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.
為了避免上述互聯網不公正，VPN和代理等工具是必要的。這些工具可確保您收回隱私，並且在上網時安全性不會受到損害。以下是有關VPN和代理如何工作的詳細資訊，以及哪種工具最適合這項工作。
VPN的
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 的工作原理
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 專業人士包括;
- 無可挑剔的安全性和隱私性
- 幫助您訪問受地理限制的內容
- 繞過封鎖和審查
- 高速伺服器
- 易於使用
缺點包括;
- VPN 可能很昂貴
- 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.
有時，由於緩存，代理在訪問某些網頁時可能會提供更快的連接速度。根據伺服器的規格，連接可能很慢或更快。
使用代理的優點包括;
- 與任何允許代理地址的設備相容。
- 伺服器優勢，如速度
- 訪問受限內容
缺點包括;
- 安全性方面的不可靠性
- 你會得到累積的伺服器缺點，如惡意軟體
- 很難配置代理
