Transcript

So, when thinking about operational security, what are the things that we need most? Well, we need performance, we need reliability, we need availability. And we need to be sure that the program will not only do everything we want it do in the way of functionality, but that it doesn't do things we don't want it to do or have security problems that threaten the software and the data that it processes.

Now overall, we need to have a process that covers these three elements. Prevention, which includes things like access control, firewalls and encryption . Detection, which includes ways and means for us to know what is going on whether it's appropriate or not. And that would include things like audit logs, IDS IPS types of systems and deception technology. Followed by reaction, and this would include all the different ways and methods that we would use to respond to anything we find that is untoured, unknown or outright hostile. This would include our incident response team, the performance of forensics, the processes of restoration, and then finally the resumption of our business.

Now, we always need to remind ourselves that what we're looking for is not perfect security. We're looking for it to be commensurate protection. That is, it needs to be quite literally good enough to be able to protect the system and its data to a level that is appropriate to the value of the assets it is processing.
