Given the present environment at SLAC with regards to work planning and control, it is somewhat surprising that this activity would proceed without a wider broadcast and approval process. Our control systems are designed and built to operate nominally within a network environment consisting of known types of traffic. Testing during installation and commissioning confirms to the extent possible that our systems are robust in the ways we designed them to be. The introduction of cybersecurity testing, which is an aspect we don't strictly consider in our designs, is risky. That risk is compounded due to lack of communication. These are lessons we must learn from. On the positive side, we now have a stronger relationship with SLAC Cybersecurity than we have had before. Also, while system security was a growing concern for the CSWG, these assessments have increased our attention and perhaps motivated us to more seriously consider the topic.
