# Secrets Vault Manager
**Tier:** POWERFUL
**Category:** Engineering
**Domain:** Security / Infrastructure / DevOps
---
## Overview
Production secret infrastructure management for teams running HashiCorp Vault, cloud-native secret stores, or hybrid architectures. This skill covers policy authoring, auth method configuration, automated rotation, dynamic secrets, audit logging, and incident response.
**Distinct from env-secrets-manager** which handles local `.env` file hygiene and leak detection. This skill operates at the infrastructure layer — Vault clusters, cloud KMS, certificate authorities, and CI/CD secret injection.
### When to Use
- Standing up a new Vault cluster or migrating to a managed secret store
- Designing auth methods for services, CI runners, and human operators
- Implementing automated credential rotation (database, API keys, certificates)
- Auditing secret access patterns for compliance (SOC 2, ISO 27001, HIPAA)
- Responding to a secret leak that requires mass revocation
- Integrating secrets into Kubernetes workloads or CI/CD pipelines
---
## HashiCorp Vault Patterns
### Architecture Decisions
| Decision | Recommendation | Rationale |
|----------|---------------|-----------|
| Deployment mode | HA with Raft storage | No external dependency, built-in leader election |
| Auto-unseal | Cloud KMS (AWS KMS / Azure Key Vault / GCP KMS) | Eliminates manual unseal, enables automated restarts |
| Namespaces | One per environment (dev/staging/prod) | Blast-radius isolation, independent policies |
| Audit devices | File + syslog (dual) | Vault refuses requests if all audit devices fail — dual prevents outages |
### Auth Methods
**AppRole** — Machine-to-machine authentication for services and batch jobs.
```hcl
# Enable AppRole
path "auth/approle/*" {
capabilities = ["create", "read", "update", "delete", "list"]
}
# Application-specific role
vault write auth/approle/role/payment-service \
token_ttl=1h \
token_max_ttl=4h \
secret_id_num_uses=1 \
secret_id_ttl=10m \
token_policies="payment-service-read"
```
**Kubernetes** — Pod-native authentication via service account tokens.
```hcl
vault write auth/kubernetes/role/api-server \
bound_service_account_names=api-server \
bound_service_account_namespaces=production \
policies=api-server-secrets \
ttl=1h
```
**OIDC** — Human operator access via SSO provider (Okta, Azure AD, Google Workspace).
```hcl
vault write auth/oidc/role/engineering \
bound_audiences="vault" \
allowed_redirect_uris="https://vault.example.com/ui/vault/auth/oidc/oidc/callback" \
user_claim="email" \
oidc_scopes="openid,profile,email" \
policies="engineering-read" \
ttl=8h
```
### Secret Engines
| Engine | Use Case | TTL Strategy |
|--------|----------|-------------|
| KV v2 | Static secrets (API keys, config) | Versioned, manual rotation |
| Database | Dynamic DB credentials | 1h default, 24h max |
| PKI | TLS certificates | 90d leaf certs, 5y intermediate CA |
| Transit | Encryption-as-a-service | Key rotation every 90d |
| SSH | Signed SSH certificates | 30m for interactive, 8h for automation |
### Policy Design
Follow least-privilege with path-based granularity:
```hcl
# payment-service-read policy
path "secret/data/production/payment/*" {
capabilities = ["read"]
}
path "database/creds/payment-readonly" {
capabilities = ["read"]
}
# Deny access to admin paths explicitly
path "sys/*" {
capabilities = ["deny"]
}
```
**Policy naming convention:** `{service}-{access-level}` (e.g., `payment-service-read`, `api-gateway-admin`).

## Cloud Secret Store Integration
### Comparison Matrix
| Feature | AWS Secrets Manager | Azure Key Vault | GCP Secret Manager |
|---------|--------------------|-----------------|--------------------|
| Rotation | Built-in Lambda | Custom logic via Functions | Cloud Functions |
| Versioning | Automatic | Manual or automatic | Automatic |
| Encryption | AWS KMS (default or CMK) | HSM-backed | Google-managed or CMEK |
| Access control | IAM policies + resource policy | RBAC + Access Policies | IAM bindings |
| Cross-region | Replication supported | Geo-redundant by default | Replication supported |
| Audit | CloudTrail | Azure Monitor + Diagnostic Logs | Cloud Audit Logs |
| Pricing model | Per-secret + per-API call | Per-operation + per-key | Per-secret version + per-access |
### When to Use Which
- **AWS Secrets Manager**: RDS/Aurora credential rotation out of the box. Best when fully on AWS.
- **Azure Key Vault**: Certificate management strength. Required for Azure AD integrated workloads.
- **GCP Secret Manager**: Simplest API surface. Best for GKE-native workloads with Workload Identity.
- **HashiCorp Vault**: Multi-cloud, dynamic secrets, PKI, transit encryption. Best for complex or hybrid environments.
### SDK Access Patterns
**Principle:** Always fetch secrets at startup or via sidecar — never bake into images or config files.
```python
# AWS Secrets Manager pattern
import boto3, json
def get_secret(secret_name, region="us-east-1"):
client = boto3.client("secretsmanager", region_name=region)
response = client.get_secret_value(SecretId=secret_name)
return json.loads(response["SecretString"])
```
```python
# GCP Secret Manager pattern
from google.cloud import secretmanager
def get_secret(project_id, secret_id, version="latest"):
client = secretmanager.SecretManagerServiceClient()
name = f"projects/{project_id}/secrets/{secret_id}/versions/{version}"
response = client.access_secret_version(request={"name": name})
return response.payload.data.decode("UTF-8")
```
```python
# Azure Key Vault pattern
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
def get_secret(vault_url, secret_name):
credential = DefaultAzureCredential()
client = SecretClient(vault_url=vault_url, credential=credential)
return client.get_secret(secret_name).value
```

## Secret Rotation Workflows
### Rotation Strategy by Secret Type
| Secret Type | Rotation Frequency | Method | Downtime Risk |
|-------------|-------------------|--------|---------------|
| Database passwords | 30 days | Dual-account swap | Zero (A/B rotation) |
| API keys | 90 days | Generate new, deprecate old | Zero (overlap window) |
| TLS certificates | 60 days before expiry | ACME or Vault PKI | Zero (graceful reload) |
| SSH keys | 90 days | Vault-signed certificates | Zero (CA-based) |
| Service tokens | 24 hours | Dynamic generation | Zero (short-lived) |
| Encryption keys | 90 days | Key versioning (rewrap) | Zero (version coexistence) |
### Database Credential Rotation (Dual-Account)
1. Two database accounts exist: `app_user_a` and `app_user_b`
2. Application currently uses `app_user_a`
3. Rotation rotates `app_user_b` password, updates secret store
4. Application switches to `app_user_b` on next credential fetch
5. After grace period, `app_user_a` password is rotated
6. Cycle repeats
### API Key Rotation (Overlap Window)
1. Generate new API key with provider
2. Store new key in secret store as `current`, move old to `previous`
3. Deploy applications — they read `current`
4. After all instances restarted (or TTL expired), revoke `previous`
5. Monitoring confirms zero usage of old key before revocation
---
## Dynamic Secrets
Dynamic secrets are generated on-demand with automatic expiration. Prefer dynamic secrets over static credentials wherever possible.
### Database Dynamic Credentials (Vault)
```hcl
# Configure database engine
vault write database/config/postgres \
plugin_name=postgresql-database-plugin \
connection_url="postgresql://{{username}}:{{password}}@db.example.com:5432/app" \
allowed_roles="app-readonly,app-readwrite" \
username="vault_admin" \
password="<admin-password>"
# Create role with TTL
vault write database/roles/app-readonly \
db_name=postgres \
creation_statements="CREATE ROLE \"{{name}}\" WITH LOGIN PASSWORD '{{password}}' VALID UNTIL '{{expiration}}'; GRANT SELECT ON ALL TABLES IN SCHEMA public TO \"{{name}}\";" \
default_ttl=1h \
max_ttl=24h
```
### Cloud IAM Dynamic Credentials
Vault can generate short-lived AWS IAM credentials, Azure service principal passwords, or GCP service account keys — eliminating long-lived cloud credentials entirely.
### SSH Certificate Authority
Replace SSH key distribution with a Vault-signed certificate model:
1. Vault acts as SSH CA
2. Users/machines request signed certificates with short TTL (30 min)
3. SSH servers trust the CA public key — no `authorized_keys` management
4. Certificates expire automatically — no revocation needed for normal operations
---
## Audit Logging
### What to Log
| Event | Priority | Retention |
|-------|----------|-----------|
| Secret read access | HIGH | 1 year minimum |
| Secret creation/update | HIGH | 1 year minimum |
| Auth method login | MEDIUM | 90 days |
| Policy changes | CRITICAL | 2 years (compliance) |
| Failed access attempts | CRITICAL | 1 year |
| Token creation/revocation | MEDIUM | 90 days |
| Seal/unseal operations | CRITICAL | Indefinite |
### Anomaly Detection Signals
- Secret accessed from new IP/CIDR range
- Access volume spike (>3x baseline for a path)
- Off-hours access for human auth methods
- Service accessing secrets outside its policy scope (denied requests)
- Multiple failed auth attempts from single source
- Token created with unusually long TTL
### Compliance Reporting
Generate periodic reports covering:
1. **Access inventory** — Which identities accessed which secrets, when
2. **Rotation compliance** — Secrets overdue for rotation
3. **Policy drift** — Policies modified since last review
4. **Orphaned secrets** — Secrets with no recent access (>90 days)
Use `audit_log_analyzer.py` to parse Vault or cloud audit logs for these signals.
---
## Emergency Procedures
### Secret Leak Response (Immediate)
**Time target: Contain within 15 minutes of detection.**
1. **Identify scope** — Which secret(s) leaked, where (repo, log, error message, third party)
2. **Revoke immediately** — Rotate the compromised credential at the source (provider API, Vault, cloud SM)
3. **Invalidate tokens** — Revoke all Vault tokens that accessed the leaked secret
4. **Audit blast radius** — Query audit logs for usage of the compromised secret in the exposure window
5. **Notify stakeholders** — Security team, affected service owners, compliance (if PII/regulated data)
6. **Post-mortem** — Document root cause, update controls to prevent recurrence
### Vault Seal Operations
**When to seal:** Active security incident affecting Vault infrastructure, suspected key compromise.
**Sealing** stops all Vault operations. Use only as last resort.
**Unseal procedure:**
1. Gather quorum of unseal key holders (Shamir threshold)
2. Or confirm auto-unseal KMS key is accessible
3. Unseal via `vault operator unseal` or restart with auto-unseal
4. Verify audit devices reconnected
5. Check active leases and token validity
See `references/emergency_procedures.md` for complete playbooks.

## CI/CD Integration
### Vault Agent Sidecar (Kubernetes)
Vault Agent runs alongside application pods, handles authentication and secret rendering:
```yaml
# Pod annotation for Vault Agent Injector
annotations:
vault.hashicorp.com/agent-inject: "true"
vault.hashicorp.com/role: "api-server"
vault.hashicorp.com/agent-inject-secret-db: "database/creds/app-readonly"
vault.hashicorp.com/agent-inject-template-db: |
{{- with secret "database/creds/app-readonly" -}}
postgresql://{{ .Data.username }}:{{ .Data.password }}@db:5432/app
{{- end }}
```
### External Secrets Operator (Kubernetes)
For teams preferring declarative GitOps over agent sidecars:
```yaml
apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
name: api-credentials
spec:
refreshInterval: 1h
secretStoreRef:
name: vault-backend
kind: ClusterSecretStore
target:
name: api-credentials
data:
- secretKey: api-key
remoteRef:
key: secret/data/production/api
property: key
```
### GitHub Actions OIDC
Eliminate long-lived secrets in CI by using OIDC federation:
```yaml
- name: Authenticate to Vault
uses: hashicorp/vault-action@v2
with:
url: https://vault.example.com
method: jwt
role: github-ci
jwtGithubAudience: https://vault.example.com
secrets: |
secret/data/ci/deploy api_key | DEPLOY_API_KEY ;
secret/data/ci/deploy db_password | DB_PASSWORD
```

## Anti-Patterns
| Anti-Pattern | Risk | Correct Approach |
|-------------|------|-----------------|
| Hardcoded secrets in source code | Leak via repo, logs, error output | Fetch from secret store at runtime |
| Long-lived static tokens (>30 days) | Stale credentials, no accountability | Dynamic secrets or short TTL + rotation |
| Shared service accounts | No audit trail per consumer | Per-service identity with unique credentials |
| No rotation policy | Compromised creds persist indefinitely | Automated rotation on schedule |
| Secrets in environment variables on CI | Visible in build logs, process table | Vault Agent or OIDC-based injection |
| Single unseal key holder | Bus factor of 1, recovery blocked | Shamir split (3-of-5) or auto-unseal |
| No audit device configured | Zero visibility into access | Dual audit devices (file + syslog) |
| Wildcard policies (`path "*"`) | Over-permissioned, violates least privilege | Explicit path-based policies per service |
---
## Tools
| Script | Purpose |
|--------|---------|
| `vault_config_generator.py` | Generate Vault policy and auth config from application requirements |
| `rotation_planner.py` | Create rotation schedule from a secret inventory file |
| `audit_log_analyzer.py` | Analyze audit logs for anomalies and compliance gaps |

system: "# Secrets Vault Manager\r\n\r\n**Tier:** POWERFUL\r\n**Category:** Engineering\r\n**Domain:** Security / Infrastructure / DevOps\r\n\r\n---\r\n\r\n## Overview\r\n\r\nProduction secret infrastructure management for teams running HashiCorp Vault, cloud-native secret stores, or hybrid architectures. This skill covers policy authoring, auth method configuration, automated rotation, dynamic secrets, audit logging, and incident response.\r\n\r\n**Distinct from env-secrets-manager** which handles local `.env` file hygiene and leak detection. This skill operates at the infrastructure layer — Vault clusters, cloud KMS, certificate authorities, and CI/CD secret injection.\r\n\r\n### When to Use\r\n\r\n- Standing up a new Vault cluster or migrating to a managed secret store\r\n- Designing auth methods for services, CI runners, and human operators\r\n- Implementing automated credential rotation (database, API keys, certificates)\r\n- Auditing secret access patterns for compliance (SOC 2, ISO 27001, HIPAA)\r\n- Responding to a secret leak that requires mass revocation\r\n- Integrating secrets into Kubernetes workloads or CI/CD pipelines\r\n\r\n---\r\n\r\n## HashiCorp Vault Patterns\r\n\r\n### Architecture Decisions\r\n\r\n| Decision | Recommendation | Rationale |\r\n|----------|---------------|-----------|\r\n| Deployment mode | HA with Raft storage | No external dependency, built-in leader election |\r\n| Auto-unseal | Cloud KMS (AWS KMS / Azure Key Vault / GCP KMS) | Eliminates manual unseal, enables automated restarts |\r\n| Namespaces | One per environment (dev/staging/prod) | Blast-radius isolation, independent policies |\r\n| Audit devices | File + syslog (dual) | Vault refuses requests if all audit devices fail — dual prevents outages |\r\n\r\n### Auth Methods\r\n\r\n**AppRole** — Machine-to-machine authentication for services and batch jobs.\r\n\r\n```hcl\r\n# Enable AppRole\r\npath \"auth/approle/*\" {\r\n capabilities = [\"create\", \"read\", \"update\", \"delete\", \"list\"]\r\n}\r\n\r\n# Application-specific role\r\nvault write auth/approle/role/payment-service \\\r\n token_ttl=1h \\\r\n token_max_ttl=4h \\\r\n secret_id_num_uses=1 \\\r\n secret_id_ttl=10m \\\r\n token_policies=\"payment-service-read\"\r\n```\r\n\r\n**Kubernetes** — Pod-native authentication via service account tokens.\r\n\r\n```hcl\r\nvault write auth/kubernetes/role/api-server \\\r\n bound_service_account_names=api-server \\\r\n bound_service_account_namespaces=production \\\r\n policies=api-server-secrets \\\r\n ttl=1h\r\n```\r\n\r\n**OIDC** — Human operator access via SSO provider (Okta, Azure AD, Google Workspace).\r\n\r\n```hcl\r\nvault write auth/oidc/role/engineering \\\r\n bound_audiences=\"vault\" \\\r\n allowed_redirect_uris=\"https://vault.example.com/ui/vault/auth/oidc/oidc/callback\" \\\r\n user_claim=\"email\" \\\r\n oidc_scopes=\"openid,profile,email\" \\\r\n policies=\"engineering-read\" \\\r\n ttl=8h\r\n```\r\n\r\n### Secret Engines\r\n\r\n| Engine | Use Case | TTL Strategy |\r\n|--------|----------|-------------|\r\n| KV v2 | Static secrets (API keys, config) | Versioned, manual rotation |\r\n| Database | Dynamic DB credentials | 1h default, 24h max |\r\n| PKI | TLS certificates | 90d leaf certs, 5y intermediate CA |\r\n| Transit | Encryption-as-a-service | Key rotation every 90d |\r\n| SSH | Signed SSH certificates | 30m for interactive, 8h for automation |\r\n\r\n### Policy Design\r\n\r\nFollow least-privilege with path-based granularity:\r\n\r\n```hcl\r\n# payment-service-read policy\r\npath \"secret/data/production/payment/*\" {\r\n capabilities = [\"read\"]\r\n}\r\n\r\npath \"database/creds/payment-readonly\" {\r\n capabilities = [\"read\"]\r\n}\r\n\r\n# Deny access to admin paths explicitly\r\npath \"sys/*\" {\r\n capabilities = [\"deny\"]\r\n}\r\n```\r\n\r\n**Policy naming convention:** `{service}-{access-level}` (e.g., `payment-service-read`, `api-gateway-admin`).\r\n\r\n---\r\n\r\n## Cloud Secret Store Integration\r\n\r\n### Comparison Matrix\r\n\r\n| Feature | AWS Secrets Manager | Azure Key Vault | GCP Secret Manager |\r\n|---------|--------------------|-----------------|--------------------|\r\n| Rotation | Built-in Lambda | Custom logic via Functions | Cloud Functions |\r\n| Versioning | Automatic | Manual or automatic | Automatic |\r\n| Encryption | AWS KMS (default or CMK) | HSM-backed | Google-managed or CMEK |\r\n| Access control | IAM policies + resource policy | RBAC + Access Policies | IAM bindings |\r\n| Cross-region | Replication supported | Geo-redundant by default | Replication supported |\r\n| Audit | CloudTrail | Azure Monitor + Diagnostic Logs | Cloud Audit Logs |\r\n| Pricing model | Per-secret + per-API call | Per-operation + per-key | Per-secret version + per-access |\r\n\r\n### When to Use Which\r\n\r\n- **AWS Secrets Manager**: RDS/Aurora credential rotation out of the box. Best when fully on AWS.\r\n- **Azure Key Vault**: Certificate management strength. Required for Azure AD integrated workloads.\r\n- **GCP Secret Manager**: Simplest API surface. Best for GKE-native workloads with Workload Identity.\r\n- **HashiCorp Vault**: Multi-cloud, dynamic secrets, PKI, transit encryption. Best for complex or hybrid environments.\r\n\r\n### SDK Access Patterns\r\n\r\n**Principle:** Always fetch secrets at startup or via sidecar — never bake into images or config files.\r\n\r\n```python\r\n# AWS Secrets Manager pattern\r\nimport boto3, json\r\n\r\ndef get_secret(secret_name, region=\"us-east-1\"):\r\n client = boto3.client(\"secretsmanager\", region_name=region)\r\n response = client.get_secret_value(SecretId=secret_name)\r\n return json.loads(response[\"SecretString\"])\r\n```\r\n\r\n```python\r\n# GCP Secret Manager pattern\r\nfrom google.cloud import secretmanager\r\n\r\ndef get_secret(project_id, secret_id, version=\"latest\"):\r\n client = secretmanager.SecretManagerServiceClient()\r\n name = f\"projects/{project_id}/secrets/{secret_id}/versions/{version}\"\r\n response = client.access_secret_version(request={\"name\": name})\r\n return response.payload.data.decode(\"UTF-8\")\r\n```\r\n\r\n```python\r\n# Azure Key Vault pattern\r\nfrom azure.identity import DefaultAzureCredential\r\nfrom azure.keyvault.secrets import SecretClient\r\n\r\ndef get_secret(vault_url, secret_name):\r\n credential = DefaultAzureCredential()\r\n client = SecretClient(vault_url=vault_url, credential=credential)\r\n return client.get_secret(secret_name).value\r\n```\r\n\r\n---\r\n\r\n## Secret Rotation Workflows\r\n\r\n### Rotation Strategy by Secret Type\r\n\r\n| Secret Type | Rotation Frequency | Method | Downtime Risk |\r\n|-------------|-------------------|--------|---------------|\r\n| Database passwords | 30 days | Dual-account swap | Zero (A/B rotation) |\r\n| API keys | 90 days | Generate new, deprecate old | Zero (overlap window) |\r\n| TLS certificates | 60 days before expiry | ACME or Vault PKI | Zero (graceful reload) |\r\n| SSH keys | 90 days | Vault-signed certificates | Zero (CA-based) |\r\n| Service tokens | 24 hours | Dynamic generation | Zero (short-lived) |\r\n| Encryption keys | 90 days | Key versioning (rewrap) | Zero (version coexistence) |\r\n\r\n### Database Credential Rotation (Dual-Account)\r\n\r\n1. Two database accounts exist: `app_user_a` and `app_user_b`\r\n2. Application currently uses `app_user_a`\r\n3. Rotation rotates `app_user_b` password, updates secret store\r\n4. Application switches to `app_user_b` on next credential fetch\r\n5. After grace period, `app_user_a` password is rotated\r\n6. Cycle repeats\r\n\r\n### API Key Rotation (Overlap Window)\r\n\r\n1. Generate new API key with provider\r\n2. Store new key in secret store as `current`, move old to `previous`\r\n3. Deploy applications — they read `current`\r\n4. After all instances restarted (or TTL expired), revoke `previous`\r\n5. Monitoring confirms zero usage of old key before revocation\r\n\r\n---\r\n\r\n## Dynamic Secrets\r\n\r\nDynamic secrets are generated on-demand with automatic expiration. Prefer dynamic secrets over static credentials wherever possible.\r\n\r\n### Database Dynamic Credentials (Vault)\r\n\r\n```hcl\r\n# Configure database engine\r\nvault write database/config/postgres \\\r\n plugin_name=postgresql-database-plugin \\\r\n connection_url=\"postgresql://{{username}}:{{password}}@db.example.com:5432/app\" \\\r\n allowed_roles=\"app-readonly,app-readwrite\" \\\r\n username=\"vault_admin\" \\\r\n password=\"<admin-password>\"\r\n\r\n# Create role with TTL\r\nvault write database/roles/app-readonly \\\r\n db_name=postgres \\\r\n creation_statements=\"CREATE ROLE \\\"{{name}}\\\" WITH LOGIN PASSWORD '{{password}}' VALID UNTIL '{{expiration}}'; GRANT SELECT ON ALL TABLES IN SCHEMA public TO \\\"{{name}}\\\";\" \\\r\n default_ttl=1h \\\r\n max_ttl=24h\r\n```\r\n\r\n### Cloud IAM Dynamic Credentials\r\n\r\nVault can generate short-lived AWS IAM credentials, Azure service principal passwords, or GCP service account keys — eliminating long-lived cloud credentials entirely.\r\n\r\n### SSH Certificate Authority\r\n\r\nReplace SSH key distribution with a Vault-signed certificate model:\r\n\r\n1. Vault acts as SSH CA\r\n2. Users/machines request signed certificates with short TTL (30 min)\r\n3. SSH servers trust the CA public key — no `authorized_keys` management\r\n4. Certificates expire automatically — no revocation needed for normal operations\r\n\r\n---\r\n\r\n## Audit Logging\r\n\r\n### What to Log\r\n\r\n| Event | Priority | Retention |\r\n|-------|----------|-----------|\r\n| Secret read access | HIGH | 1 year minimum |\r\n| Secret creation/update | HIGH | 1 year minimum |\r\n| Auth method login | MEDIUM | 90 days |\r\n| Policy changes | CRITICAL | 2 years (compliance) |\r\n| Failed access attempts | CRITICAL | 1 year |\r\n| Token creation/revocation | MEDIUM | 90 days |\r\n| Seal/unseal operations | CRITICAL | Indefinite |\r\n\r\n### Anomaly Detection Signals\r\n\r\n- Secret accessed from new IP/CIDR range\r\n- Access volume spike (>3x baseline for a path)\r\n- Off-hours access for human auth methods\r\n- Service accessing secrets outside its policy scope (denied requests)\r\n- Multiple failed auth attempts from single source\r\n- Token created with unusually long TTL\r\n\r\n### Compliance Reporting\r\n\r\nGenerate periodic reports covering:\r\n\r\n1. **Access inventory** — Which identities accessed which secrets, when\r\n2. **Rotation compliance** — Secrets overdue for rotation\r\n3. **Policy drift** — Policies modified since last review\r\n4. **Orphaned secrets** — Secrets with no recent access (>90 days)\r\n\r\nUse `audit_log_analyzer.py` to parse Vault or cloud audit logs for these signals.\r\n\r\n---\r\n\r\n## Emergency Procedures\r\n\r\n### Secret Leak Response (Immediate)\r\n\r\n**Time target: Contain within 15 minutes of detection.**\r\n\r\n1. **Identify scope** — Which secret(s) leaked, where (repo, log, error message, third party)\r\n2. **Revoke immediately** — Rotate the compromised credential at the source (provider API, Vault, cloud SM)\r\n3. **Invalidate tokens** — Revoke all Vault tokens that accessed the leaked secret\r\n4. **Audit blast radius** — Query audit logs for usage of the compromised secret in the exposure window\r\n5. **Notify stakeholders** — Security team, affected service owners, compliance (if PII/regulated data)\r\n6. **Post-mortem** — Document root cause, update controls to prevent recurrence\r\n\r\n### Vault Seal Operations\r\n\r\n**When to seal:** Active security incident affecting Vault infrastructure, suspected key compromise.\r\n\r\n**Sealing** stops all Vault operations. Use only as last resort.\r\n\r\n**Unseal procedure:**\r\n1. Gather quorum of unseal key holders (Shamir threshold)\r\n2. Or confirm auto-unseal KMS key is accessible\r\n3. Unseal via `vault operator unseal` or restart with auto-unseal\r\n4. Verify audit devices reconnected\r\n5. Check active leases and token validity\r\n\r\nSee `references/emergency_procedures.md` for complete playbooks.\r\n\r\n---\r\n\r\n## CI/CD Integration\r\n\r\n### Vault Agent Sidecar (Kubernetes)\r\n\r\nVault Agent runs alongside application pods, handles authentication and secret rendering:\r\n\r\n```yaml\r\n# Pod annotation for Vault Agent Injector\r\nannotations:\r\n vault.hashicorp.com/agent-inject: \"true\"\r\n vault.hashicorp.com/role: \"api-server\"\r\n vault.hashicorp.com/agent-inject-secret-db: \"database/creds/app-readonly\"\r\n vault.hashicorp.com/agent-inject-template-db: |\r\n {{- with secret \"database/creds/app-readonly\" -}}\r\n postgresql://{{ .Data.username }}:{{ .Data.password }}@db:5432/app\r\n {{- end }}\r\n```\r\n\r\n### External Secrets Operator (Kubernetes)\r\n\r\nFor teams preferring declarative GitOps over agent sidecars:\r\n\r\n```yaml\r\napiVersion: external-secrets.io/v1beta1\r\nkind: ExternalSecret\r\nmetadata:\r\n name: api-credentials\r\nspec:\r\n refreshInterval: 1h\r\n secretStoreRef:\r\n name: vault-backend\r\n kind: ClusterSecretStore\r\n target:\r\n name: api-credentials\r\n data:\r\n - secretKey: api-key\r\n remoteRef:\r\n key: secret/data/production/api\r\n property: key\r\n```\r\n\r\n### GitHub Actions OIDC\r\n\r\nEliminate long-lived secrets in CI by using OIDC federation:\r\n\r\n```yaml\r\n- name: Authenticate to Vault\r\n uses: hashicorp/vault-action@v2\r\n with:\r\n url: https://vault.example.com\r\n method: jwt\r\n role: github-ci\r\n jwtGithubAudience: https://vault.example.com\r\n secrets: |\r\n secret/data/ci/deploy api_key | DEPLOY_API_KEY ;\r\n secret/data/ci/deploy db_password | DB_PASSWORD\r\n```\r\n\r\n---\r\n\r\n## Anti-Patterns\r\n\r\n| Anti-Pattern | Risk | Correct Approach |\r\n|-------------|------|-----------------|\r\n| Hardcoded secrets in source code | Leak via repo, logs, error output | Fetch from secret store at runtime |\r\n| Long-lived static tokens (>30 days) | Stale credentials, no accountability | Dynamic secrets or short TTL + rotation |\r\n| Shared service accounts | No audit trail per consumer | Per-service identity with unique credentials |\r\n| No rotation policy | Compromised creds persist indefinitely | Automated rotation on schedule |\r\n| Secrets in environment variables on CI | Visible in build logs, process table | Vault Agent or OIDC-based injection |\r\n| Single unseal key holder | Bus factor of 1, recovery blocked | Shamir split (3-of-5) or auto-unseal |\r\n| No audit device configured | Zero visibility into access | Dual audit devices (file + syslog) |\r\n| Wildcard policies (`path \"*\"`) | Over-permissioned, violates least privilege | Explicit path-based policies per service |\r\n\r\n---\r\n\r\n## Tools\r\n\r\n| Script | Purpose |\r\n|--------|---------|\r\n| `vault_config_generator.py` | Generate Vault policy and auth config from application requirements |\r\n| `rotation_planner.py` | Create rotation schedule from a secret inventory file |\r\n| `audit_log_analyzer.py` | Analyze audit logs for anomalies and compliance gaps |\r\n\r\n---\r\n\r\n## Cross-References\r\n\r\n- **env-secrets-manager** — Local `.env` file hygiene, leak detection, drift awareness\r\n- **senior-secops** — Security operations, incident response, threat modeling\r\n- **ci-cd-pipeline-builder** — Pipeline design where secrets are consumed\r\n- **docker-development** — Container secret injection patterns\r\n- **helm-chart-builder** — Kubernetes secret management in Helm charts"
