Defense in depth Don't rely on a single line of

Traceability & Management
Where are our secrets?
Who can access them?
When are they accessed?
How do we rotate them?
We want those answers BEFORE we need them
The right tool SCM? Configuration management? Secrets management tool
Lots of secrets management tools nowadays Keywhiz (Square) Confidant (Lyft)
KMS (Amazon) Docker Secret
Open Source Multiple storage backends Standalone microservice API & CLI
High availability Encryption-as-a-Service Multiple types of secrets Audit friendly Authentication & Authorization
Demo
$ vault write secret/srvA/credentials pwd=azerty Success! Data written to: secret/srvA/credentials
$ vault read secret/srvA/credentials Key Value --- ----- refresh_interval 768h0m0s
pwd azerty
$ vault read /sys/policy/my-service-A path "secret/srvA/*" { capabilities = ["read"]
}
$ curl https://vault01/v1/secret/srvA/credentials -H 'X-Vault-Token:…' { "request_id": "f9e9b545-c624-ebbb-1dbd- d35e1074a478",
"lease_id": "", "renewable": false, "lease_duration": 2764800, "data": { "pwd": "azerty" …
Protecting secrets Turtles all the way down
Secrets are encrypted at rest How does Vault protect secrets?
Encryption keys only live in memory How does Vault protect
secrets?
How to obtain the Master Key? How does Vault protect
secrets?
Master key split in N shards K shards required Vault
sealed until a quorum is reached Shamir secret sharing
How do apps access secrets? Ask Vault at runtime Need
an authentication token How to pass the token to the app?

Vault @ Oodrive
Vault @ Oodrive One service in staging ZooKeeper as storage
backend "Good enough" introduction
Challenges @ Oodrive Ongoing transition to an orchestrated architecture
Challenges @ Oodrive For now: Puppet. No scheduler.
Challenges @ Oodrive Don't want to break everything twice
Challenges @ Oodrive Puppet Server and init script as "scheduler"
Challenges @ Oodrive Leverage existing Puppet authentication
VaultClient client = new Builder(vaultUri) .withTokenAuth(token) .build(); Credentials cred =
client.readSecret( "secret/my-service/db-credentials", Credentials.class); Vanilla Java Client
@SecretPath("credentials") Secret<Credentials> credentialsSecret; … Credentials cred = credentialsSecret.getValue(); Spring
Hopefully to be open sourced
Best practices
Least Privilege all the way!
Vault as single secrets repository
Secrets grouped under service name
Use roles for easier management
Enable ACL on ZooKeeper
Next steps Fully secure introduction Dynamic secrets (db credentials) Vault
as internal PKI
