Safe raw sockets are used to access raw network data, including IP, ICMP, UDP and TCP headers, while enforcing protection between different users (slices). No user is able to interfere with others by sending or receiving data on ports that have been registered to, or are currently being used by, other users. Sending data from an unregistered port or non-local IP address is also not allowed. Access to safe raw sockets does not require super-user privileges or the corresponding Linux capabilities.
