Finally, I have managed to integrate Nessus with enVision.
I have installed Nessus 3.0.6 with client 1.0.2 on Fedora Core 6. Now the Nessus Scan reports are getting parsed in enVision. I can see some IP address under the Assets Tab. There are vulnerability information for the corresponding IP address under this list.
It seem like a typical configuration but its easy if someone knows the basic commands of Linux.
Now the problem is, that I am not able to understand what to do with this extra information that I have now at my hand in enVision.
VAM is confusing in enVision and the online help does not actually helps a lot. I have raised a ticket with RSA and they have sent me some executables, but I was not able to test it.
Will keep you updated if I am able to get some more info in this.
till then take care.
