Security Assessment (CA): The Backbone of Your Continuous Improvement

The Day the “Clean Report” Didn’t Matter

Last year, a small defense manufacturer in Wisconsin celebrated passing their annual IT audit with flying colors. The report looked perfect – no major findings… systems all patched… policies updated. Six months later, a ransomware attack shut down production for two weeks.

When investigators dug in, they discovered the issue wasn’t missed patches or weak passwords. It was that no one had been checking whether their security actually worked.

The “clean report” had given a false sense of security. Their systems were compliant – but not resilient.

This story plays out again and again across the Defense Industrial Base (DIB). Many SMBs view Security Assessment (CA) as an administrative checkbox (e.g., documentation, spreadsheets, reports), but in reality, it’s the heartbeat of your cybersecurity program.

Done right, CA doesn’t just prove you are compliant. It helps you stay secure, make smarter investments, and protect your most valuable business asset, your ability to deliver for the Department of Defense.

What Meeting the Objectives Might Look Like

At CMMC Level 2, Security Assessment (CA) focuses on ensuring your cybersecurity program is not a “set it and forget it” operation. It’s about verifying that your controls are working and your organization can demonstrate that effectiveness. Here’s what auditors typically expect:

• Documented Assessments: You perform and document periodic assessments of your security controls (at least annually).
• Action Tracking: You develop and manage Plans of Action & Milestones (POA&Ms) to fix deficiencies.
• Continuous Monitoring: You monitor your systems and security program to ensure controls remain effective over time.
• Independent Assessments: You may engage third parties to perform objective reviews or support internal validation

In simple terms: you don’t just write the plan, you test the plan, track the gaps, and prove improvement.

Why It Matters: The Costliest Breach Is the One You Can’t Explain

If you’re a small business in the Defense Industrial Base, your business runs on trust. The Department of Defense trusts that you’ll protect Controlled Unclassified Information (CUI). Your primes trust that you won’t be the weak link in their supply chain.

Here’s what strong Security Assessment practices deliver in business terms:

• Protects Revenue: Passing a CMMC assessment is essential to keeping (and winning) DoD contracts
• Builds Confidence: Demonstrates to primes and customers that you manage risk proactively, not reactively
• Reduces Surprises: Identifies weaknesses before attackers (or auditors) do
• Improves ROI: Ensures your security investments actually work, avoiding wasted spend on ineffective tools or processes
• Strengthens Resilience: Enables faster detection, correction, and recovery from cyber events

In other words, CA is your performance review for cybersecurity, not a punishment, but a path to improvement.

Where Most Companies Slip Up

Even well-intentioned businesses struggle with the Security Assessment family. Here’s where many fall short:

• Assessments without action: Reports get written but not used… findings linger
• Over-reliance on tools: Automated scans replace critical thinking and validation
• Outdated or incomplete POA&Ms: Missing timelines, unclear ownership, or no closure tracking
• “One-and-done” mentality: Assessments done once every couple of years instead of as an ongoing process
• No independent eyes: Internal teams assess their own work – bias and blind spots go unchecked
• Poor documentation: Great work is done, but is not recorded in a way that auditors can verify

Each of these pitfalls weakens your ability to prove (and improve) security performance.

How to Start Strong (and Grow Stronger)

If you’re beginning your journey toward CMMC Level 2, here’s what the bare minimum looks like:

A Starting Point: The Minimum to Meet Compliance

• Perform an internal security assessment (at least annually)
  • Use NIST 800-171A or CMMC Assessment Guides
  • Document evidence for each control (e.g., screenshots, configs, policies)
• Maintain a living POA&M
  • List gaps, responsible parties, due dates, and remediation steps
  • Review monthly to track progress
• Review effectiveness regularly
  • Quarterly spot checks of controls (password policy, backups, logging)
  • Document updates and lessons learned
• Report results to leadership
  • Translate findings into business risks and decisions

This foundation typically satisfies auditors – but it’s still reactive.

The NEX Level: Turning Compliance into Competitive Advantage

Once the basics are in place, elevate your CA program from paperwork to performance with these NEX Level practices:

• Build a Continuous Validation Culture
  • Integrate assessments into everyday operations
  • Assign “control owners” across departments, not just IT
• Automate Wisely
  • Use security dashboards to track control health and remediation progress
  • Automate evidence collection for key metrics like patch compliance or MFA adoption
• Run Internal Purple Team (Red vs. Blue) Exercises
  • Pair attack simulations with response validation (purple teaming)
  • Capture lessons in your POA&M and update procedures
• Involve Executives
  • Hold quarterly “Cyber Program Reviews” like financial reviews
  • Discuss risk reduction and cost-benefit insights, not just technical details
• Engage Independent Assessors Early
  • Use a partner like CyberNEX to perform pre-assessment readiness checks
  • Objective eyes uncover blind spots before the CMMC auditor does
• Turn Results into Roadmaps
  • Treat findings as investment data
  • Budget improvements where they’ll reduce the most risk or cost

At the NEX Level, your assessments stop being about compliance. They become a competitive edge – proof that your business is disciplined, transparent, and trustworthy.

The Factory Floor Lesson

Imagine you run a manufacturing floor. Every machine has gauges showing pressure, temperature, and output. You inspect them weekly – everything looks good.

Then one day, production halts because a hidden belt had been fraying for months – something the gauges couldn’t detect.

That’s what happens when security assessments rely only on reports and not validation.

CA is your maintenance plan for the cybersecurity factory. The gauges (logs, scans, reports) are important – but so are the inspections, tune-ups, and outside experts who spot what your team can’t see.

Takeaway: Security Assessment isn’t about proving you’re perfect – it’s about catching what’s breaking before it breaks you.

FAQs

1. What is the purpose of the Security Assessment family in CMMC 2.0?
The Security Assessment (CA) family exists to ensure organizations aren’t just implementing security controls, but that they’re evaluating how well those controls are working. It focuses on assessing, monitoring, and improving your cybersecurity practices over time. In short, it helps confirm that your systems do what you think they do.

By routinely reviewing and testing controls, documenting results, and correcting weaknesses, you can maintain compliance, strengthen your security posture, and demonstrate to auditors that you take continuous improvement seriously.

2. How often should we perform security assessments?
At a minimum, assessments should be performed annually, but many organizations benefit from doing smaller, targeted reviews quarterly or after major system changes. Regular assessments help you detect drift (e.g., when your security controls start working differently than expected) and fix issues before they become findings in a formal audit.

Think of assessments like preventive maintenance: frequent checkups are faster, cheaper, and far less stressful than waiting until something breaks.

3. What’s the difference between a self-assessment and a third-party assessment?
A self-assessment is performed internally to measure your readiness and identify gaps. It’s required for CMMC Level 1 and encouraged for ongoing compliance at higher levels.

A third-party assessment, required for CMMC Level 2 (bifurcated path) and all Level 3 organizations, is conducted by an accredited C3PAO. These external assessments are more formal and provide validated assurance to the DoD that your security controls are implemented and effective.

In practice, self-assessments help you prepare; third-party assessments prove you’re ready.
