| Summary: | Traces of the packets transmitted across a network can be beneficial for troubleshooting network problems, aid as crucial data source for monitoring and management of computer network. Still, they often contain sensitive information such as user logon credentials, which website users have visited, files transfer details, locations of user emails, banking details, names or addresses that belong to someone. There are numerous sanitization or anonymization tools available to hide sensitive information but they tend to be focused on to sanitizing large volumes of network traces to feed repositories of traces that researchers can use to study network traffic flows rather than sanitizing small number of packet traces or focusing on traffic trace for a single user. Moreover, these existing tools are concentrating on sanitizing on lower layer protocols which is up to the TCP layer and eliminate application layer headers. This research will conduct an experimental study on seeking better techniques on how to sanitize the sensitive information in the application layer of TCP/IP Stack at (Level 7 of The OSI Model). It aims to contribute towards an improvement of packet traces sanitization techniques. As a result, a new application-level specific technique for packet sanitization is developed. The proposed technique will be compared with existing techniques in packet sanitization such as Tracewrangler, Anootool and tcpanon during the evaluation phase. The developed technique can be served as a tool to assist network troubleshooting task or for learning purposes in small scale organization. |
