• Inheritance and Common Controls – Understanding how to leverage enterprise-level security controls to streamline system-level authorizations.

Example scenarios:

• Walk us through how you would handle an audit where a critical security control is found to be non-compliant, but fixing it immediately would take a vital system offline.
• How do you design a continuous monitoring strategy for an application deployed in a hybrid-cloud environment?

System Hardening & Vulnerability Management

You must show that you possess the technical depth required to secure systems against modern threat vectors. This involves understanding both the tools used to find vulnerabilities and the engineering required to fix them.

Be ready to go over:

• Vulnerability Scanning Tools – Hands-on experience with tools like Nessus, ACAS, or Fortify, and how to interpret their outputs.
• STIG Implementation – The process of applying and testing Defense Information Systems Agency (DISA) Security Technical Implementation Guides.
• Patch Management – Strategies for deploying software updates and security patches across distributed, highly secure networks without causing downtime.

Advanced concepts (less common):

• Securing containerized workloads (e.g., Kubernetes, Docker) within classified environments.
• Designing cross-domain solutions (CDS) to safely transfer data between networks of different classification levels.

Cybersecurity Project Engineering

For project-focused roles, you will be evaluated on your ability to manage security milestones within larger systems engineering lifecycles.

Be ready to go over:

• Security-by-Design – Integrating security requirements into the initial phases of system development rather than treating them as an afterthought.
• Milestone Tracking – Managing the technical schedule of an authorization package to align with broader program milestones.
• Technical Writing – Producing clear, unambiguous technical documentation that can withstand rigorous third-party assessment.
