Industrial Control Systems (ICS) are essential for managing and automating critical infrastructure in sectors such as energy, water, transportation, and manufacturing. As ICS environments increasingly integrate with broader networks and adopt advanced communication technologies, they face heightened vulnerabilities to cyber threats. Unlike conventional IT networks, ICS requires stringent security measures that accommodate real-time operational demands, safety standards, and legacy system constraints. This paper provides an overview of the unique security challenges facing ICS networks, such as limited processing power, stringent availability requirements, and lack of standardized protocols. Additionally, it reviews effective countermeasures, including intrusion detection systems, network segmentation, and advanced encryption techniques, to mitigate potential threats. Emphasis is placed on the need for a multi-layered defense strategy, policy frameworks, and ongoing monitoring to enhance ICS resilience. The findings underscore the importance of tailored security approaches to safeguard ICS infrastructure against evolving cyber threats, ensuring reliability and safety in critical operations.
