Xa umsebenzisi efaka idilesi yewebhu efana www.company.com, balindele ukufikelela kwindawo esemthethweni. Nangona kunjalo, abahlaseli banokusebenzisa ukuthembana kule nkqubo ukuze bathumele ithrafikhi kwiiwebhusayithi zobuxoki nezinobungozi. Olu lawulo lweNkqubo yeName yeDomain (DNS) lwaziwa ngokuba yi-DNS spoofing. Ngokusisiseko, sisongelo esibalulekileyo sokhuseleko lwenethiwekhi esinokubeka emngciphekweni ukuthembeka kwedatha, siveze abasebenzisi kuhlaselo lwe-phishing, kwaye sonakalise igama lombutho.
Ukwazi ukuba yintoni i-DNS spoofing kunye nokuba yintoni i-DNS spoofing attack kubalulekile kumaqela asebenzisa iziseko zanamhlanje, ingakumbi kwiindawo ze-DevSecOps, apho usetyenziso luxhomekeke kakhulu kwisisombululo se-DNS esithembekileyo se-APIs, CI/CD iinkqubo, kunye neenkonzo zelifu.
Yintoni i-DNS Spoofing Attack? #
Ukuze uqonde ukuba yintoni uhlaselo lwe-DNS spoofing, kufuneka uqale wazi indlela esebenza ngayo i-DNS. Inkqubo yeDomain Name isebenza njengefowuni ye-intanethi.ebook: idweba amagama eedomeyini (njenge api.service.com) kwiidilesi ze-IP zokwenyani ezisetyenziswa ziiseva ukunxibelelana.
Kwihlaselo lokukhohlisa lwe-DNS, umhlaseli uphazamisa loo maphu. Abahlaseli badla ngokufaka iirekhodi ze-DNS zobuxoki kwi-cache yomsombululi ukuze xa umntu ekhangela i-domain esemthethweni, umsombululi we-DNS abuyisele idilesi ye-IP engalunganga, leyo ekhomba kwisiza esinobungozi esiphantsi kolawulo lomsombululi.
Ukusuka apho, umdlalo uphelile: umsebenzisi uthunyelwa kwiwebhusayithi yobuxoki ebonakala iyinyani ngokwaneleyo ukuba imkhohlise ukuba afake iziqinisekiso okanye akhuphele into enobungozi. Ngamafutshane, ukukhohlisa nge-DNS kuxhomekeke kwinto enye kuphela: ukonakalisa inkqubo yokukhangela i-DNS ukuze kuthunyelwe ithrafikhi buthule ngaphandle kolwazi lomsebenzisi.
Isebenza njani i-DNS Spoofing Attack? #
Ukuze siqonde ngokupheleleyo ukuba yintoni i-DNS spoofing attack, makhe sihlolisise indlela abahlaseli abayenza ngayo ngokusesikweni (oku kubaluleke kakhulu). Apha unesishwankathelo esilula senkqubo:
- Ukuqaliswa koMbuzo we-DNS: Umsebenzisi okanye isixhobo sicela idilesi ye-IP yedomeyini, efana ne-example.com.
- Ukuvalelwa okanye ukuQhekezwa: Umhlaseli ubamba okanye aguqule impendulo ye-DNS ngaphambi kokuba ifikelele kumsebenzisi.
- Ityhefu yeCache: Idilesi ye-IP enobungozi igcinwa kwi-cache yomsombululi, ithatha indawo yeyosemthethweni.
- Ukwalathiswa kwenye indawo: Zonke izicelo zexesha elizayo kuloo domain ngoku zikhokelela kwisiza esilawulwa ngumhlaseli.
- Ukuxhaphaza: Umhlaseli usebenzisa indawo eqondiswe kwenye indawo ukuze ebe iziqinisekiso, afake i-malware, okanye enze uhlaselo lwe-phishing.
Olu landelelwano lwenza ukuba uhlaselo lwe-DNS olukhohlisayo lube yingozi kakhulu; umsebenzisi uhlala ebona igama lesizinda elilindelekileyo kwisikhangeli sakhe kwaye akaqondi ukuba indawo esisiseko itshintshile.
Iintlobo ezahlukeneyo zokuhlaselwa kwe-DNS Spoofing #
Xa uhlalutya ukuba yintoni i-DNS spoofing attack, kubalulekile ukuqaphela ukuba abahlaseli basebenzisa iindlela ezahlukeneyo ukufezekisa iinjongo zabo:
- Ityhefu ye-DNS Cache: Ukufaka iirekhodi ezingeyonyani kwi-cache yomsombululi ukuze abasebenzisi bafumane i-IP yomhlaseli endaweni yeyosemthethweni.
- Umntu-ophakathi-(MitM) DNS Spoofing: Umhlaseli ubamba unxibelelwano lwe-DNS aze athumele iimpendulo ezingeyonyani ngexesha langempela.
- Ukubiwa kwe-DNS: Umhlaseli ufumana ukufikelela kwizicwangciso ze-DNS kwi-domain registrar, nto leyo etshintsha iirekhodi ezisemthethweni.
- Iiseva zeDNS ezingasebenzi kakuhle: Iiseva ze-DNS ezinobungozi ngabom zibonelela ngezisombululo ezingezizo ezisemthethweni kwiindawo eziqhelekileyo.
- Ukuphamba kweNethiwekhi yasekuhlaleni: Kwi-Wi-Fi evulekileyo okanye kwiinethiwekhi ezingakhuselekanga, abahlaseli banokuthumela imibuzo ye-DNS yasekuhlaleni kwiindawo ezinobungozi.
Zonke ezi ndlela zineenjongo enye: ukukhohlisa inkqubo yesisombululo se-DNS ukuze ilahlekise abasebenzisi okanye iinkqubo. Izixhobo ezindala aziyi kulahleka.
