Ukulahlwa kweeNtsholongwane zeNkonzo kunye nokuba Kutheni kwenzeka
I- Denial of Service (DoS) ibhekisela kwiziganeko ezinika iinkqubo kwiinkonzo zekhompyutheni ezingenakulungiswa. Ukukhishwa kweenkonzo kunokwenzeka ngenzeka ngengozi ngenxa yezenzo ezithathwe ngabasebenzisi benethiwekhi okanye ngabalawuli, kodwa ngokuqhelekileyo zihlaselwa yi-DoS ezinobungozi .
Omnye uhlaselo oludumile lweDDoS (ngaphezulu kwezi zilandelayo) zenzeke ngoLwesihlanu, ngo-Oktobha 21, ngo-2016, kwaye zanikezela ezininzi iiwebhusayithi ezidumileyo ngokupheleleyo ezingenakunceda kangangoko.
Ukulahlwa kweeNkonzo zokuhlaselwa
Ukuhlaselwa kwe-DoS kusebenzisa ubuthakathaka obuhlukeneyo kwezobuchwepheshe beekhompyutha. Zingajolisa kumaseva , i- routers routers , okanye ikhonkco zonxibelelwano zenethiwekhi. Zingenza ukuba iikhomputha kunye nee-routers zivaliwe ("crash") kunye nezixhumanisi zokuhlahlela. Ngokuqhelekileyo ayibangeli umonakalo ongunaphakade.
Mhlawumbi indlela eyaziwayo kakhulu yeDoS yiPing of Death. Ukuhlaselwa kwePing Death kusebenza ngokuvelisa nokuthumela imiyalezo ekhethekileyo yomnatha (ngokukodwa, iipakethi ze- ICMP zamanani angaqhelekanga) ezibangela iingxaki kwiinkqubo ezizifumanayo. Kwiintsuku zokuqala zeWebhu, ukuhlaselwa kungabangela ukuba iinkonzo ze-Intanethi ezingakhuselekanga zikhawuleze.
Iziza zeWebhsayithi zanamhlanje ziye zagcinwa zikhuselekile kwi-DoS zihlasela kodwa ngokuqinisekileyo azikhuseli.
I-Ping yoFawulo yinto enye yokuphuphuma hlaselwa. Ezi zihlaselo zigqithise imemori yekhomputha yecandelo kwaye iphule i-logical logic yayo ngokuthumela izinto ezinobungakanani obukhulu kunokuba zenzelwe ukuphatha. Ezinye iintlobo ezisisiseko zokuhlaselwa kwe-DoS zibandakanya
- ukukhukula intanethi ngemisebenzi engenakusiza ukwenzela ukuba i-traffic yangempela ayikwazi ukufikelela. I- TCP / IP SYN kunye nokuhlaselwa kwe- smurf yimizekelo emibini eqhelekileyo.
- ukukhupha i-CPU inkqubo ngokukhululekileyo ukuze izicelo ezivumelekileyo zingenakucutshungulwa.
- Ukuguqula iimvume okanye ukuphulwa kwemigqaliselo yokugunyazisa ukukhusela abasebenzisi ukungena ngemvume kwi-system. Omnye umzekelo oqhelekileyo uquka ukuququzelela uchungechunge olukhawulezayo lwemizamo yokungena kwamangqina ekhusela iakhawunti ukuba ikwazi ukungena ngemvume.
- ukususa okanye ukuphazamisa izicelo okanye iinkonzo eziphambili zokukhusela ukusebenza kwazo eziqhelekileyo (nangona inkqubo kunye nenethiwekhi jikelele isebenza).
Ukuhlaselwa kwe-DoS kuxhaphake kakhulu kwiiWebhsayithi ezinika ulwazi okanye iinkonzo eziphikisanayo. Iindleko zemali zezi zihlaselo zingaba zikhulu kakhulu. Abo babandakanyekayo ekucwangciseni okanye ekusebenziseni ukuhlaselwa baxhomekeke ekutshutshiseni ubugebengu njengokuba kunjalo noJake Davis (umfanekiso) weqela lokuqhawula uLulzsec.
I-DDoS - Ukusasazwa kweNkonzo yeNkonzo
Ukukhanyela kwezemveli ukuhlaselwa kwenkonzo kubangelwa ngumntu omnye okanye ikhompyutha. Xa kuthelekiswa, ukuchaswa kwenkonzo yokuchasa (DDoS) iquka amaqela amaninzi.
Uhlaselo olubi lwe-DDoS kwi-intanethi, umzekelo, uququzelele amaninzi amakhompyutha kwiqela elidibeneyo elibizwa ngokuba yi- botnet ekwazi ukukhukula isayithi ejoliswe kuyo kunye neeninzi ezinkulu zendlela yokuthutha.
DoS engxamisekileyo
Ukukhishwa kweenkonzo kunokubangela ukuba kungabonakali ngeendlela ezininzi:
- abaninzi abasebenzisi ngokuzenzekelayo bazama ukufikelela kwinethiwekhi okanye iseva ngexesha elifanayo, njengokutyelela kwiWebhsayithi yomntu apho kwenzeka khona isiganeko esikhulu senhlalakahle
- abalawuli benethwekhi bavula ngokukhawuleza ikhebula, okanye baqwalasele ngokungalunganga ii-routers
- inkqubo yokusuleleka kwintsholongwane yekhompyutha okanye imbumbulu
