In order to know whether there is a cyber security issue, we need to be aware of potential factors that can pose security threats. We need to have a complete overview and predictability of our own cyber security. This includes an overview of the installed base, both regarding to hardware and software, hereunder IP-addresses and configuration, not to mention available revisions and versions of software/firmware we are currently running. If you don’t have a complete overview of your installation, chances are that the installation is at risk. Most often, we don’t realize that we have a cyber security issue until it is too late.
