UkuCikiza

Mayelana Wikipedia
Computer simulation
Umfefenyeko wesiCikizi, enye yezindlelasu eziyinhloko zokucikza malunga.

Ukucikiza kuyinoma ibuphi ubuqhebeqhebe obugxike empokopheleni obudinga izinsiza, buzuze kuzo, noma budale izinguxa zokucikiza. Ukucikiza kuhlanganisa ucwaningo nomgcanso ngezinqubo zomkholezima, nokuthuthukiswa kokubili kwezinsiza ezingaphandle neziphakathi. Ukucikiza kunezici zenzululwazi, zomngcikisho, zomchazazibalo, zobuchwepheshe nezomphakathi. Izigaba zokucikiza ezinkulu zihlanganisa umngcikisho wesicikizi, Inzululwazi yesiCikizi, (cybersecurity), inzululwazi yemininingo, izimiso zokwaziswa, ezobuchwepheshe bokwaziswa kanye nomngcikisho wehlelokusebenza.[1]

Ibizo elithi "ukucikiza" limqondofana nelithi ukubala nelithi ukuqaqulula. Ezikhathini zangaphambili, lalisetshenziswa uma kukhulunywa ngomsebenzi owenziwa abacikizi abangabantu, manje owenziwa izinguxa zokucikiza.[2]

Umlando wokuCikiza mude ukwedlula umlando wezigcoyi zokucikiza futhi uhlanganisa nomlando wezindlelasu ezihloselwe ukwenziwa ngepeni nephepha (noma umcako nokhethe) ngosizo lwamacansi noma ngaphandle kwawo. UkuCikiza kuhlobene eduze nokumelelwa kwamanani, nakuba izicabango zomchazazibalo eziyimfuneko yokucikiza kungezangaphambi kwezinhlelo zezibalonani. Insiza yasendulo eyaziwayo eyayisetshenziswa ekucikizeni, isihlohlo sokubala, okucatshangwa ukuthi saqanjwa eBhabhiloni cishe maphakathi neminyaka yezi-2700 kuya kwezi-2300 BC.

IsiCikizi

[hlela | Hlela umthombo]

IsiCikizi siyinguxa ekwazi ukuthonya imininingo ngokuvumelana neqoqo leziyalezo ezibizwa izinhleleliso zesicikizi[3] Lenhleleliso inisimo esigunundekayo esingasetshenziswa isiCikizi ngokuqondile ukuze sigununde iziyalezo. Inhleleliso efanayo emkitizweni wayo ofundwa-umuntu, ivumela umhlelelisi ukuba afunde futhi athuthukise uthungethunge lwezinyathelo ezaziwa ngokuthi umkholezima.[4] Ngenxa yokuthi iziyalezo zingagunundwa izicikizi ezinhlobonhlobo, iqoqo elilodwa leziyalezo liguqulwa libe iziyalezo zenguxa ngokuvumelana nohlobo lwesidludlungi esimqoka.[5][6]

Uqeqesho lokucikiza

UmNgcikisho wesiCikizi

[hlela | Hlela umthombo]

UmNgcikisho wesicikizi wuqeqesho oludidiyela imikhakha embalwa njengomngcikisho wamazuba nenzululwazi yesiCikizi ezidingekayo ukuze kuthuthukiswe izigcoboyi nehlelokusebenza.[7]
