Is there any way to secure network traffic between any two applications with SSL even both applications don't support SSL mode?


(Host X (Application A) ) --------unsecured connection----- (Host Y (Application B) )

(Host X (App. C (App. A)) ) -----secured connection------- (Host Y (App. C (App. B)) )

try stunnel.

and if it does not have to be ssl, try a ssh tunnel.

Thanks! I will definitely try stunnel. I'm interested in securing JDBC but do not want to end up paying lots of $$$ for built-in SSL. – user31775 Jan 19 '10 at 20:42

Depends on the application but almost certainly yes.

For instance you could just setup an IPSec tunnel, or use IPv6 or lots of other ways - talk to us more about your application please.

Thanks, the application is Oracle Database 10gR2. I know Oracle offers Oracle Advanced Security, but I prefer not to pay an additional $11k per processor just for JDBC over SSL. I will research IPSec tunnel, but I'm not sure what you mean by IPv6. Thanks again. – user31775 Jan 19 '10 at 20:44
