How important are SOCKS proxies to your internet connection? Do you even need them? Read on to find the answers to these questions.
The internet has become an indispensable part of our lives today. Despite its importance, one of the questions that need answering is the issue of cyber safety and security. How safe are we from cybercriminals and malicious organizations while surfing the internet?
In this article, we will discuss an essential security item when it comes to the workings of the internet. This item is known as SOCKS proxy. You will get the necessary details about SOCKS proxies, how they work, and their benefits in this article.
What is a SOCKS Proxy?
SOCKs is an acronym for Socket Secure. It is a network protocol that bypasses an internet blockade by channeling network traffic through a proxy server on behalf of the client. A SOCKS proxy works by creating a TCP (Transmission Control Protocol) connection with another server behind the blockage. This connection then serves as a means of exchanging network packets between the client and the server.
Types of SOCKS Proxy
There are two types of SOCKS proxy. These are SOCKS4 and SOCKS5, SOCKS5 being the latest version of the SOCKS proxy. Its major difference from SOCKS 4 is the fact that it offers some forms of authentication. Some of the authentications offered by the SOCKS5 proxy includes
- Null Authentication: You do not need any authentication before you connect to a proxy in the type.
- Password/Username Authentication: In this type, you need to provide login details which include username and password before connecting to a proxy.
- GSS-API Authentication: In this type of authentication, you and the server need to verify your identity at the operating system level.
Apart from the authentication difference, other differences between a SOCKS4 proxy and SOCKS5 proxy includes better security on the part of SOCKS5 through the use of TCP connections and SSH tunneling. Also, SOCK5 supports UDP, while SOCKS4 does not.
How Does SOCKS Proxy Work
If you decide to use a SOCKS proxy, the proxy will create a TCP connection with a proxy server. The proxy server, with another IP address, will be able to connect to the website and obtain data from the website. The proxy server then sends the data to the SOCKS proxy, thorough the TCP connection, which sends the data to you (the client).
The SOCKS proxy also provides some excellent security features attributable to its layer 5 protocol. While the layer 5 protocol means that you cannot use the proxy to tunnel anything below layer 5, it also means that hackers will not be able to perform scans on your connection if they are using Nmap. This is because Nmap working with half-closed connections works below layer 5.
Advantages of Using SOCKS Proxy
There are numerous reasons why you should use a SOCKS5 proxy. While we may not be able to discuss all of these benefits in this article, here are some of the most important advantages of using the SOCKS proxy;
- Helps you Bypass Internet Blockage
Being the first purpose of a SOCKS proxy, the ability to bypass an internet blockade is also the most vital benefit of a SOCKS proxy. Apart from helping you gain access to geo-restricted web content, it is also useful for developers. Let’s take an example of a situation where the backend services of a certain web application are put in a cluster and hosted in the cloud. This is a security measure aimed at reducing the security vulnerabilities of the services. Normally, you may not be able to access it.
In fact, there are two ways of trying to access such backend services. These methods are both fraught with adverse security aftermaths. The first one is to expose the backend service to the public and accept the security risks that come with it. The second method is whitelisting specific IP addresses to allow them access to the backend service. This method poses a security risk when the user changes the IP address. As such, the two methods are not safe.
This is where SOCKS proxies come in, as an alternative to these two methods. When you combine a SOCKS proxy with an SSH tunnel, you can access any backend service in a cluster without exposing it to any form of security risks.
- Faster and Reliable Internet Connection
SOCKS5 offers a fast and strong internet connection when used. This benefit is due to the use of the UDP protocol as against the conventional TCP connection that its predecessor, SOCK4 uses. The purpose of a TCP connection is to ensure that all network packets from one end of the connection get to the other.
To do this, the TCP connection has to convert the packet into another format, to enable easy passage. The process of converting the network packets takes time, and this causes a slow internet connection. With the use of the UDP protocol, you can avoid this conversion process. The protocol doesn’t convert network packets into any fixed format, and this accounts for its faster internet speed.
- Improved Connection Performance and Fewer Errors
When in use, most proxies tamper with packet headers and rewrite them. In most cases, this action leads to mislabeling and errors in routing the data packets. However, you need not worry about this with the SOCKS5 proxy. The proxy does not relabel the data packets, and thus, there is no possibility of misrouting. By extension, you will enjoy an overall improved internet connection.
It is important to note that the failure of SOCKS5 to relabel the headers on data packets is a possible security risk. The header usually contains your details, and when they are not rewritten, it comes easily identifiable.
- No Need for a Special Setup
Remember how we talked about using a SOCKS proxy to access a clustered backend service hosted in the cloud? The good thing is, with SOCKS5, you don’t need a special setup to access the service, as long as you have an SSH tunnel. This means that as a developer or administrator, you don’t need a VPN.
Disadvantages of Using SOCKS Proxy
These are some of the few benefits of using a SOCKS proxy, especially the SOCKS5 proxy. Let’s see some of the drawbacks and disadvantages of using a SOCKS proxy.
- Proxy Providers Might Track You
While SOCKS proxies do a great job of masking your IP address on the internet, the provider of the proxy server in use might spy on you and track your internet activities. This is why it is necessary to research the proxy provider you intend to use before using them.
- Your Data Might Not Be Encrypted
One of the purposes of a SOCKS proxy is to provide some form of anonymity by encrypting your internet data. Most providers use SSL certificates to do this. However, SSL certificates are not enough to provide adequate encryption as hackers and cybercriminals can use SSL stripping to undo the encrypted connection.
For these reasons, you may want to use a VPN in conjunction with the SOCKS proxy server.
Some companies offer SOCKS proxies for sale. You pay some amount of money for the proxies, allowing you to connect to the internet without worrying about blockades. These providers are divided into two; Residential SOCKS proxy providers and Datacenter SOCKS proxy providers.

1. Are SOCKS proxies illegal?
SOCKS proxies are legal in every country in the world. Apart from protecting people against cybercriminals, they also enable remote working. It also allows people outside a particular network to access support systems.
2. When Do I Need SOCKS Proxies?
You need SOCKS proxies when any type of blockade restricts your access to a server. If you need to bypass the blockade, SOCKS proxies are your go-to option.
3. Which is better: Residential or Datacenter SOCKS Proxies?
While both types of SOCKS proxies have their inherent benefits and drawbacks, residential proxies are better than datacenter proxies. This is because residential proxies use a real IP address traceable to a real device.
The SOCKS proxy, especially SOCKS5, is a very useful aspect of internet connection as it helps bypass internet blockades. It also trumps other types of proxies as it works with other protocols such as HTTP, SMTP, and FTP. While it is faster and cheaper than a VPN, it doesn’t offer the same level of security as the VPN does.
