(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|

within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.

||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|

||||
## All the languages supported by Casbin:
|
||||
|
||||
- Golang: [Casbin](https://github.com/casbin/casbin) (production-ready)
|
||||
- Java: [jCasbin](https://github.com/casbin/jcasbin) (production-ready)
|
||||
- PHP: [PHP-Casbin](https://github.com/sstutz/php-casbin) (experimental)
|
||||
- Node.js: [node-casbin](https://github.com/casbin/node-casbin) (WIP)

## Supported models
|
||||
|
||||
1. [**ACL (Access Control List)**](https://en.wikipedia.org/wiki/Access_control_list)
|
||||
2. **ACL with [superuser](https://en.wikipedia.org/wiki/Superuser)**
|
||||
3. **ACL without users**: especially useful for systems that don't have authentication or user log-ins.
|
||||
3. **ACL without resources**: some scenarios may target for a type of resources instead of an individual resource by using permissions like ``write-article``, ``read-log``. It doesn't control the access to a specific article or log.
|
||||
4. **[RBAC (Role-Based Access Control)](https://en.wikipedia.org/wiki/Role-based_access_control)**
|
||||
5. **RBAC with resource roles**: both users and resources can have roles (or groups) at the same time.
|
||||
6. **RBAC with domains/tenants**: users can have different role sets for different domains/tenants.
|
||||
7. **[ABAC (Attribute-Based Access Control)](https://en.wikipedia.org/wiki/Attribute-Based_Access_Control)**: syntax sugar like ``resource.Owner`` can be used to get the attribute for a resource.
|
||||
8. **[RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer)**: supports paths like ``/res/*``, ``/res/:id`` and HTTP methods like ``GET``, ``POST``, ``PUT``, ``DELETE``.
|
||||
9. **Deny-override**: both allow and deny authorizations are supported, deny overrides the allow.
|
||||
10. **Priority**: the policy rules can be prioritized like firewall rules.
|
||||
|
||||
## How it works?
|
||||
|
||||
In Casbin, an access control model is abstracted into a CONF file based on the **PERM metamodel (Policy, Effect, Request, Matchers)**. So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. You can customize your own access control model by combining the available models. For example, you can get RBAC roles and ABAC attributes together inside one model and share one set of policy rules.
|
||||
|
||||
The most basic and simplest model in Casbin is ACL. ACL's model CONF is:
|
||||
|
||||
```ini
|
||||
# Request definition
|
||||
[request_definition]
|
||||
r = sub, obj, act
|
||||
|
||||
# Policy definition
|
||||
[policy_definition]
|
||||
p = sub, obj, act
|
||||
|
||||
# Policy effect
|
||||
[policy_effect]
|
||||
e = some(where (p.eft == allow))
|
||||
|
||||
# Matchers
|
||||
[matchers]
|
||||
m = r.sub == p.sub && r.obj == p.obj && r.act == p.act
|
||||
|
||||
# We also support multi-line mode by appending '\' in the end:
|
||||
# m = r.sub == p.sub && r.obj == p.obj \
|
||||
# && r.act == p.act
|
||||
```
|
||||
|
||||
An example policy for ACL model is like:
|
||||
|
||||
```
|
||||
p, alice, data1, read
|
||||
p, bob, data2, write
|
||||
```
|
||||
|
||||
It means:
|
||||
|
||||
- alice can read data1
|
||||
- bob can write data2
|
||||
|
||||
## Features
|
||||
|
||||
What Casbin does:
|
||||
|
||||
1. enforce the policy in the classic ``{subject, object, action}`` form or a customized form as you defined, both allow and deny authorizations are supported.
|
||||
2. handle the storage of the access control model and its policy.
|
||||
3. manage the role-user mappings and role-role mappings (aka role hierarchy in RBAC).
|
||||
4. support built-in superuser like ``root`` or ``administrator``. A superuser can do anything without explict permissions.
|
||||
5. multiple built-in operators to support the rule matching. For example, ``keyMatch`` can map a resource key ``/foo/bar`` to the pattern ``/foo*``.
|
||||
|
||||
What Casbin does NOT do:
|
||||
|
||||
1. authentication (aka verify ``username`` and ``password`` when a user logs in)
|
||||
2. manage the list of users or roles. I believe it's more convenient for the project itself to manage these entities. Users usually have their passwords, and Casbin is not designed as a password container. However, Casbin stores the user-role mapping for the RBAC scenario.
|
||||

## Documentation
|
||||
|
||||
For documentation, please see: [Our Wiki](https://github.com/casbin/casbin/wiki)
|
||||
|
||||
## Online editor
|
||||
|
||||
You can also use the online editor (http://casbin.org/editor/) to write your Casbin model and policy in your web browser. It provides functionality such as ``syntax highlighting`` and ``code completion``, just like an IDE for a programming language.

- [Using Casbin with Beego: 4. Policy update (in Chinese)](https://blog.csdn.net/hotqin888/article/details/80032538)
|
||||
|
||||
## Get started
|
||||
|
||||
1. New a Casbin enforcer with a model file and a policy file:
|
||||
|
||||
```go
|
||||
e := casbin.NewEnforcer("path/to/model.conf", "path/to/policy.csv")
|
||||
```
|
||||
|
||||
Note: you can also initialize an enforcer with policy in DB instead of file, see [Persistence](#persistence) section for details.
|
||||
|
||||
2. Add an enforcement hook into your code right before the access happens:
|
||||
|
||||
```go
|
||||
sub := "alice" // the user that wants to access a resource.
|
||||
obj := "data1" // the resource that is going to be accessed.
|
||||
act := "read" // the operation that the user performs on the resource.
|
||||
|
||||
if e.Enforce(sub, obj, act) == true {
|
||||
// permit alice to read data1
|
||||
} else {
|
||||
// deny the request, show an error
|
||||
}
|
||||
```
|
||||
|
||||
3. Besides the static policy file, Casbin also provides API for permission management at run-time. For example, You can get all the roles assigned to a user as below:
|
||||
|
||||
```go
|
||||
roles := e.GetRoles("alice")
|
||||
```
|
||||
|
||||
See [Policy management APIs](#policy-management) for more usage.
|
||||
|
||||
4. Please refer to the ``_test.go`` files for more usage.
|
||||
|
||||
## Policy management
|
||||
|
||||
Casbin provides two sets of APIs to manage permissions:
|
||||

- [Management API](https://github.com/casbin/casbin/blob/master/management_api.go): the primitive API that provides full support for Casbin policy management. See [here](https://github.com/casbin/casbin/blob/master/management_api_test.go) for examples.
|
||||
- [RBAC API](https://github.com/casbin/casbin/blob/master/rbac_api.go): a more friendly API for RBAC. This API is a subset of Management API. The RBAC users could use this API to simplify the code. See [here](https://github.com/casbin/casbin/blob/master/rbac_api_test.go) for examples.

## Policy persistence
|
||||
|
||||
In Casbin, the policy storage is implemented as an adapter (aka middleware for Casbin). To keep light-weight, we don't put adapter code in the main library (except the default file adapter). A complete list of Casbin adapters is provided as below. Any 3rd-party contribution on a new adapter is welcomed, please inform us and I will put it in this list:)

|
||||
|
||||
## Policy enforcement at scale
|
||||
|
||||
Some adapters support filtered policy management. This means that the policy loaded by Casbin is a subset of the policy in storage based on a given filter. This allows for efficient policy enforcement in large, multi-tenant environments when parsing the entire policy becomes a performance bottleneck.
|
||||
|
||||
To use filtered policies with a supported adapter, simply call the `LoadFilteredPolicy` method. The valid format for the filter parameter depends on the adapter used. To prevent accidental data loss, the `SavePolicy` method is disabled when a filtered policy is loaded.
|
||||
|
||||
For example, the following code snippet uses the built-in filtered file adapter and the RBAC model with domains. In this case, the filter limits the policy to a single domain. Any policy lines for domains other than `"domain1"` are omitted from the loaded policy:
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/casbin/casbin"
|
||||
)
|
||||
|
||||
enforcer := casbin.NewEnforcer()
|
||||
|
||||
adapter := fileadapter.NewFilteredAdapter("examples/rbac_with_domains_policy.csv")
|
||||
enforcer.InitWithAdapter("examples/rbac_with_domains_model.conf", adapter)
|
||||
|
||||
filter := &fileadapter.Filter{
|
||||
P: []string{"", "domain1"},
|
||||
G: []string{"", "", "domain1"},
|
||||
}
|
||||
enforcer.LoadFilteredPolicy(filter)
|
||||
|
||||
// The loaded policy now only contains the entries pertaining to "domain1".
|
||||
```
|
||||
|
||||
## Policy consistence between multiple nodes
|
||||
|
||||
We support to use distributed messaging systems like [etcd](https://github.com/coreos/etcd) to keep consistence between multiple Casbin enforcer instances. So our users can concurrently use multiple Casbin enforcers to handle large number of permission checking requests.
|
||||
|
||||
Similar to policy storage adapters, we don't put watcher code in the main library. Any support for a new messaging system should be implemented as a watcher. A complete list of Casbin watchers is provided as below. Any 3rd-party contribution on a new watcher is welcomed, please inform us and I will put it in this list:)
|
||||
|
||||
Watcher | Type | Author | Description
|
||||
----|------|----|----
|
||||
[Etcd Watcher](https://github.com/casbin/etcd-watcher) | KV store | Casbin | Watcher for [etcd](https://github.com/coreos/etcd)
|
||||
[NATS Watcher](https://github.com/Soluto/casbin-nats-watcher) | Messaging system | [Soluto](https://github.com/Soluto) | Watcher for [NATS](https://nats.io/)
|
||||
[ZooKeeper Watcher](https://github.com/grepsr/casbin-zk-watcher) | KV store | [Grepsr](https://github.com/grepsr) | Watcher for [Apache ZooKeeper](https://zookeeper.apache.org/)

|

|
||||
## Role manager
|
||||
|
||||
The role manager is used to manage the RBAC role hierarchy (user-role mapping) in Casbin. A role manager can retrieve the role data from Casbin policy rules or external sources such as LDAP, Okta, Auth0, Azure AD, etc. We support different implementations of a role manager. To keep light-weight, we don't put role manager code in the main library (except the default role manager). A complete list of Casbin role managers is provided as below. Any 3rd-party contribution on a new role manager is welcomed, please inform us and I will put it in this list:)
|
||||
|
||||
Role manager | Author | Description
|
||||
----|----|----
|
||||
[Default Role Manager (built-in)](https://github.com/casbin/casbin/blob/master/rbac/default-role-manager/role_manager.go) | Casbin | Supports role hierarchy stored in Casbin policy
|
||||
[Session Role Manager](https://github.com/casbin/session-role-manager) | [EDOMO Systems](https://github.com/edomosystems) | Supports role hierarchy stored in Casbin policy, with time-range-based sessions
|
||||
[Okta Role Manager](https://github.com/casbin/okta-role-manager) | Casbin | Supports role hierarchy stored in [Okta](https://www.okta.com/)
|
||||
[Auth0 Role Manager](https://github.com/casbin/auth0-role-manager) | Casbin | Supports role hierarchy stored in [Auth0](https://auth0.com/)'s [Authorization Extension](https://auth0.com/docs/extensions/authorization-extension/v2)
|
||||
|
||||
For developers: all role managers must implement the [RoleManager](https://github.com/casbin/casbin/blob/master/rbac/role_manager.go) interface. [Session Role Manager](https://github.com/casbin/session-role-manager) can be used as a reference implementation.
|
||||
|
||||
## Multi-threading
|
||||
|
||||
If you use Casbin in a multi-threading manner, you can use the synchronized wrapper of the Casbin enforcer: https://github.com/casbin/casbin/blob/master/enforcer_synced.go.
|
||||
|
||||
It also supports the ``AutoLoad`` feature, which means the Casbin enforcer will automatically load the latest policy rules from DB if it has changed. Call ``StartAutoLoadPolicy()`` to start automatically loading policy periodically and call ``StopAutoLoadPolicy()`` to stop it.
|
||||
|
||||
## Benchmarks
|
||||
|
||||
The overhead of policy enforcement is benchmarked in [model_b_test.go](https://github.com/casbin/casbin/blob/master/model_b_test.go). The testbed is:
|
||||
|
||||
```
|
||||
Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2601 Mhz, 4 Core(s), 8 Logical Processor(s)
|
||||
```
|
||||
|
||||
The benchmarking result of ``go test -bench=. -benchmem`` is as follows (op = an ``Enforce()`` call, ms = millisecond, KB = kilo bytes):
|
||||
|
||||
Test case | Size | Time overhead | Memory overhead
|
||||
----|------|------|----
|
||||
ACL | 2 rules (2 users) | 0.015493 ms/op | 5.649 KB
|
||||
RBAC | 5 rules (2 users, 1 role) | 0.021738 ms/op | 7.522 KB
|
||||
RBAC (small) | 1100 rules (1000 users, 100 roles) | 0.164309 ms/op | 80.620 KB
|
||||
RBAC (medium) | 11000 rules (10000 users, 1000 roles) | 2.258262 ms/op | 765.152 KB
|
||||
RBAC (large) | 110000 rules (100000 users, 10000 roles) | 23.916776 ms/op | 7.606 MB
|
||||
RBAC with resource roles | 6 rules (2 users, 2 roles) | 0.021146 ms/op | 7.906 KB
|
||||
RBAC with domains/tenants | 6 rules (2 users, 1 role, 2 domains) | 0.032696 ms/op | 10.755 KB
|
||||
ABAC | 0 rule (0 user) | 0.007510 ms/op | 2.328 KB
|
||||
RESTful | 5 rules (3 users) | 0.045398 ms/op | 91.774 KB
|
||||
Deny-override | 6 rules (2 users, 1 role) | 0.023281 ms/op | 8.370 KB
|
||||
Priority | 9 rules (2 users, 2 roles) | 0.016389 ms/op | 5.313 KB
