+# 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.  
+![Storage node](images/ape/storage_node_ape.svg)
+
+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)

+### 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
+provided into convert function.
+
+For example such AWS json statement:
+
+```json
+{
+  "Effect": "Allow",
+  "Action": "*",
+  "Resource": "*",
+  "Principal": {
+    "AWS": "arn:aws:iam::111122223333:user/JohnDoe"
