While organizations and governments have invested a considerable amount of time and effort in securing their network s connection to the Internet, the addition of a wireless extension anywhere within the existing internal network will undoubtedly create a potential backdoor into the target wired network (see Figure B.1). Due in part to the fact that wireless LANs are used primarily for convenient access to the internal wired network (intranet), wireless access points are usually placed behind the network s demilitarized zone (DMZ). By gaining access into the wireless access point, an attacker can essentially plug into the wired network as an internal user, bypassing the target network s firewall, intrusion detection system (IDS), or any other standard security mechanisms designed to prevent intrusion through the most common port of entry the Internet. Figure B.1 demonstrates a potential backdoor into a WLAN.

ated before World War I, the new central bank was the product of several years of discussion between legislators and Wall Street bankers, some of whom were foreign born. As a result, it was vulnerable to criticism from those who thought bankers were selling out to foreign interests. After World War I the country was thrust into a new international role and the connections only incensed critics further. Soon, the harshest critics would see conspiracies around every corner and a banker beneath every bed. In the 1920s, these critics were both loud and marginal at the same time. The press acknowledged them, but were they a real force in public affairs Many of these ideas were directly inherited from the Progressives. Others were inherited from agrarian groups whose appeal became timely in the 1920s. Although the decade was best known for the booming economy, it was also characterized by anti-Semitism, xenophobia, Prohibition, and rough years for farmers. America was divided on many issues, but it was the general sense of prosperity symbolized by the stock market that united many disparate groups. The boom of the 1920s was mainly an urban affair. Outside the urban areas, the suspicions about and distrust of Wall Street and the cities were on full display. The problem for many agrarians was that uniting over a common cause was neither easy nor apt to be readily noticed outside the Midwest. While Progressives in the 1920s all shared a common political tradition, they also shared a common intellectual one as well. Most supported Theodore Roosevelt and his Bullmoose Party in the 1912 elections and after his loss supported many of Woodrow Wilson s policies. But a common thread among them was the crusading lawyer Louis Brandeis, who in the 1920s was sitting on the Supreme Court, having been appointed by Wilson in 1916. His 1914 book Other People s Money had become the bible for the Progressive movement, showing how bankers used deposits to insinuate their way onto corporate boards, seizing a power that was not rightfully theirs. The Morgan banking empire was the motivating force behind the book, and the Progressives had

is incremented each time a valid entry is found, and the valid entry is copied into the array at the position of the counter. This way, all valid entries are moved to the beginning of the array.

The first of these patterns would match any string containing any one of the sub-strings MasterCard , Visa or AmEx . The second pattern matches inputs that include cat s bowl or dog s plate . If you are matching a pattern with alternatives, you probably want to know the actual match. After a successful match, the Perl core variable $& is set to the entire string matched; you could use the value of this variable to identify the chosen credit card company. Literal patterns, even patterns with alternative literal sub-strings, are usually insufficient. Most applications require matches that specify the general form for a pattern, but which allow variation in detail. The character . matches any character (if you want to match a literal period character, you need \.). You can define character classes sets of characters that are equally acceptable. For example, the character class defining vowels is:

On some systems, especially modern Linux distributions, there s a page containing glue code for programs to use when calling system calls and coming back from signals. You can see it listed as [vdso] on /proc/ <pid>/maps. This page contains code that has proved to be useful on some exploits, and some systems still map it always at a fixed location, which converts it into a very interesting target for ret2syscall or more generally ret2code attacks. More information about this so-called linuxgate.so artifact can be found in http://www.trilithium.com/johan/ 2005/08/linux-gate/. Bear in mind that depending on the distribution, [vdso] may be mapped non-executable.

For the discrete Gilbert Elliot model illustrated in Figure 7.3, the duration that a wireless channel stays in a state before transiting to the other state is a geometrically distributed random variable that indicates the integer number of discrete time slots. At the beginning of each time slot, let the transition probability from good state to bad state be given by . Similarly, the transition probability from bad state to good state is given by . Then the average duration that a wireless channel stays in the good and bad states is denoted by 1 and 1 , respectively. By solving the balance equations of two-state Markov chain, we can determine the stationary probabilities of the good state g and bad state b as follows: g + b = 1, g = b , g = , + b = . + (7.2)

If we wanted to recreate the size example shown earlier when using <xsd:pattern> by using the enumeration facet, we could do so using code like the following:
