Mapped every skill to NIST CSF 2.0 subcategory IDs (GV/ID/PR/DE/RS/RC functions) based on subdomain and content analysis. Restores 11 skills corrupted during prior rebase, re-enriching with ATLAS, D3FEND, NIST AI RMF, and CSF 2.0 fields. All 754 skills now carry structured mappings for all 5 security frameworks: - MITRE ATT&CK (in tags) - MITRE ATLAS v5.5 (atlas_techniques) - MITRE D3FEND v1.3 (d3fend_techniques) - NIST AI RMF 1.0 (nist_ai_rmf) - NIST CSF 2.0 (nist_csf)

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
