RESUMO

The range of TCP/IP protocols and applications is probably as wide as is strong the need for security mechanisms in this architecture. The scope of the security aspects goes from the inherent security of operating systems, through firewalls, cryptography and secure channels, up to specific applications. As a general rule, little literature deals thoroughly with this issue, especially with regards to cryptography and its relation to secure TCP/IP protocols. As such, this work focuses on enumerating the intrinsic problems of the TCP/IP architecture, dealing with the security issues with special emphasis in firewall technology and in cryptographic algorithms, as well as in their relation with regards to building secure communication channels. As an application for this study, directions for the development of critical security applications in an HTML/HTTPS environment were obtained, which were the basis for the implementation of the Internet banking system for BankBoston in Brazil
