DDoS(I-Distributed Denial of Service) luhlobo lohlaselo lwe-cyber apho iikhomputha ezininzi eziphazamisekileyo okanye izixhobo zisetyenziselwa ukukhukula inkqubo ekujoliswe kuyo okanye inethiwekhi kunye nomthamo omkhulu we-traffic, ukugqithisa izibonelelo zayo kunye nokubangela ukuphazamiseka ekusebenzeni kwayo okuqhelekileyo. Injongo yohlaselo lwe-DDoS kukwenza inkqubo ekujoliswe kuyo okanye inethiwekhi ingafikeleleki kubasebenzisi abasemthethweni.
Nanga amanye amanqaku aphambili malunga nohlaselo lweDDoS:
1. Indlela yokuhlasela: Ukuhlaselwa kwe-DDoS ngokuqhelekileyo kubandakanya inani elikhulu lezixhobo, ezibizwa ngokuba yi-botnet, ezilawulwa ngumhlaseli. Ezi zixhobo zihlala zosulelwa yi-malware evumela umhlaseli ukuba alawule kude kwaye alungelelanise uhlaselo.
2. Iintlobo zoHlaselo lwe-DDoS: Uhlaselo lwe-DDoS lungathatha iindlela ezahlukeneyo, kubandakanywa uhlaselo lwe-volumetric olukhukula ekujoliswe kuyo ngokugqithiswa kwe-traffic, uhlaselo lwe-application layer olujolise kwizicelo ezithile okanye iinkonzo, kunye nokuhlaselwa kweprotocol okusebenzisa ubuthathaka kwiiprotocol zenethiwekhi.
3. Impembelelo: Ukuhlaselwa kwe-DDoS kunokuba nemiphumo emibi kakhulu, ekhokelela ekuphazamisekeni kwenkonzo, ixesha lokuphumla, ukulahlekelwa yimali, ukonakala kwegama, kunye namava omsebenzisi aphantsi. Zinokuchaphazela amaqumrhu ahlukeneyo, kubandakanywa iiwebhusayithi, iinkonzo ze-intanethi, amaqonga e-e-commerce, amaziko emali, kunye nothungelwano luphela.
4. Ukunciphisa: Imibutho isebenzisa iindlela ezahlukeneyo zokunciphisa i-DDoS ukukhusela iinkqubo zabo kunye nothungelwano. Oku kubandakanya ukuhluzwa kwetrafikhi, ukunciphisa izinga, ukubhaqwa okungaqhelekanga, ukuphambukiswa kwetrafikhi, kunye nokusetyenziswa kwehardware ekhethekileyo okanye izisombululo zesoftware eyenzelwe ukuchonga nokunciphisa uhlaselo lweDDoS.
5. Uthintelo: Ukuthintela uhlaselo lwe-DDoS kufuna indlela esebenzayo ebandakanya ukuphumeza amanyathelo okhuseleko oluluqilima lwenethiwekhi, ukwenza uvavanyo oluqhelekileyo lokuba semngciphekweni, ukuchwetheza ubuthathaka besoftware, kunye nezicwangciso zokuphendula isiganeko endaweni yokujongana nokuhlaselwa ngokufanelekileyo.
Kubalulekile ukuba imibutho ihlale iphaphile kwaye ilungele ukuphendula kuhlaselo lwe-DDoS, njengoko inokuba nempembelelo enkulu kwimisebenzi yeshishini kunye nokuthembela kwabathengi.
Uhlaselo lwe-Anti-DDoS yoKhuselo
1. Hlunga iinkonzo ezingeyomfuneko kunye namazibuko
I-Inexpress, i-Express, i-Forwarding kunye nezinye izixhobo zingasetyenziselwa ukucoca iinkonzo ezingeyomfuneko kunye namachweba, oko kukuthi, ukucoca i-ip fake kwi-router.
2. Ukucoca kunye nokuhluzwa kokuhamba okungaqhelekanga
Ukucoca kunye nokucoca i-traffic engaqhelekanga ngokusebenzisa i-firewall ye-DDoS ye-hardware, kwaye usebenzise itekhnoloji yezinga eliphezulu ezifana nokuhluza umthetho wepakethi yedatha, ukuhamba kwedatha ukukhangela ukukhangela iminwe, kunye nokucoca umxholo wepakethi yedatha ukucacisa ngokuchanekileyo ukuba i-traffic yokufikelela yangaphandle iyinto eqhelekileyo, kwaye ukuvimbela ngakumbi ukuhluzwa kwe-traffic engaqhelekanga.
3. Ukhuselo lweqela elisasaziweyo
Le ngoku yeyona ndlela isebenzayo yokukhusela uluntu lwe-cybersecurity kuhlaselo olukhulu lweDDoS. Ukuba i-node ihlaselwe kwaye ayikwazi ukubonelela ngeenkonzo, inkqubo iya kutshintshela ngokuzenzekelayo kwenye i-node ngokuhambelana nokumisela okuphambili, kwaye ibuyisele zonke iipakethi zedatha zomhlaseli kwindawo yokuthumela, ukukhubazeka komthombo wokuhlaselwa kunye nokuchaphazela ishishini ukusuka kwimbono enzulu yokukhusela ukhuseleko kwizigqibo zokuphunyezwa kokhuseleko.
4. Uhlalutyo oluphezulu lwe-DNS olukhuselekileyo
Indibaniselwano egqibeleleyo yenkqubo yesisombululo se-DNS ekrelekrele kunye nenkqubo yokhuselo ye-DDoS ibonelela ngamashishini anobuchule obuphezulu bokubona izoyikiso zokhuseleko ezivelayo. Ngelo xesha, kukho umsebenzi wokufumanisa ukuvala, onokukhubaza i-intelligence ye-IP ye-server nanini na ukuba ithathe indawo ye-IP ye-server eqhelekileyo, ukwenzela ukuba inethiwekhi yezoshishino ikwazi ukugcina i-service service never-stop.
Uhlaselo lwe-Anti DDoS lweBhanki yezeMali yoKhuseleko loLawulo lweZithuthi, ukuFumana nokuCoca:
1. Impendulo ye-Nanosecond, ngokukhawuleza kwaye ichanekile.Imodeli yoshishino lwetrafikhi yokuzifundela kunye nepakethi ngepakethi yokufumanisa ubunzulu beteknoloji yamkelwa. Emva kokuba i-traffic engaqhelekanga kunye nomyalezo ufunyenwe, isicwangciso sokukhusela ngokukhawuleza siqaliswa ukuqinisekisa ukuba ukulibaziseka phakathi kokuhlaselwa kunye nokukhusela kungaphantsi kwemizuzwana ye-2. Kwangaxeshanye, isisombululo sococeko esingaqhelekanga esisekwe kwiileyile zokucoca uloliwe wengcinga, ngokusebenzisa iileyibhile ezisixhenxe zokuhlalutywa kocazululo, ukusuka kwigama le-IP, umaleko wezothutho kunye nomgangatho wesicelo, ukuqaphela uphawu, iseshoni kwimiba esixhenxe, ukuziphatha kwenethiwekhi, ukubunjwa kwetrafikhi ukuthintela ukuchongwa kokucoca inyathelo ngenyathelo, ukuphucula ukusebenza ngokupheleleyo kokhuselo, isiqinisekiso esisebenzayo seziko ledatha yebhanki yeXXX.
2. Ukwahlulwa kokuhlolwa nokulawula, okusebenzayo nokuthembekileyo. Iskimu sokusasazwa esahlukileyo seziko lovavanyo kunye neziko lokucoca linokuqinisekisa ukuba iziko lovavanyo lingaqhubeka nokusebenza emva kokungaphumeleli kweziko lokucoca, kwaye livelise ingxelo yovavanyo kunye nesaziso se-alarm ngexesha langempela, elingabonisa ukuhlaselwa kwebhanki ye-XXX ukuya kumlinganiselo omkhulu.
3. Ulawulo oluguquguqukayo, ukwanda kokukhathazeka.Isisombululo se-Anti-ddos sinokukhetha iindlela ezintathu zokulawula: ukufumanisa ngaphandle kokucoca, ukufumanisa ngokuzenzekelayo kunye nokukhuselwa kokucoca, kunye nokukhusela okusebenzisanayo okusebenzayo.Ukusetyenziswa okuguquguqukayo kweendlela ezintathu zokulawula kunokuhlangabezana neemfuno zoshishino lwe-XXX yebhanki ukunciphisa umngcipheko wokuphunyezwa kunye nokuphucula ukufumaneka xa ishishini elitsha liqaliswa.
Ixabiso loMthengi
1. Sebenzisa ngempumelelo i-network bandwidth ukuphucula izibonelelo zeshishini
Ngesisombululo sokhuseleko jikelele, ingozi yokhuseleko lwenethiwekhi ebangelwa ukuhlaselwa kwe-DDoS kwishishini le-intanethi kwiziko layo ledatha laliyi-0, kwaye inkunkuma ye-intanethi ye-outlet bandwidth ebangelwa yi-traffic engavumelekanga kunye nokusetyenziswa kwemithombo yomncedisi yancitshiswa, eyadala iimeko ze-XXX yebhanki ukuphucula izibonelelo zayo.
2. Ukunciphisa iMingcipheko, qinisekisa uzinzo lothungelwano kunye nokuzinza koshishino
Ukuthunyelwa kwe-bypass yezixhobo ezichasene ne-ddos ayitshintshi i-architecture yenethiwekhi ekhoyo, akukho mngcipheko we-cutover yenethiwekhi, akukho nqaku elilodwa lokungaphumeleli, akukho mpembelelo ekusebenzeni okuqhelekileyo kweshishini, kunye nokunciphisa iindleko zokuphunyezwa kunye neendleko zokusebenza.
3. Ukuphucula ukwaneliseka kwabasebenzisi, ukudibanisa abasebenzisi abakhoyo kunye nokuphuhlisa abasebenzisi abatsha
Ukubonelela abasebenzisi ngobume bothungelwano lokwenyani, ibhanki ye-intanethi, imibuzo yoshishino lwe-intanethi kunye nolwaneliseko lwabasebenzisi be-intanethi luphuculwe kakhulu, ludibanise ukunyaniseka komsebenzisi, ukubonelela abathengi ngeenkonzo zokwenyani.
