MetaDefender Netwall Unidirectional Security Gateway

A leading thermal power plant in Southeast Asia serves as a cornerstone of the region’s energy infrastructure, contributing 1,200 MW to the national grid and supporting economic development. Operated by a major electricity provider, the plant utilizes advanced supercritical coal technology to generate power efficiently while minimizing environmental impacts. 

However, facilities like this face an ever-growing cyber threat landscape. In Southeast Asia, reports indicate a 300% increase in cyberattacks targeting critical infrastructure between 2019 and 2023, with energy facilities being among the most targeted. Globally, over 56% of power plants have experienced cyber incidents in the last three years, highlighting the pressing need for robust cybersecurity measures to guard against ransomware, malware, and zero-day threats.

Protecting Critical Infrastructure from Emerging Threats 

In recent years, this power company has encountered complex security threats typical of critical national infrastructures, including external attacks and internal risks that impact its IT, OT, and SCADA networks. The plant's representatives shared, "As a national critical infrastructure, we face a range of increasingly complex cybersecurity challenges." These include:

  • External Threats such as malware, ransomware, phishing, DDoS attacks, and zero-day exploits. 
  • Internal Risks from potential human error or lack of cybersecurity awareness, with some employees at risk of inadvertently downloading malware or exposing sensitive information. 
  • Cross-Domain Security Concerns from the need to secure segmented IT and OT networks to prevent IT-based attacks from reaching operational systems. 
  • Regulatory Pressures to comply with strict cybersecurity mandates for energy providers. 

Previous incidents—such as malware infiltrating the IT network and attempted unauthorized access to the SCADA system—highlighted the need for advanced cross-domain security, prompting the adoption of OPSWAT’s MetaDefender NetWall Unidirectional Security Gateway.
