NSA and ASD's ACSC Release LEO SATCOM Cybersecurity Guidance
March 24, 2026
The National Security Agency (NSA) and the Australian Signals Directorate's Australian Cyber Security Centre (ASD's ACSC), in collaboration with international partners, have jointly issued detailed cybersecurity guidance addressing risks and mitigation strategies for Low Earth Orbit (LEO) satellite communication (SATCOM) systems. This guidance highlights the growing importance of securing LEO SATCOM infrastructure, which supports critical government and private sector communications and emergency network resilience. The release underscores the expanding attack surface posed by increasing LEO satellite constellations and the necessity for robust cybersecurity measures to protect these systems.
- Why this matters: Procurement professionals should anticipate increased requirements for cybersecurity solutions tailored to LEO SATCOM systems in upcoming contracts and solicitations.
- Agencies and contractors involved in satellite communications and cybersecurity must align with the recommended mitigation strategies to meet evolving security standards.
- This guidance signals potential growth in demand for specialized cybersecurity services and technologies focused on space-based communication infrastructure.
- Organizations supporting government and allied international partners should evaluate their current capabilities against this guidance to remain competitive in future procurements.
LEO SATCOM systems improve network resilience and enable emergency communications across both government and private sectors; however, as LEO satellite constellations grow, the attack surface open to adversaries increases, significantly increasing the risk to the system if the correct cybersecurity measures are not applied.
