script kiddies and everything in between. I had some thoughts about this and decided that it was a good starting point for this document....

Today's networks incorporate more security features than ever before, yet
hacking grows more common and more severe. Technology alone is not the
answer. You need the knowledge to select and deploy the technology
effectively, and the guidance of experts to develop a comprehensive plan that
keeps your organization two steps ahead of mischief and thievery. Active
Defense: A Comprehensive Guide to Network Security gives you precisely the
knowledge and expertise you're looking for. You'll work smarter by day, and
sleep easier by night....
