Cybersecurity for Operational Technology

Securing operational technology is a whole other level.

Imagine a house with a bolted front door and a state-of-the-art home security system.

It may seem secure, but the back window is wide open, curtains billowing in the wind.

Ignoring your cybersecurity strategy for operational technology is no different.

Top 6 OT Cybersecurity Vulnerabilities

01 | Over-reliance on air gap 

Typically, OT systems have been segregated from the company’s network IT by an air gap. Oftentimes air gaps are not regularly audited, scanned or veri ed to ensure lack of connectivity.


02 | Lack of training 

Many organizations have not put policies or procedures in place to help employees and vendors consistently utilize good security practices.


03 | Poor network segmentation 

Organizations often do not effectively utilize the concepts of zones and conduits. By limiting access and egress to specific zones, incidents can be better contained.


04 | Poor incident response 

Often, documented steps for responding to and containing an incident are limited or worse, non-existent.


05 | Poor passsword practices 

Strong corporate password protection policies are not always carried over
to the OT environment. Operators and administrators may have the same user names for various shifts.


03 | Absence of notification or detection

How does an organization know when something is wrong?


We Secure Your Operational Technology

Ignoring operational technology cybersecurity is like leaving the back window or door wide open.

Maybe you’ve set up a firewall, hired a CISO or even performed a vulnerability assessment with a large consulting group. Those action items or checked boxes are giving you a sense of security, a plan. But the problem is, it’s a false one.

All your planning has secured the information technology (IT) side, while at the same time your operational technology (OT) is left wide open and it’s a dangerous gap.

According to the HIS technology report, “Industrial IoT 2014,” less than half of Internet-connected devices are above the firewall. More than half are actually below it – in the operational technology (OT) underbelly.

The protection of critical assets has never been more top of mind as industrial attacks are on the rise. GrayMatter can help you create the OT cybersecurity plan that best fits your needs allowing your to make the best decisions for maintaining safety and availability across your operational technology environment.
