The Client – an overview
As one of India’s major international airports, it serves as a primary global gateway, facilitating cross-border travel, trade, and tourism. It had accelerated its digital transformation journey to improve operational efficiency and infrastructure resilience. With the expansion of its operational technology (OT) ecosystem that included baggage handling systems, access control, surveillance, and other industrial control systems, came the need for a robust cybersecurity framework to protect all mission-critical operations.
Background and Key Challenges
Managing an Operational Technology Security Operations Center (OT SOC) at an international airport in India presents several challenges, as does this airport. Specific issues for continuous monitoring and threat management included managing legacy systems, vulnerabilities, alert overload, stringent regulatory requirements, and emerging cyber-physical threats. This airport was operating within a Greenfield OT SOC environment, where cybersecurity controls for operational and industrial systems were still in the process of evolving. As OT and IT systems became increasingly interconnected, the airport faced several cybersecurity and operational risks.
◆ Converged IT and OT networks with limited segmentation, causing increased exposure to lateral cyber threats.
◆ Unsecured OT network zones and weak access control mechanisms.
◆ Presence of unauthorized software on OT‑connected systems.
◆ Use of workgroup‑based systems without centralized security enforcement.
◆ Limited awareness among staff regarding OT cybersecurity policies and operational security practices.
◆ Lack of structured OT cybersecurity training programs.
◆ Inadequately reviewed and documented OT network security policies.
◆ Increased operational risk from potential cyberattacks capable of manipulating industrial systems and algorithms.
◆ Safety and security concerns involving airport ground staff and critical operational systems, where certain attacks could potentially trigger physical damage or even life-threatening incidents, including blast scenarios.
To address these challenges, the organizations partnered with Inspira Enterprise to establish a secure and resilient OT Security Operations Center (OT SOC) environment.
◆ Enhance visibility across critical OT assets and industrial control systems.
◆ Conduct OT-safe vulnerability assessments, minimizing operational risk.
◆ Review and harden OT switches and firewall configurations
◆ Implement OT cybersecurity controls aligned with IEC 62443 standards.
◆ Segregation of IT and OT networks to minimize cyber risk exposure.
◆ Establish a centralized OT SOC for continuous monitoring and threat management.
◆ Design and validate OT architecture based on the Purdue Enterprise Reference Architecture
◆ Deploy layered security controls to prevent unauthorized access and lateral movement.
◆ Enhance operational resilience while ensuring uninterrupted airport operations.
◆ Build cybersecurity awareness and governance across OT teams and stakeholders.
◆ Ensure a reduction in the possibility of cyber incidents causing operational disruption or physical harm.
The Solution: Inspira Enterprise Approach
To address the identified cybersecurity challenges and strengthen the OT cyber resilience of the organization at the airport, Inspira Enterprise, a global leader in Cybersecurity, Data Analytics, and AI, developed and provided comprehensive OT cybersecurity services to ensure secure, reliable, and compliant airport operations. The team of experts at Inspira designed and implemented a comprehensive cybersecurity framework customized to the airport’s operational environment and critical infrastructure requirements. They implemented a multi-layered OT security strategy covering monitoring, governance, vulnerability management, endpoint protection, and compliance support while establishing uninterrupted operational continuity.
Key components of the deployment at the airport included:
● Continuous OT SOC monitoring: Continuous monitoring of mission- critical systems across the OT environment was implemented.
● Identification and analysis: Identification and analysis of OT security alerts and anomalies were done in real-time.
● Raising OT security incidents: After identifying the OT security incidents, the team assessed their severity and operational impact, followed by response actions, which were prioritized.
● Mitigation and remediation guidance: By leveraging advanced threat correlation capabilities, the OT SOC analyzed events and identified patterns across multiple OT systems and network layers.
● Incident closure and mitigation validation: Following remediation activities, validation checks were performed for effective threat mitigation and minimizing operational risks.
● Preparation and submission: The OT SOC team prepared and shared detailed daily OT security reports with relevant operational and management stakeholders, which enabled them to make informed decisions.
● Tracking: Continuous tracking mechanisms for alerts, incidents, vulnerabilities, and remediation progress were implemented, which led to better accountability and accelerated remediation efforts.
● Participation in ARB discussions: The OT security team participated in Architecture Review Board (ARB) discussions for new OT initiatives, automation projects, and infrastructure upgrades. The approach reduced security gaps and minimized the need for costly redesigns later in the project lifecycle.
● Review of proposed architectures: The team reviewed the proposed architectures from an OT security standpoint to ensure all new deployments aligned with operational security requirements.
● Recommendations for secure design: The OT security team provided recommendations based on internationally recognized OT cybersecurity frameworks, including IEC 62443 and industry best practices.
● Coordination: The team worked closely with internal stakeholders and OEM/vendors to finalize secure solutions, ensuring security controls were integrated without disrupting airport operations or performance requirements.
● OT Active Directory (OT‑AD): The team deployed OT Active Directory solutions to provide centralized visibility into connected OT devices and industrial systems across the airport environment, enhancing asset inventory accuracy and security monitoring across mission-critical infrastructure.
● Endpoint protection (OT‑compatible EDR/AV): OT-compatible endpoint protection solutions were implemented across eligible OT systems to strengthen protection against malware, ransomware, and unauthorized activities, improving endpoint security while maintaining system stability and operational continuity.
● Secure remote access: To address the risks associated with remote connectivity, the team implemented secure remote access mechanisms for OT systems and industrial environments, reducing the risk of unauthorized access while enabling secure operational support and maintenance activities.
● Centralized OT asset management: Centralized OT asset management and lifecycle tracking were established to improve operational efficiency and risk management.
● OT security documentation: Comprehensive OT security documentation, including network diagrams, asset inventories, and SOPs, was developed and maintained to support governance, operational consistency, and audit readiness.
● OT security audits: The Inspira team also helped in strengthening OT compliance posture and audit preparedness, which enhanced the airport’s readiness for cybersecurity assessments and regulatory reviews.
● Ensuring adherence: The team aligned the airport’s OT cybersecurity practices with applicable globally recognized standards and industry frameworks, strengthening its cybersecurity maturity and governance framework.
● Gap analysis and corrective action: The team conducted OT security gap analysis and implemented corrective measures for audit observations, which strengthened the airport’s OT security posture, ensuring long-term compliance and operational resilience.
