# Topic and Description
|
||
Modern control systems are integrating more and more digital technologies. These technologies can be more efficient, and easier to update and maintain than an analog counterpart. With this flexibility, however, digital control systems are more vulnerable than analog control systems as control dynamics can be augmented through cyberattacks. I would like to dig in to how the nuclear industry will face regulating digital control systems and ensure robustness of critical NPP safety systems from cyberattacks.

|
||
## Introduction
|
||
## Digital vs. Analog Control Systems
|
||
The fundamental reason cybersecurity is a concern for nuclear power is the introduction of digital control
|
||
### How is control done now?
|
||
- Most safety systems (and other controls) are analog
|
||
- There are actual wires or air lines running to everything
|
||
- Bone simple to understand
|
||
- Difficult to maintain and adjust. Have to manually shim devices in electrical circuits or pressure systems for example.
|
||
- Security is a matter of restricting access. Humans have been doing physical defense for thousands of years. We're good at that.
|
||
### What is the future of control?
|
||
- Digital controllers (computers)
|
||
- Can be more efficient, more involved control solutions
|
||
- Can easily update
