Network attacks have resulted in the loss of sensitive data and significant network downtime. When a network or the resources in it are inaccessible, worker productivity can suffer, and business income may be lost. Attackers have developed many tools over the......

The first printing of the First Edition appeared at the Las Vegas Interop in May, 1994. At that
same show appeared the first of many commercial firewall products. In many ways, the field has
matured since then: You can buy a decent firewall off the shelf from many vendors.
The problem of deploying that firewall in a secure and useful manner remains. We have
studied many Internet access arrangements in which the only secure component was the firewall
itself—it was easily bypassed by attackers going after the "protected" inside machines.
Australia has national interest and humanitarian reasons for providing aid to Viet Nam. Its centrality in the region means that a stable and growing Viet Nam will be good for regional cooperation, security, trade
and prosperity. The prospects for poverty reduction are good. Australia has a valuable contribution to make by building on the
successes and lessons learned from the past 10 years of bilateral development cooperation.
The purpose of this book is to answer those questions, from the point of view of people who want to use Java, but want to do so reliably, securely and safely. That makes this book different from much recent writing on Java, which focuses, perfectly legitimately, on how a Java system can be broken into and how to avoid those dangers. On the contrary, this book focuses on how Java can be made secure and how to exploit its strengths. The goal is to provide practical help to the various groups involved in making a Java-based application or Web site into an industrial-strength commercial proposit.
Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.
This is the first of four reports assessing the deployment
of technologies (i.e., equipment and procedures) by the Federal
Aviation Administration (FAA). This assessment of the
1997–1998 deployment of technologies by the FAA to improve
aviation security was conducted by the Panel on Assessment
of Technologies Deployed to Improve Aviation
Security under the auspices of the National Research Council
(NRC) Committee on Commercial Aviation Security.
This is the first part of a four-part assessment that will be
completed in fiscal year 2001.
Reports on Computer Systems Technology
The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST) promotes the U.S. economy and public welfare by providing technical leadership for the nation’s measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analysis to advance the development and productive use of information technology.
Focusing on network security, this text provides a systematic and practical approach to assessing threats to the network and implementing workable and effective security measures to avert them. Coverage ranges from physical network security to data theft and viruses. The CD-ROM includes evaluation and demonstration of commercial firewalls, intrusion detection software, a variety of hacker tools for testing your own network and much more.
Network connections should therefore be protected, at a level based on the
risk. The assumption must be that the connecting parties are to a certain degree
hostile and have to be strictly constrained to the access for which the connection
was agreed. The connecting parties will, after all, have their own security
policies and risk management philosophies, and these may vary considerably.
Each security management domain will need to apply stringent logical access
controls, and should strongly consider using firewalls and related technologies to
defend their 'perimeter'....

Linux has come a long way in a short time. Computing itself is still relatively young by any
standard; if the era of modern computing started with the invention of the microchip, it’s still
less than 50 years old. But Linux is a youngster compared even to this; it has been around for
only 15 of those years.
In that brief time span, a student’s personal project has grown to where it now runs many
computers throughout the world.
Linux is a member of the large family of Unix-like operating systems. A relative newcomer
experiencing sudden spectacular popularity starting in the late 1990s, Linux joins such wellknown
commercial Unix operating systems as System V Release 4 (SVR4), developed by
AT&T (now owned by the SCO Group); the 4.4 BSD release from the University of California
at Berkeley (4.4BSD); Digital Unix from Digital Equipment Corporation (now Hewlett-
Packard); AIX from IBM; HP-UX from Hewlett-Packard; Solaris from Sun Microsystems; and
Mac OS X from Apple Computer, Inc....
Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes
that wish to communicate without any fixed infrastructure and pre-determined
organization of available links. The nodes in MANET themselves are responsible for
dynamically discovering other nodes to communicate. Although the ongoing trend is to
adopt ad hoc networks for commercial uses due to their certain unique properties, the
main challenge is the vulnerability to security attacks.
Over the last ten years, the impact of wireless communications on
the way we live and do business has been surpassed only by the impact
of the Internet. Cell phones, pagers, and wireless Personal Digital
Assistants (PDAs) have become so commonplace in our lives that it is
easy to forget that ten years ago, they were a rarity.

The money market is traditionally defined as the market for financial
assets that have original maturities of one year or less. In essence, it is
the market for short-term debt instruments. Financial assets traded in
this market include such instruments as U.S. Treasury bills, commercial
paper, some medium-term notes, bankers acceptances, federal agency
discount paper, most certificates of deposit, repurchase agreements,
floating-rate agreements, and federal funds.
Department of Interior, major broadband Internet service providers (ISPs), banking institutions, power companies, higher educational institutes, medical organizations, and even small, family-run businesses. From experience we have found that although security as a whole is improving, knowledge growth is still needed in the public sector as well as the private sector. When we originally departed from doing strictly federal government work, we thought that it would be easier to sell this service in the commercial world. We were wrong.
