Operational Technology Security trends - stay safe by being ahead

// news

As technology evolves, operational technology security challenges become increasingly complex. In the past, cyberattacks on OT systems were often straightforward, but in recent years, cybercriminals have become more sophisticated.

One of OT security’s biggest challenges is the rapidly changing technology landscape. There are now more connected devices and systems than ever, creating a larger attack surface for cybercriminals to target. These devices and systems can include everything from sensors and controllers to SCADA (Supervisory Control and Data Acquisition) systems, all critical to industrial processes. Another challenge facing OT security is the increasing sophistication of attacks. Attackers constantly develop creative techniques and tools to exploit OT vulnerabilities. They use social engineering tactics such as phishing to trick users into giving up their credentials or opening a malicious attachment.

Ransomware attacks are also becoming increasingly common, where attackers take control of an OT system and demand a ransom to release control of the system. These attacks can have severe consequences, from disrupting production processes to removing hazardous materials. A lack of standardization in OT security is also a significant challenge. While the IEC 62443 standard has been developed as a framework to secure industrial control systems, including OT systems, not all organizations, have implemented it. This lack of standardization makes it difficult for regulators to enforce security requirements and hold companies accountable for security breaches. Legacy systems are another significant challenge for OT security. Many OT systems are based on legacy technology from vendors or manufacturers that no longer support them. This makes it difficult to update these systems with the latest security patches and upgrades, leaving them vulnerable to attacks.

 

 

Human error still contributes to security breaches. Even with the most effective training and policies, employees can still make mistakes that compromise security. This can be due to a lack of awareness, insufficient training, or carelessness. Organizations must stay current on the latest security threats and trends to address these challenges. In addition, they must implement best practices for securing their OT systems. Implementing the IEC 62443 standard is an excellent first step toward this goal. The standard provides a comprehensive approach to cybersecurity for industrial automation and control systems. It includes guidelines and best practices for secure system design, development, installation, and operation. However, organizations must also tailor their security strategies to specific OT environments and risks. This involves identifying and prioritizing critical systems and assets for protection and implementing security controls accordingly. It is also imperative to conduct regular risk assessments to identify and address upcoming threats as they emerge.
