๐ Scenario 02: Chaos Attacks Your Secrets!
"Python Security Hero Defeats Database Chaos!"
๐ SCENARIO OVERVIEW
The Security Challenge
Chaos Agent has escalated their attack! They've discovered that manual secret management is a security nightmare. Plain text passwords in YAML files, databases exposed to the internet, and missing security configurations have left your infrastructure vulnerable to data theft, ransomware attacks, and compliance violations.
The Security Hero Solution
Deploy an enterprise-grade secret management system using Python automation that generates cryptographically secure passwords, implements automated secret rotation, and provides real-time security monitoring. No more exposed credentials, no more security chaos!

- ๐ Enterprise Secret Management with automated generation
- ๐ Secure Todo Application with encrypted database storage
- ๐ Zero-Downtime Secret Rotation system
- ๐๏ธ Real-time Security Monitoring dashboard
- ๐ก๏ธ Production-Grade Security controls and compliance

๐งจ THE CHAOS AGENT'S SECURITY ATTACK
"Your database passwords are EXPOSED! I can see them in plain text in your YAML files! I'll steal your data and crash your databases! Your manual secret management is a security nightmare!" ๐๐
What Chaos Agent Exploits: - โ Plain text passwords visible in YAML files and Git repositories - โ Database services exposed directly to the internet - โ No secret rotation = permanent compromise after breach - โ Missing security contexts = privilege escalation attacks - โ No audit trails = invisible security violations - โ Resource exhaustion = denial of service vulnerabilities
๐ฆธโโ๏ธ THE PYTHON SECURITY HERO'S RESPONSE
"Not today, Chaos Agent! Python-powered secret automation will protect our data with enterprise-grade security. Watch as I deploy bulletproof secret management!" ๐ฆธโโ๏ธ๐
How Python Security Hero Wins: - โ Cryptographically secure password generation - Unbreakable credentials - โ Kubernetes Secrets encryption - No plain text storage ever - โ Automated secret rotation - Credentials change regularly - โ Network isolation - Database internal-only access - โ Security contexts - Non-root execution, dropped privileges - โ Resource limits - Prevent DoS attacks - โ Comprehensive monitoring - Real-time security status - โ Audit trails - Complete security metadata tracking

namespace: secure-todo
spec:
type: ClusterIP # Internal only
selector:
app: mysql
ports:
- port: 3306
targetPort: 3306
4. Security Contexts
# Non-root execution with dropped privileges
securityContext:
runAsNonRoot: true
runAsUser: 1000
runAsGroup: 1000
allowPrivilegeEscalation: false
capabilities:
drop:
- ALL
๐งช SECURITY TESTING

# Check that secrets are encrypted
kubectl get secret mysql-secret -n secure-todo -o yaml
# Verify no plain text passwords
kubectl get secret mysql-secret -n secure-todo -o jsonpath='{.data.password}' | base64 -d
Test 2: Network Isolation Test
# Verify database is internal-only
