HYBRID SECURITY ARCHITECTURE FOR DATA COMMUNICATIONS (SADC)

Abstract

Communication networks and Internet had a tremendous growth in the recent past years. Today most of the government sectors, financial institutions, corporations, military and others exchange huge amount of confidential information by using the Internet Application Layer security is a growing area of concern for developers, designers, quality assurance specialist and programmers. Application security is the prevention of flaws and vulnerability that occur in the design, development, and deployment of applications that run on application layer of TCP/IP Protocol Suite. Although IPv6 both simplifies and improves IPv4, it poses several significant security challenges. First, even though IPSec support is mandatory in IPv6, its use is not. Not using IPSec exposes a network to old IP-related attacks as well as attacks related to IPv6-specific features. A working IPSec infrastructure is also difficult to deploy and manage, further reducing IPSec’s use. Some problems that affect IPv4 networks such as application-layer attacks, rogue devices and packet flooding can also affect IPv6 networks. Finally, several other new, unanticipated security problems will arise as the hacking community starts actively targeting IPv6 networks. This paper proposes new security architecture for data communication.
