Suppose Abu goes to the coffee shop nearby with free WiFi facility. He finishes his works by web-surfing and tweeting. He knows that the WiFi network that he used to send all packets is unencrypted, and he saw a person ' A ' (attacker) seated at the table next to him, using a laptop connected to the same WiFi network. For Abu's web connections, consider the basic security properties of confidentiality, integrity, and availability. Analyze based on the following three scenarios: (1) DNSSEC- only means that for a given website, his laptop looks up all of the domain names for his web session using DNSSEC (including NSEC3); however, the actual web traffic uses HTTP. (2) HTTPS - only means that for a given website, his laptop looks up all of the domain names for the web session using ordinary DNS; however, the actual web traffic uses HTTPS. (3) DNSSEC and HTTPS - means that both his domain name lookups use DNSSEC and the actual web traffic uses HTTPS. In each of the following statements, state each of the previous statements (1) to (3) YES, if a person ' A ' is using only his laptop (no additional equipment) that can weaken the ability of Abu's connections, or NO if no attack from him. At the end of each section, supply a brief explanation for your answers for Abu's network connection. (i) Confidentiality of web connection content. [3 marks] (ii) Confidentiality of keeping private what websites that he communicates with. [2 marks] (iii) The integrity of the web connections. (iv) Availability of the web connections.
