Which statement about the SOCKS proxy is true?
Key statements about the SOCKS proxy on a Cisco WSA:
- Protocol support - SOCKS is a separate proxy protocol (SOCKS4 and SOCKS5) that operates at a lower OSI layer than HTTP proxies
- Application support - SOCKS can proxy non-HTTP applications and protocols, making it useful for applications that don't support HTTP proxies
- UDP support - SOCKS5 (unlike SOCKS4) supports UDP traffic in addition to TCP
- Authentication - SOCKS5 supports username/password authentication, while SOCKS4 does not
- Limited inspection - Unlike HTTP proxies, SOCKS proxies cannot inspect application-layer content for many protocols
- Client configuration - Applications must be explicitly configured to use SOCKS proxy (cannot be transparently intercepted)
The exact correct statement depends on the specific options provided, but typically focuses on SOCKS5's ability to support various protocols, authentication, and UDP traffic.
