The Challenge
Business Problem
Static secrets are a major security risk. Teams forget to rotate credentials, share API keys in code, and lack visibility into who has access to what.
The Approach
Solution Overview
Connect HashiCorp Vault, AWS Secrets Manager, and GitHub MCP Servers to automate secret rotation, detect leaked credentials, and manage access policies.
Step-by-Step
Implementation Steps
1
Inventory Secrets
Scan all repositories and infrastructure for hardcoded secrets and API keys.
2
Centralize in Vault
Migrate secrets to HashiCorp Vault with proper access policies and TTLs.
3
Automate Rotation
Set up automatic rotation for database passwords, API keys, and certificates.
async function rotateSecret(secretPath) {
const newValue = generateSecureSecret();
await vault.kvPut({ path: secretPath, data: { value: newValue } });
const consumers = await getSecretConsumers(secretPath);
for (const consumer of consumers) {
await updateConsumer(consumer, newValue);
}
await slack.sendMessage({ channel: '#security', text: `Secret ${secretPath} rotated successfully` });
}4
Monitor for Leaks
Use TruffleHog to continuously scan repositories for accidentally committed secrets.

Code Examples

Rotation Scheduler
async function checkRotationSchedule() {
const secrets = await vault.kvList({ path: 'secret/production' });
for (const secret of secrets) {
const metadata = await vault.kvGet({ path: secret });
const daysSinceRotation = daysBetween(metadata.created_time, new Date());
if (daysSinceRotation > 90) await rotateSecret(secret);
}
