2. What is FIPS 140?
2.1 FIPS 140 Explained
FIPS 140 is a US government standard for cryptographic modules. It stands for Federal Information Processing Standard Publication 140. This standard checks and approves the hardware, software, or firmware that do cryptographic tasks. FIPS 140 makes sure these modules are secure enough to protect sensitive data.
2.2 Main Parts of FIPS 140
FIPS 140 has four key areas:
| Area | Description |
|---|---|
| Security Requirements | Rules for how cryptographic modules should work to be secure |
| Module Validation | Testing process to check if modules meet security rules |
| Algorithm Validation | Testing process to check if the math formulas used are correct |
| Physical Security | Rules for how to protect the actual hardware of the modules |
2.3 FIPS 140 Security Levels
FIPS 140 has four security levels, from Level 1 (basic) to Level 4 (strongest):
| Level | Features |
|---|---|
| 1 | Basic design and testing |
| 2 | Adds physical security (e.g., locks) |
| 3 | Adds protection against environment (e.g., temperature) |
| 4 | Highest security, protects against complex attacks |
Each level builds on the one before it, adding more security features.
3. What is CMMC?
3.1 CMMC Explained
CMMC stands for Cybersecurity Maturity Model Certification. It's a standard set by the US Department of Defense (DoD) to check how well organizations protect sensitive data. This includes:
- Controlled Unclassified Information (CUI)
- Federal Contract Information (FCI)
CMMC uses five levels to measure an organization's cybersecurity skills.
3.2 CMMC Maturity Levels
CMMC has five levels, each showing better cybersecurity:
| Level | What it Means |
|---|---|
| 1 | Basic cyber safety |
| 2 | Better cyber safety |
| 3 | Good cyber safety |
| 4 | Strong cyber safety |
| 5 | Top cyber safety |
Each level adds more security measures to the one before it.
3.3 CMMC Cryptography Rules
CMMC has specific rules for cryptography:
| Rule | Description |
|---|---|
| Use approved methods | Only use cryptography methods that are okay'd by experts |
| Manage keys safely | Keep the "keys" that unlock encrypted data very safe |
| Protect data | Keep data safe when it's being sent and when it's stored |
| Use safe communication | Use secure ways to send data, like HTTPS and SFTP |
CMMC also says organizations need a plan for how they'll use and manage cryptography.
These rules help make sure that sensitive data stays safe from:
- People who shouldn't see it
- Changes that shouldn't happen
- Being destroyed
By following these rules, organizations can keep their data safe and follow DoD rules.
Next, we'll look at how FIPS 140 and CMMC cryptography rules are alike and different.

6. How FIPS 140 and CMMC Are Similar
6.1 Common Security Goals
FIPS 140 and CMMC both aim to keep sensitive information safe. They do this by:
- Stopping people who shouldn't see the data from seeing it
- Making sure no one changes the data without permission
- Checking that the data is real and hasn't been faked
Both standards focus on:
- Keeping encryption keys safe
- Using good ways to encrypt and decrypt data
- Checking security often to make sure it's working well

Both FIPS 140 and CMMC use these features to make sure data stays safe and private.
7. What This Means for Organizations
7.1 Choosing Between FIPS 140 and CMMC
When deciding which standard to follow, organizations should look at their specific needs:
| Standard | Best For | Key Features |
|---|---|---|
| FIPS 140 | Government agencies and contractors | • Clear rules for cryptographic tools • Often needed for federal contracts |
| CMMC | DoD contractors and suppliers | • Focuses on overall cybersecurity • Required for DoD work |
Organizations should pick based on their main work and clients. Those working with general government agencies might prefer FIPS 140, while those in defense should choose CMMC.
7.2 Following Both Standards
Some organizations might need to follow both FIPS 140 and CMMC. This can be tricky, but there are ways to make it easier:
- Find where the standards overlap
- Make a plan that covers both sets of rules
- Use tools that meet both standards' requirements
- Check and update the plan regularly
By doing these things, organizations can meet both standards without doubling their work.
7.3 Costs and Resources Needed
Following FIPS 140 and CMMC takes time and money. Organizations need to think about:
| Cost Area | Examples |
|---|---|
| Tools and practices | Buying and using secure software and hardware |
| Training | Teaching staff about the standards |
| Checks | Regular security tests |
| Updates | Keeping everything up to date |
The exact costs depend on how big the organization is and what security they already have. To plan for these costs, organizations should:
- Check what they need to improve
- Make a detailed plan
- Set a budget and timeline
- Keep checking and updating their plan
While it costs money to follow these standards, it helps keep data safe and builds trust with customers and partners.
