How do we secure all the things?

#NABShow
Cloud Platform resource hierarchy

#NABShow
Projects and access
Granting access Manage your organization's identities with G Suite.
Implement Google Cloud Directory Sync.
gcloud SDK,
Compute Engine API
Authentication is performed by the SDK itself.
Credentials are picked up by the API client libraries.
Automating
security checks
Implement Forseti Security to run periodic checks
for policy compliance.

Encryption key management
Cloud storage All data is encrypted at rest using either AES128 or AES256 encryption.
Data is always encrypted before it's written to disk.
Cloud KMS Store encryption keys centrally in the cloud, for use by cloud services.
Let Google manage your keys, or manage keys yourself.

Network security
Networks and
subnetworks
Isolate resources on separate networks to add an extra level of security.
Subnetworks are created automatically, one for each compute zone.
Firewall rules Rules apply to the entire network.
To allow incoming traffic, you must create 'allow' firewall rules.
External IP
addresses
Ability to disable the assignment of an external IP on instance creation.
The instance will then only be visible over VPN, or from within the network.

Disk images
Public Compute Engine offers many preconfigured public images.
Each OS image has been configured to work closely with
Google Cloud Platform services and resources.
Custom Use your own custom image, but ensure you comply with
security best practices.

Connectivity
Google Cloud
VPN
Regardless of how you're connected to Google, you must
secure your connection with a Virtual Private Network (VPN).
Direct peering Connect directly to a Google PoP. This is typically the fastest option.

File systems
Object-based Encrypted, localized, available worldwide.
Pipeline implications, however.
POSIX-compliant Known as Persistent Disk (PD) on GCP.
The security features of object-based storage, available as an NFS server.
Other filesystems Clustered or caching filesystems are also available,
however they are not under the management of IAM or
other Google security mechanisms.

Encryption
Storage security Security features are consistent across storage classes.
By default, Google manages encryption keys.
When is data
encrypted?
Both at rest and in-transit.
If using VPN (which you should), data is encrypted before leaving on-prem.

Transferring data
SDK and API gsutil, gcloud, rsync, ssh can be used, but we recommend
gsutil for anything less than 10Gb in size.
UDP-based Aspera, Tervela Cloud FastPath, BitSpeed Velocity or FDT are all options,
however they're all third-party services and are not managed by Google.

Other considerations
Queue
management
Use the gcloud command to communicate with Google Cloud, rather than via ssh.
Consider running your queue system entirely on Google Cloud Platform.
Custom software There are a number of client libraries available for use by third-party software API.
Each library provides methods for OAuth2.0 authorization.
Licensing Use your own on-prem license server across a VPN.
Running a license server in the cloud.
