Ensure nonlocsrcroute is disabled

OrtaDüzey 1Otomatikaix

Açıklama

The nonlocsrcroute parameter determines whether the system allows source routed packets to be addressed to hosts outside of the LAN. The nonlocsrcroute parameter will be set to 0. This means that the system will not allow source routed packets to be addressed to hosts outside of the LAN. By default, when this is enabled the system is susceptible to source routing attacks. Audit: `no -o nonlocsrcroute` must report 0.
