Ensuring PLC Cybersecurity: A Quick Guide

It’s no secret that the modern corporate world is exposed to cyber threats every day. With technology adapted into several key parts of company operations, all criminals need to do is hack these systems to gain access to vital data. Even programmable logic controllers (PLCs) can be susceptible to these attacks. As such, it’s crucial that you take steps to protect these devices. This quick guide to ensuring PLC cybersecurity will help you get on the right track.

The Rise of Modern Cyber Threats

Modern cyber threats are becoming more sophisticated as hackers use more advanced techniques to infiltrate networks and exploit system vulnerabilities. This is particularly concerning for companies in the manufacturing sector, as cyberattacks can bring operations to a grinding halt and lead to costly data leaks. PLCs, in particular, are vulnerable to attacks due to their connectivity with equipment and use of outdated software. However, with the right security measures in place, you can protect your facilities and avoid any detrimental consequences.

Noteworthy PLC Security Risks

There are several specific security risks to look out for when it comes to your PLC devices. One of the most significant is certain parties receiving unauthorized access, which can result in data tampering, equipment damage, and theft. Remote workers also pose a risk to security, as unprotected sign-ins to the corporate network could lead to compromised credentials, making it easier for unauthorized personnel to gain access to the PLC. Therefore, it’s imperative that you take the necessary measures to protect your facilities to avoid any unnecessary risks.

Ways To Protect Your Facilities

There are several ways you can protect your facilities and ensure the cybersecurity of your PLC. Start by segmenting your network to reduce vulnerabilities, thereby making it harder for hackers to gain access. Additionally, use firewalls to prevent unauthorized access and consider replacing outdated software with newer, more secure versions. You could also make sure your employees are aware of common cybersecurity threats and how to protect themselves and the organization.
