Mtls Zero Trust Services

Configures mutual TLS (mTLS) authentication between microservices using Python cryptography library for certificate generation and ssl module for TLS verification. Validates certificate chains, checks expiration, and audits mTLS deployment status. Use when implementing zero-trust service-to-service authentication.

Implementing mTLS for Zero Trust Services

When to Use

When deploying or configuring implementing mtls for zero trust services capabilities in your environment
When establishing security controls aligned to compliance requirements
When building or improving security architecture for this domain
When conducting security assessments that require this implementation

Prerequisites

Familiarity with security operations concepts and tools
Access to a test or lab environment for safe execution
Python 3.8+ with required dependencies installed
Appropriate authorization for any testing activities

Instructions

Generate CA certificates, issue service certificates, and configure mutual TLS verification for service-to-service authentication.

from cryptography import x509
from cryptography.x509.oid import NameOID
from cryptography.hazmat.primitives import hashes, serialization
from cryptography.hazmat.primitives.asymmetric import rsa
import datetime

# Generate CA key and certificate
ca_key = rsa.generate_private_key(public_exponent=65537, key_size=4096)
ca_cert = (x509.CertificateBuilder()
    .subject_name(x509.Name([x509.NameAttribute(NameOID.COMMON_NAME, "Internal CA")]))
    .issuer_name(x509.Name([x509.NameAttribute(NameOID.COMMON_NAME, "Internal CA")]))
    .public_key(ca_key.public_key())
    .serial_number(x509.random_serial_number())
    .not_valid_before(datetime.datetime.utcnow())
    .not_valid_after(datetime.datetime.utcnow() + datetime.timedelta(days=3650))
    .add_extension(x509.BasicConstraints(ca=True, path_length=None), critical=True)
    .sign(ca_key, hashes.SHA256()))

Examples

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.load_cert_chain("client.pem", "client-key.pem")
context.load_verify_locations("ca.pem")
context.verify_mode = ssl.CERT_REQUIRED
