Distributed Denial of Service (DDoS) attack is one of the most disruptive attacks in computer networks. It utilizes legitimate requests from hundreds or thousands of computers to specific targets to occupy targets' bandwidth and deplete targets' resource. In this work, we have attempted to not only mitigate DDoS attacks but also identify the source of attacks even behind Network Address Translation (NAT). This is followed by remedial actions such as denying further access or informing them that they have participated in the attacks.
This report presents a new algorithm to prevent servers from DDoS attacks. This algorithm requires that network routers or gateways collaborate with each other in order to detect suspicious traffic. The algorithm initiates a peer-to-peer communication among network routers or gateways to increase the probability of detecting unwanted traffic. We derive mathematical proofs based on cryptographic concepts such as birthday attacks to estimate the rate of attacks generated and passed along the routers. This implementation is to prevent the attacker from sending spam traffic to the server which can lead to DDoS attacks. The effectiveness of our implementation is evidenced in our experimental results.

This book sheds light on a major crime that is under-the-radar. Individuals and groups (known as gangstalkers) are using radio frequency waves and electromagnetic energy to electronically target and harm people. Also known as electronic harassment, this cyber crime is increasing exponentially, and the perpetrators are literally getting away with murder. Harassed individuals, known as targeted individuals (TIs) die of heart attacks, collapse and die with no specific cause, commit suicide, are mis-diagnosed with rare cancers, or labeled as mentally ill. Targeted Individuals (TIs) in society are maligned and isolated. TIs are victimized twice by a society that is not aware of cyber attacks and would have trouble understanding digital murder.This book sheds light on cyber attacks and seeks to stop these crimes. It also provides relief methods for targeted individuals. It specifically asks lawyers, police, coroners, and medical professionals to learn about this crime, learn how to spot it, and help TIs. With public awareness, methods and laws to catch these cyber criminals must be enacted.

The issue of cyber-security has been wrongfully divided into many parts, each part addressed separately. The approach
to cyber-security needs to examine the function of all the issues working together as in the study of complex systems.
Discussion: There is currently no effective cyber-security paradigm. Crime, exploitation, and invasions of privacy are
increasing costing billions of dollars and have even started to bridge into the physical world with the destruction of
uranium enrichment centrifuges in Iran by the Stuxnet virus. There are a multitude of cyber security issues, but the most
important topics address how to define malicious actions in cyberspace, the inadequacy of the international community
to address these actions, and how active a role the private sector should play in the overall cyber-security effort. There is
no groundbreaking technology that will solve this problem despite much work by government agencies and corporate
entities. In fact, this effort has compounded the problem of cyber-security being examined in its parts when it should be
looked at as a whole. This is a distributed problem that needs a distributed answer, a systems solution that works as in
any well engineered system.
Conclusion: The ideal answers for the individual issues of defining cyber-attack, applicability of current international law,
and the proper role of the private sector does not produce the best answer for an adequate cyber-security paradigm as a
whole. A system of solutions that produces an answer that is greater than their parts needs to be pursued.

In this ebook we outline a set of practical and pragmatic cyber security considerations for organisations designing, developing and, testing Internet of Things (IoT) devices and solutions. The purpose is to provide practical advice for consideration as part of the product development life-cycle from concept to after market support.
While IoT products by their very nature encompass many forms of traditional embedded devices and supporting systems, we felt that distilling our knowledge and experience in the specific context of IoT would be useful. A lot of the concepts in this eBook could easily be applied to many other related areas of software and hardware product development.
