Introduction
This paper intends to discuss the processes and the security technologies while accessing
websites which uses HTTPS. The communication between the user and web server are likely to
be attacked and thus there is a need to analyze the technologies that are required to prevent
attackers from modifying communication. The central idea of this paper is to discuss
authentication, confidentiality and integrity and Anti-Replay in order to address the requirements
of the report. It would also provide the evidence of the practical part associated with specific
topics with the help of screenshots. It can be concluded that this paper would be effective in
addressing all the requirements.
Discussion
Authentication Process
Communication of Web Browser with the Right Server
The communication of web browser and web server is achieved with the web server with
the help of TCP/IP. The communication protocol in a hypertext transfer protocol secure (Https)
is encrypted with the help of a secured socket layer (SSL). The browser ensures that it is
communicating to a right server with the help of the certificate authorities. These certificate
authorities are pre-installed in the software of the websites [1]. For instance, the certificate
authorities of Global Sign and Go Daddy provides certificates, and they are considered as the
trusted by the web browsers. The fig 1 and fig 2 shows the secured and not secured connection
for better illustration.
