"A solve-it-yourself mystery that will draw you in with entertaining, yet realistic scenarios that both challenge and inform you." --Tim Newsham, security research scientist, @stake, Inc.

Malicious hackers are everywhere these days, so how do you keep them out of your networks? This unique volume challenges your forensics and incident response skills with 20 real-world hacks presented by upper-echelon security experts. Important topics are covered, including Denial of Service, wireless technologies, Web attacks, and malicious code. Each challenge includes a detailed explanation of the incident--how the break-in was detected, evidence and possible clues, technical background such as log files and network maps, and a series of questions for you to solve. Then, in Part II, you get a detailed analysis of how the experts solved each incident.

Excerpt from "The Insider":

The Challenge:

Kris, a software company's senior I.T. staffer, got a call from the helpdesk....Users were complaining that the entire contents of their inbox, outbox, and deleted items folders had completely disappeared....The following Monday, Kris found that the entire Exchange database had been deleted....The attacker sent an email from a Yahoo! account taking responsibility for the attacks....The e-mail had been sent from a machine within the victim's network. Kris brought in an external security team who immediately began their investigation...In addition to gathering physical security logs, Microsoft Exchange logs, and virtual private network (VPN) logs they interviewed key people inside the company....

The Solution:

After reviewing the log files included in the challenge, propose your assessment--whendid the deletion of e-mail accounts begin and end, which users were connected to the VPN at the time, and what IP addresses were the users connecting from? Then, turn to the experts' answers to find out what really happened.

Hailed as "a chilling portrait" by The Boston Globe and "a crafty thriller" by Newsweek, this astonishing story of an obsessive hacker promises to change the way you look at the Internet forever.

At Large chronicles the massive manhunt that united hard-nosed FBI agents, computer nerds, and uptight security bureaucrats against an elusive computer outlaw who broke into highly secured computer systems at banks, universities, federal agencies, and top-secret military weapons-research sites. Here is "a real-life tale of cops vs. hackers, by two technology writers with a flair for turning a complicated crime and investigation into a fast-moving edge-of-your-seat story" (Kirkus Reviews, starred). At Large blows the lid off the frightening vulnerability of the global online network, which leaves not only systems, but also individuals, exposed.

This new edition of the hacker's own phenomenally successful lexicon includes more than 100 new entries and updates or revises 200 more. This new edition of the hacker's own phenomenally successful lexicon includes more than 100 new entries and updates or revises 200 more. Historically and etymologically richer than its predecessor, it supplies additional background on existing entries and clarifies the murky origins of several important jargon terms (overturning a few long-standing folk etymologies) while still retaining its high giggle value. Sample definition hacker n. [originally, someone who makes furniture with an axe] 1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary. 2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming. 3. A person capable of appreciating {hack value}. 4. A person who is good at programming quickly. 5. An expert at a particular program, or one who frequently does work using it or on it; as in `a UNIX hacker'. (Definitions 1 through 5 are correlated, and people who fit them congregate.) 6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example. 7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations. 8. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence `password hacker', `network hacker'. The correct term is {cracker}. The term 'hacker' also tends to connote membership in the global community defined by the net (see {network, the} and {Internet address}). It also implies that the person described is seen to subscribe to some version of the hacker ethic (see {hacker ethic, the}). It is better to be described as a hacker by others than to describe oneself that way. Hackers consider themselves something of an elite (a meritocracy based on ability), though one to which new members are gladly welcome. There is thus a certain ego satisfaction to be had in identifying yourself as a hacker (but if you claim to be one and are not, you'll quickly be labeled {bogus}). See also {wannabee}.

Privacy and Copyright protection is a very important issue in our digital society, where a very large amount of multimedia data are generated and distributed daily using different kinds of consumer electronic devices and very popular communication channels, such as the Web and social networks. This book introduces state-of-the-art technology on data hiding and copyright protection of digital images, and offers a solid basis for future study and research. Steganographic technique overcomes the traditional cryptographic approach, providing new solutions for secure data transmission without raising users' malicious intention. In steganography, some secret information can be inserted into the original data in imperceptible and efficient ways to avoid distortion of the image, and enhance the embedding capacity, respectively. Digital watermarking also adopts data hiding techniques for copyright protection and tampering verification of multimedia data. In watermarking, an illegitimate copy can be recognised by testing the presence of a valid watermark and a dispute on the ownership of the image resolved. Different kinds of steganographic and watermarking techniques, providing different features and diverse characteristics, have been presented in this book. This book provides a reference for theoretical problems as well as practical solutions and applications for steganography and watermarking techniques. In particular, both the academic community (graduate student, post-doc and faculty) in Electrical Engineering, Computer Science, and Applied Mathematics; and the industrial community (engineers, engineering managers, programmers, research lab staff and managers, security managers) will find this book interesting.

Serious Cryptography is the much anticipated review of modern cryptography by cryptographer JP Aumasson. This is a book for readers who want to understand how cryptography works in today's world. The book is suitable for a wide audience, yet is filled with mathematical concepts and meaty discussions of how the various cryptographic mechanisms work. Chapters cover the notion of secure encryption, randomness, block ciphers and ciphers, hash functions and message authentication codes, public-key crypto including RSA, Diffie-Hellman, and elliptic curves, as well as TLS and post-quantum cryptography. Numerous code examples and real use cases throughout will help practitioners to understand the core concepts behind modern cryptography, as well as how to choose the best algorithm or protocol and ask the right questions of vendors. Aumasson discusses core concepts like computational security and forward secrecy, as well as strengths and limitations of cryptographic functionalities related to

The term 'spyware' is not well defined. Generally it is used to refer to any software that is downloaded onto a person's computer without their knowledge. Spyware may collect information about a computer user's activities and transmit that information to someone else. It may change computer settings, or cause 'pop-up' advertisements to appear (in that context, it is called 'adware'). Spyware may redirect a Web browser to a site different from what the user intended to visit, or change the user's home page. A type of spyware called 'keylogging' software records individual keystrokes, even if the author modifies or deletes what was written, or if the characters do not appear on the monitor. Thus, passwords, credit card numbers, and other personally identifiable information may be captured and relayed to unauthorised recipients. Some of these software programs have legitimate applications the computer user wants. They obtain the moniker 'spyware' when they are installed surreptitiously, or perform additional functions of which the user is unaware. Users typically do not realise that spyware is on their computer. They may have unknowingly downloaded it from the Internet by clicking within a website, or it might have been included in an attachment to an electronic mail message (e-mail) or embedded in other software. According to a survey and tests conducted by America Online and the National Cyber Security Alliance, 80% of computers in the test group were infected by spyware or adware, and 89% of the users of those computers were unaware of it. The Federal Trade Commission (FTC) issued a consumer alert on spyware in October 2004. It provided a list of warning signs that might indicate that a computer is infected with spyware, and advice on what to do if it is. This new book helps shed light on this insidious nightmare created by members of the human race to wreck havoc on the remainder.

Strong Pseudorandompermutations or SPRPs,which were introduced byLuby andRacko? [4], formalize the well established cryptographic notion ofblock ciphers.They provided a construction of SPRP, well known as LRconstruction, which was motivated by the structure of DES[6].The basicbuildingblock is the so called 2n-bit Feistel permutation (or LR round permutation) LR based F K on an n-bitpseudorandomfunction (PRF) F : K n LR (x ,x)=(F (x )?x ,x ),x ,x?{0,1} . F 1 2 K 1 2 1 1 2 K Theirconstruction consists (see Fig 1) offour rounds of Feistel permutations (or three rounds, for PRP), each round involves an application ofanindependent PRF(i.e.with independentrandomkeys K ,K ,K , and K ). More precisely, 1 2 3 4 LR and LR are PRP and SPRP respectively where K ,K ,K K ,K ,K ,K 1 2 3 1 2 3 4 LR := LR := LR (...(LR (*))...).

"The state, that must eradicate all feelings of insecurity, even potential ones, has been caught in a spiral of exception, suspicion and oppression that may lead to a complete disappearance of liberties." Mireille Delmas Marty, Libertes et surete dans un monde dangereux, 2010 This book will examine the security/freedom duo in space and time with regards to electronic communications and technologies used in social control. It will follow a diachronic path from the relative balance between philosophy and human rights, very dear to Western civilization (at the end of the 20th Century), to the current situation, where there seems to be less freedom in terms of security to the point that some scholars have wondered whether privacy should be redefined in this era. The actors involved (the Western states, digital firms, human rights organizations etc.) have seen their roles impact the legal and political science fields.
