Preventing Unauthorized Access to My Industrial Network

If one of your employees or suppliers uses valid credentials to gain unauthorized access to your industrial network, would you know about it? How long would it take?

What if they give their credentials to a remote threat actor who then inserts malware onto your control network and deletes log files to disguise their activity? What if a maintenance worker without permission to connect to your industrial network does so anyway – and deliberately or accidentally introduces malware?

Cybersecurity threats come in multiple forms – external and internal, intentional and accidental. Whatever the root case, detection and early warning are critical to containing risk and potential damage.

THE SOLUTION

A Comprehensive Approach to Detecting Cyber Risks and Threats

Nozomi Networks takes a multi-pronged approach to identifying suspicious, unauthorized activity.

Guardian uses behavior-based anomaly detection and multiple types of signature and rules-based detection to identify unauthorized activity such as:

  • remote access
  • log file deletions
  • configuration changes
  • downloads
  • controller logic changes
  • edits to PLC projects and more
Guardian correlates detection results with operational context to generate specific, actionable alerts about potential credential theft. For example, it checks baselines for network peculiarities such as VPN access and IP ranges assigned to vendors. If a vendor activity falls outside those ranges, Guardian alerts your security and operations staff.

The Asset Intelligence and Threat Intelligence subscriptions continuously update Guardian™ appliances so you can quickly detect and respond to cyber threats and anomalies.  

Easily identify suspicious, unauthorized behavior such as remote access, configuration changes, log file deletions, controller logic changes and more.

Advanced Cyber Threat & Risk Detection

Guardian delivers advanced cyber risk identification capabilities that help you uncover operational threats in real-time.
