# 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. ```python 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() + dateti...
