E-mail system is one of the critical infrastructures of any organization. It is necessary to ensure that the mail servers in use should be secured in such a way that no security properties like confidentiality, integrity, and authenticity are compromised. To achieve these security properties we have setup a secure e-mail server testbed that provides security against malware and spam, and guaranties secure e-mail delivery. This paper proposes a secure methodology for filtering spam and malware in the e-mail system, comprising standard layers of protocols and policies. An experimental testbed is established to evaluate the effectiveness of our methodology and was tested with spam and malware e-mails. Our results showed an accuracy of 95 percent, against a typical configuration of an e-mail system.

The Internet is a collection of many independent networks. Interconnection of these networks is achieved through the implementation, on each network, of a common service provided by the Internet Protocol (IP). This service allows systems attached to the Internet (called “hosts”) to direct packets of data (called “IP datagrams”) at each other—the service provides confirmation neither of success nor failure. Applications that require guarantees about delivery must employ a suitable “transport protocol” between the hosts on which they run. This chapter describes the IP service and gives a detailed account of its implementation, including the use of IP addresses and the operation of “routers” that relay IP datagrams between networks. It covers multicast transmission, mobility, security, and a new version of IP, IPv6. It describes the “end‐to‐end” protocols used on the Internet, the transport and application protocols. Finally, the chapter describes recent additions to the Internet architecture intended to support real‐time interactive applications.
