Thales – Secure Communications,
Critical Infrastructure & Defence IT

The Challenge

Defence and critical infrastructure environments depend on secure and reliable communications to support essential operations.

These environments must protect sensitive information while maintaining connectivity across complex networks, distributed locations and multiple technology platforms.

The challenge was to establish security architectures capable of protecting communications and data without compromising the availability and performance required by mission-critical systems.

Secure Communications

Sensitive communications require protection throughout their lifecycle, from initial transmission through processing and storage.

Security needed to be incorporated across communications infrastructure to reduce exposure and maintain confidentiality across interconnected environments.

Network Security

Complex networks create multiple potential points of exposure.

Strong segmentation, access controls and security architecture were required to reduce risk while maintaining reliable communication between authorised systems and users.

Identity & Access Management

Access to sensitive systems and information needed to be tightly controlled.

Identity architectures had to provide secure authentication and authorisation while supporting users operating across distributed technology environments.

Operational Resilience

Critical infrastructure and defence systems must remain available even when facing disruption, technology failures or cyber threats.

Architectures therefore needed to consider resilience and continuity alongside traditional security requirements.

AI Core X Contribution

AI Core X expertise supported an integrated approach combining secure communications, network security, encryption architecture and identity management.

Security principles were incorporated throughout system and network architecture, helping establish multiple layers of protection around sensitive communications, infrastructure and information.

The approach focused on creating technology environments capable of maintaining strong security while supporting the operational requirements of complex defence and critical infrastructure systems.

Secure Communications Architecture

Secure communication environments require protection across every stage of information exchange.

Architecture principles were applied to help protect communications between authorised users, applications and systems while reducing opportunities for interception or unauthorised access.

End-to-End Protection

Security controls were incorporated across communications pathways to protect information as it moved between systems and environments.

Secure Connectivity

Network architectures supported controlled communication between distributed locations, infrastructure and authorised technology resources.

Communications Resilience

Architecture was designed with availability and continuity in mind, helping communications environments remain dependable during operational disruption.

Network & Data Protection

Protecting sensitive information requires coordinated security across both network infrastructure and the data travelling through it.

AI Core X expertise contributed to architectures designed to strengthen protection across these interconnected layers.

Network Segmentation

Segmentation principles helped separate systems and security zones according to operational requirements and risk.

This can limit unnecessary connectivity and reduce the potential impact of compromised systems.

Encryption Architecture

Encryption principles were incorporated to protect sensitive information both during transmission and while stored within technology environments.

Data Security

Access controls and security policies helped establish appropriate boundaries around sensitive information and critical technology resources.

Identity & Access Management

Identity is fundamental to protecting modern distributed technology environments.

AI Core X expertise supported identity architectures designed to ensure that users, applications and systems could access resources according to clearly defined permissions.

Secure Authentication

Strong authentication principles helped establish greater confidence that users and systems accessing protected resources were appropriately verified.

Access Control

Role-based and least-privilege approaches helped limit access according to operational responsibilities and security requirements.

Identity Federation

Federated identity approaches supported secure access across interconnected systems while reducing unnecessary identity complexity.

Information Assurance & Governance

Security within defence and critical infrastructure environments extends beyond individual technologies.

Effective protection requires structured governance, clearly defined responsibilities and controls that address how information is accessed, processed, transferred and protected.

Information assurance principles were incorporated into architecture and engineering activities to help maintain the confidentiality, integrity and availability of sensitive information.

This created a stronger foundation for secure operations while supporting evolving technology and operational requirements.

Cyber Resilience for Critical Environments

Cyber resilience requires organisations to prepare not only to prevent incidents, but also to maintain critical operations when disruption occurs.

Architectural decisions therefore considered security alongside availability, redundancy, recovery and operational continuity.

By incorporating resilience into the underlying technology architecture, critical environments can be better prepared to respond to changing threats without compromising essential services.
