I-DDoS(I-Distributed Denial of Service) iwuhlobo lokuhlasela ku-inthanethi lapho amakhompuyutha amaningi onakalisiwe noma amathuluzi asetshenziswa ukuze kukhukhule isistimu eqondiwe noma inethiwekhi enomthamo omkhulu wethrafikhi, eqeda izinsiza zayo futhi ibangele ukuphazamiseka ekusebenzeni kwayo okuvamile.Inhloso yokuhlasela kwe-DDoS ukwenza isistimu eqondiwe noma inethiwekhi ingafinyeleleki kubasebenzisi abasemthethweni.
Nawa amaphuzu abalulekile mayelana nokuhlaselwa kwe-DDoS:
1. Indlela Yokuhlasela: Ukuhlasela kwe-DDoS kuvame ukubandakanya inombolo enkulu yamadivayisi, aziwa njenge-botnet, alawulwa umhlaseli.Lawa madivayisi avame ukungenwa i-malware evumela umhlaseli ukuthi alawule kude futhi axhumanise ukuhlasela.
2. Izinhlobo Zokuhlasela kwe-DDoS: Ukuhlasela kwe-DDoS kungathatha izinhlobo ezihlukene, okuhlanganisa ukuhlasela kwevolumu egcwele okuqondiwe ngethrafikhi eningi, ukuhlasela kwesendlalelo sohlelo lokusebenza okuqondise izinhlelo zokusebenza ezithile noma amasevisi, nokuhlasela kwephrothokholi okusebenzisa ubungozi kuzivumelwano zenethiwekhi.
3. Umthelela: Ukuhlaselwa kwe-DDoS kungaba nemiphumela emibi kakhulu, okuholela ekuphazanyisweni kwesevisi, isikhathi sokuphumula, ukulahlekelwa kwezimali, ukonakala kwesithunzi, kanye nolwazi lomsebenzisi olungena engozini.Zingathinta izinhlangano ezahlukahlukene, okuhlanganisa amawebhusayithi, izinsiza ze-inthanethi, izinkundla ze-e-commerce, izikhungo zezezimali, kanye namanethiwekhi wonke.
4. Ukunciphisa: Izinhlangano zisebenzisa amasu okunciphisa e-DDoS ahlukahlukene ukuze zivikele amasistimu namanethiwekhi azo.Lokhu kufaka phakathi ukuhlungwa kwethrafikhi, ukukhawulela izinga, ukutholwa okudidayo, ukuphambukiswa kwethrafikhi, kanye nokusetshenziswa kwezingxenyekazi zekhompuyutha ezikhethekile noma izixazululo zesofthiwe eziklanyelwe ukuhlonza nokunciphisa ukuhlaselwa kwe-DDoS.
5. Ukuvimbela: Ukuvimbela ukuhlaselwa kwe-DDoS kudinga indlela esheshayo ehilela ukusebenzisa izinyathelo zokuphepha zenethiwekhi eziqinile, ukwenza ukuhlolwa okujwayelekile kokuba sengozini, ukuchibiyela ubungozi besofthiwe, nokuba nezinhlelo zokuphendula isigameko ukuze kusingathwe ukuhlasela ngempumelelo.
Kubalulekile ukuthi izinhlangano zihlale ziqaphile futhi zilungele ukuphendula ekuhlaselweni kwe-DDoS, njengoba kungase kube nomthelela omkhulu ekusebenzeni kwebhizinisi nokwethenjwa kwamakhasimende.
Ukuhlasela kwe-Defense Anti-DDoS
1. Hlunga amasevisi namachweba angadingekile
I-Inexpress, Express, Forwarding namanye amathuluzi angasetshenziswa ukuhlunga izinsiza ezingadingekile namachweba, okusho ukuthi, ukuhlunga i-ip mbumbulu kumzila.
2. Ukuhlanza nokuhlunga ukugeleza okungavamile
Hlanza futhi uhlunge ithrafikhi engavamile ngokusebenzisa i-firewall yehadiwe ye-DDoS, futhi usebenzise ubuchwepheshe bezinga eliphezulu njengokuhlunga umthetho wephakethe ledatha, ukuhlunga kokutholwa kwezigxivizo zeminwe, nokuhlunga ngokwezifiso okuqukethwe kwephakethe ledatha ukuze unqume ngokunembile ukuthi ithrafikhi yokufinyelela yangaphandle ijwayelekile yini, futhi uvimbele ukuhlunga. yethrafikhi engavamile.
3. Ukuvikela iqoqo elisabalalisiwe
Lokhu okwamanje kuyindlela ephumelela kakhulu yokuvikela umphakathi we-cybersecurity ekuhlaselweni okukhulu kwe-DDoS.Uma i-node ihlaselwa futhi ingakwazi ukunikeza izinsizakalo, isistimu izoshintshela kwenye i-node ngokuzenzakalelayo ngokuya ngokulungiselelwa okubalulekile, futhi ibuyisele wonke amaphakethe edatha yomhlaseli endaweni yokuthumela, ikhubaze umthombo wokuhlasela futhi ithinte ibhizinisi kusukela ekuvikelekeni okujulile. izinqumo zokusebenzisa ukuphepha kombono wokuvikela.
4. Ukuhlaziywa kwe-DNS ehlakaniphile yokuphepha okuphezulu
Inhlanganisela ephelele yesistimu yokuxazulula ye-DNS ehlakaniphile kanye nesistimu yokuvikela ye-DDoS ihlinzeka amabhizinisi ngamakhono amakhulu okuthola izinsongo zokuphepha ezivelayo.Ngesikhathi esifanayo, kukhona nomsebenzi wokuthola ukuvala shaqa, ongakhubaza ubuhlakani be-IP yeseva nganoma yisiphi isikhathi ukuze ubuyisele i-IP yeseva evamile, ukuze inethiwekhi yebhizinisi ikwazi ukugcina isimo sesevisi esingalokothi sime.
Ukuhlasela kwe-Anti DDoS Yokuphathwa Kwethrafikhi Yenethiwekhi Yezezimali Yebhange, Ukutholwa Nokuhlanza:
1. Impendulo ye-Nanosecond, iyashesha futhi inembile.Ukuzifundela kwethrafikhi yemodeli yebhizinisi kanye nephakethe lobuchwepheshe bokubona ukujula kwephakethe kuyamukelwa.Uma ithrafikhi engavamile nomlayezo sekutholakele, isu lokuvikela elisheshayo liyaqaliswa ukuze kuqinisekiswe ukuthi ukubambezeleka phakathi kokuhlasela nokuzivikela kungaphansi kwamasekhondi angu-2.Ngesikhathi esifanayo, isisombululo sokuhlanza ukugeleza okungavamile okusekelwe ezingxenyeni zesitimela sokuhlanza isihlungi somcabango, ngokusebenzisa izingqimba eziyisikhombisa zokucubungula ukugeleza kokucubungula, kusukela esidumeni se-IP, isendlalelo sezokuthutha kanye nosendlalelo sesicelo, ukuqashelwa kwesici, iseshini ezicini eziyisikhombisa, inethiwekhi. ukuziphatha, ukwakheka kwethrafikhi ukuvimbela ukuhlunga ukuhlonza isinyathelo ngesinyathelo, ukuthuthukisa ukusebenza kukonke kwezokuvikela, isiqinisekiso esisebenzayo sokuvikeleka kwenethiwekhi yesikhungo sedatha sebhange le-XXX.
2. Ukuhlukaniswa kokuhlolwa nokulawula, okusebenzayo nokuthembekile.Uhlelo oluhlukile lokuthunyelwa kwesikhungo sokuhlola kanye nesikhungo sokuhlanza singaqinisekisa ukuthi isikhungo sokuhlola singaqhubeka nokusebenza ngemva kokuhluleka kwesikhungo sokuhlanza, futhi sikhiqize umbiko wokuhlola kanye nesaziso se-alamu ngesikhathi sangempela, esingabonisa ukuhlasela kwebhange le-XXX. ngezinga elikhulu.
3. Ukuphatha okuguquguqukayo, ukunwetshwa okungakhathazeki.Isixazululo se-Anti-ddos singakhetha izindlela zokuphatha ezintathu: ukutholwa ngaphandle kokuhlanza, ukutholwa okuzenzakalelayo nokuvikela ukuhlanza, nokuvikela okusebenzisanayo okwenziwa ngesandla.Ukusetshenziswa okuguquguqukayo kwezindlela zokuphatha ezintathu kungahlangabezana nezidingo zebhizinisi ze-XXX ibhange ukunciphisa ubungozi bokuqalisa kanye nokwenza ngcono ukutholakala lapho ibhizinisi elisha lethulwa.
Inani Lekhasimende
1. Sebenzisa ngempumelelo i-bandwidth yenethiwekhi ukuze uthuthukise izinzuzo zebhizinisi
Ngesixazululo sezokuphepha sisonke, ingozi yezokuphepha yenethiwekhi edalwe ukuhlaselwa kwe-DDoS ebhizinisini eliku-inthanethi lesikhungo sayo sedatha kwaba ngu-0, nokumoshakala komkhawulokudonsa wenethiwekhi okubangelwa ithrafikhi engavumelekile kanye nokusetshenziswa kwezinsiza zeseva kwehliswa, okudale izimo ze-XXX. ibhange ukuthuthukisa izinzuzo zalo.
2. Yehlisa Izingozi, uqinisekise ukuzinza kwenethiwekhi kanye nokusimama kwebhizinisi
Ukuthunyelwa kwe-bypass kwemishini ye-anti-ddos akushintshi isakhiwo senethiwekhi esikhona, akukho bungozi bokunqamuka kwenethiwekhi, akukho iphuzu elilodwa lokwehluleka, akukho nomthelela ekusebenzeni okuvamile kwebhizinisi, futhi kunciphisa izindleko zokuqalisa kanye nezindleko zokusebenza.
3. Thuthukisa ukwaneliseka kwabasebenzisi, hlanganisa abasebenzisi abakhona futhi uthuthukise abasebenzisi abasha
Ukuhlinzeka abasebenzisi ngendawo yenethiwekhi yangempela, ukubhanga ku-inthanethi, imibuzo yebhizinisi eku-inthanethi nokunye ukwaneliseka kwabasebenzisi bebhizinisi abaku-inthanethi kuthuthukiswe kakhulu, kuhlanganiswe ukwethembeka kwabasebenzisi, ukuze kuhlinzekwe amakhasimende ngezinsizakalo zangempela.
