Comprehensive research of Android Permission Mechanisms
Tags: security, opensource, androiddev, permission
Published: 2024-05-24 02:56:26

In the digital world of Android, the permission mechanism is the cornerstone of ensuring user privacy and data security. It is a critically important task for security researchers and engineers to thoroughly study and understand this mechanism. This article will explore four key aspects of the Android permission mechanism: the Uid permission mechanism under Linux, the Permission permission mechanism in Android, the enforcement strategies of SEAndroid, and the fine-grained permission control. 

Android is based on the existing permission management mechanism in Linux, which assigns different UIDs and GIDs to each application. The Uid permission mechanism isolates private data and access between different applications;

Android has added a permission mechanism to control the access permissions of components, hardware resources, etc. of Android applications;

The port from SELinux has also added permission control to access system services and other resources;

IPC (Inter-Process Communication) communication between Android apps requires access control through permission mechanisms.

## *Automated user migration and management of AWS Identity and Access Management (IAM) resources*

![](https://cdn-images-1.medium.com/max/3840/1*Pr78CMgUIOC2px6rFws54g.png)

In this project based on a real-world scenario, I acted as Cloud Specialist with the mission to migrate users in an automated way and manage AWS IAM (Identity and Access Management) resources.

There were 100 users that needed to be migrated and have MFA (Multi-factor authentication) enabled on their accounts, as this is a security best practice.

Using GitBash with AWS CLI and Shell Script, I avoided repetitive and manual tasks in the AWS console and automated the processes.

![](https://cdn-images-1.medium.com/max/3840/1*-RTS0j52RzHKrwWtakcSrw.png)

PART-1: On-Premises Migration to AWS

Create 5 user groups, attach policies, and migrate users from the on-premise environment

**CloudAdmin: A**dministratorAccess, IAMUserChangePassword

**NetworkAdmin: **VPCFullAccess, IAMUserChangePassword

**DatabaseAdmin:** AmazonRDSFullAccess, IAMUserChangePassword

**LinuxAdmin: **AmazonEC2FullAccess, IAMUserChangePassword

**Trainees: **ReadOnlyAccess, IAMUserChangePassword

PART-2: Enable MFA (MultiFactor Authentication) on your root and IAM users applying the IAM Password Policy

Create a custom policy, named **EnforceMFAPolicy.json, **for the MFA and add it to each user group, then enable it for root and each IAM user.

以下に、2つの回避方法をそれぞれ別々のコードとして示し、コメントアウトで解説を追加します。

### 方法1: `keys.clear();`を削除して例外を回避

```java
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class Main {
    // HashMapを作成してキーと値を格納するための静的マップ
    static Map<String, String> map = new HashMap<>();
    
    // 不変リストを使用 (例外が発生する可能性のあるリスト)
    static List<String> keys = List.of("A", "B", "C");
    
    // 値の配列を定義
    static String[] values = {"1", "2", "3"};
    
    // 静的初期化ブロックでキーと値をマップに追加
    static {
        for (int i = 0; i < keys.size(); i++) {
            map.put(keys.get(i), values[i]);
        }
    }
    
    public static void main(String[] args) {
        // 例外が発生するkeys.clear()の呼び出しを削除
        // keys.clear(); // この行を削除することで例外を回避
        
        // values配列を空にする
        values = new String[0];
        
        // マップのサイズ、キーリストのサイズ、values配列の長さを出力。3,3,0
        System.out.println(map.size() + "," + keys.size() + "," + values.length);
    }
}
```
### 解説:

1. **方法1: `keys.clear();`を削除して例外を回避**
   - `keys`リストは`List.of("A", "B", "C")`を使用して不変リストとして作成されています。
   - 不変リストのため、変更操作（例：`clear()`）はサポートされておらず、`keys.clear();`を呼び出すと`UnsupportedOperationException`が発生します。
   - この例外を回避するために、`keys.clear();`の行を削除しました。

map.size() は 3（マップには3つのキーと値のペアが格納されています）
keys.size() は 3（keysリストは不変であり、変更されないので3つの要素を持っています）
values.length は 0（values配列は空に変更されました）

### 方法2: 可変リストを使用して例外を回避

```java
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class MainWithMutableKeys {
    // HashMapを作成してキーと値を格納するための静的マップ
    static Map<String, String> map = new HashMap<>();
    
    // 可変リストを使用 (例外を回避するためのリスト)
    static List<String> keys = new ArrayList<>(List.of("A", "B", "C"));
    
    // 値の配列を定義
    static String[] values = {"1", "2", "3"};
    
    // 静的初期化ブロックでキーと値をマップに追加
    static {
        for (int i = 0; i < keys.size(); i++) {
            map.put(keys.get(i), values[i]);
        }
    }
    
    public static void main(String[] args) {
        // 可変リストの場合、keys.clear()は正常に動作する
        keys.clear(); // この行は正常に動作
        
        // values配列を空にする
        values = new String[0];
        
        // マップのサイズ、キーリストのサイズ、values配列の長さを出力。3,0,0
        System.out.println(map.size() + "," + keys.size() + "," + values.length);
    }
}
```

### 解説:
2. **方法2: 可変リストを使用して例外を回避**
   - `keys`リストを`new ArrayList<>(List.of("A", "B", "C"))`を使用して可変リストとして作成します。
   - これにより、`keys.clear();`が正常に動作し、例外は発生しません。
   - `keys.clear();`を呼び出しても問題なくリストをクリアすることができます。

map.size() は 3（マップには3つのキーと値のペアが格納されています）
keys.size() は 0（keys.clear();によってkeysリストが空になります）
values.length は 0（values配列は空に変更されました）

このコードは正しいです。抽象クラス `Item` には、一つの抽象メソッド `calcPrice` と、一つの具体的なメソッド `print` が含まれています。この構文は問題ありません。具体的なメソッド `print` には実装が含まれており、抽象メソッド `calcPrice` には `abstract` キーワードが付いています。

最終的なコードは以下の通りです：

```java
abstract class Item {
    public abstract int calcPrice(Item item);
    public void print(Item item) { 
        /* do something */ 
    }
}
```

この形式であれば、抽象クラスの定義として正しく、Javaコンパイラもエラーを出さないでしょう。

## 追記
はい、このコードにはいくつかの間違いがあります。抽象クラス `Item` には抽象メソッドが含まれていますが、抽象メソッドには `abstract` キーワードが必要です。また、抽象メソッドは実装を持たないため、セミコロンで終わる必要があります。

修正したコードは以下のようになります：

```java
abstract class Item {
    public abstract int calcPrice(Item item);
    public abstract void print(Item item);
}
```

このように、メソッドの前に `abstract` キーワードを追加し、メソッドの中身を削除してセミコロンで終わるようにします。

このコードスニペットでは、変数 `i` は実質的に `final` とは言えません。なぜなら、変数 `i` はラムダ式内で参照される前に再代入されているためです。具体的には、`i` がラムダ式内で使用される前に `i++` によってその値が変更されています。このため、コンパイル時にエラーが発生します。

以下は該当する部分を示します：

```java
void sample() {
    int i = 0;
    Supplier<Integer> foo = () -> i;
    i++; // ここで i の値が変更されるため、実質的に final ではなくなる
    System.out.println(foo.get());
}
```

このコードは、コンパイル時に以下のエラーが発生します：

```
local variables referenced from a lambda expression must be final or effectively final
```

ラムダ式で参照される変数 `i` が実質的に `final` と見なされるためには、その値が再代入されないことが必要です。したがって、再代入されるコードを削除または変更する必要があります。

修正例：

```java
void sample() {
    final int i = 0;
    Supplier<Integer> foo = () -> i;
    // i++; // この行を削除
    System.out.println(foo.get());
}
```

もしくは、

```java
void sample() {
    int i = 0;
    Supplier<Integer> foo = () -> i;
    System.out.println(foo.get());
    i++; // ラムダ式の後に i を変更
}
```

このように、ラムダ式内で使用する変数が変更されないようにすることで、実質的に `final` として扱われ、コンパイルエラーを回避できます。

## Heating up

Hey everyone, back here on another Friday for a quick update on our latest shenanigans. With summer fast approaching us, we can already start feeling warmer temperatures. Here in Northern Ireland we were even able to see a rare meteorological occurence that happens barely once or twice a year: sunshine!

Anyways, lets get started with the updates.

## Hackathon

Remember the ‘May the 4th be with you’ Hackathon? Well, since this year it fell on Saturday, we had to push it a bit further into the month. As a result, we had a ‘May the 21st and 22nd be with you’, which doesn’t sound all that exciting in comparison. But we still had fun and even managed to work on two small projects in parallel. One of them being a new potential update for our linter tool that would allow you to scan your repos for depecrated stdlib function usage (and output a warning about it) and the other being an experimental project around implementing AI usage within PDK to enhance developer experience around failure troubleshooting.

## LXD provisioning

We wanted to throw a massive shoutout to [Jeffrey Clark](https://github.com/h0tw1r3) for developing and pushing a new feature into our bolt-litmus-provision ecosystem to enable LXD provisioning. It took us a bit to get it merged but it should be available with the next releases of those tools.

## Community Contributions

We’d like to thank the following people in the Puppet Community for their contributions over this past week:

- [`pdk-templates#565`](https://github.com/puppetlabs/pdk-templates/pull/565): “Add bolt-related files to .gitignore default paths”, thanks to [jay7x](https://github.com/jay7x)
- [`provision#251`](https://github.com/puppetlabs/provision/pull/251): “LXD provisoner support”, thanks to [h0tw1r3](https://github.com/h0tw1r3)
- [`puppet_litmus#544`](https://github.com/puppetlabs/puppet_litmus/pull/544): “lxd provisioner support”, thanks to [h0tw1r3](https://github.com/h0tw1r3)

Imagine a messy Git repository, full of untracked files, build artifacts, and temporary files. What's the best way to remove all this unwanted content and keep the repository clean, freeing up space from your computer? Git offers a command called git clean and we'll learn about it in this post. Let's discover the command you didn't know you needed!

## What is Git Clean?

In simple terms, `git clean` removes untracked files from your working directory. This is useful for reducing clutter, streamlining development, avoiding conflicts, and enhancing the overall Git experience. Many projects generate caches, binaries, or download external libraries which can take up significant space. This command helps clean the entire repository.

Don’t worry, `git clean` doesn’t touch tracked files (files already staged or committed).

## How to Use Git Clean

The command is very simple to use. Just type `git clean` on the command line followed by some parameters. Here are the main parameters:

- **-d** : Removes untracked directories recursively.
- **-i** : Uses interactive mode. Git will show you all files or directories to be cleaned, and you’ll need to choose which ones to remove.
- **-f** : Forces `git clean` to clean the repository. By default, Git won’t clean anything unless you specify this parameter or use interactive mode. You can change this behavior by setting the Git configuration `clean.requireForce` to `false`. For more information on Git configuration, refer to the [Git Basics post](/en/git-basics-an-in-depth-look-at-essential-commands/).
- **-X** : Removes only files ignored by Git using the `.gitignore` file.

You can combine these parameters to perform different clean operations. After execution, you’ll see a list of deleted files.

```
git clean -dfX

Removing .DS_Store
Removing BookTracking.xcodeproj/xcuserdata/ionixjunior.xcuserdatad/xcschemes/
Removing BookTracking.xcworkspace/xcshareddata/
Removing BookTracking.xcworkspace/xcuserdata/ionixjunior.xcuserdatad/UserInterfaceState.xcuserstate
Removing Pods/
```

The `git clean` is very simple to use and extremely useful for freeing up space, especially in older projects that you aren’t actively working on.

## Conclusion

While simple, `git clean` is incredibly useful. Many times, we manually delete files, but this command comes to the rescue. If you want to free up space or have a clean working directory to rebuild your project without worrying about cached files, `git clean` is your solution. Stop doing things manually and use the power of Git to help you every day.
