Cloudflare inf\u00f6rt<\/a><\/noindex> webbplats isBGPSafeYet.com<\/a><\/noindex>, syftar till att uppm\u00e4rksamma problemet med l\u00e4ckage av felaktiga BGP-rutter och m\u00f6jligheten att genomf\u00f6ra trafikomdirigeringattacker med hj\u00e4lp av BGP-protokollet. Webbplatsen m\u00f6jligg\u00f6r kontroll av till\u00e4mpningen av felruttfilterteknologi av leverant\u00f6rer och bed\u00f6mning av implementeringen av RPKI-st\u00f6d. <\/p>\n

M\u00e5nga operat\u00f6rer f\u00f6rblir oskyddade mot inkommande BGP-annonser f\u00f6r subnet med falsk information om ruttens l\u00e4ngd, vilket dirigerar transittrafik genom tredje parts leverant\u00f6rer. Allt oftare dyker det upp fall av att BGP anv\u00e4nds f\u00f6r attacker d\u00e4r angripare, genom att kompromettera leverant\u00f6rernas infrastruktur, organiserar omdirigering och avlyssning av trafik f\u00f6r att f\u00f6rfalska specifika webbplatser genom att genomf\u00f6ra MitM-attacker f\u00f6r att ers\u00e4tta DNS-svar. <\/p>\n

L\u00f6sningen p\u00e5 problemet \u00e4r att implementera ett BGP-annonseringsautorisationssystem baserat p\u00e5 RPKI (Resource Public Key Infrastructure), vilket g\u00f6r det m\u00f6jligt att avg\u00f6ra om en BGP-annons kommer fr\u00e5n n\u00e4tverks\u00e4garen eller inte. N\u00e4r RPKI anv\u00e4nds f\u00f6r autonoma system och IP-adresser byggs en f\u00f6rtroendekedja fr\u00e5n IANA till de regionala registrarna (RIRs), och sedan till leverant\u00f6rerna (LIR) och slutkonsumenterna, vilket g\u00f6r det m\u00f6jligt f\u00f6r tredje parter att verifiera att en operation med resursen har utf\u00f6rts av dess \u00e4gare. Tyv\u00e4rr anv\u00e4nds RPKI fortfarande inte av st\u00f6rre delen av leverant\u00f6rerna. Den nya tj\u00e4nsten fr\u00e5n Cloudflare g\u00f6r det m\u00f6jligt att sp\u00e5ra problematiska operat\u00f6rer och uppm\u00e4rksamma dem offentligt.
