you’re an app developer with a solid foundation in Objective-C, this book is an absolute must—chances are very high that your company’s iOS applications are vulnerable to attack. That’s because malicious attackers now use an arsenal of tools to reverse-engineer, trace, and manipulate applications in ways that most programmers aren’t aware of.
If a company’sWeb site is used to collect, compile, or process customer data, that company has an added point of vulnerability. The increased
vulnerability in this situation arises from the potential of a hacker breaking into the Web site and stealing data such as names, address,
account information, or credit card numbers. In addition, if the Web site is integrated with back-end applications or connected to other
systems in the enterprise, there is a greater possibility that hackers and information thieves can access more sensitive information that
otherwise may be kept private.
WiMAX operates on the same general principles as Wi-Fi — it sends data from
one computer to another via radio signals. A computer (either a desktop or a laptop)
equipped with WiMAX would receive data from the WiMAX transmitting station,
probably using encrypted data keys to prevent unauthorized users from stealing
The new overwatch security pillar acts as an infection detection, containment, and
remediation engine that is automatically triggered when a threat has bypassed
detection by the existing "in-line" infrastructure and has infiltrated the enterprise
network. The overwatch security layer uses data from a real-time reputation and
behavioral correlation database to detect active data-stealing malware and other
With the Android platform fast becoming a target of malicious hackers, application security is crucial. This concise book provides the knowledge you need to design and implement robust, rugged, and secure apps for any Android device. You’ll learn how to identify and manage the risks inherent in your design, and work to minimize a hacker’s opportunity to compromise your app and steal user data.
Impersonation is closely related to unauthorized access but is signiﬁcant enough to be
discussed separately. Impersonation is the ability to present credentials as if you are
something or someone you are not. These attacks can take several forms: stealing a private
key or recording an authorization sequence to replay at a later time. These attacks are
commonly referred to as man-in-the-middle attacks, where an intruder is able to intercept
trafﬁc and can as a result hijack an existing session, alter the transmitted data, or inject
bogus trafﬁc into the network.
Viruses, worms, Trojans, and bots are all part of a class of software called malware. Malware or malicious code (malcode) is short for malicious software. It is code or software that is specifically designed to damage, disrupt, steal, or in general inflict some other “bad” or illegitimate action on data, hosts, or networks.
Attackers break into the web application by thinking like a programmer: identifying how the
application is intended to work and determining shortcuts used to build the application. The
hacker then attempts to interact with the application and its surrounding infrastructure in malicious
ways simply by using the web browser or any of a large number of automatic hacker tools, such
as CGI scanners and HTTP proxys.
These days, as Internet dangers and risks increase exponentially, administrators of corporate
networks are obliged to pay special attention to user workstation protection. Corporate servers
can be very well protected, yet their client workstations may have backdoors for outside
intrusions, which can be used to steal internal data or introduce confusion.
To reduce the amount of network traffic and to control Internet usage by staff, administrators are
filtering web site content and blocking net advertisements.
