I-DDoS(Distributed Denial of Service) luhlobo lohlaselo lwe-intanethi apho iikhompyutha okanye izixhobo ezininzi ezisengozini zisetyenziselwa ukugubungela inkqubo okanye inethiwekhi ejoliswe kuyo ngobuninzi betrafikhi, zigqithise izixhobo zayo kwaye zibangele ukuphazamiseka ekusebenzeni kwayo okuqhelekileyo. Injongo yohlaselo lwe-DDoS kukwenza inkqubo okanye inethiwekhi ejoliswe kuyo ingafikeleleki kubasebenzisi abasemthethweni.
Nazi ezinye iingongoma ezibalulekileyo malunga nokuhlaselwa kwe-DDoS:
1. Indlela yokuhlaselaUhlaselo lwe-DDoS ludla ngokubandakanya inani elikhulu lezixhobo, ezaziwa ngokuba yi-botnet, ezilawulwa ngumhlaseli. Ezi zixhobo zihlala zosulelwa yi-malware evumela umhlaseli ukuba alawule kude aze alungelelanise uhlaselo.
2. Iintlobo zoHlaselo lwe-DDoSUhlaselo lwe-DDoS lunokuthatha iindlela ezahlukeneyo, kubandakanya uhlaselo olunamandla oluzalisa ithagethi ngethrafikhi egqithisileyo, uhlaselo lwe-application layer olujolise kwizicelo okanye iinkonzo ezithile, kunye nohlaselo lwe-protocol olusebenzisa ubuthathaka kwiiprotokholi zenethiwekhi.
3. Impembelelo: Uhlaselo lwe-DDoS lunokuba nemiphumo emibi kakhulu, ekhokelela ekuphazamisekeni kwenkonzo, ixesha lokungasebenzi, ilahleko zemali, umonakalo wegama, kunye namava omsebenzisi asengozini. Zinokuchaphazela amaziko ahlukeneyo, kuquka iiwebhusayithi, iinkonzo ze-intanethi, amaqonga e-e-commerce, amaziko emali, kwaneenethiwekhi ziphela.
4. Ukunciphisa: Imibutho isebenzisa iindlela ezahlukeneyo zokunciphisa i-DDoS ukukhusela iinkqubo zayo kunye neenethiwekhi. Ezi ziquka ukuhluzwa kwethrafikhi, ukunciphisa amaxabiso, ukubhaqwa kwezinto ezingaqhelekanga, ukuphambuka kwethrafikhi, kunye nokusetyenziswa kwezisombululo zehardware okanye zesoftware ezikhethekileyo ezenzelwe ukuchonga nokunciphisa uhlaselo lwe-DDoS.
5. UthinteloUkuthintela uhlaselo lwe-DDoS kufuna indlela esebenzayo equka ukuphumeza amanyathelo okhuseleko oluqinileyo lwenethiwekhi, ukwenza uvavanyo lobuthathaka rhoqo, ukulungisa ubuthathaka besoftware, kunye nokuba nezicwangciso zokuphendula kwiziganeko ukuze kusingathwe uhlaselo ngokufanelekileyo.
Kubalulekile ukuba imibutho ihlale iphaphile kwaye ilungele ukuphendula kuhlaselo lwe-DDoS, njengoko lunokuba nefuthe elikhulu kwimisebenzi yeshishini kunye nokuthenjwa kwabathengi.
Uhlaselo lwe-Anti-DDoS loKhuselo
1. Hlunga iinkonzo kunye namazibuko angafunekiyo
Izixhobo ze-Inexpress, Express, Forwarding kunye nezinye zingasetyenziselwa ukucoca iinkonzo ezingafunekiyo kunye neeports, oko kukuthi, ukucoca i-ip yobuxoki kwi-router.
2. Ukucoca kunye nokucoca ukuhamba okungaqhelekanga
Coca kwaye uhluze ithrafikhi engaqhelekanga nge-firewall yehadiwe ye-DDoS, kwaye usebenzise ubuchwepheshe obuphezulu obufana nokucoca imithetho yephakethi yedatha, ukucoca ukufunyaniswa kweminwe yokuhamba kwedatha, kunye nokucoca umxholo wephakethi yedatha ukuze umisele ngokuchanekileyo ukuba ithrafikhi yokufikelela yangaphandle iqhelekile na, kwaye uthintele ngakumbi ukuhluza ithrafikhi engaqhelekanga.
3. Ukhuselo lweqela olusasazekileyo
Le yeyona ndlela isebenzayo ngoku yokukhusela uluntu lokhuseleko lwe-cyber kwiintlaselo ezinkulu ze-DDoS. Ukuba i-node ihlaselwa kwaye ayinakubonelela ngeenkonzo, inkqubo iya kutshintshela kwenye i-node ngokuzenzekelayo ngokwendlela ebekwe ngayo kuqala, kwaye ibuyisele zonke iipakethi zedatha zomhlaseli kwindawo yokuthumela, nto leyo ephazamisa umthombo wohlaselo kwaye ichaphazele ishishini ngokwembono yokhuseleko olunzulu izigqibo zokuphunyezwa kokhuseleko.
4. Uhlalutyo lwe-DNS olukrelekrele kakhulu lokhuseleko
Indibaniselwano egqibeleleyo yenkqubo yokusombulula i-DNS ekrelekrele kunye nenkqubo yokuzikhusela ye-DDoS inika amashishini amandla okufumanisa angcono kwiingozi zokhuseleko ezivelayo. Kwangaxeshanye, kukwakho nomsebenzi wokufumanisa ukuvala, onokukhubaza ubukrelekrele be-server IP nangaliphi na ixesha ukuze kuthathelwe indawo i-IP yeseva eqhelekileyo, ukuze inethiwekhi yeshishini ikwazi ukugcina imeko yenkonzo engayekiyo.
Uhlaselo lwe-Anti DDoS loKhuseleko lweNethiwekhi yezeMali yeBhanki Ukulawula, ukuFumanisa kunye nokucoca iTrafikhi:
1. Impendulo ye-Nanosecond, ekhawulezayo nechanekileyo. Ukuzifundela ngokwakho kwetrafikhi yemodeli yeshishini kunye nepakethi ngetekhnoloji yokufumanisa ubunzulu bepakethi kuyasetyenziswa. Nje ukuba itrafikhi engaqhelekanga kunye nemiyalezo zifunyenwe, icebo lokukhusela ngokukhawuleza liyaqaliswa ukuqinisekisa ukuba ukulibaziseka phakathi kohlaselo kunye nokuzikhusela kungaphantsi kwemizuzwana emi-2. Kwangaxeshanye, isisombululo sokucoca ukuhamba okungaqhelekanga esisekelwe kwiileya zomzila wengcinga yokucoca isihluzo, ngokusebenzisa iileya ezisixhenxe zokucubungula uhlalutyo lokuhamba, ukusuka kudumo lwe-IP, umaleko wokuthutha kunye nomaleko wesicelo, ukuqatshelwa kweempawu, iseshoni kwiinkalo ezisixhenxe, ukuziphatha kwenethiwekhi, ukubumba itrafikhi ukuthintela ukuhluzwa kokuchongwa inyathelo ngenyathelo, ukuphucula ukusebenza ngokubanzi kokhuselo, isiqinisekiso esisebenzayo sokhuseleko lwenethiwekhi yeziko ledatha lebhanki le-XXX.
2. Ukwahlulwa kokuhlolwa nolawulo, okusebenzayo nokuthembekileyo. Inkqubo eyahlukileyo yokusasazwa kweziko lovavanyo kunye neziko lokucoca inokuqinisekisa ukuba iziko lovavanyo linokuqhubeka nokusebenza emva kokusilela kweziko lokucoca, kwaye livelise ingxelo yovavanyo kunye nesaziso se-alamu ngexesha langempela, esinokubonisa uhlaselo lwebhanki ye-XXX ngokubanzi.
3. Ulawulo oluguquguqukayo, ulwandiso olungenaxhala. Isisombululo se-Anti-ddos sinokukhetha iindlela ezintathu zolawulo: ukufumanisa ngaphandle kokucoca, ukhuseleko lokuchonga ngokuzenzekelayo kunye nokucoca, kunye nokhuseleko olusebenzisana ngesandla. Ukusetyenziswa okuguquguqukayo kweendlela ezintathu zolawulo kunokuhlangabezana neemfuno zoshishino zebhanki ye-XXX ukunciphisa umngcipheko wokuphunyezwa kunye nokuphucula ukufumaneka xa ishishini elitsha liqalisiwe.
Ixabiso loMthengi
1. Sebenzisa kakuhle i-bandwidth yenethiwekhi ukuphucula iingenelo zeshishini
Ngesisombululo sokhuseleko siphela, ingozi yokhuseleko lwenethiwekhi ebangelwe kukuhlaselwa kwe-DDoS kwishishini le-intanethi leziko layo ledatha yayiyi-0, kwaye inkunkuma ye-bandwidth yenethiwekhi ebangelwe yithrafikhi engasebenziyo kunye nokusetyenziswa kwezixhobo zeseva kwancitshiswa, nto leyo eyadala iimeko zokuba ibhanki ye-XXX iphucule iingenelo zayo.
2. Nciphisa iingozi, qinisekisa uzinzo lwenethiwekhi kunye nozinzo lweshishini
Ukusasazwa kwezixhobo ze-anti-ddos ngendlela engafanelekanga akutshintshi uyilo lwenethiwekhi ekhoyo, akukho mngcipheko wokususwa kwenethiwekhi, akukho ndawo inye yokusilela, akukho mpembelelo ekusebenzeni okuqhelekileyo kweshishini, kwaye kunciphisa iindleko zokuqalisa kunye neendleko zokusebenza.
3. Ukuphucula ulwaneliseko lwabasebenzisi, ukuqinisa abasebenzisi abakhoyo kunye nokuphuhlisa abasebenzisi abatsha
Ukubonelela abasebenzisi ngemeko-bume yonxibelelwano yokwenyani, iibhanki ezikwi-intanethi, imibuzo yeshishini elikwi-intanethi kunye nolwaneliseko lwabasebenzisi beshishini elikwi-intanethi luye lwaphucuka kakhulu, luqinisa ukuthembeka kwabasebenzisi, ukuze kubonelelwe abathengi ngeenkonzo zokwenyani.
