Technical Glossary

Primary coverage is for defense suppliers, constrained environments, and high-assurance compliance work. Broader security and adjacent industry terms remain available lower in the archive.

Glossary Focus

This glossary is not meant to be a generic cyber dictionary. The primary layer exists to support defense delivery, supply-chain trust, regulatory pressure, and architecture decisions in high-control environments. More general or adjacent terms remain accessible as secondary reference.

These are the glossary entries that map most directly to Alterra's core delivery work across constrained environments, secure architecture, and audit-heavy engineering.

Defense

Air-Gapped Networks

Foundational term for disconnected systems, secure update chains, and offline delivery constraints.
Architecture

Zero Trust Architecture

Useful when teams need to define trust boundaries, segmentation, and access assumptions under scrutiny.
Compliance

NIST 800-53

Core reference point for teams aligning controls, evidence, and remediation plans.
Supply Chain

SBOM

Key term for software provenance, dependency visibility, and release integrity discussions.
Primary Terms

Core terms for defense and high-assurance teams

Adjacent Archive

Broader security and past-adjacent terminology

These entries remain accessible because they reflect broader research or earlier adjacent work. They are still useful, but they are no longer meant to define the brand at first glance.
