Privacy and security are crucial factors everyone checks when surfing the internet. But it’s hard to achieve the recommended levels if you don’t have the right tools. Without them, the internet is just an open cyberspace with all the risks such as government surveillance, monitoring and tracking and also other threats such as Man-in-the-middle (MITM) attacks from cybercriminals. Apart from security and privacy, there are also other issues such as geo restrictions and censorships which strip away your internet freedom and digital rights.
为了避免上述互联网不公正现象，VPN 和代理等工具是必要的。这些工具可以确保你在上网时恢复隐私，安全不受影响。下面将详细介绍 VPN 和代理服务器的工作原理，以及哪种工具最适合这项工作。
虚拟专用网
VPN or Virtual Private Network is a service with an infrastructure that comprises a network of secure servers. These servers form an encrypted tunnel in which internet traffic passes between a client and the open internet.
VPN 如何工作
A VPN’s primary functions include privacy and security. A VPN accomplishes these functionalities by hiding your IP and through encryption. When you connect to a VPN, you are assigned one of the VPN’s server IP addresses – IP address is your unique identifier on the internet – and hence your real IP address is masked (not visible on the internet). In a nutshell, this is how a VPN achieves privacy and anonymity.
For security, VPNs use unbreakable encryptions such as the AES 256-bit and also secure protocols such as OpenVPN. Encryption ensures your internet traffic is scrambled and no one will be able to read it even if its intercepted. With this security, you’ll be safe from cybercriminals, government surveillance and even your Internet Service Provider (ISP). Some VPNs have added functionalities such as a kill switch and DNS leak protection which ensure maximum privacy and security. Others have a zero-logging policy, and hence they don’t log any activity you do on the internet.
一些 VPN 优点包括
- 无可挑剔的安全和隐私
- 帮助您访问受地域限制的内容
- 绕过封锁和审查
- 高速服务器
- 易于使用
缺点包括
- VPN 可能很贵
- Free VPNs can put your privacy at risk
代理
Proxy is a general term but, in this case, it refers to proxy servers. These are specialized servers that act as a medium connection between your computer and the services you want to access the internet.
工作原理
When connecting to the internet using proxy servers, your IP address is hidden. Here’s is how; proxy servers use different IP addresses to service your request when accessing the internet, they then send the results back to your computer. By using proxy servers as your intermediary, anybody tracking you will land at the proxy server instead of your computer. This is how proxy servers achieve privacy. For security, some proxy servers may offer secure protocols and even firewalls to protect you against internet vulnerabilities and threats.
有时，在访问某些网页时，代理服务器会因缓存而提供更快的连接速度。根据服务器的规格，连接速度可快可慢。
使用代理的优点包括
- 与任何允许代理地址的设备兼容。
- 服务器的优势，如速度
- 访问受限内容
缺点包括
- 安全性不可靠
- 您将获得累积的服务器弊端，如恶意软件
- 配置代理很难
Comparing the above services, a VPN is a much better service as it provides excellent security and privacy, and that’s what is needed in the open internet.
