PLC Security Creating and implementing an


effective strategy to remain secure can help to avoid issues, downtime and setbacks. Understanding the different types of PLCs is necessary to secure them correctly and it is important to have strategies regard- ing both cybersecurity and physical security.


Cybersecurity measures include


incident response planning, drafting and reviewing policies and proce- dures, preparations for a breach, insurance review, Payment Credit Industry (PCI) compliance protocols, and vendor contract management protocols.


Although physical security dif-


fers from PLC cybersecurity, it is still important and should be prioritized when an individual or a company is undergoing breach simulations, training and exercises. Physical security includes correcting default passwords, ensuring only certified individuals are in the control sys- tem’s environment and limiting access to thumb drives. In order to create and imple-


ment training and procedures for staff, first understand how issues with security occur. Not all cyberse- curity attacks come from external hackers or scammers. In fact, experts believe that only an estimated 20 percent of all cybersecurity attacks are intentional and intended to be malicious. Many cybersecurity issues come


from software bugs, device problems and malware infections. As many in the automation space know, PLC cybersecurity hardly existed a decade ago. These days, PLCs are connected to business systems through regular networks and are not separated from the networks that automation equip- ment may be on. It is becoming more and more common to see TCP/IP net- work from a business system stand- point. By connecting through TCP/IP, data exchange is more reliable and more scalable business decisions can be made.


Security Factors Although they may not actually


connect to the internet, control sys- tems are unsafe. Contrary to popular belief, even a modem connection can be hacked. Wireless networks, laptop computers and trusted vendor con- nections could be other weak links that companies overlook. The majority of IT departments are not familiar with factory automa-


The majority of IT departments are not familiar with factory automation equipment, including PCB manufactur- ing equipment, robotics


and PLCs. IT workers who lack experience with this equipment and have little knowledge of industrial standards and scalable processes indicate that they should not be in charge of the company’s PLC security.

tion equipment, including PCB man- ufacturing equipment, robotics and PLCs. IT workers who lack experi- ence with this equipment and have little knowledge of industrial stan- dards and scalable processes indicate that they should not be in charge for the company’s PLC security. Nobody needs an annoyed employee making inappropriate changes to a PLC’s communications highway. Hackers do not necessarily need


to understand the PLC or SCADA to block PC-to-PLC communication. They absolutely do not need to understand a PLC or SCADA system to cause operational or programming issues. Often, control systems,


including ones that many PLCs inte- grate with, use Microsoft Windows, which is frequently exploited by hackers. Some PLCs crash simply by


pinging an IP address, like what happened at the Brown’s Ferry nuclear plant in 2006, located in upstate Alabama. Since the incident, the plant has undergone numerous security, operational and manage- ment improvements. When a security breach occurs,


regardless of the specifics, under- standing that time is of the essence will help to smooth over most inci- dents. Trusting personnel with access to a control systems environ-

ment and thumb drive is crucial. While malicious events are fair-


ly rare for most factories, further interconnection of production proces - ses is growing more risky. While the cost of security, including employee training, job and process tracking, and building and IT security is high, the cost of one large-scale breach could be disastrous to a firm’s prod- ucts and reputation. Security is an easy cost to justify. Contact: MRO Electric and
