As power plants become increasingly digitized, they face growing risks from cyber threats targeting critical infrastructure. Ensuring cybersecurity in power plants is essential to maintaining energy supply, preventing blackouts, and avoiding national security breaches. Modern security measures include real-time threat monitoring, secure network segmentation, intrusion detection systems, and robust access controls. Additionally, regular audits and staff training help identify vulnerabilities before they are exploited. Many facilities also follow global standards like NIST and ISO to strengthen their cybersecurity frameworks. With rising concerns about nation-state attacks, investing in cyber defense for power plants has become a top priority worldwide.
