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 volume identifies the security problems facing internet communication protocols along with the risks associated with internet connections. It also includes an investigative case study regarding the vulnerabilities that impair IPSec and proposes a SIPSec Model.
