# Access policy engine
|
||||
|
||||
## General overview
|
||||
|
||||
### Purpose
|
||||
|
||||
Access policy engine (APE) is aimed at checking if a request can be performed over a resource by looking up the set chains of rules.
|
||||
|
||||
#### Terms
|
||||
|
||||
| Term | Description | Structure overview |
|
||||
| -------------- | -------------------------------------------------------------- | -------------- |
|
||||
| `Request` | The action that is being performed on the `Resource`. | <ul><li>`Operation` - `GetObject`,`PutObject` etc.;</li><li>`Properties` - actor's public key, actor's attributes;</li><li>`Resource`.</li></ul> |
|
||||
| `Resource` | The object that the request is being performed on. Check also [resource.md](./resource.md). | <ul><li>`Name` - strictly formatted string value;</li><li>`Properties`.</li></ul> |
|
||||
| `Chain` | A chain of `Rule`-s defined for a specific target. Chains are strictly distinguished by `Name`-s , i.e. chains with name `ingress` are not intersected with chains with name `s3`. Chains are stored in serialized format. | <ul><li>Base64-encoded `ID`;</li><li>List of `Rule`-s;</li><li>`MatchType` - defines rule status selection priority.</li></ul> |
|
||||
| `Rule` | `Rule` defines which status is returned if `Request` matches all conditions. | <ul><li>`Status`: `Allow`, `AccessDenied`, `QuotaLimitReached`, `NoRuleFound`;</li><li>`Actions` - operation defined by a schema (`GetObject`, `PutContainer` etc.);</li><li>`Resources`;</li><li>`Any` - if `true` then `Reqeust` matches `Rule` if any `Condition` is `true`;</li><li>`Conditions`.</li></ul> |
|
||||
| `Name` | `Name` of a chain (do not confuse with chain ID). `Name` defines a layer of `Chain`'s usage, so chains are distinguished by `Name`-s. Basically, `Name` refers to a protocol. | String value (`ingress`, `s3`, `iam`). |
|
||||
| `Target` | A scope of request. `Target` can be either simple (only namespace; only container; only user; only groups) or compound (namespace + container). | <ul><li>`Namespace`;</li><li>`Container`;</li><li>`User`;</li><li>`Groups`.</li></ul> |
|
||||
| `Engine` | `Engine` checks a request in a scope defined by `Target`. First, it is trying to match a request with rules defined in `LocalOverrideStorage` and, then, in `MorphRuleChainStorage`. | <ul><li>`LocalOverrideStorage` - chains stored in the local override storage have the highest priority</li><li>`MorphRuleChainStorage` - basically, chains stored in `Policy` contract;</li><li>`ChainRouter` - looks up chains and try to match them with `Request`.</li></ul> |
|
||||
|
||||
#### Details
|
||||
|
||||
Here some entities are overviewed in more detail.
|
||||
|
||||
##### Resource
|
||||
|
||||
`Resource`'s name is strictly formatted, the format is defined by a schema (`native`, `aws` etc.). Examples:
|
||||
|
||||
```bash
|
||||
# The resource is the particular object with the address within Root namespace
|
||||
native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
|
||||
# The resource is all objects within the container within Root namespace
|
||||
native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/*
|
||||
# The resource is the particular container within the namespace
|
||||
native:container/namespace1/HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj
|
||||
# The resource is all containers within the namespace
|
||||
native:container/namespace1/*
|
||||
```
|
||||
|
||||
##### Rule
|
||||
|
||||
`Rule` works out if:
|
||||
|
||||
1. a requests's operation matches the rule's `Actions`;
|
||||
2. resource name matches the rule's `Resources`;
|
||||
3. if all (or at least one if `Any=true`) conditions in `Condition` is met. Each condition defines how to retrieve
|
||||
and compare the retrieved value. If `Condition`'s `Object` is set to `Resource` then the value is retrieved from the
|
||||
resource's properties (example: container zone attribute). If `Object` is set to `Request`, the it's retrieved from the request's properties (example: actor's public key).
|
||||
|
||||
###### Name matching
|
||||
|
||||
`Resource`'s name in `Rule` may contain wildcard '*' that can be considered as a regular expression:
|
||||
|
||||
```bash
|
||||
# The resource is all objects within the container within Root namespace
|
||||
native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/*
|
||||
```
|
||||
|
||||
If an incoming request has such a resource name, then names are matched:
|
||||
|
||||
```bash
|
||||
# The resource is all objects within the container within Root namespace
|
||||
native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
|
||||
```
|
||||
|
||||
If the incoming request has such a resource name that specifies a container's object within namespace, for instance, `namespicy`,
|
||||
then matching does not work out:
|
||||
|
||||
```bash
|
||||
# The resource is all objects within the container within `namespicy` namespace:
|
||||
native:object/namespicy/HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
|
||||
```
|
||||
|
||||
##### Engine
|
||||
|
||||
`Engine` is trying to match the request against **the target** looking up chain rules, firstly, in `LocalOverrideStorage` (these rules are also known as *local overrides*) and then in `MorphRuleChainStorage` (contract `Policy`). Both storages iterate chain rules according to the specified priority of the targets: `namespace` -> `container` -> `user` -> `groups`.
|
||||
|
||||
#### Diagrams
|
||||
|
||||
The diagram demonstrates a scenario in Storage node. The request `A` cannot be performed as APE matched
|
||||
the request and returned `Access Denied` status. The request `B` is allowed and the client gets `OK` status.
|
||||
|
||||
|
||||
The diagram demonstrates a complex scenario with S3, IAM and Storage node.

# Policy converters
|
||||
|
||||
This repository contains converters that provide opportunities to
|
||||
transform [AWS IAM policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies.html) to inner
|
||||
FrostFS policy format. This document describes such transformations.
|
||||
|
||||
## FrostFS
|
||||
|
||||
As it was mentioned there are converters that transform AWS IAM policies to FrostFS.
|
||||
Here common examples of AWS:
|
||||
|
||||
```json
|
||||
{
|
||||
"Version": "2012-10-17",
|
||||
"Statement": [
|
||||
{
|
||||
"Effect": "Allow",
|
||||
"Action": [
|
||||
"s3:*"
|
||||
],
|
||||
"Resource": "*"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
and FrostFS:
|
||||
|
||||
```json
|
||||
{
|
||||
"ID": "c29tZS1pZA==",
|
||||
"Rules": [
|
||||
{
|
||||
"Status": "Allow",
|
||||
"Actions": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"s3:*"
|
||||
]
|
||||
},
|
||||
"Resources": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"*"
|
||||
]
|
||||
},
|
||||
"Any": false,
|
||||
"Condition": null
|
||||
}
|
||||
],
|
||||
"MatchType": "DenyPriority"
|
||||
}
|
||||
```
|
||||
|
||||
policies.
|
||||
|
||||
Despite there is only one FrostFS format, we have two converters (`s3` and `native`). The reason is S3 gateway and
|
||||
Storage node have different actions and resource naming:
|
||||
|
||||
* S3 has [a lot of methods](https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations.html) and operates with
|
||||
bucket/object
|
||||
* Storage node has only 6 container and 7 object methods and operates container/object (that has different format)
|
||||
|
||||
The following sections describe each transformation more precisely ([common](#common) sections contains shared concepts)
|
||||
|
||||
### Common
|
||||
|
||||
#### Fields
|
||||
|
||||
Rough json main fields mapping:
|
||||
|
||||
| AWS policy field | FrostFS policy field | Comment |
|
||||
|------------------|----------------------|------------------------------------------------------------------|
|
||||
| `Version` | - | Not applicable |
|
||||
| `Statement` | `Rules` | |
|
||||
| `Effect` | `Status` | |
|
||||
| `Action` | `Actions.Names` | `Actions.Inverted` = false |
|
||||
| `NotAction` | `Actions.Names` | `Actions.Inverted` = true |
|
||||
| `Resource` | `Resources.Names` | `Resources.Inverted` = false |
|
||||
| `NotResource` | `Resources.Names` | `Resources.Inverted` = true |
|
||||
| `Condition` | `Condition` | `Any` = false, that means the conditions must be hold altogether |
|
||||
| `Principal` | - | Expressed via conditions (depends on s3/native converters) |
|
||||
|
||||
### Conditions
|
||||
|
||||
Each condition in FrostFS policy can add requirements to some request/resource properties
|
||||
and consists of the following fields:
|
||||
|
||||
| Field | Description |
|
||||
|----------|-------------------------------------------------------------------------------------------|
|
||||
| `Op` | Condition type operation (`StringEqual`, `NumericEqual` etc) |
|
||||
| `Object` | Property type to which condition can be applied (`Request` property, `Resource` property) |
|
||||
| `Key` | Property key |
|
||||
| `Value` | Property value |
|
||||
|
||||
Conditions operators:
|
||||
|
||||
| AWS conditions operator | FrostFS condition operator | Comment |
|
||||
|-----------------------------|-----------------------------|-------------------------------------------------------------------|
|
||||
| `StringEquals` | `StringEquals` | |

|
||||
| `NumericGreaterThan` | `NumericGreaterThan` | |
|
||||
| `NumericGreaterThanEquals` | `NumericGreaterThanEquals` | |
|
||||
| `DateEquals` | `StringEquals` | Date transforms to unix timestamp to be compared as string |

| `ArnNotLike` | `StringNotLike` | |
|
||||
| `SliceContains` | `SliceContains` | AWS spec doesn't contain such operator. This is FrostFS extension |
|
||||
|
||||
For example, AWS conditions:
|
||||
|
||||
```json
|
||||
{
|
||||
"Condition": {
|
||||
"ArnEquals": {"key16": ["val16"]},
|
||||
"ArnNotEquals": {"key18": ["val18"]},

"Bool": {"key13": ["True"]},
|
||||
"DateEquals": {"key7": ["2006-01-02T15:04:05+07:00"]},
|
||||
"DateGreaterThan": {"key11": ["2006-01-02T15:04:05-01:00"]},
|
||||
"DateGreaterThanEquals": {"key12": ["2006-01-02T15:04:05-03:00"]},
|
||||
"DateLessThan": {"key9": ["2006-01-02T15:04:05+06:00"]},
|
||||
"DateLessThanEquals": {"key10": ["2006-01-02T15:04:05+03:00"]},
|
||||
"DateNotEquals": {"key8": ["2006-01-02T15:04:05Z"]},
|
||||
"NumericEquals": {"key20": ["-20"]},
|
||||
"NumericGreaterThan": {"key24": ["-24.24"]},
|
||||
"NumericGreaterThanEquals": {"key25": ["+25.25"]},
|
||||
"NumericLessThan": {"key22": ["0"]},
|
||||
"NumericLessThanEquals": {"key23": ["23.23"]},
|
||||
"NumericNotEquals": {"key21": ["+21"]},
|
||||
"StringEquals": {"key1": ["val0"]},
|
||||
"StringEqualsIgnoreCase": {"key3": ["val3"]},

|
||||
"StringNotLike": {"key6": ["val6"]}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
transforms to FrostFS conditions:
|
||||
|
||||
```json
|
||||
{
|
||||
"Condition": [
|
||||
{"Op": "StringLike", "Object": "Request", "Key": "key5", "Value": "val5"},
|
||||
{"Op": "StringNotEquals", "Object": "Request", "Key": "key2", "Value": "val2"},

|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### S3
|
||||
|
||||
#### Actions
|
||||
|
||||
Each action allows some s3-gw methods, so we must transform action to specific method names
|
||||
(you can see exact mapping in table in [this file](../iam/converter_s3.go)).
|
||||
|
||||
For example the following actions:
|
||||
|
||||
```json
|
||||
{
|
||||
"Action": [
|
||||
"s3:DeleteObject",
|
||||
"iam:CreateUser"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
transforms to
|
||||
|
||||
```json
|
||||
{
|
||||
"Actions": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"s3:DeleteObject",
|
||||
"s3:DeleteMultipleObjects",
|
||||
"iam:CreateUser"
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
As we can see any `iam:*` action transformed as it is. But `s3:*` actions transforms according to
|
||||
[spec rules](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazons3.html) and s3-gw
|
||||
[method names](https://git.frostfs.info/TrueCloudLab/frostfs-s3-gw/src/commit/2ab655b909c40db6f7a4e41e07d8b99167f791bd/api/middleware/constants.go#L3-L76).
|
||||
|
||||
#### Resources
|
||||
|
||||
Resource is transformed as it is:
|
||||
|
||||
```json
|
||||
{
|
||||
"Resource": [
|
||||
"arn:aws:s3:::bucket/object"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"Resources": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"arn:aws:s3:::bucket/object"
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Principals
|
||||
|
||||
To check user s3-gw uses special condition request property (`Owner`), so when AWS policy contains principal field
|
||||
it transforms to rule with appropriate condition. To get correct `Owner` property value special user resolver
|
||||
(`S3Resolver` interface in [converter_s3 file](../iam/converter_s3.go)) must be provided into convert function.
|
||||
|
||||
For example such AWS json statement:
|
||||
|
||||
```json
|
||||
{
|
||||
"Effect": "Allow",
|
||||
"Action": "*",
|
||||
"Resource": "*",
|
||||
"Principal": {
|
||||
"AWS": "arn:aws:iam::111122223333:user/JohnDoe"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
transforms to the following FrostFS rule:
|
||||
|
||||
```json
|
||||
{
|
||||
"Status": "Allow",
|
||||
"Actions": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"*"
|
||||
]
|
||||
},
|
||||
"Resources": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"*"
|
||||
]
|
||||
},
|
||||
"Any": false,
|
||||
"Condition": [
|
||||
{
|
||||
"Op": "StringEquals",
|
||||
"Object": "Request",
|
||||
"Key": "Owner",
|
||||
"Value": "NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Native
|
||||
|
||||
#### Actions
|
||||
|
||||
Each action allows some frostfs methods, so we must transform action to specific method names
|
||||
(you can see exact mapping in table in [this file](../iam/converter_native.go)).
|
||||
|
||||
For example the following actions:
|
||||
|
||||
```json
|
||||
{
|
||||
"Action": [
|
||||
"s3:DeleteObject",
|
||||
"iam:CreateUser"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
transforms to
|
||||
|
||||
```json
|
||||
{
|
||||
"Actions": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"PutObject",
|
||||
"HeadObject",
|
||||
"GetObject",
|
||||
"RangeObject",
|
||||
"GetContainer",
|
||||
"DeleteObject"
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
> **Note:** Only subset of s3:* actions can be transformed (exact value you can see in mapping table mentioned before).
|
||||
> If all provided actions is not applicable converter function returns appropriate error.
|
||||
|
||||
Native methods (to which original actions are transformed) depend on which methods are invoked by appropriate s3-gw
|
||||
[method](https://git.frostfs.info/TrueCloudLab/frostfs-s3-gw/src/commit/2ab655b909c40db6f7a4e41e07d8b99167f791bd/api/middleware/constants.go#L3-L76).
|
||||
|
||||
So in example above s3-gw during performing DeleteObject methods invokes the following methods:
|
||||
`["PutObject","HeadObject","GetObject","RangeObject","GetContainer","DeleteObject"]`
|
||||
|
||||
#### Resources
|
||||
|
||||
To transform resources the following is being performed:
|
||||
|
||||
* Bucket name is resoled to container id (by providing `NativeResolver` interface implementation to converter)
|
||||
* Object name is transformed to condition with special `FilePath` attribute
|
||||
(that present on every object that was uploaded via s3-gw)
|
||||
|
||||
For example, the following AWS policy statement:
|
||||
|
||||
```json
|
||||
{
|
||||
"Principal": "*",
|
||||
"Effect": "Allow",
|
||||
"Action": "*",
|
||||
"Resource": "arn:aws:s3:::bucket/object"
|
||||
}
|
||||
```
|
||||
|
||||
transforms to FrostFS native policy rule:
|
||||
|
||||
```json
|
||||
{
|
||||
"Status": "Allow",
|
||||
"Actions": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"*"
|
||||
]
|
||||
},
|
||||
"Resources": {
|
||||
"Inverted": false,
|
||||
"Names": [
|
||||
"native:object//bucket/HFq67qbfhFEiEL7qDXqayo3F78yAvxXSXzwSa2hKM9bH/*",
|
||||
"native:container//bucket/HFq67qbfhFEiEL7qDXqayo3F78yAvxXSXzwSa2hKM9bH"
|
||||
]
|
||||
},
|
||||
"Any": false,
|
||||
"Condition": [
|
||||
{
|
||||
"Op": "StringLike",
|
||||
"Object": "Resource",
|
||||
"Key": "FilePath",
|
||||
"Value": "object"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
#### Principals
|
||||
|
||||
To check user s3-gw uses special condition request property (`$Actor:publicKey`), so when AWS policy contains principal
|
||||
field it transforms to rule with appropriate condition. To get correct `$Actor:publicKey` property value
|
||||
special user resolver (`NativeResolver` interface in [converter_native file](../iam/converter_native.go)) must be
|
||||

# Resource
|
||||
|
||||
From the point of the access policy engine, a resource is an object to which a request is being performed.
|
||||
This can be an object in a container within a namespace, or all objects in a container,
|
||||
or all containers within the root namespace etc.
|
||||
|
||||
A resource can be viewed from two sides:
|
||||
- As part of a [request](../pkg/resource/resource.go). In this case a resource has a name and properties.
|
||||
- As part of rule [chain](../pkg/chain/chain.go): a resource has just a name.
|
||||
|
||||
## Resource name
|
||||
|
||||
A resource name must have a such format that can be processed by a chain router that matches a request
|
||||
either with local overrides or with rules within policy contract to get if this request is allowed to be performed.
|
||||
The main idea of this format is for the chain router to match by full name (`native:object//cnrID/objID`) or
|
||||
wildcard (`native:object//cnrID/*`).
|
||||
|
||||
Check out formats that are defined in the schema: [native formats](../schema/native/consts.go), [s3 formats](../schema/s3/consts.go).
|
||||
You should validate a resource name using [util](../schema/native/util/validation.go) before instantiating a request or
|
||||
before putting it to either to local override storage or the policy contract storage.
