CERT-In & SIA-India Joint Guidelines: Hardening India's Space Infrastructure for the 2026 Threat Landscape
New joint guidelines from CERT-In and SIA-India tighten security for India's space assets. Here is what engineers need to know about the 2026 updates.

The New Guardrails for India's Orbit
The space sector isn't just about rockets anymore. It is about data. It is about connectivity. And it is about security. On April 1, 2026, the landscape shifted significantly. CERT-In and SIA-India released joint guidelines that fundamentally alter the operational paradigm for the Indian space ecosystem. These aren't just suggestions; they are the new standard for operating in the Indian space ecosystem. You need to read them. You need to implement them. The old ways don't work in 2026.
Imagine a satellite ground station. It sits in a remote location. It receives commands. It sends telemetry. Now imagine a hacker intercepting that uplink. The impact isn't just a lost email. It is a loss of national asset. It is a loss of critical data for agriculture, disaster management, and defense. The guidelines address this reality head-on. They recognize that the orbital environment is no longer a vacuum of physical space but a contested digital domain.
Let's get technical immediately. Why do we care about this specific announcement? Because the threat model has changed. It is no longer just about brute force attacks on login pages. We are talking about supply chain compromises. We are talking about firmware integrity. We are talking about the specific protocols used to communicate with orbital assets, such as CCSDS (Consultative Committee for Space Data Systems) and proprietary SCPI interfaces. The guidelines cover these areas. They force a shift in how we think about vulnerability management. They acknowledge that the latency inherent in space communications makes traditional real-time defense mechanisms insufficient, requiring proactive hardening.
Don't wait for a breach to read this. The damage from a compromised satellite control system is catastrophic. Recovery takes months. Rebuilding trust takes years. The guidelines provide a roadmap. They outline the minimum viable security posture required for any entity handling space data. It is a strict requirement for compliance. It is a mandate for safety. In the context of India's growing satellite constellation, including the OneWeb partnership and the Bharatiya Space Mission, this compliance is non-negotiable.
Breaking Down the Technical Mandates
What is actually in the document? It is dense. It is technical. Let's walk through the core pillars. You will see that they align with global best practices but add specific local context relevant to Indian sovereignty and data residency laws. The document is structured around three main pillars: Cryptographic Resilience, Supply Chain Integrity, and Incident Response Protocols. We will dissect each of these in detail.
1. Encryption Standards and Cryptographic Resilience
First, encryption. The guidelines mandate the use of specific algorithms. We are seeing a push away from older standards. AES-256 is the baseline. For the control links, they are recommending Post-Quantum Cryptography (PQC) readiness. Why? Because the timeline for quantum computers is closer than we thought. If you are holding long-term keys for satellite telemetry, you need to be ready for that future. The guidelines explicitly state that any key material stored for longer than 10 years without rotation is considered a high-risk vulnerability.
[Note: Most people get this wrong. They think encryption is just a setting in a config file. It is not. It is a lifecycle management issue.]
The document specifies key rotation intervals. You don't rotate keys every month. You rotate them based on entropy and usage. The guidelines give you the math for that. They also cover the transport layer. TLS 1.3 is the requirement. Anything lower gets flagged during audits. I have seen teams run into trouble with TLS 1.2. It is considered legacy now. Don't risk it. Also,, the guidelines require Hardware Security Modules (HSM) for key generation and storage. Software-based key management is insufficient for critical space infrastructure. The HSM must be FIPS 140-2 Level 3 certified or equivalent. This ensures that even if the server is compromised, the keys remain safe.
Plus,, the guidelines address the issue of Perfect Forward Secrecy (PFS).
