![]() ![]() On the client side, a VPN profile may not necessarily be configured as a full-tunnel solution, hence only part of your web traffic could be going through the VPN, and the rest leaked through your local ISP. You can configure additional SSH users to allow SOCKS5 proxying without a shell nor the ability to run commands on the server. Instead, proxying traffic via SSH means you already have a user account on a server you can securely connect to (using SSH keys), and do not need any additional setup, limiting the number of services exposed on your server, and using existing authentication methods. You'll have to separately configure it, set up user accounts, etc. Alternatively, you can set up your own OpenVPN server. You can use a VPN vendor, in which case your traffic goes through a server you do not own nor control. It depends on configuration and use case. This bypasses many content monitoring/filtering systems, and some Data Loss Protection (DLP) controls, since they typically assume HTTP(S), and do not have any introspection into your SSH traffic.Īs always, security and privacy are not guaranteed if the system is not yours. If you do not trust your local network, but trust your local machine and cloud jump box, it allows you to create an encrypted tunnel out of the network, and initiate your connections from outside. What's the benefit of encapsulating SOCKS within SSH?Ĭombining both adds a layer of encryption in transit, allows you to bypass firewalls, and makes your traffic originate from a different location. ![]() Toggle remote DNS depending on which network you want resolving those request. Therefore, system administrators controlling your local machine, or the machine you SSH into, may be able to see traffic that is not already encrypted at a higher layer. The traffic from your jump box to your destination is not encrypted.The traffic between your SOCKS proxy and your jump box (cloud instance VM) is encrypted within an SSH tunnel.The traffic between your browser and your SOCKS proxy is not encrypted.If you are using a protocol that does not offer a layer of encryption, like HTTP or DNS: If you are using HTTPS, your web traffic is encrypted between your browser, and the destination web server. What's the impact of SOCKS not encrypting traffic? It does not support network-layer gateway services, such as ICMP. It does not add additional encryption, which we get from SSH instead. The fifth version of the SOCKS protocol ( RFC1928) which operates at layer 5 of the OSI model, and proxies TCP and UDP connections. ![]()
