What is FIPS 140-2?

Standard Definition

FIPS 140-2 is a standard developed by the National Institute of Standards and Technology (NIST) that defines security requirements for cryptographic modules. This standard defines security levels for cryptographic hardware and software components to protect sensitive information.

Security Levels

FIPS 140-2 defines four different security levels:

Level	Description	Security Features
Level 1	Basic security	Approved cryptographic algorithm
Level 2	Enhanced security	Role-based authentication
Level 3	High security	Tamper-evident features
Level 4	Highest security	Tamper-responsive features

FIPS Mode Configuration

System Requirements

For FIPS mode operation, the system must meet the following requirements:

Hardware Requirements

Minimum Hardware:
├── CPU: Intel AES-NI support
├── RAM: 32 GB (for FIPS operations)
├── Disk: Hardware encryption support
├── Network: Dedicated crypto processor
└── Storage: Encrypted storage unit

Software Requirements

System Software:
├── OS: FIPS 140-2 approved Linux kernel
├── OpenSSL: FIPS 140-2 validated module
├── Database: TDE (Transparent Data Encryption)
├── Container: FIPS-compliant Docker runtime
└── Monitoring: FIPS audit trail

Cryptographic Configuration

Master Key Creation

# Master key creation with FIPS approved random number generator
openssl rand -hex 32 > /secure/master.key

# Key verification
openssl dgst -sha256 -verify pubkey.pem -signature master.sig master.key

# Secure file system transfer
install -m 600 -o keycyte -g keycyte master.key /etc/keycyte/secure/

Password Encryption Process

# FIPS compliant password encryption
import cryptography.fernet
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC

# Encryption key derived from master key
kdf = PBKDF2HMAC(
    algorithm=hashes.SHA256(),
    length=32,
    salt=organization_salt,
    iterations=100000,
)

# AES-256 encryption
cipher = Fernet(kdf.derive(master_key))
encrypted_password = cipher.encrypt(plain_password.encode())
