In 2025, cybersecurity isn’t just a technical issue—it’s a business imperative. The Cybersecurity Maturity Model Certification (CMMC) has raised the bar by requiring a culture of cybersecurity for all organizations within the DoD supply chain
Why? Because 95% of cybersecurity incidents are primarily due to human error. That means the biggest risk to your business might not be a hacker—it could be an employee who clicks the wrong link.
And CMMC is turning up the heat. With the Department of Defense planning to enforce CMMC 2.0 across 300,000+ contractors, organizations are being pushed to embed security into their culture, not just their systems.
In this article, we’re breaking down the must-have elements of a real, working cybersecurity culture that meets CMMC requirements and protects your business.
What is Cybersecurity Culture?
Cybersecurity culture is an organization’s collective mindset, behavior, and actions towards protecting its information systems and data. It goes beyond just having a set of security policies in place or implementing technical controls – it’s about cultivating a security-conscious attitude and incorporating it into every aspect of the business.
A security-minded thinking should be present at all levels of an organization, from the top-level executives to the front-line employees.
The key components of a strong security culture include:
- Awareness and Education
- Accountability and Responsibility
- Adopting Best Practices
- Engagement and Participation
- Continuous Improvement
With a strong security culture, employees will be more vigilant and proactive in identifying potential threats and adhering to security protocols. This ultimately leads to a safer and more secure environment for the organization.
How to Build a CMMC-Driven Cybersecurity Culture (9 Key Elements)
Executive buy-in and leadership
Cybersecurity culture starts at the top. Executive leadership must be fully committed to building and promoting a strong security culture within the organization. If the C-suite treats CMMC like a box to check off, employees will likely follow suit and see security as a burden or a hindrance to their work.
For a CMMC-driven cybersecurity culture to thrive, executives must actively participate in and support security initiatives. They must also be willing to allocate adequate resources and budget to support the implementation of security controls and training programs. A top-down approach to security can also help create a sense of accountability and responsibility for cybersecurity throughout the organization.
Employee engagement and awareness
Security is every employee’s responsibility, not just the IT department. Employees are often the first line of defense against cyber threats and must be educated on how to identify and report potential security incidents.
Ongoing, and role-specific training help build habits for employees to act in accordance with the organization’s cybersecurity policies and procedures. Regularly scheduled, interactive training sessions can serve as a refresher on security best practices.
For example, employees could be trained on how to identify phishing emails or what steps to take if they suspect a data breach. The training should also emphasize the importance of strong password management and the dangers of using public Wi-Fi networks. Additionally, employees should be educated on how to handle sensitive data, both in physical and digital forms.
Policies and procedures aligned to CMMC
CMMC demands more than just technical controls for data security. It requires organizations to have written policies and procedures for managing sensitive information. This includes policies related to access control, incident response, data encryption, and more.
The policies should be easy to understand and implement, so all employees know their responsibilities and obligations when handling sensitive data. A practicable and effective approach to this is having a comprehensive set of security procedures regularly reviewed, updated, and communicated to employees.
Organizations should also have a system for monitoring and enforcing compliance with these policies and procedures. Regular audits and assessments can help identify any gaps or weaknesses in the security measures and allow for necessary improvements.
Continuous monitoring and accountability
Security isn’t “set it and forget it.” It’s a living, breathing process that requires constant attention and updates. Dashboards, alerts, and regular reporting can help organizations stay on top of potential security threats and vulnerabilities. KPIs and auditable metrics can provide a measurable way to track progress and identify areas for improvement.
For instance, penetration testing can help identify gaps in the current security measures and allow for necessary improvements. And regular audits can ensure that security protocols are being followed and maintained.
Rewarding team members for maintaining a secure environment can encourage accountability and lead to a culture of security within the organization. Regular training and education on new threats and best practices can also help keep employees informed and vigilant.
Data-centric mindset
CMMC protects Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). This requires a data-centric mindset where all data is treated as sensitive and protected. The focus shifts from just securing the network to securing the data itself. Build a culture where data is valued and protected, regardless of classification level.
In a data-centric mindset, data is classified based on its sensitivity and criticality to the organization. A least privilege approach is applied, where only authorized users can access specific data based on their need-to-know. With this approach, data is protected even if there is a security breach or unauthorized access to the network.
Another aspect of a data-centric mindset is implementing strong encryption methods for sensitive data. The use of encryption ensures that even if data is intercepted, it cannot be read or used without the proper decryption key. This adds an extra layer of protection to sensitive data and helps prevent breaches.
Incident preparedness and response
When something goes wrong, a culture determines how an organization responds to the incident. An organization should have a well-defined incident response plan outlining handling security incidents and minimizing damage. This plan should include steps for identifying, containing, eradicating, and recovering from an incident.
Train employees to respond fast and effectively to a security incident. Everyone should know their role in the event of an incident and be aware of any reporting processes. Test your plan with a tabletop exercise to identify weaknesses and improve your response plan. Regularly review and update the plan as needed to ensure it is effective against evolving threats.
A culture to reward transparency over secrecy and encourage reporting of potential security incidents should also be fostered. Employees should feel comfortable reporting suspicious activity or breaches without fear of reprimand.
Integration into daily operations
The day-to-day operations of an organization should also incorporate security practices. This includes integrating security considerations into developing and deploying new systems, applications, and processes.
For example, security testing and vulnerability assessments should be conducted to identify potential risks before launching a new website or implementing a new software system. Regular backups of important data should also be performed to minimize the impact of a cyber attack.
Use tools and processes that secure-by-default workflows, such as encryption and strong password policies. This means that security measures are integrated into the development process from the very beginning, rather than being an afterthought.
Managing third-party and supply chain risk
CMMC expects you to assess, vet, and hold your partners and vendors to the same security standards you adhere to for your organization. This is important because any vulnerabilities in their systems could potentially impact your own cybersecurity posture.
To manage third-party and supply chain risk, here are some best practices to follow:
- Conduct a thorough risk assessment before entering into business relationships with third parties and suppliers.
- Include specific language addressing cybersecurity requirements in contracts and service-level agreements (SLAs).
- Regularly review and monitor the security controls of your partners and vendors.
- Conduct audits or assessments of their systems periodically to ensure compliance with your agreed-upon security standards.
- Implement a vendor risk management program that includes vetting, onboarding, and ongoing monitoring of third parties and suppliers.
- Provide training or resources to vendors and partners on proper security practices to minimize overall risk.
- Establish contingency plans in case of a breach or disruption caused by a third party or supplier.
Extend your security culture to partners and vendors by implementing a vendor risk management program for a comprehensive approach to managing third-party risks.
The long-term ROI of cybersecurity culture
When you build a strong security culture, you reduce breaches, increase resilience, and earn trust with customers and regulators. Additionally, investing in cybersecurity culture can have long-term financial benefits for your organization.
You can save your organization from costly remediation efforts by preventing cyberattacks and data breaches. This can save your organization millions in potential damages, legal fees, and reputational damage. In contrast, not investing in cybersecurity culture can result in huge financial losses due to data breaches and cyberattacks.
Investing in cybersecurity culture also allows you to demonstrate your commitment to protecting your customers’ sensitive data. As a result, you can win more business and maintain strong relationships with existing clients.
Conclusion
Technology can only take you so far. Firewalls, encryption, and access controls are critical—but they’re not enough without the right behaviors behind them.
A CMMC-driven cybersecurity culture isn’t just about passing an audit. It’s about creating a workplace where security is second nature, and every employee knows they have a role to play in protecting sensitive data. Compliance becomes easier when leadership leads, employees stay engaged, and secure habits are part of daily operations.
This kind of culture takes intention, time, and buy-in from the top down. But the ROI? Fewer breaches, stronger customer trust, and a big edge when winning government contracts.
