of the operational technology security equation
(and why it’s risky to focus on only one)
One could argue that industrial cybersecurity is suffering from the operational equivalent of dissociative identity disorder.
The first persona is on-site operational personnel with an engineering background responsible for security maintenance or system hygiene. The second persona is at the corporate level, in the CISO team or a 3rd party managed security services provider (MSSP) and comprises security analyst teams with a digital security background usually backed by third-party security architects.
Persona 1 is proactive and hands-on, whereas persona 2 is inherently reactive.
Today’s risk-intensive operational technology (OT) security demands a secure atmosphere with zero downtime. In such a scenario, personas 1 and 2 must work together closely to prevent and mitigate risk across the digital environments by adopting a proactive approach.
In today’s volatile cybersecurity climate, the only way to truly mitigate damage is to prevent it. The question is: how can personas 1 and 2 work together effectively to achieve this goal?
The left side shows proactive controls and is referred to as operational security (OpSec).
OpSec focuses on proactively mitigating gaps before they become breaches. OpSec incorporates controls that include governance and policy implementation, gap and exposure identification and network architecture, to name a few.
The right side of the diagram shows reactive controls and is referred to as security operations (or SecOps).
SecOps efforts revolve around the security operations center (SOC), which focuses on day-to-day missions like monitoring systems, logging, anomaly detection, threat hunting and incident response.
Today, most OT security solutions in the market focus on the reactive SecOps paradigm – the right side of the diagram. These solutions detect and respond to security incidents after they happen.
Similar to contemporaneous trends in digital security, the OT solution requires adding automation and orchestration capabilities and integrating them into risk-based management routines, while enabling tighter collaboration with off-site cybersecurity teams.
Here is what companies can do to ensure this happens:
Move beyond the reactive-only vulnerability and anomaly detection approach by embracing proactive risk avoidance solutions and services
Accelerate OT/IT convergence by utilizing multi-function platforms that understand, control and orchestrate the diverse OT/IT/IIoT systems in the organization
Make sure that your security stack can dynamically adapt to changing threat vectors and risks
These steps will allow personas 1 and 2 to coexist, and effectively meet their shared goal of cost effectively creating a secure and productive production floor.
