The open design of the internet has not only opened many new opportunities for communications, but it has also opened many new avenues for attackers against organizations network and computing resources. Information security has become a major concern in recent times, as more and more computers are being connected to the global internet. With so much data transferring over the public networks, the risk for sensitive information has increased exponentially, while the increase of internet hosts continually requires additional function support. Synchronizing Internet Protocol Security (SIPSec) focuses on the combination of theoretical investigation and practical implementation, which provides an in-depth understanding of the Internet Protocol Security (IPSec) framework. The standard internet protocol is completely unprotected, allowing hosts to inspect or modify data in transit. This book also identifies the security problems facing the internet communication protocols, the risks associated with internet connections, delimitations of the IPSec, and finally, a "Synchronisation of Internet Protocol Security (SIPSec)" model. Synchronizing Internet Protocol Security is designed for a professional audience composed of researchers and practitioners in industry. This book is also suitable for graduate-level students in computer science. .
