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
Coca kwaye ucofe i-traffic engaqhelekanga nge-firewall ye-DDoS ye-hardware, kwaye usebenzise itekhnoloji ekumgangatho ophezulu njengokucoca umthetho wepakethi yedatha, ukuhamba kwedatha ukucofa ukukhangela iminwe, kunye nokucoca umxholo wepakethi yedatha ukujonga ngokuchanekileyo ukuba i-traffic yokufikelela yangaphandle iqhelekile, kwaye ukwalela ukucoca. yetrafikhi 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, ikhubaze umthombo wokuhlaselwa kwaye ichaphazele ishishini ukusuka kukhuseleko olunzulu. imbono yokhuseleko izigqibo 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. Ngexesha elifanayo, isisombululo sokucoca ukuhamba okungaqhelekanga okusekelwe kwiingqimba zokucoca isitimela sokucoca ingcamango, ngokusebenzisa iileyile ezisixhenxe zokuhlalutya uhlalutyo lokuhamba, ukusuka kwigama le-IP, umgca wezothutho kunye noluhlu lwesicelo, ukuqaphela uphawu, iseshoni kwiinkalo ezisixhenxe, inethiwekhi. ukuziphatha, ukubunjwa kwetrafikhi ukuthintela ukuchongwa kokucoca inyathelo ngenyathelo, ukuphucula ukusebenza ngokubanzi kokhuselo, isiqinisekiso esisebenzayo se-XXX yedatha yeziko ledatha yedatha yokhuseleko womnatha.
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-alamu ngexesha langempela, elingabonisa ukuhlaselwa kwebhanki ye-XXX. ukusa kumlinganiselo omkhulu.
3. Ulawulo oluguquguqukayo, ulwandiso olungenaxhala.Isisombululo se-Anti-ddos singakhetha iindlela ezintathu zokulawula: ukufumanisa ngaphandle kokucoca, ukufumanisa ngokuzenzekelayo kunye nokukhuselwa kokucoca, kunye nokukhusela okusebenzayo okusebenzayo.Ukusetyenziswa okuguquguqukayo kweendlela ezintathu zokulawula kunokuhlangabezana neemfuno zoshishino lweXXX ibhanki ukunciphisa ukuphunyezwa komngcipheko kunye nokuphucula ukufumaneka xa kuqalwa ishishini elitsha.
Ixabiso loMthengi
1. Sebenzisa ngempumelelo i-network bandwidth ukuphucula izibonelelo zeshishini
Ngesisombululo esipheleleyo sokhuseleko, ingozi yokhuseleko lwenethiwekhi ebangelwa ukuhlaselwa kwe-DDoS kwishishini le-intanethi yedatha yedatha yayiyi-0, kunye nenkcitho ye-intanethi ye-intanethi ye-bandwidth ebangelwa yi-traffic engavumelekanga kunye nokusetyenziswa kwemithombo yomncedisi yancitshiswa, eyadala iimeko ze-XXX. ibhanki 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.
