SOCKS Agenda What is SOCKS? Characteristic/Advantages of SOCKS Applications Security Case Study Reference Q&A

What is SOCKS? SOCKS = Secured Over Credential-based Kerberos Services Proxy definition: Server that relays request from a client to a server SOCKS is protocol that defines the communication from user to the proxy SOCKS relays a user’s TCP/UDP session over a firewall. Allow transparent access for the application users.

What is SOCKS? Similar to a HTTP Proxy

Characteristics and advantages of SOCKS SOCKS is part of Session layer. Transparent support for any protocols above of Session layers.

Characteristics and advantages of SOCKS Two versions of SOCKS SOCKSv4 SOCKSv5 How does it work: 3 steps Generation of connection requests Establishment of proxy circuits Relaying applicative data Authentication (only in version 5)

Characteristics and advantages of SOCKS Any applications can use SOCKS Support UDP (version 5) Proxy bi-directional Use domain name (DNS) instead of IP address Authentication is available in version 5 to assure user identity and its privileges.

Applications SOCKS can be use by anyone, companies or individual Sample Servers available online: SS5 Socks Server OpenSSH (support SOCKS) WinSocks - Socks Proxy Server Sample Clients available online: WideCap HTTP-Tunnel Client ProxyCap

Security about SOCKS ONLY a protocol that routes network packets between client and the SOCKS proxy server No built-in security feature besides Authentication in Version 5 Needs to pair with security protocol to secure communication: ex, SSH, HTTPS, etc. Security Goal Features Confidentiality None Integrity Authentication Available in V5

SOCKS Case Study: HTTP Proxy With Firewall

SOCKS Case Study: SOCKS Proxy with Firewall SOCKS Proxy overview behind firewall

SOCKS Case Study: SOCKS Proxy Data sent between User and SOCKS Proxy are not secured. No Confidentiality/Integrity is guaranteed Authentication is available in Version 5 only. Recommend to use SSH Tunnel between User and SOCKS Proxy. HTTP Request still in clear text leaving SOCKS Proxy => Use HTTPS.

SOCKS Case Study: Anonymity Software using SOCKS TOR uses SOCKS proxy to provide anonymity to users.
