limit_check(context, resources, values, project_id=None)

Check simple quota limits.

For limits–those quotas for which there is no usage synchronization function–this method checks that a set of proposed values are permitted by the limit restriction.

This method will raise a QuotaResourceUnknown exception if a given resource is unknown or if it is not a simple limit resource.

If any of the proposed values is over the defined quota, an OverQuota exception will be raised with the sorted list of the resources which are too high. Otherwise, the method returns nothing.

reserve(context, resources, deltas, expire=None, project_id=None)

Check quotas and reserve resources.

For counting quotas–those quotas for which there is a usage synchronization function–this method checks quotas against current usage and the desired deltas.

This method will raise a QuotaResourceUnknown exception if a given resource is unknown or if it does not have a usage synchronization function.

If any of the proposed values is over the defined quota, an OverQuota exception will be raised with the sorted list of the resources which are too high. Otherwise, the method returns a list of reservation UUIDs which were created.

Parameters:

context – The request context, for access checks.
resources – A dictionary of the registered resources.
deltas – A dictionary of the proposed delta changes.

A datetime.datetime object will be interpreted as the absolute expiration time. If None is specified, the default expiration time set by –default-reservation-expire will be used (this value will be treated as a number of seconds).
project_id – Specify the project_id if current context is admin and admin wants to impact on common user’s tenant.

usages – If True, the current in_use, reserved and allocated counts will also be returned.

limit_check(context, project_id=None, **values)

Check simple quota limits.

For limits–those quotas for which there is no usage synchronization function–this method checks that a set of proposed values are permitted by the limit restriction.

For counting quotas–those quotas for which there is a usage synchronization function–this method checks quotas against current usage and the desired deltas. The deltas are given as keyword arguments, and current usage and other reservations are factored into the quota check.

This method will raise a QuotaResourceUnknown exception if a given resource is unknown or if it does not have a usage synchronization function.

If any of the proposed values is over the defined quota, an OverQuota exception will be raised with the sorted list of the resources which are too high. Otherwise, the method returns a list of reservation UUIDs which were created.

Parameters:

context – The request context, for access checks.
expire – An optional parameter specifying an expiration time for the reservations. If it is a simple number, it is interpreted as a number of seconds and added to the current time; if it is a datetime.timedelta object, it will also be added to the current time. A datetime.datetime object will be interpreted as the absolute expiration time. If None is specified, the default expiration time set by –default-reservation-expire will be used (this value will be treated as a number of seconds).

Legacy Docs¶

Cinder provides RBAC (Role-based access control) of the AWS-type APIs. We define the following roles:

Roles-Based Access Control of AWS-style APIs using SAML Assertions “Achieving FIPS 199 Moderate certification of a hybrid cloud environment using CloudAudit and declarative C.I.A. classifications”

Introduction¶

We will investigate one method for integrating an AWS-style API with US eAuthentication-compatible federated authentication systems, to achieve access controls and limits based on traditional operational roles. Additionally, we will look at how combining this approach, with an implementation of the CloudAudit APIs, will allow us to achieve a certification under FIPS 199 Moderate classification for a hybrid cloud environment.

Relationship of US eAuth to RBAC¶

Typical implementations of US eAuth authentication systems are structured as follows:

[ MS Active Directory or other federated LDAP user store ]
      --> backends to…
[ SUN Identity Manager or other SAML Policy Controller ]
      --> maps URLs to groups…
[ Apache Policy Agent in front of eAuth-secured Web Application ]

In more ideal implementations, the remainder of the application-specific account information is stored either in extended schema on the LDAP server itself, via the use of a translucent LDAP proxy, or in an independent datastore keyed off of the UID provided via SAML assertion.

Roles¶

AWS API calls are traditionally secured via Access and Secret Keys, which are used to sign API calls, along with traditional timestamps to prevent replay attacks. The APIs can be logically grouped into sets that align with five typical roles:

Base User
System Administrator/Developer (currently have the same permissions)
Network Administrator
Project Manager
Cloud Administrator/IT-Security (currently have the same permissions)

There is an additional, conceptual end-user that may or may not have API access:

(EXTERNAL) End-user / Third-party User

Basic operations are available to any :

Describe Instances
Describe Images
Describe Volumes
Describe Keypairs
Create Keypair
Delete Keypair
Create, Upload, Delete: Buckets and Keys (Object Store)

System Administrators/Developers/Project Manager:

Create, Attach, Delete Volume (Block Store)
Launch, Reboot, Terminate Instance
Register/Unregister Machine Image (project-wide)
Request / Review CloudAudit Scans

Project Manager:

Add and remove other users (currently no api)
Set roles (currently no api)

Network Administrator:

Change Machine Image properties (public / private)
Change Firewall Rules, define Security Groups
Allocate, Associate, Deassociate Public IP addresses

Cloud Administrator/IT-Security:

All permissions

Enhancements¶

SAML Token passing
REST interfaces
SOAP interfaces

Wrapping the SAML token into the API calls. Then store the UID (fetched via backchannel) into the instance metadata, providing end-to-end auditability of ownership and responsibility, without PII.

CloudAudit APIs¶

Request formats
Response formats
Stateless asynchronous queries

CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates. RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability.

Type declarations¶

Data declarations – Volumes and Objects
System declarations – Instances

Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:

RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low

These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’. (C.I.A. classifications on a bucket would be inherited by the keys within this bucket.)

Request Brokering¶

Cloud Interop
IMF Registration / PubSub
Digital C&A

Establishing declarative semantics for individual API calls will allow the cloud environment to seamlessly proxy these API calls to external, third-party vendors – when the requested CIA levels match.

See related work within the Infrastructure 2.0 working group for more information on how the IMF Metadata specification could be utilized to manage registration of these vendors and their C&A credentials.

Dirty Cloud - Hybrid Data Centers¶

CloudAudit bridge interfaces
Anything in the ARP table

A hybrid cloud environment provides dedicated, potentially co-located physical hardware with a network interconnect to the project or users’ cloud virtual network.

This interconnect is typically a bridged VPN connection. Any machines that can be bridged into a hybrid environment in this fashion (at Layer 2) must implement a minimum version of the CloudAudit spec, such that they can be queried to provide a complete picture of the IT-sec runtime environment.

Network discovery protocols (ARP, CDP) can be applied in this case, and existing protocols (SNMP location data, DNS LOC records) overloaded to provide CloudAudit information.

The Details¶

Preliminary Roles Definitions
Categorization of available API calls
SAML assertion vocabulary

System limits¶

The following limits need to be defined and enforced:

Total number of instances allowed (user / project)
Total number of instances, per instance type (user / project)
Total number of volumes (user / project)
Maximum size of volume
Cumulative size of all volumes
Total use of object storage (GB)
Total number of Public IPs

Further Challenges¶

Prioritization of users / jobs in shared computing environments
Incident response planning
Limit launch of instances to specific security groups based on AMI
Store AMIs in LDAP for added property control
