Motivation We plan to device a heterogeneous service that would monitor the resolution of the user’s requests across different browsers. HTTP links accessed by the user would be checked for potential DNS poisoning against a DNS lookup performed by a secured server (one of the those kinds hosted by any anti-virus service). The server enumerates the list of the IP addresses which can then be compared with the local look-up for making a secured redirection to the user.

What is DNS? Domain Name System Integral part of the Internet, without which it will collapse. Used to convert a domain name into an IP address. OS asks the Resolving Name Server for the location of domain name. If RNS has no information, it contacts the Root Name Server for the location.

Current Progress We have written a java code that can capture DNS requests made by a user. (Client) We have written another code that converts the given domain name into an IP address. (Server) Client code is also capable of performing above mentioned Server functionality.

Next Steps We have to establish a secure connection between the Client and Server. We have to implement an interface which pops out an error message in case the client request and server response do not match.
