This book describes techniques to verify the authenticity of
integrated circuits (ICs). It focuses on hardware Trojan detection
and prevention and counterfeit detection and prevention. The
authors discuss a variety of detection schemes and design
methodologies for improving Trojan detection techniques, as well as
various attempts at developing hardware Trojans in IP cores and
ICs. While describing existing Trojan detection methods, the
authors also analyze their effectiveness in disclosing various
types of Trojans, and demonstrate several architecture-level
solutions.
The fastest-growing malware in the world The core functionality of
ransomware is two-fold: to encrypt data and deliver the ransom
message. This encryption can be relatively basic or maddeningly
complex, and it might affect only a single device or a whole
network. Ransomware is the fastest-growing malware in the world. In
2015, it cost companies around the world $325 million, which rose
to $5 billion by 2017 and is set to hit $20 billion in 2021. The
threat of ransomware is not going to disappear, and while the
number of ransomware attacks remains steady, the damage they cause
is significantly increasing. It is the duty of all business leaders
to protect their organisations and the data they rely on by doing
whatever is reasonably possible to mitigate the risk posed by
ransomware. To do that, though, they first need to understand the
threats they are facing. The Ransomware Threat Landscape This book
sets out clearly how ransomware works, to help business leaders
better understand the strategic risks, and explores measures that
can be put in place to protect the organisation. These measures are
structured so that any organisation can approach them. Those with
more resources and more complex environments can build them into a
comprehensive system to minimise risks, while smaller organisations
can secure their profiles with simpler, more straightforward
implementation. Suitable for senior directors, compliance managers,
privacy managers, privacy officers, IT staff, security analysts and
admin staff - in fact, all staff who use their organisation's
network/online systems to perform their role - The Ransomware
Threat Landscape - Prepare for, recognise and survive ransomware
attacks will help readers understand the ransomware threat they
face. From basic cyber hygiene to more advanced controls, the book
gives practical guidance on individual activities, introduces
implementation steps organisations can take to increase their cyber
resilience, and explores why cyber security is imperative. Topics
covered include: Introduction About ransomware Basic measures An
anti-ransomware The control framework Risk management Controls

The shocking untold story of the elite secret society of hackers
fighting to protect our privacy, our freedom, and even democracy
itself. Cult of the Dead Cow is the tale of the oldest, most
respected, and most famous American hacking group of all time.
Though until now it has remained mostly anonymous, its members
invented the concept of hacktivism, released the top tool for
testing password security, and created what was for years the best
technique for controlling computers from afar, forcing giant
companies to work harder to protect customers. They contributed to
the development of Tor, the most important privacy tool on the net,
and helped build cyberweapons that advanced US security without
injuring anyone. With its origins in the earliest days of the
Internet, the cDc is full of oddball characters -- activists,
artists, even future politicians. Many of these hackers have become
top executives and advisors walking the corridors of power in
Washington and Silicon Valley. The most famous is former Texas
Congressman and current presidential candidate Beto O'Rourke, whose
time in the cDc set him up to found a tech business, launch an
alternative publication in El Paso, and make long-shot bets on
unconventional campaigns. Today, the group and its followers are
battling electoral misinformation, making personal data safer, and
battling to keep technology a force for good instead of for
surveillance and oppression. Cult of the Dead Cow shows how
governments, corporations, and criminals came to hold immense power
over individuals and how we can fight back against them.

Able to propagate quickly and change their payload with each
infection, polymorphic worms have been able to evade even the most
advanced intrusion detection systems (IDS). And, because zero-day
worms require only seconds to launch flooding attacks on your
servers, using traditional methods such as manually creating and
storing signatures to defend against these threats is just too
slow. Bringing together critical knowledge and research on the
subject, Automatic Defense Against Zero-day Polymorphic Worms in
Communication Networks details a new approach for generating
automated signatures for unknown polymorphic worms. It presents
experimental results on a new method for polymorphic worm detection
and examines experimental implementation of signature-generation
algorithms and double-honeynet systems. If you need some
background, the book includes an overview of the fundamental terms
and concepts in network security, including the various security
models. Clearing up the misconceptions about the value of
honeypots, it explains how they can be useful in securing your
networks, and identifies open-source tools you can use to create
your own honeypot. There's also a chapter with references to
helpful reading resources on automated signature generation
systems. The authors describe cutting-edge attack detection
approaches and detail new algorithms to help you generate your own
automated signatures for polymorphic worms. Explaining how to test
the quality of your generated signatures, the text will help you
develop the understanding required to effectively protect your
communication networks. Coverage includes intrusion detection and
prevention systems (IDPS), zero-day polymorphic worm collection
methods, double-honeynet system configurations, and the
implementation of double-honeynet architectures.
The threat that is posed by 'cyber warriors' is illustrated by
recent incidents such as the Year 2000 'Millennium bug'. Strategies
to reduce the risk that cyber attack poses, at both individual and
national level, are described and compared with the actions being
taken by a number of Western governments.

Malware poses one of the major threats to all currently operated
computer systems. The scale of the problem becomes obvious by
looking at the global economic loss caused by different kinds of
malware, which is estimated to be more than US$ 10 billion every
year. Botnets, a special kind of malware, are used to reap economic
gains by criminals as well as for politically motivated activities.
In contrast to other kinds of malware, botnets utilize a hidden
communication channel to receive commands from their operator and
communicate their current status. The ability to execute almost
arbitrary commands on the infected machines makes botnets a
general-purpose tool to perform malicious cyber-activities. Botnets
provides a comprehensive analysis of the topic, and comprises both
technical and non-technical sections written by leading
cybersecurity experts. The non-technical section addresses how
botnet infrastructure could be exploited for national security and
cybercrime purposes. It approaches the subject as a public policy
issue and analyzes the phenomenon of botnets from national
security, law enforcement and regulatory policy perspectives, and
makes recommendations for policy-makers on different public
policies, highlighting the need for international response
mechanisms. The technical section provides insight into current
botnet techniques and discusses state-of-the-art countermeasures to
combat the botnet threat in detail. It includes new detection
methods as well as different approaches to actively compromise
running botnets.
