Network Theory & Design

The existing diversity on the internet has provided for the growth of a different business. Clients have to provide personal information when purchasing products online to verify who they are. To protect such information particular measures exist. HTTPS was introduced as a secured communication channel to ensure reliability. The article intended to address the issues relating to HTTPS drawbacks and proposed three distinct techniques to improve the above. There are three techniques used to protect a user’s confidential information. Using Static ARP is the first technique. Regarding the Man in the Middle technique, ARP spoof is recommended to deceive both the gateway router and the victim. The administrator configures the switch only, and he/she does not have to configure the client unless they are new to the network. However, some models of the switch lack the “Port Secure” feature. The use of ARP Watch is the second technique. This software is used to monitor the similarity between the MAC Address and IP Address. The process of monitoring similarities is achieved using an ARP table. Once it is setup on the victim’s side, it initiates an alert to warn the administrator that ARP Spoof is running. An advantage of ARP watch is that a hacker can be traced using the signal and this information is saved as evidence. The disadvantage is that there exists incompatibility support between the software and the device. The use of Anti-Sniff is the final technique. This application detects a machine that is currently running in promiscuous mode. It can be installed on any machine provided it is on the same network. Flexibility is an advantage of using this technique. However, monitoring and scanning must be carried out at all time. In conclusion., the paper proposes that the above three methods should be implemented to give the best performance while guaranteeing safety.
