We disagree. Patches changes code which has already been operationally and functionally tested. This requires additional testing for each update and patch and that takes time, money, and other resources away from other things. Therefore no wonder when operations scale upward, the cost of security goes exponential. It's because of all the waste.Please share the research you have that backs up this statement. I would be very interested in knowing the details that that provide the foundation for this argument. I'm particularly interested in the cost points and identification of the exponential cost of security from patching and the money saved by not patching in your environment. I presume that you have empirical evidence of the vast savings based on concurrent operational models in an enterprise environment, so I'm curious as to how many thousands of servers you are operationally responsible for, because that information is not only critical, but required for this model to be considered. IOW, if you could share the analysis you presented to management that they bought off on, that would extremely helpful.
Maybe you misunderstood this? If you need empirical evidence that patches change code then please do a diff yourself between two apps, one patched and one not. Here I was writing of the cost of functional testing and remediation of the operational security which scales exponentially as the operations scale. One doesn't need a server farm to prove as more servers are introduced into an operation that the number of connections between them grows. 2 servers each with 1 connection has 2. Add 2 more servers and now you have 4 servers but 8 connections to verify. And it goes on like that. If you don't do any testing and don't care then you don't have that work or money to lose with patching. But I said that already. -pete. -- Pete Herzog - Managing Director - pete () isecom org ISECOM - Institute for Security and Open Methodologies www.isecom.org - www.osstmm.org www.hackerhighschool.org - www.badpeopleproject.org _______________________________________________ Full-Disclosure - We believe in it.
