Mercury Systems’ RelianceOne™ Security Suite extends defense-grade cyber resiliency to Linux containers in the Aerospace and Defense market, addressing the critical security risks of shared-kernel architectures.

While containerization delivers development agility and efficiency, its unified attack surface leaves systems vulnerable to container breakouts and lateral attacks. RelianceOne™ mitigates these threats by isolating applications into secure "vaults" using Mandatory Access Control policies, protecting image layers with transparent encryption, and utilizing cryptographic key management to restrict workload execution to verified runners.

This comprehensive security model safeguards sensitive software, data, and intellectual property throughout the entire container lifecycle without sacrificing portability or disrupting existing workflows.

Read this white paper to learn about:

Shared-kernel architectures expose containerized systems to breakouts and lateral attacks.
RelianceOne™ brings defense-grade cyber resiliency to Linux containers.
Mandatory Access Control and secure vaults isolate critical code.
Data Protection: Encrypted image layers prevent tampering on compromised registries or hosts.
Key management restricts workload execution strictly to cryptographically verified runners.
