Cybersecurity Framework for Space Systems in India - An Analysis of the CERT-In Guidelines 2026
Introduction
In recent years, India has seen tremendous growth in its space industry. The satellite infrastructure of India now provides key services to a variety of sectors, including communication, navigation, broadcasting, disaster management and national security operations. Satellite communications globally will connect remote communities, aid in the delivery of Digital Governance and support India's strategic military capabilities. Given the expanding space ecosystem in India with the involvement of the public sector, private sector and research institutions, the security of satellite communications is becoming increasingly important.
At the same time, as satellite communication technologies become more pervasive, the risk of cyber threats targeting space systems increases. Cyberattacks against satellites, ground terminals or communication networks may critically impact, disrupt, damage, and/or destroy essential services, and expose sensitive information. To mitigate these risks, CERT-In (Computer Emergency Response Team), in collaboration with the SatCom Industry Association of India released a Cyber Security Framework and Guidelines for Space Platforms/Systems, including Satellite Communication, in 2026. This framework aims to establish and enhance cybersecurity measures throughout India's space ecosystem, while guiding how to better prepare for and respond to the growing volume of cyber threat activity targeting Space Systems.
Overview of the CERT-In Space Cybersecurity Framework
CERT-In introduced a dedicated cybersecurity framework for space systems in February 2026. Developed in collaboration with industry stakeholders, the framework provides guidelines to strengthen the security of satellite communication infrastructure across India. Although the guidelines are advisory in nature, they are designed to promote best practices and encourage organisations to adopt robust cybersecurity measures.
The framework targets a wide range of stakeholders involved in satellite communication operations. These include government agencies, satellite operators, ground station operators, equipment manufacturers, technology vendors, and emerging space startups. By outlining cybersecurity principles, technical controls, and governance mechanisms, the framework aims to create a coordinated approach to protecting space assets.
Another key objective of the guidelines is to foster collaboration between the public and private sectors. As India’s space industry expands and private participation increases, maintaining a secure and resilient ecosystem becomes essential. The framework, therefore, emphasises risk management, incident reporting, and continuous monitoring to strengthen the overall cybersecurity posture of the space sector.
Key Components of Satellite Communication Systems
Satellite communication systems are made up of multiple interconnected devices that can be used to deliver communication services. The cybersecurity framework groups these elements into three categories: the space segment, the ground segment, and the user segment.
The space segment is everything related to the satellite itself, including the satellite's onboard systems. This includes the satellite's communication payload, telemetry systems, antennas, power systems, and software that controls its operation. Because satellites operate in remote parts of space with very little opportunity for maintenance, securing these systems is critical in order to guard against unauthorized access to or control of these systems.
The ground segment comprises the terrestrial infrastructure responsible for controlling the satellite's operations. It consists of satellite mission control centres, ground stations, network gateways and data processing facilities. The ground stations send commands to the satellites and receive telemetry data from the satellites, which makes the ground station a very important physical interface point between the satellite asset located in outer space and a terrestrial network.
The user segment contains any device terminal being used by either an individual or an organisation that is accessing a satellite service. Examples of user devices are satellite phones, VSAT terminals, modems, and IoT devices connected to satellite networks. Since these devices connect directly to the communication networks, vulnerabilities in user equipment could also represent a significant threat to the cybersecurity of satellite communications.
Major Cyber Threats to Space Infrastructure
The space systems that support the delivery of satellite communications are being increasingly targeted with multiple types of cyber threats. A major category includes cyber-attacks on communication links between satellites and ground stations. Cyber criminals can attempt to jam the satellite’s communication link, intercept communication signals, or re-transmit previously sent communication signals in order to disrupt the operation of the affected satellites.
Attacks on the systems that control the satellite are serious threats to satellite operations. Cybercriminals and hostile actors can perform command injection attacks where commands are sent to a satellite, and the satellite responds through some undesired action. If cybercriminals are able to gain access to the telemetry or command channels, they can potentially disrupt the operation of the satellite or alter the telemetry data being received from the satellite.
The ground infrastructure that supports satellite communications is still a major target for cybercriminals. Mission control networks and data centres are susceptible to malware, ransomware, phishing, and insider threats. Attackers will frequently target ground stations because they provide a connection point to terrestrial networks and can exploit vulnerabilities from the ground station’s IT systems into the satellite control systems. The combination of these threats illustrates the need for an overall security strategy that encompasses all parts of the satellite communications ecosystem.
Key Security Principles and Measures
A comprehensive overview of multiple principles designed to increase the security of satellite communications is provided in the CERT-In Framework on Cybersecurity for Satellite Communications. The first of these principles, security by design, refers to ensuring that all cybersecurity controls associated with a system are implemented at the time of the system's initial design and development, not afterwards; therefore, security controls should be incorporated throughout the entire lifecycle of a satellite system.
The second principle, which is known as Defense-in-Depth, consists of implementing many different layers or tiers of security controls to protect a system against cyber threats or attacks. An example of the different categories of security controls includes physical security, network security, and access control, among others. By combining security controls across multiple categories, an organisation may be able to reduce the chance that one single vulnerability will result in the loss of the entire system.
The third principle in the Framework, Zero Trust Architecture (ZTA): Users and/or devices located within a network should not be able to rely on implicit trust. Therefore, every request for access to the network will be verified and continuously monitored for potential threats.
The previous two principles stated that secure satellite communications should be conducted using strong encryption and authentication methods, as well as secure communications methods, and that an enterprise monitoring system would be put into place to help detect anomalies or suspicious behaviour.
Conclusion
India is taking an important step toward protecting its expanding space ecosystem by creating a cybersecurity framework to safeguard cyberspace systems from cyber threats. The CERT-In guidelines offer a structured means of reducing the likelihood of cyber threats impacting satellite communication infrastructure through secure system design, continuous monitoring of systems and creating consistent partnerships among organisations. As well as providing evidence that both government and private sector organisations share a collective responsibility for the protection of space assets, both sectors participate in a collaborative effort.
India will need to implement rigorous cybersecurity measures as it expands its space infrastructure in order to ensure the continued availability of critical space infrastructure and ultimately develop its existing commercial satellite business operations with the highest level of safety and security.
