From the basic building blocks of the internet to cryptocurrency mining on a supercomputer, SOCKS sits at the core of computing. A SOCKS proxy can be used to improve network security in an enterprise, but can also be exploited by cybercriminals for nefarious reasons. Take a look at how SOCKS proxies have been manipulated recently by threat actors.
SOCKS, which stands for Socket Secure, is an internet protocol that enables the exchange of packets between a client and a server through a proxy server.
According to the Internet Engineering Task Force, the protocol is “designed to provide a framework for client-server applications in both the TCP (transmission control protocol) and UDP (user datagram protocol) domains to conveniently and securely use the services of a network firewall.”
A proxy server functions as an intermediary for requests from a client in an internal network seeking services or resources from the internet. The proxy server has its own public IP address.
There are a number of use cases for a proxy server: to improve network security, carry out actions anonymously, balance network traffic, control employee internet usage and provide faster network speeds by compressing traffic, caching files and stripping ads from websites.
There are currently two versions of SOCKS: SOCKS4 and SOCKS5. SOCKS5 is the current version of the protocol. It supports a variety of authentication methods, as well as User Datagram Protocol (UDP) proxies.
There are several benefits to using the latest version of SOCKS for a proxy server. First, it enables an administrator to access backend servi ..
