What is Sock? Compare the difference of SOCKS Proxy and HTTP Proxy

SOCKS is an early and widely used protocol

SOCKS is an early form of protocol and is most commonly used today. This is considered a useful tool for establishing a quality, fast and secure network connection.

So What is SOCK? And what are its features? What are the similarities and differences between SOCKS Proxy and HTTP Proxy? Join Mat Bao to learn about issues related to this type of protocol through the following article.

What is SOCK?

1. What is SOCK?

SOCKS is a form of internet protocol, in which network packets (network packets) will be exchanged between server and client through Proxy Server. In essence, SOCKS manages and monitors the connection using SOCKERs. They are classified into two types: servers that are added to the Proxy Server when purchasing a server and clients that are integrated directly into web browsers.

SOCKS Server handles requests (requests) from clients behind the firewall of the enterprise network. Its task is to deny / allow the request depending on the final arrival time of the request or user identification information. Once the connection and request frequency are established, the return signal from the server will return to the normal protocol. At the same time, they will also be displayed right on the user’s computer.

2. What is the difference between SOCKS Proxy and HTTP Proxy?

SOCKS Proxy and HTTP Proxy are two terms that are easily confused with each other. Their biggest common point is that they both perform the task of transferring data and cannot encrypt data. Therefore, the encryption will be responsible for the user’s computer.

After understanding the concept “What is SOCK??”, you can easily recognize the difference between the two terms mentioned above.

  • Difference in features

HTTP Proxy only uses the HTTP protocol so their functionality will depend on what the protocol provides. Meanwhile, SOCKS is considered as a lower-level proxy, independent of a specific protocol and used for more general purposes. Thus, compared to HTTP Proxy, SOCKS has more flexibility, users can use this proxy anywhere they want.

  • Differences in security capabilities

The main function of a proxy is to ensure the safety and confidentiality of online information access. In terms of security, SOCKS proxy is still more appreciated than HTTP Proxy. Because with HTTP Proxy, the user’s data can still be viewed or recorded when the server and client connect. In contrast, SOCKS Proxy cannot read data because they are only responsible for delivery.

  • Speed ​​difference

HTTP Proxy provides 2 types of proxies: private (private) and public (public). Private proxies help users manage their online activities independently, with less problems. Meanwhile, public proxy speed can be affected by the number of users. SOCKS Proxy makes a difference in terms of speed. It is ideal for transferring or downloading data online because it reduces the need to apply encryption.

  • Differences in connectivity with tools

Tool connectivity is one of the answers to the question “what is the difference between HTTP and What is SOCK??”. HTTP Proxy’s server can connect to many tools, and SOCKS Proxy is the opposite. With the above characteristics, SOCKS Proxy will be suitable for those who need to transmit or download large amounts of data.

3. What can SOCKS do?

The most important feature of SOCKS is to support and ensure the security of data exchange. SOCKS5 Proxy is the most up-to-date and modern version of the SOCKS protocol. This protocol is improved from SOCKS4, which integrates UDP and TCP for enhanced security.

SOCKS can support:

  • Alternative access management for VPN.
  • Verify Captcha Gmail to access Gmail.
  • Access the local services located behind the SOCKS Server.
  • Increased processing speed for international connections.
  • Bypass Firewall – bypass the firewall.

4. SOCKS works with more protocols

In computer science terms, SOCKS is a high-level proxy that works with more protocols. SOCKS operates at layer 5 (session layer), lower than layer 7 of the HTTP Proxying protocol in the OSI model, and supports TCP packet forwarding.

SOCKS works with multiple protocols

Upgraded version of SOCKS5 Proxy Server to integrate user authentication and UDP packet forwarding. Through that, SOCKS will use the protocol associated with the client to collect information about the destination address that the client wants to connect to. Next, the information will be reported to the proxy software to work seamlessly with the user.

So what makes it possible to work with multiple protocols of What is SOCK?? That is the specialty, SOCKS understands many languages, handles many protocols, including HTTP. In other words, it is the most efficient option for dealing with different protocols, for example POP for email.

5. SOCKS can bypass the firewall

Compared to HTTP, SOCKS is able to bypass more types of firewall algorithms thanks to its secure and tight encapsulation of data. This protocol uses TCP to connect to the server, so it does not need to go through the same traffic routes as HTTP. Specifically, SOCKS can evade the surveillance firewall system, browse the content blocked or restricted by the website firewall.

6. HTTP Proxy handles HTTP requests better than SOCKS

SOCKS Proxy works with multiple protocols and effectively bypasses firewalls, but HTTP Proxy has the upper hand in handling HTTP traffic. This is due to the fact that HTTP Proxy is equipped with more specialized HTTP processing engines than SOCKS Proxy.

The knowledge related to SOCKS is something that you need to learn when you want to develop a network to improve business efficiency. Hope the above article of Mat Bao has helped you answer the question “What is SOCK??” as well as understand more about the features of this type of protocol.
