Cloudflare har implementeret<\/a><\/noindex> siden isBGPSafeYet.com<\/a><\/noindex>, der har til form\u00e5l at g\u00f8re opm\u00e6rksom p\u00e5 problemet med l\u00e6kage af forkerte BGP-ruter og muligheden for at udf\u00f8re omdirigering af trafik ved hj\u00e6lp af BGP-protokollen. Siden giver mulighed for at kontrollere anvendelsen af ruteringsfiltreringsteknologi af udbydere og vurdere implementeringen af RPKI-support. <\/p>\n

Mange operat\u00f8rer forbliver ubeskyttede mod BGP-anmeldelser af subnetv\u00e6rk med falske oplysninger om rute l\u00e6ngde, som dirigerer transit trafik gennem tredjeparts udbydere. Der opst\u00e5r oftere tilf\u00e6lde af BGP-misbrug til angreb, hvor angribere ved at kompromittere udbydernes infrastruktur organiserer omdirigering og opsnapning af trafik for at erstatte specifikke websteder gennem gennemf\u00f8relse af MiTM-angreb for at \u00e6ndre DNS-svar. <\/p>\n

L\u00f8sningen p\u00e5 problemet er implementeringen af et autoriseringssystem for BGP-anmeldelser baseret p\u00e5 RPKI (Resource Public Key Infrastructure), som g\u00f8r det muligt at bestemme, om BGP-anmeldelsen kommer fra netv\u00e6rksejeren eller ej. Ved brug af RPKI for autonome systemer og IP-adresser opbygges en tillidsk\u00e6de fra IANA til regionale registrarer (RIRs) og derefter til udbydere (LIR) og slutbrugere, som g\u00f8r det muligt for tredjeparter at bekr\u00e6fte, at operativt med ressourcen blev udf\u00f8rt af ejeren. Desv\u00e6rre anvendes RPKI stadig ikke af st\u00f8rstedelen af udbyderne trods problemerne. Den nye tjeneste fra Cloudflare g\u00f8r det muligt at spore problematiske operat\u00f8rer og v\u00e6kke offentlig opm\u00e6rksomhed omkring dem.
