You may know ASP.NET, but if you don't understand how to secure your applications, you need this book. This vital guide explores the often-overlooked topic of teaching programmers how to design ASP.NET Web applications so as to prevent online thefts and security breaches.
You'll start with a thorough look at ASP.NET 3.5 basics and see happens when you don't implement security, including some amazing examples. The book then delves into the development of a Web application, walking you through the vulnerable points at every phase.
Whether a terrorist attack, fibre cut, security breach, natural disaster or traffic overload, today's networks must be designed to withstand adverse conditions and provide continuous service. This comprehensive, leading-edge book reveals the techniques and strategies to help you keep enterprise data and voice networks in service under critical circumstances. You learn numerous ways to minimize single points of failure through redundancy and backups, and discover how to select the right networking technologies to improve survivability and performance....
We use the term privacy when referring to the desire to keep communication from being seen
by anyone other than the intended recipients. Some people in the security community avoid the
term privacy because they feel its meaning has been corrupted to mean the right to know, because in
some countries there are laws known as privacy laws which state that citizens have the right to see
records kept about themselves. Privacy also tends to be used when referring to keeping personal
information about people from being collected and misused.
he security of networked computers is all about making sure that the
right people have access to the right information, and that they get it intact
without anyone listening in as the information is transmitted. To accomplish
those goals, you have to be sure that people are who they claim to be. You
also have to have a way of dealing with security breaches while—and after—
they occur, so you can figure out what is (or was) going wrong in order to
correct the problem. The difference between security on a local area network
(LAN) and security on the Internet is largely one of scale.
The “2000 CSI/FBI Computer Crime and Security Survey,” conducted in
early 2000 by the Computer Security Institute (CSI) with participation by
the San Francisco office of the Federal Bureau of Investigation (FBI),
showed that 90 percent of survey participants from large U.S. corporations,
financial institutions, medical institutions, universities, and government
agencies detected security breaches in 1999. About 70 percent of the participants
experienced breaches more serious than viruses or employee Web

Enterprise network architectures are in a constant state of flux, and due to a lack of
resources and knowledgeable security expertise, some businesses are unable to
maintain ongoing security best practices that include proactive security planning and
Because today's security threats are so stealthy, it is often difficult to impossible to
perform root cause analysis to determine how a breach or potential breach event
Every day I read e-mails and articles dealing with computer security attacks and breaches, and the
repercussions that follow. I have been getting onboard with computer security for decades, and there is
no end in sight for this effort. Each and every professional in information technology has a commitment
to keep with regard to computer security. We have, most of us, signed computing codes of conduct, and
further we have aligned ourselves with those who protect the computing resources of our respective
To see how this works, consider looking up some piece of data attached to a
DNS domain name. In our example we will look up the IP address attached to
the domain name www.nada.kth.se. We begin with a somewhat simpliﬁed de-
scription. A client that wishes to look up a name must know the address to the
“root” servers. The “root” servers are the servers located at the top of the DNS
2 The client sends a query for www.nada.kth.se to the root server, and usually
the root server only knows who is responsible for the next sub-component in the
The BACnet protocol currently uses the connectionless User Datagram Protocol (UDP)
for both Annex H and BACnet/IP communications. However, it is possible that Trans-
mission Control Protocol (TCP) transport will be utilized for some service in the future,
and so threats specific to TCP have been included. Even if TCP/IP is never used as part
of the BACnet protocol, it still can be used to gain access to the building control system
web servers, get access through the corporate firewall, and be used for denial of service
attacks on the external network on which the BCS may depend.
IDC believes that multilayered security solutions offer enterprises a cost-effective and
multifaceted alternative to enhance overall infrastructure security posture and improve
customer and management confidence levels. By adopting an overwatch architecture
with additional security layers that detect and remediate threats that have bypassed
perimeter and content security, security managers can reduce the risks of breaches
and infections associated with existing unknown security gaps and vulnerabilities.
If we lived in a static world, developing effective solutions for known attacks might be
achievable over time. However, in today's complex cyber business environment, there
is no static state. Too often, attackers are ahead of the curve, continually innovating
effective attack strategies and schemes, while security professionals and enterprise
IT continue to struggle to keep pace with malicious developments.
Today's enterprise threat environment has evolved and exploded into an assortment
of blended attack vectors that effectively work in concert to breach existing security
Network infrastructure visibility is a crucial component of an overall enterprise security
posture. As discussed earlier, enterprise security infrastructures generally comprise a
number of point security solutions. Achieving an overall integrated view of an
enterprise's security activities and status is often a difficult and time-consuming task.
Enterprise IT and security professionals are being challenged to defend against
increasingly complex cyber attacks on their businesses. However, in most cases, they
still rely on the tools of "yesterday" to get the work done. In many cases, due to the
restraints of reduced security-oriented staff and limited and tight budgets, security
managers continue to use what they have always used, even if it isn't totally effective.
The level of threat posed by a terrorist group is determined in large part by its ability to build its organizational capabilities and bring those capabilities to bear in violent action. As part of homeland security efforts, technology systems play a key role within a larger, integrated strategy to target groups
The IT profession has experienced dramatic changes
within the past 10 years and the pace is not slowing.
Just within the past year, we have seen:
• Vista, a new OS from Microsoft
• Leopard, a new OS from Apple
• A new certification program from Cisco
• A new certification program from Microsoft
• A record year for data security breaches
• An increase in the importance of balancing IT
and business skills
Hacking, cracking, and cyber crimes are hot topics these days and will continue to be for the foreseeable future. However, there are steps you can take to reduce your organization's threat level. The first step is to understand what risks, threats, and vulnerabilities currently exist in your environment. The second step is to learn as much
as possible about the problems so you can formulate a solid response. The third step is to intelligently deploy your selected countermeasures and safeguards to erect protections around your most mission-critical assets.
The Mzansi Account is the result of a banking industry initiative to provide a standard bank account,
which is affordable, readily available and suits the specific needs of the previously unbanked com-
munities. This initiative is a requirement of the Financial Sector Charter, which requires banks to
make banking more accessible to the nation and, specifically, to increase banking reach to all com-
The scope, complexity, and pervasiveness of computer-based and controlled
systems continue to increase dramatically. The consequences of these sys-
tems failing can range from the mildly annoying to catastrophic, with serious
injury occurring or lives lost, human-made and natural systems destroyed,
security breached, businesses failed, or opportunities lost. As software
assumes more of the responsibility of providing functionality and control in
systems, it becomes more complex and more significant to the overall system
performance and dependability...
But just as the earliest automobiles looked like horse carriages, reﬂecting outdated assump-
tions about the way they would be used, information resources on the Web still resemble their
physical predecessors. Although much information is already in structured form inside databases
on the Web, such information is still ﬂattened out for presentation, segmented into “pages,” and
aggregated into separate “sites.
