This choice was made by popular demand for this date, due to the massive influx of new students and a new
paper publication. Our normal choice would be not to release two reference texts in the same month other than
for this demand, which appears to be in an extreme position at the moment as we are also receiving requests
for zip and area code directories.
Hackers play one-up among themselves. Clearly one of the prizes would
be bragging rights from hacking into my security company’s Web site or
my personal system.
Another would be that they had made up a story of a hack and planted
it on me and my co-author Bill Simon so convincingly that we were taken
in, believed it as true, and included it in this book. That has presented a fascinating challenge, a game of wits that the two
of us have played time after time as we did the interviews for the book.
derisory term meant something vastly different in its heyday. Hackers then, as now, were concerned about how things fit together, what makes things tick. Generally, many early hackers concerned themselves with understanding the nature of the telephone system, which encouraged the development of “blue boxes” and war dialers such as Ton Loc. Public bulletin boards (such as Prestel) had security flaws exposed and various services disrupted.
The methods for human identity authentication based on biometrics â€“ the physiological and behavioural characteristics of a person have been evolving continuously and seen significant improvement in performance and robustness over the last few years. However, most of the systems reported perform well in controlled operating scenarios, and their performance deteriorates significantly under real world operating conditions, and far from satisfactory in terms of robustness and accuracy, vulnerability to fraud and forgery, and use of acceptable and appropriate authentication protocols. ...
The internet is ever growing and you and I are truly pebbles
in a vast ocean of information. They say what you don’t
know can’t hurt you. When it comes to the Internet
believe quite the opposite. On the Internet there a millions and
millions of computer users logging on and off on a daily basis.
Information is transferred from one point to another in a
heartbeat. Amongst those millions upon millions of users, there’s
As humble a user you may be of the Internet, you are pitted
against the sharks of the information super highway daily.
This technical report addresses inter-networked building automation and control systems
(BAS or BCS) using the BACnet protocol [ANSI/ASHRAE, 2001]. The report deals with
threats from known sources due to communication connections to the corporate LAN and
the public Internet as well as physical threats to the building automation equipment and
attached computers. Weaknesses of the protocol, BACnet 2001, and of the physical
implementation will be examined.
Taking the network scenario of Figure 1, there will be web interfaces (routers and serv-
ers), BACnet/IP controllers (connected to interesting devices that are network accessible),
and operator workstations that may have vulnerable OS as well as configuration files and
other interesting data and resources.
The following table is adapted from a Drexel report on network security [Eisenstein et al.,
2003a] and lists known IT threats to a BACnet network connected to the public Internet.
DoS attacks are particularly malicious because although they do not provide intruders with access to speciﬁc
data, they “tie up” IS resources, preventing legitimate users from accessing applications. They are usually
achieved by hackers sending large amounts of jumbled or otherwise unmanageable data to machines that are
connected to corporate networks or the Internet. Even more malicious are Distributed Denial of Service
(DDoS) attacks in which an attacker compromises multiple machines or hosts.
Paul Graham (Hackers and Painters) has mentioned that an important read for preparing to start your own business is How To Win Friends and Influence People. I'm happy to report that this gem from 1936 is timeless and truly life-changing. I believe Paul's reasons for the recommendation include: the importance of charisma, general rounding out one's personality, and finding ways to get responsiveness from people by making them feel good.
Hackers and malware authors have a strong motivation to keep you from finding their malicious software on
your system. If you find it, you can delete it. If you delete it, the malware author doesn’t make money—yes,
this is a for-profit business. Panda software, a respected anti-virus and anti-malware vendor, reports that from
January – March of 2006, 70% of the malware released on the Internet was trying to make money for the
authors in one way or another. For additional information on that report, visit
Seth, Gabriel and Kerstin are your average university student with a unique twist: they’re hackers. When the trio stumbles on the work of a computer criminal, they decide to report their findings to the world. Twelve hours later, the three find themse
Larger businesses in the United States have been actively pursuing information security with significant
resources including technology, people, and budgets for some years now. As a result, they have become
a much more difficult target for hackers and cyber criminals. What we are seeing is that the hackers and
cyber criminals are now focusing more of their unwanted attention on less secure small businesses.
Therefore, it is important that each small business appropriately secure their information, systems, and
Most Web application vulnerabilities rely on a hacker’s ability to input invalid data or malicious
code into the application using techniques such as the ones described. For developers with time-
to-market deadlines, it is virtually impossible to comb through code and test every possible
permutation of a malicious technique a hacker may attempt.
