Local security software company Esphion says the technology exists to trace the source and eliminate the denial of service problem of DALnet (see Frustrated IRC users point to music industry), but it carries a cost.
One of the chief problems with organisations like DALnet is that they are not-for-profit ventures, and probably cannot afford to buy the technology.
Espion has developed a specialist DDoS analysis and prevention product, NetDef-lect, demonstrated last year to international armed forces at the Joint Warrior Interoperability (Jwid) exercise.
Kevin Black, who calls himself a strategist at Esphion, says he has emailed the DALnet proprietors about the problem and potential approaches, but as at last week had had no reply.
“I’ll try again,” he says, suggesting that if a NetDeflect service could be brought down to within DALnet’s budget, “it might be a good marketing exercise for us”.
NetDeflect could almost certainly identify the source of the attacks and block them, he claims.
