- Add validated mitre_attack frontmatter to all 754 skills (286 distinct techniques), verified against MITRE ATT&CK v19.1 via the official mitreattack-python library: 0 revoked, deprecated, or invalid IDs - Curate precise per-skill technique IDs for forensics, malware-analysis, threat-intel, and red-team skills (e.g. DCSync -> T1003.006, Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003) - Reconcile v19.1 tactic restructuring: Defense Evasion split into Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.* family and T1070.001/.002 remapped to active equivalents (T1685.*) - Normalize word-split tags across 35 skills (remove filename-derived stopword tags, add semantic cybersecurity tags) - Add api-reference.md for 3 skills that were missing it - Update README ATT&CK section with accurate v19.1 tactic distribution

# 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() + datetime.timedelta(days=3650))
|
|
.add_extension(x509.BasicConstraints(ca=True, path_length=None), critical=True)
|
|
.sign(ca_key, hashes.SHA256()))
|
|
```
|
|
|
|
## Examples
|
|
|
|
```python
|
|
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
|
|
```
