Network Segmentation to Enhance OT Cybersecurity

Industrial Cybersecurity, Network Architecture

Network segmentation is one of the most effective strategies to enhance OT security.

Select Dynamic field

A number of studies have found that untrained employees are the biggest threat to an organization’s network security. A study[1] by ESI ThoughtLab found that 87% of executives are aware of this fact. Consequently, companies of all industries and sizes are now putting more focus on preventing (or minimizing) attacks by investing in training for employees using Operational Technology (OT) systems including Industrial Control Systems.

Common Pitfalls

  • Operators accidentally click on a link in a phishing email from an operator station
  • Poor credential management: Allowing unrestricted access to system areas or functions that are not needed for an operator’s job role
  • Incident preparedness: No incident response program. What if something did happen? Is there a well-prepared plan in place?
  • User’s credentials are not removed from system when leaving the company.

Mitigation through Cybersecurity

Even trained employees are human. The good news is many weak links can be prevented by improving the security of your ICS network.

Champion’s Certified Cybersecurity Experts are trained in the latest ISA/IEC 62443 and NIST standards for Industrial Cybersecurity. This means you benefit from the most current, comprehensive safeguards for your operations.
