If necessary, the authentication option described in [RFC3118] should be utilized. With regard to security considerations specific to the use of this DHCP option for iSNS server discovery, exposure to a "man-in-themiddle" attack by a hostile entity modifying or replacing the original iSNS option message should be considered a potential security exposure. If the authentication option in [RFC3118] is not implemented, then an attacker may trick the iSNS client into connecting into rogue iSNS servers. If the authentication option for DHCP is not implemented and it is determined that the potential exists for a "man-in-the-middle" attack, then the DHCP option message for iSNS should not be utilized. ====================== What's wrong with that?
