Ukugcinwa kwemfihlo, ubuqotho nokutholakala

Ukugcina imfihlo, ubuqotho, nokutholakala, okuvame ukubizwa ngokuthi yi-CIA triad, kuyizakhi zokwakha ukuphepha kolwazi. Lokhu okuthunyelwe kuchaza igama ngalinye ngezibonelo.

Noma ikuphi ukuhlaselwa kwesistimu yolwazi kuzofaka engozini eyodwa, ezimbili, noma zontathu lezi zinto. Ngokuya ngokuthi iyiphi yalezi zingxenye ebeka engcupheni kakhulu, izilawuli zokuphepha ezisebenza kahle zingakhiwa ngendlela efanele.

Ukugcina kuyimfihlo

Ngamagama alula, imfihlo isho okuthile okuyimfihlo futhi okungafanele kudalulwe kubantu noma izinhlangano ezingahlosiwe.

Imfihlo iqinisekisa ukuthi imininingwane ebucayi itholakala kuphela kumuntu ogunyaziwe futhi igcinwe kude nalabo abangagunyaziwe ukuba nayo.

Wonke umuntu unemininingwane afisa ukuyigcina iyimfihlo. Ngakho-ke Ukuvikela imininingwane enjalo kuyingxenye ebalulekile yokuphepha kwemininingwane.

Izibonelo zolwazi oluyimfihlo

  • Izitatimende ze-akhawunti yasebhange
  • Ulwazi lomuntu siqu
  • Izinombolo zekhadi lesikweletu
  • Izimfihlo zokuhweba
  • Imibhalo kaHulumeni

Uma kwenzeka ukuthi okuyimfihlo kuthinteka, kungaholela ekufinyeleleni okungagunyaziwe kolwazi lomuntu siqu noma ukulahlekelwa yimfihlo ngokuphelele!

Izibonelo zokuhlaselwa okuthinta imfihlo

  • Ukuhogela iphakethe
  • Ukuqhekeka kwephasiwedi
  • Ukuntywila edumpster
  • Ukuthwebula ngocingo
  • Ukubhloga okhiye
  • Ubugebengu bokweba imininingwane ebucayi

Izindlela zokuqinisekisa imfihlo

  • Amagama wabasebenzisi namaphasiwedi
  • Ukuqinisekiswa kwezinto ezimbili
  • Ukuqinisekiswa kwe-biometric
  • Amathokheni okuphepha noma ama-fobs okhiye
  • Ukubethela kwedatha

Ubuqotho

Ngokomongo womhlaba wokuphepha kolwazi (InfoSec), ubuqotho busho ukuthi uma umthumeli ethumela idatha, umamukeli kufanele athole imininingwane efana ncamashi naleyo ethunyelwe umthumeli.

Idatha akumele ishintshwe ekuhambeni. Isibonelo, uma othile ethumela umlayezo 'Sawubona!', Umamukeli kufanele athole 'Sawubona!' Lokho wukuthi, kufanele kube idatha efanayo ncamashi naleyo ethunyelwe umthumeli. Noma ikuphi ukungezwa noma ukukhishwa kwedatha ngesikhathi sokuhamba kungasho ukuthi ubuqotho bonakalisiwe.

Isibonelo sokuhlaselwa okuthinta ubuqotho

  • Ukuhlaselwa kweSalami
  • Ukuhlaselwa kwedatha
  • Ukudunwa kweseshini
  • Ukuhlaselwa kweMan-in-middle (MITM)

Ukutholakala

Ukutholakala kusho ukuthi ulwazi luyatholakala kuzinhlangano ezigunyaziwe noma kunini lapho kudingeka khona. Ukungatholakali kwedatha nezinhlelo kungaba nemiphumela emibi.

Kubalulekile ukuba nezinhlelo nezinqubo ezikhona ukuvimbela noma ukunciphisa ukulahleka kwedatha ngenxa yenhlekelele. Uhlelo lokubuyiselwa kwezinhlekelele kumele lubandakanye izehlakalo ezingalindelekile ezifana nezinhlekelele zemvelo nomlilo.

Umsebenzi wokulondoloza ojwayelekile uyelulekwa ukuze uvimbele noma unciphise ukulahleka kwedatha okuphelele kusuka kuzimo ezinjalo.

Futhi, imishini yokuphepha eyengeziwe noma isoftware efana nezicishamlilo nezinsiza zommeleli zingavikela isikhathi sokuphumula nedatha engatholakali ngenxa yezenzo ezinonya njengokuhlaselwa kwe-denial-of-service (DoS) kanye ne-network intrusions.

Isibonelo sokuhlaselwa okuthinta ukutholakala

  • Ukuhlaselwa kwe-DoS ne-DDoS
  • Ukuhlaselwa kwezikhukhula ze-SYN
  • Ukuhlaselwa ngokomzimba kwingqalasizinda yeseva
