Fraud poses a significant threat to the Internet. 1.5% of all online
advertisements attempt to spread malware. This lowers the willingness to
view or handle advertisements, which will severely affect the structure
of the web and its viability. It may also destabilize online commerce.
In addition, the Internet is increasingly becoming a weapon for
political targets by malicious organizations and governments. This book
will examine these and related topics, such as smart phone based web
security. This book describes the basic threats to the Internet (loss of
trust, loss of advertising revenue, loss of security) and how they are
related. It also discusses the primary countermeasures and how to
implement them.
