We have a legacy application built on RMI Client Server Communication.
I know the rmi network traffic can be intercepted and can be modified and hacker can extract the confidential information.
I wanted to know if there is a way I can secure the communication between client and server with minimal changes to application or otherwise if there is any efficient way to tackle this issue.
Any help is highly appreciated.
RMI can be secured, have a look for example at this Oracle's documentation page. Because you're dealing with a legacy application, you may evaluate to secure socket connections by creating encrypted VPNs between peers, so acting at OS level.
