10 Essential Cybersecurity Practices for Any Business 

Even if your business doesn’t work with the Department of Defense, many CMMC practices are universally valuable. They’re basically best practices for good cybersecurity hygiene — and in today’s world, every business needs that. 

Here are 10 CMMC-related practices that can help any business, no matter the industry: 

  1. Use Strong Passwords and Multi-Factor Authentication (MFA)
  • Encourage or require complex passwords. 
  • Add MFA wherever possible — especially for email, cloud apps, and admin accounts. 

Why it helps: Stops unauthorized access if a password is stolen or guessed. 

 

  1. Keep Software and Systems Updated
  • Apply security patches regularly. 
  • Set automatic updates for operating systems and software. 

Why it helps: Old systems are a hacker’s playground. 

 

  1. Limit Access to Sensitive Data
  • Only give employees access to what they need (aka “least privilege”). 
  • Remove old accounts and permissions when employees leave or change roles. 

Why it helps: Cuts the risk of accidental or malicious data exposure. 

 

  1. Back Up Your Data — Regularly
  • Perform automatic, encrypted backups of critical systems and files. 
  • Test recovery processes (so you’re not guessing when disaster strikes). 

Why it helps: Helps you recover from ransomware, accidental deletions, or server failures. 

 

  1. Install and Maintain Antivirus/Antimalware Protection
  • Use reputable endpoint protection tools. 
  • Scan regularly and set alerts for suspicious activity. 

Why it helps: Protects against common malware and viruses that can compromise your systems. 

 

  1. Train Employees on Cyber Awareness
  • Teach employees how to spot phishing emails. 
  • Reinforce safe internet habits and reporting anything suspicious. 

Why it helps: People are often the weakest link — training turns them into a line of defense. 

 

  1. Create an Incident Response Plan
  • Know what to do if your business gets hacked, including who to call and what steps to take. 
  • Include backups, legal contacts, and communication steps. 

Why it helps: You’ll recover faster and limit damage if something goes wrong. 

 

  1. Log and Monitor Activity
  • Track who is logging in and what systems they access. 
  • Look for unusual behavior (e.g., someone logging in at 2 a.m. from a new location). 

Why it helps: Detects breaches early before they cause major harm. 

 

  1. Use a Firewall and Secure Your Wi-Fi
  • Make sure your network is segmented and protected with a strong firewall. 
  • Change default router passwords and use encryption (WPA3 recommended). 

Why it helps: Keeps intruders out and protects internal systems. 

 

  1. Document Your Security Policies
  • Have written policies for how you handle data, employee access, remote work, etc. 
  • Update them regularly and review with your team. 

Why it helps: Creates consistency, accountability, and compliance readiness (for future growth). 

 

Bonus: Review Your Vendors' Security Too 

If your business relies on cloud services or contractors, make sure they take cybersecurity seriously. 

Why it helps: A weak vendor can become a back door into your systems. 

 

Bottom Line: You don’t have to be a defense contractor to benefit from CMMC practices. These are smart, scalable actions that: 

  • Improve your resilience 
  • Protect your brand and customer trust 
  • Prepare your business for bigger opportunities down the road
