In OT Environments, Security Must Not Be an Afterthought

The dream of a cloud-enabled operational technology, or OT, environment is becoming a reality thanks to daily innovations in technology, which have the potential of turning legacy control systems into integrated IIoT instances. These changes are happening at a fast pace, and are often extraordinary in scale. Large scale ICS SCADA systems, such as those found in oil and gas are evolving; however, one thing remains constant: poor security.

 

Why Security Is a Challenge

As IT security professionals know, security must adapt to an ever-changing threat landscape. A fluid model does not play well with most current ICS and SCADA systems. These systems depend on availability first, making the application of security measures challenging to implement and even harder to maintain. For OT operators, security must support a model that allows technicians to connect devices first to configure and fine-tune them, and then later lock them down. There must be enough security in place to protect both the business and the process control environment from attacks, but with just enough protection that it neither overcomplicates the automation groups workflows nor stops, blocks or disrupts production.

Purpose-built and expensive to update or replace, these systems and networks do not conform to the equipment lifecycle of an IT network. The majority of oil and gas field networks and remote process control networks are archaic, but also happen to be the systems we take for granted on a daily basis. Attackers know that, when and if these systems fail, they can affect our daily lives.

 

What’s Next?

It is time we change our beliefs on what a secure network looks like and how it should work? As organizations adopt cloud-based infrastructures and other IIoT technologies, security does not have to be an afterthought. Our Security Operating Platform secures control system networks in several ways, including automatically preventing new and unknown threats, providing virtual network segmentation and offering role-based network access.

Unit 42 Report - Ransomware: Unlocking the Lucrative Criminal Business Model
Ransomware, specifically cryptographic ransomware, has quickly become one of the greatest cyber threats facing organizations around the world. This criminal business model has proven to be highly effective in generating revenue for cyber criminals in addition to causing significant operational impact to affected organizations. It is largely victim agnostic, spanning across the globe and affecting all major industry verticals. Small organizations, large enterprises, individual home users – everyone is a potential target. Ransomware has existed in various forms for decades, but in the last several years criminals have perfected the key components of these attacks. This has led to an explosion of new malware families and has drawn new actors into participating in these lucrative schemes.
