2. AI Security: Protecting the Intelligence Behind the Infrastructure
Step-by-step guide explaining what this does and how to use it.
AI systems now drive everything from predictive maintenance in OT environments to security analytics in SOCs. Implementing robust security for these systems requires understanding attack vectors unique to machine learning pipelines.
Implementing AI Model Security:
1. Input validation and sanitization for ML models
import re
import json
from typing import Dict, Any
def validate_input(input_data: Dict[str, Any]) -> Dict[str, Any]:
"""Sanitize and validate input before model inference"""
Check for injection attempts
pattern = r'[\x00-\x1f]|\x7f'
for key, value in input_data.items():
if isinstance(value, str):
if re.search(pattern, value):
raise ValueError(f"Invalid character in {key}")
Remove any encoded sequences
input_data[bash] = value.replace('%00', '').replace('\\x00', '')
return input_data
2. Model encryption and secure storage
from cryptography.fernet import Fernet
import os
def secure_model_encryption(model_path: str) -> None:
"""Encrypt trained model files at rest"""
key = Fernet.generate_key()
cipher_suite = Fernet(key)
with open(model_path, 'rb') as file:
model_data = file.read()
encrypted_data = cipher_suite.encrypt(model_data)
Store key in secure vault (Azure Key Vault/AWS KMS)
with open(f"{model_path}.enc", 'wb') as file:
file.write(encrypted_data)
os.remove(model_path)
Protecting Against AI Adversarial Attacks:
Adversarial robustness toolkit installation
pip install adversarial-robustness-toolbox
pip install foolbox
Continuous monitoring for model drift
python -c "
import datetime
import numpy as np
from art.estimators.classification import SklearnClassifier
Monitor prediction confidence scores
def monitor_drift(predictions, threshold=0.7):
drift_detected = np.mean(predictions) < threshold
if drift_detected:
print(f'[bash] Model drift detected at {datetime.datetime.now()}')
Trigger retraining or incident response
return drift_detected
"
3. OT/ICS Security: Protecting Industrial Heritage in the Digital Age
Step-by-step guide explaining what this does and how to use it.

import hashlib
app = Flask(<strong>name</strong>)
redis_client = redis.Redis(host='localhost', port=6379, decode_responses=True)
Rate limiting decorator
def rate_limit(max_calls=100, window_seconds=60):
def decorator(f):
@wraps(f)
def decorated(args, kwargs):
client_ip = request.remote_addr
key = f"rate_limit:{client_ip}:{f.<strong>name</strong>}"
current = redis_client.incr(key)
if current == 1:
redis_client.expire(key, window_seconds)
if current > max_calls:
return jsonify({"error": "Rate limit exceeded"}), 429
return f(args, kwargs)
return decorated
return decorator
JWT validation with dynamic secrets
def token_required(f):
@wraps(f)
def decorated(args, kwargs):
token = request.headers.get('Authorization')
if not token or not token.startswith('Bearer '):
return jsonify({"error": "Invalid token"}), 401
token = token.split(' ')[bash]
try:
Decode with rotating keys
secret_key = redis_client.get('jwt_secret_key')
if not secret_key:
secret_key = os.urandom(32).hex()
redis_client.setex('jwt_secret_key', 3600, secret_key)
data = jwt.decode(token, secret_key, algorithms=['HS256'])
g.user_id = data['user_id']
except Exception as e:

Windows Vulnerability Remediation Automation:
1. Automated patch deployment with WSUS
$session = New-Object -ComObject Microsoft.Update.Session
$searcher = $session.CreateUpdateSearcher()
$criteria = "IsInstalled=0 and Type='Software'"
$updates = $searcher.Search($criteria).Updates
if ($updates.Count -gt 0) {
$downloader = $session.CreateUpdateDownloader()
$downloader.Updates = $updates
$downloader.Download()
$installer = $session.CreateUpdateInstaller()
$installer.Updates = $updates
$result = $installer.Install()
if ($result.ResultCode -eq 2) {
Write-Host "Patches installed successfully. Reboot required."
Restart-Computer -Force
