I-DDoS(Distributed Denial of Service) uhlobo lokuhlasela kwe-inthanethi lapho amakhompyutha noma amadivayisi amaningi asengozini esetshenziswa ukugcwala uhlelo noma inethiwekhi eqondiwe ngethrafikhi enkulu, kugcwale izinsiza zayo futhi kubangele ukuphazamiseka ekusebenzeni kwayo okuvamile. Inhloso yokuhlasela kwe-DDoS ukwenza uhlelo noma inethiwekhi eqondiwe ingafinyeleleki kubasebenzisi abasemthethweni.
Nazi ezinye izinto ezibalulekile mayelana nokuhlaselwa kwe-DDoS:
1. Indlela Yokuhlasela: Ukuhlaselwa kwe-DDoS kuvame ukuhilela inani elikhulu lamadivayisi, aziwa ngokuthi i-botnet, alawulwa umhlaseli. Lawa madivayisi avame ukungenwa yi-malware evumela umhlaseli ukulawula nokuxhumanisa ukuhlaselwa kude.
2. Izinhlobo Zokuhlaselwa kwe-DDoS: Ukuhlaselwa kwe-DDoS kungathatha izinhlobo ezahlukene, kufaka phakathi ukuhlaselwa kwevolumu okugcwala okuqondiswe ekuqondisweni ngethrafikhi eningi, ukuhlaselwa kwezendlalelo zohlelo lokusebenza okuqondiswe kuzinhlelo zokusebenza noma izinsizakalo ezithile, kanye nokuhlaselwa kwephrothokholi okuxhaphaza ubuthakathaka kumaphrothokholi enethiwekhi.
3. Umthelela: Ukuhlaselwa kwe-DDoS kungaba nemiphumela emibi kakhulu, okuholela ekuphazamisekeni kwesevisi, isikhathi sokungasebenzi, ukulahlekelwa yizimali, ukulimala kwedumela, kanye nokuhlangenwe nakho komsebenzisi okusengozini. Kungathinta izinhlangano ezahlukahlukene, kufaka phakathi amawebhusayithi, izinsizakalo eziku-inthanethi, amapulatifomu e-commerce, izikhungo zezimali, kanye namanethiwekhi aphelele.
4. Ukunciphisa: Izinhlangano zisebenzisa amasu ahlukahlukene okunciphisa i-DDoS ukuvikela izinhlelo zazo namanethiwekhi. Lokhu kufaka phakathi ukuhlunga ithrafikhi, ukukhawulela amazinga, ukutholakala kwezinkinga, ukuphambukisa ithrafikhi, kanye nokusetshenziswa kwezixazululo ezikhethekile zehadiwe noma zesofthiwe ezenzelwe ukuhlonza nokunciphisa ukuhlaselwa kwe-DDoS.
5. UkuvimbelaUkuvimbela ukuhlaselwa kwe-DDoS kudinga indlela yokuthatha isinyathelo ehilela ukusebenzisa izinyathelo zokuphepha zenethiwekhi eziqinile, ukwenza ukuhlolwa kobungozi njalo, ukulungisa ubuthakathaka besofthiwe, kanye nokuba nezinhlelo zokuphendula ezigamekweni ukuze kusingathwe ukuhlaselwa ngempumelelo.
Kubalulekile ukuthi izinhlangano zihlale ziqaphile futhi zilungele ukuphendula ekuhlaselweni kwe-DDoS, njengoba kungaba nomthelela omkhulu ekusebenzeni kwebhizinisi kanye nokwethenjwa kwamakhasimende.
Ukuhlasela kwe-Defense Anti-DDoS
1. Hlunga izinsizakalo ezingadingekile kanye namachweba
Amathuluzi e-Inexpress, Express, Forwarding kanye namanye angasetshenziswa ukuhlunga izinsizakalo ezingadingekile kanye nama-port, okungukuthi, ukuhlunga i-ip fake ku-router.
2. Ukuhlanza nokuhlunga ukugeleza okungavamile
Hlanza futhi uhlunge ithrafikhi engajwayelekile nge-firewall yehadiwe ye-DDoS, bese usebenzisa ubuchwepheshe obusezingeni eliphezulu njengokuhlunga imithetho yephakethe ledatha, ukuhlunga ukugeleza kwedatha, kanye nokuhlunga ngokwezifiso okuqukethwe kwephakethe ledatha ukuze kunqunywe ngokunembile ukuthi ithrafikhi yokufinyelela yangaphandle ivamile yini, futhi kuvinjelwe nokuhlunga ithrafikhi engajwayelekile.
3. Ukuzivikela kweqembu okusatshalalisiwe
Lena yindlela ephumelela kakhulu yokuvikela umphakathi wezokuphepha kwe-inthanethi ekuhlaselweni okukhulu kwe-DDoS. Uma i-node ihlaselwa futhi ingakwazi ukunikeza izinsizakalo, uhlelo luzoshintshela kwenye i-node ngokuzenzakalelayo ngokuya ngesethingi yokuqala, bese lubuyisela wonke amaphakethe edatha omhlaseli endaweni yokuthumela, okuphazamisa umthombo wokuhlaselwa futhi kuthinte ibhizinisi kusukela ekubukeni okujulile kokuvikelwa kokuphepha izinqumo zokusebenzisa ukuphepha.
4. Ukuhlaziywa kwe-DNS okuhlakaniphile okuphezulu kokuphepha
Inhlanganisela ephelele yesistimu yokuxazulula i-DNS ehlakaniphile kanye nesistimu yokuvikela ye-DDoS inikeza amabhizinisi amakhono okuthola angcono kakhulu ezinsongweni zokuphepha ezivelayo. Ngesikhathi esifanayo, kukhona nomsebenzi wokuthola ukuvala, ongakhubaza ubuhlakani be-IP yeseva nganoma yisiphi isikhathi ukuze kuthathelwe indawo i-IP yeseva evamile, ukuze inethiwekhi yebhizinisi ikwazi ukugcina isimo sesevisi esingapheli.
Ukuhlaselwa kwe-Anti DDoS kokuphepha kwenethiwekhi yezezimali yasebhange Ukuphatha, Ukuthola kanye nokuhlanza ithrafikhi:
1. Impendulo ye-Nanosecond, esheshayo nenembile. Ukuzifundela kwethrafikhi yemodeli yebhizinisi kanye nephakethe ngobuchwepheshe bokuthola ukujula kwephakethe kuyasetshenziswa. Uma sekutholakale ithrafikhi engajwayelekile kanye nomyalezo, isu lokuvikela elisheshayo liyaqaliswa ukuqinisekisa ukuthi ukubambezeleka phakathi kokuhlasela nokuzivikela kungaphansi kwemizuzwana emi-2. Ngesikhathi esifanayo, ikhambi lokuhlanza ukugeleza okungajwayelekile elisekelwe ezingqimbeni zomcabango wokuhlanza isihlungi, ngokusebenzisa izingqimba eziyisikhombisa zokucubungula ukuhlaziywa kokugeleza, kusukela edumeleni le-IP, ungqimba lokuthutha kanye nongqimba lwesicelo, ukuqashelwa kwesici, iseshini ezicini eziyisikhombisa, ukuziphatha kwenethiwekhi, ukwakheka kwethrafikhi ukuvimbela ukuhlunga ukuhlonza isinyathelo ngesinyathelo, ukuthuthukisa ukusebenza okuphelele kokuzivikela, isiqinisekiso esisebenzayo sokuphepha kwenethiwekhi yesikhungo sedatha sasebhange i-XXX.
2. Ukuhlukaniswa kokuhlolwa nokulawula, okusebenzayo nokuthembekile. Uhlelo oluhlukile lokufakwa kwesikhungo sokuhlola kanye nesikhungo sokuhlanza lungaqinisekisa ukuthi isikhungo sokuhlola singaqhubeka nokusebenza ngemva kokwehluleka kwesikhungo sokuhlanza, futhi sikhiqize umbiko wokuhlola kanye nesaziso se-alamu ngesikhathi sangempela, okungabonisa ukuhlaselwa kwebhange le-XXX ngezinga elikhulu.
3. Ukuphathwa okuguquguqukayo, ukukhulisa okungenazinkathazo. Isixazululo se-Anti-ddos singakhetha izindlela ezintathu zokuphatha: ukutholwa ngaphandle kokuhlanza, ukuvikelwa kokutholwa okuzenzakalelayo nokuhlanza, kanye nokuvikelwa kokusebenzisana ngesandla. Ukusetshenziswa okuguquguqukayo kwezindlela ezintathu zokuphatha kungahlangabezana nezidingo zebhizinisi zebhange le-XXX ukunciphisa ingozi yokuqaliswa nokuthuthukisa ukutholakala lapho ibhizinisi elisha liqaliswa.
Inani Lekhasimende
1. Sebenzisa kahle i-bandwidth yenethiwekhi ukuthuthukisa izinzuzo zebhizinisi
Ngesixazululo sokuphepha esiphelele, ingozi yokuphepha kwenethiwekhi ebangelwe ukuhlaselwa kwe-DDoS ebhizinisini eliku-inthanethi lesikhungo sayo sedatha yayingu-0, kanti ukuchitheka komkhawulokudonsa wenethiwekhi okubangelwa yithrafikhi engavumelekile kanye nokusetshenziswa kwezinsiza zeseva kwancishiswa, okwadala izimo zebhange le-XXX zokuthuthukisa izinzuzo zalo.
2. Nciphisa Izingozi, qinisekisa ukuzinza kwenethiwekhi kanye nokusimama kwebhizinisi
Ukufakwa kwemishini yokulwa ne-ddos ngendlela edlulayo akushintshi ukwakheka kwenethiwekhi okukhona, akukho bungozi bokunqamuka kwenethiwekhi, akukho phuzu elilodwa lokwehluleka, akukho mthelela ekusebenzeni okuvamile kwebhizinisi, futhi kunciphisa izindleko zokuqalisa kanye nezindleko zokusebenza.
3. Thuthukisa ukwaneliseka komsebenzisi, ukuhlanganisa abasebenzisi abakhona kanye nokuthuthukisa abasebenzisi abasha
Ukunikeza abasebenzisi indawo yangempela yenethiwekhi, ukubhanga online, imibuzo yebhizinisi online kanye nokunye ukwaneliseka kwabasebenzisi bebhizinisi online kuthuthukisiwe kakhulu, qinisa ukwethembeka kwabasebenzisi, ukuze kuhlinzekwe amakhasimende ngezinsizakalo zangempela.
