Valid node checking as a simple free firewall for the database

June 5th, 2007 by Pete

I was looking for a good reference for valid node checking last week to explain to someone who emailed me how it works and why its a great free Oracle firewall at the TNS level. I remembered I had seen a good paper by Arup Nanda some time ago and went for a look for it. The paper is called "Building a Simple Firewall Using Oracle Net" and is very well written as we have come to expect from Arup and is worth reading again hence I thought i would mention it here.
