Ukuhlaselwa kweDDoS: njani ukwenza? Inkqubo ye-DDoS-attack

Mhlawumbi abaninzi abasebenzisa iikhomputha kunye ne-Intanethi baye bakuva malunga nobukho be-DDoS-attack, eyenziwa ngabaphangi ngokumalunga naluphi na isayithi okanye iinkonzo zeenkampani ezinkulu. Makhe sibone oko kuhlaselwa kwe-DDoS kukuthi, njani ukwenza wena kunye nendlela yokuzikhusela kwizenzo ezinjalo.

Yintoni ukuhlaselwa kweDDoS?

Ukuqala, mhlawumbi, kukufanele ukuphanda ukuba zeziphi izenzo ezingekho mthethweni. Siza kuxubusha kwangoko ukuba xa sicinga ngesihloko esithi "Ukuhlaselwa kweDDoS: indlela yokwenza ngokwakho", ulwazi luza kufakwa kuphela ukuhlaziywa, kungekhona ukusetyenziswa ngokufanelekileyo. Zonke izenzo zolu hlobo zihlawuliswa ngecala.

Ukuhlaselwa kakhulu, ngokubanzi, kukuthumela inani elaneleyo leencelo kwiservisi okanye kwisiza, okuthi, ngokugqithiseleyo umda wokufikelela, ukuvimba umsebenzi wewebhu okanye inkonzo yomnikezeli ngendlela yokukhubaza umncedisi ngesofthiwe yokhuseleko, izixhobo zokucima umlilo okanye izixhobo ezizodwa.

Kucacile ukuba ukuhlaselwa kwe-DDoS ngezandla zabo akunakuliswa ngumsebenzisi omnye kwi-terminal yekhompyutha ngaphandle kweenkqubo ezizodwa. Ekugqibeleni, ngokuqinisekileyo, akayi kuhlala apha ngeentsuku ekugqibeleni kwaye yonke iminithi ithumele izicelo kwisayithi ehlaselwa. Inombolo enjalo ayiyi kusebenza, njengokhuselo kwi-DDoS ukuhlaselwa kunikwe umboneleli ngamnye, kwaye omnye umsebenzisi akakwazi ukubonelela ngeenombolo zezicelo kwisiphakeli okanye kwisayithi ukuba ixesha elifutshane lidlule umda weefowuni kwaye kubangele ukukhutshwa kwezixhobo ezahlukeneyo zokukhusela. Ngoko ukudala ukuhlaselwa kwakho kufuneka usebenzise enye into. Kodwa ngaphezu koko emva koko.

Kutheni kukho ingozi?

Ukuba uqonda oko kuhlaselwa kweDDoS kukuthi, njani ukuyenza kwaye uthumele inani elidlulileyo lezicelo kumncedisi, kuyafaneleka ukuqwalasela iindlela ezenziwa ngayo ezinjalo.

Ezi ziyakwazi ukungazithembeki ngomlilo, ezingenakukwazi ukujamelana nenani elikhulu lezicelo, izimbobo zokukhusela kwinkqubo yokukhusela yomboneleli okanye kwiinkqubo zokusebenza ngokwabo, ukungabikho kwemithombo yenkqubo yokucwangcisa izicelo ezingenayo kunye nokucinywa kwenkqubo okanye ukucima ukukhawuleza, njl njl.

Ngethuba lokuqala kwelo hlobo, ukuhlaselwa kwe-DDoS kwenzelwe ngokubanzi ngabaprogram ngokwabo, abaye bazama kwaye bavavanya nayo ngokusebenza kweenkqubo zokukhusela. Ngokweqile, i-IT-giants ezifana ne-Yahoo, iMicrosoft, eBay, i-CNN kunye nabanye abaninzi baye bavalelwa kwizenzo zabangenayo abasebenzisa i-DoS ne-DDoS njengezixhobo. Umzuzwana obalulekileyo kulawo maxesha wayezama ukuphelisa abakhuphiswano ngokumalunga nokunciphisa ukufikelela kwiimithombo zabo ze-intanethi.

Ngokubanzi, kunye nabarhwebi bekhompyutha bakutshanje benza into efanayo. Ukwenza oku, ulandelele kuphela inkqubo yokuhlaselwa kwe-DDoS, ngokufanelekileyo, ngoko, njengoko bethetha, umcimbi wethekhnoloji.

Iintlobo zezihlaselo zeDDoS

Ngoku ngamagama ambalwa malunga nokuhlelwa kohlaselo lwale hlobo. Into ebalulekileyo kuyo wonke umntu kukukhubaza umncedisi okanye indawo. Uhlobo lo kuqala lunokubakho iiphoso ezihambelana nokuthunyelwa kwemiyalelo engalunganga kumncedisi ukuze kusebenze, ngenxa yoko ukupheliswa kokungaqhelekanga kokusebenza kwayo kwenzeka. Inketho yesibini kukuthumela ngokugqithiseleyo kwedatha yomsebenzisi, okukhokelela ekuvavanyeni okungapheliyo (umjikelezo we-cyclic) ngokunyuka komthwalo kwiinkqubo zenkqubo.

Uhlobo lwesithathu lukhukhula. Njengomthetho, ngumsebenzi wezithuba zangaphambili ezenziwe ngaphambili (ezingenanto) kwiinkonzo zeseva okanye inethiwekhi ukwenzela ukwandisa umthwalo. Uhlobo lwesine lubizwa ngokuba yi-congestion yeziteshi zonxibelelwano ngamakheli amanga. Olunye uhlaselo lunokusetyenziswa, olukhokelela ekubeni inkqubo yekhompyutyana ishintsha ukucwangciswa, okukhokelela ekusebenzeni kwayo ngokupheleleyo. Ngokubanzi, ungabhala ixesha elide.

Ukuhlaselwa kweDDoS kwisayithi

Ngokuqhelekileyo, lo hlaselo luhambelana nokusingathwa okuthe ngqo kwaye lujoliswe kuphela kwisibonelelo esisodwa esicacisiwe sewebhu (kumzekelo kwisithombe esingezantsi esichazwe ngokuqhelekileyo njengomzekelo.com).

Ukuba inani lokufikelela kwisayithi liphezulu kakhulu, ukungaphumeleli kokunxibelelana kwenzeka ngenxa yokuthintela ukunxibelelana kungekhona kwisiza ngokwaso kodwa ngecandelo lomncedisi wenkonzo, okanye kunoko, kungekhona kwiseva okanye kwinkqubo yokhuseleko ngokwayo, kodwa ngeenkonzo zenkxaso. Ngamanye amazwi, olo hlaselo lujolise ekuqinisekiseni ukuba umnini wokusingatha ufumana ukukhishwa kwenkonzo kumniki-mboleko xa umda othile wezontengiso unqabile.

Ukuhlaselwa kweDDoS kumncedisi

Ngokubhekiselele ekuhlaseleni i-server, apha azijolise kuyo nayiphi na indawo yokubamba, oko kukuthi umboneleli onika lona. Kwaye akunandaba nokuba ngenxa yoko, abanini beendawo bangabandezeleka. Ixhoba eliphambili ngumboneleli.

Isicelo sokulungiselela ukuhlaselwa kweDDoS

Ngoko safika ekuqondeni oko kuhlaselwa kweDDoS. Indlela yokwenza ngayo ngoncedo lweenkonzo ezizodwa, ngoku kwaye siyaziqonda. Siyabona ngokukhawuleza ukuba izicelo zale fayile azikwahlulwa njengemfihlo. Kwi-intanethi bafumaneka ukukhuphela mahala. Ngoko, umzekelo, inkqubo elula kakhulu neyaziwayo yokuhlaselwa kweDDoS ebizwa ngokuthi i-LOIC ibeka ngokukhululekile kwiWebhusayithi yeWebhu yokukhuphela. Ngoncedo lwawo, unokuhlasela kuphela iisayithi kunye nezikhumbuzo ngee-URL ezaziwa ngaphambili nee-IP.

Ungayifumana njani i-IP-dilesi yexhoba, ngenxa yezizathu zokuziphatha esiza kuziqwalasela ngoku. Siyaqhubeka kwi nyaniso yokuba sinayo idatha yokuqala.

Ukuqala isicelo, ifayile esebenzayo iLoic.exe isetyenzisiweyo, ngoko ke iilesi zokuqala zibhalwa emacaleni amabini aphezulu kwicala lasekhohlo, kwaye emva koko iifayile ezimbini "Vala kwi" zicatshulwa - kancinci ngakwesokudla kumqolo ngamnye. Emva koko, idilesi yexhoba lethu livela efestile.

Ngezantsi zikhona izidibanisi zokulungiswa kwesantya sokudluliselwa kwesicelo se-TCP / UDF kunye ne-HTTP. Ixabiso elingagqibekanga lisetyenziswe ku- "10". Sinyusa ukuya kumda, emva koko sicinezela iqhosha elikhulu "IMMA CHARGIN MAH LAZER" ukuqala ukuhlaselwa. Ungayimisa ngokucinezela iqhosha elifanayo kwakhona.

Ngokwemvelo, enye inkqubo enjalo, edlalwa ngokuba yi "laser cannon," ayiyi kubangela ingxaki kumthombo othile okanye umboneleli, kuba ukukhuselwa kwi-DDoS kuhlaselwa khona. Kodwa ukuba iqela labantu basebenzisa ezili-12 okanye ngaphezulu kweeononi ngexesha elifanayo, into enokufezekiswa.

Ukukhuselwa kuhlaselo lweDDoS

Ngakolunye uhlangothi, nabani na ozama ukuzama ukuhlaselwa kweDDoS kufuneka baqonde ukuba "kwicala", kwakhona, akukho zihlunu zihleli. Bakwazi ukubala ngokulula iadesi apho ukuhlaselwa okunjalo kwenziwa khona, kwaye le nto ibangelwa yimiphumo embi kakhulu.

Ngokumalunga nabanini abaqhelekileyo abamkela, ngokuqhelekileyo umniki-nkonzo unika ngokukhawuleza iphakheji yeenkonzo kunye nokukhusela okufanelekileyo. Kukho iindlela ezininzi zokukhusela ezinjalo izenzo. Oku kukuthi, ukubuyisela ukuhlaselwa kumhlaseli, ukuphindaphinda izicelo ezingenayo kumaseva athile, ukucoca i-traffic, ukuphinda iinkqubo zokukhusela ukukhusela ukukhupha kwabo, ukuzakhela izixhobo, njl. Kakhulu, akukho nto inokukhathazeka ngayo njengomsebenzisi oqhelekileyo.

Esikhundleni sokulandelelana

Ndicinga ukuba kule nqaku kuyacaca ukuba ukwenza iDDoS-zihlasele ngokwaso kunye nokufumaneka kwesoftware ekhethekileyo kwaye enye idatha yokuqala yezabasebenzi ayiyi kuba. Enye into - ngaba kulungele ukujongana nayo, kunye nomsebenzisi ongenamava othe wagqiba ukwenza, ngoko, ngenxa yemidlalo? Wonke umntu kufuneka aqonde ukuba izenzo zakhe naluphi na uhlobo luya kubangela ukusetyenziswa kwamanyathelo okubuyiselwa kwinqanaba lokuhlaselwa, kwaye, njengommiselo, ungayithandi umsebenzisi owasungula ukuhlaselwa. Kwaye emva koko, ngokweMigaqo yePalato yamazwe amaninzi, unokufumana izigqibo ezinjalo, njengoko zithethayo, kwiindawo ezingaqhelekanga kangangeminyaka emibini. Ngubani ofuna oku?
