WSL 2.0 安全概述** WSL 2.0(Windows Subsystem for Linux 2.0)是一种允许在 Windows 10 和 11 中运行 Linux 发行版的子系统。与 WSL 1 相比,WSL 2 具有更好的性能和安全性。 WSL 2 的安全性基于以下关键概念: * **隔离:**WSL 2 使用 Hyper-V 创建一个隔离的虚拟机 (VM),在该 VM 中运行 Linux 发行版。这有助于防止 Linux 发行版中的恶意软件或漏洞影响 Windows 主机系统。 * **权限分离:**WSL 2 进程在与 Windows 主机系统不同的用户空间中运行。这有助于限制 Linux 发行版对 Windows 系统资源的访问。 # 2. WSL 2.0 安全配置实践 ### 2.1 子系统配置安全 #### 2.1.1 启用 Hyper-V 隔离 Hyper-V 隔离是 WSL 2.0 中的一项关键安全特性,它通过在主机和 WSL 子系统之间创建虚拟化层来增强安全性。启用 Hyper-V 隔离后,WSL 子系统将与主机系统隔离,从而降低恶意软件或攻击者从 WSL 子系统访问主机系统的风险。 要启用 Hyper-V 隔离,请执行以下步骤: 1. 打开 Windows 设置。 2. 转到“应用程序”>“可选功能”。 3. 勾选“Hyper-V”复选框。 4. 单击“安装”。 安装完成后,重新启动计算机。 #### 2.1.2 配置 WSL 网络隔离 WSL 网络隔离允许您控制 WSL 子系统与主机系统和外部网络之间的网络连接。通过配置网络隔离,您可以进一步增强安全性,防止恶意软件或攻击者通过网络访问主机系统。 要配置 WSL 网络隔离,请执行以下步骤: 1. 打开 Windows PowerShell。 2. 运行以下命令: ``` wsl --set-network <network-name> ``` 其中 `<network-name>` 是您要将 WSL 子系统连接到的网络的名称。 ### 2.2 主机系统配置安全 #### 2.2.1 启用 Windows Defender 防火墙 Windows Defender 防火墙是 Windows 操作系统中内置的防火墙,它可以阻止未经授权的网络连接。启用 Windows Defender 防火墙可以帮助保护您的主机系统免受恶意软件或攻击者通过网络访问。 要启用 Windows Defender 防火墙,请执行以下步骤: 1. 打开 Windows 设置。 2. 转到“更新和安全”>“Windows 安全”。 3. 单击“防火墙和网络保护”。 4. 启用“Windows Defender 防火墙”。 #### 2.2.2 配置 Wi
