远程访问虚拟专用网络（VPN）使远程工作的用户能够安全地访问企业数据中心和总部的应用程序和数据，并对用户发送和接收的所有流量进行加密。

安全的远程访问 VPN 在网络和远程用户之间创建了一条几乎不公开的隧道。流量经过加密，窃听者无法读取。远程用户可以像在办公室一样安全地访问和使用网络。利用远程访问 VPN，可以在没有截获或篡改风险的情况下传输数据。

## 远程访问 VPN 如何工作？

![远程位置的笔记本电脑通过互联网和网络访问服务器，通过远程访问 VPN 连接到主办公室。](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/remote-access-vpn.png "远程位置的笔记本电脑通过互联网和网络访问服务器，通过远程访问 VPN 连接到主办公室。")

远程访问 VPN 的工作原理是建立用户设备与企业网络之间的安全加密连接。这一过程首先由 VPN 客户端管理初始验证过程，确认只有授权用户才能建立连接。通过身份验证后，VPN 客户端软件就会创建一条通往 VPN 网关的加密隧道。网关充当 VPN 服务器，为数据传输提供安全路径。

即使在公共互联网网络上，通过隧道传输的所有数据也都经过加密，从而保护了数据的机密性和完整性。安全隧道将网络边界延伸至远程用户，基本上将他们置于企业网络内。该流程允许安全访问应用程序、文件服务器和数据库等内部资源。

远程 VPN 通常具有安全功能，包括多因素验证和高级加密标准。额外的安全层可确保连接的私密性，并保护企业网络免受远程设备带来的潜在威胁。

## 远程访问 VPN 的优势

![远程访问 VPN 的优势](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/benefits-of-remote-access-vpn.png "远程访问 VPN 的优势")

### 安全的远程连接

远程访问 VPN 可确保远程工作人员和移动用户与企业网络连接的安全。它对数据流量进行加密，确保敏感信息的保密性和完整性。

### 潜在的成本效益

实施远程访问 VPN 有时是一种经济有效的解决方案，可以将网络访问扩展到办公室物理范围之外。对一些公司来说，它可以推迟最初对大量基础设施投资的需求。

### 简化管理

远程访问 VPN 为用户访问和安全策略提供单点控制，从而简化了网络管理。管理员无需进行复杂的现场配置，即可轻松管理连接、监控安全和执行策略。

## 远程访问 VPN 面临的挑战

![远程访问-vpn-挑战](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/remote-access-vpn-challenges.png "远程访问-vpn-挑战")

从历史上看，远程访问 VPN 是为远程工作人员提供访问企业资源的主要手段。然而，随着网络架构的发展和安全威胁的日益复杂，这些 VPN 有时会面临挑战，特别是与更现代化的解决方案相比。

### 有限的安全措施

传统的远程访问 VPN 除了基本的加密和身份验证外，没有提供足够的安全控制。它们可能缺乏执行细粒度访问控制的能力，从而使敏感的企业资源有可能遭到未经授权的访问。

### 不一致的用户体验

远程访问 VPN 的用户体验可能不一致，有时还很麻烦，这取决于提供商和平台。连接问题和手动登录的需要会阻碍工作效率，让远程员工感到沮丧。

### 复杂的管理和可扩展性

随着组织的发展，管理远程访问 VPN 可能会变得复杂而耗时。为容纳越来越多的远程工作用户而进行大规模扩展，往往需要额外的硬件，并可能导致大量的管理开销。

### 暴露于网络漏洞

远程访问 VPN 可能会使网络面临漏洞，特别是在端点设备受到威胁的情况下。由于 VPN 通常不会对设备的安全状况进行评估，因此可能会无意中成为恶意软件或其他网络威胁的通道。

## 远程访问 VPN vs. 站点到站点 VPN

站点到站点 VPN 和远程访问 VPN 的主要区别在于网络连接架构和使用案例。

站点到站点 VPN 将整个网络连接在一起。它们能确保网络边缘的流量安全，让不同的站点共享资源，就像它们是同一个网络的一部分。

远程访问 VPN 适合希望从遥远的地方访问网络的个人用户。这些 VPN 利用安装在每个用户设备上的客户端软件，创建一条通往网络的安全隧道。

## SASE 作为远程访问 VPN 的现代替代方案

![SASE 架构图，显示用户流量来源和数据目的地，以及集成的网络和安全服务。](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/sase-architecture-vpn.png "SASE 架构图，显示用户流量来源和数据目的地，以及集成的网络和安全服务。")

SASE 架构图，显示用户流量来源和数据目的地，以及集成的网络和安全服务。 远程工作人员的增加趋势和软件即服务（SaaS）的发展导致了数字流量的变化。流量不再主要流向数据中心，而是越来越多地流向互联网和云服务。

安全访问服务边缘（SASE）作为一种确保远程工作人员持续、安全访问的解决方案应运而生。SASE 将广域网 (WAN) 的功能与强大的企业级可测量安全措施相结合，形成了一种集成的云原生服务。这种方法能有效地将组织的网络安全、安全协议和操作程序合并到一个精简的系统中。

SASE 代表着安全碎片化的重大转变。它摒弃了由不同供应商提供多种本地部署安全解决方案的传统模式，转而专注于基于云的统一网络安全结构。这种架构不仅增强了安全性，还提供了整合各种安全服务的适应性。

## 远程访问 VPN 常见问题

### 远程访问 VPN 有哪些风险？

远程访问 VPN 可能会带来一些风险，例如可扩展性有限、潜在的安全漏洞，以及在管理访问控制方面的复杂性增加。

### VPN 和远程连接有什么区别？

VPN 为数据传输创建一个安全的隧道，而远程连接泛指任何从非本地来源对网络的访问。

### 远程访问 VPN 和个人 VPN 有什么区别？

远程访问 VPN 将用户连接到企业网络，而个人 VPN 则保护用户的互联网连接。

### 如何为远程访问设置 VPN？

要为远程访问设置 VPN，需要在设备和网络之间配置安全连接，通常涉及软件安装和网络配置。具体设置过程因 VPN 服务而异。

### 什么情况下不应该使用 VPN？

当要求采用安全、可扩展和简化的解决方案时，或者当组织的政策建议不要使用 VPN 时，就不应该使用 VPN。

### 远程访问为什么需要 VPN？

远程访问需要 VPN 解决方案，以确保数据在不受信任的网络上安全传输。

### 远程访问 VPN 的替代方案有哪些？

远程访问 VPN 的主要替代方案包括安全访问服务边缘 (SASE)、零信任网络访问 (ZTNA) 和软件定义广域网 (SD-WAN)。

### VPN 作为远程访问解决方案的三个缺点是什么？

VPN 的三个缺点是：可能会降低网速，可能不支持所有应用程序，管理起来可能比较复杂。

### 远程访问比 VPN 更安全吗？

在使用 SASE 等提供集成安全功能的现代解决方案时，远程访问可能被认为比 VPN 更安全。

### 什么比 VPN 更安全？

安全接入服务边缘（SASE）通过在云原生服务中结合网络和安全功能，提供比传统 VPN 更佳的安全性。

### 什么是客户端到站点 VPN？

客户端到站点 VPN 也称为远程访问 VPN，允许设备通过互联网上的加密隧道安全地连接到远程网络。这种设置使用户能够访问网络资源，就像他们实际在同一个本地网络上一样。

### 客户端到站点 VPN 如何工作?

客户端到站点 VPN 有时也称为远程访问 VPN，其工作原理是建立用户设备到 VPN 服务器的安全连接，为数据创建加密隧道。这一过程会对远程用户进行身份验证，并对设备和网络之间交换的数据进行加密，确保资源访问的安全性。

### 客户端 VPN 和站点到站点 VPN 有什么区别？

客户端到站点 VPN 通过互联网将个人设备连接到网络，使用加密技术确保数据安全。而站点到站点 VPN 则是将整个网络相互连接起来，实现站点之间的安全通信，而无需对每个终端用户设备上的流量进行加密。
