Iikhompyutha Modern, ukuphepha nemfihlo

Ngenxa computerization, ulwazi ngakumbi nangakumbi ikhutshelwa-elektroniki. Uninzi lwezi data ziyimfihlo. Ngokomzekelo, iingxelo beebhanki, yezonyango iimbali, njl Ngenxa yezizathu ezininzi, umsebenzisi akafuni ulwazi lwabo emehlweni prying. Ukuphucula ukufikelela kubuchwepheshe kunye nokusetyenziswa kwazo othatha ithuba elongezelelweyo mthethweni lwe kusebenziso olungavumelekanga. Ngokomzekelo, ungafowunela ufikelelo isixa esikhulu lwe data, WANs computer. Umbutho, abasebenzisi kunye neekhompyutha zabo ngelixa uqhagamshele kwiinethiwekhi ezinjalo, ziphantsi kwesoyikiso enkulu, ilahleko, ukulungisa iinkcukacha.
Usongo ukuba ezi networks kunzima ukufumana isela, xa uzingela ubunyani uqhekezo. Ingxaki yokhuseleko yenye imisebenzi ebalulekileyo ekufuneka isonjululwe liSebe indlela yokusebenza kunye software (system kunye software yokusebenza).

Inkqubo yekhompyutha, imiqathango yezokhuseleko, kumele ukuba ziqwalasele iinjongo ezintathu eziphambili. A kancinane ngakumbi ngezantsi.

1. Ukuba yimfihlo. umnini data bagqiba ukuba baya kunikwa khetha iqela labantu, ngoko inkqubo kufuneka ukuqinisekisa ukuba ukufikelela kule data akayi kuba nako ukufumana abantu abangekho kwesi sangqa.

2. Ingqibelelo data. Oku kubonisa ukuba abasebenzisi okungagunyaziswanga awuna mvume iimvumelwano ukuba uguqule idatha. Kwaye kuphela ngemvume yomnini, ngamanye amazwi, cima okanye uhlaziye naluphi na ulwazi.

3. Ubukho System. Ivelisa esonzakalisa inkqubo akekho. Namhlanje le ndlela Kucinywe lixhaphakileyo nodes Internet zibonakaliswe ukuhlasela nokwala kwenkonzo. Ukuthumela inani elikhulu lezicelo, esiludumbo ayikho nako ukwenza inkqubo, yaye ngenxa yoko aziyi kufumaneka. Le DDoS - uhlaselo. Ukwenza olu hlobo lokuhlasela kufuneka inani elikhulu iikhompyutha kunye software ezenziwe ngqo oku.

Inkqubo yokhuseleko mababe ukunika ubunzima gqithi kule imizamo yokufikelela engagunyaziswanga kunokwenzeka. Ngaphezu kwako konke, iinkqubo ezinjalo kufuneka banikwe ithuba ukuluqonda ukufikelela ulawulo, ukulungiselela ukukwazi umkhondo ukuzama ngokungekho ukufikelela. Ukuza kuthi ga ngoku, ukufikelela kulwazi zingafumaneka ngaphandle ngokwaphula inkqubo ngokwalo, kodwa ngenxa ubusela, ukubiwa ikhompyutha ukufumana ulwazi oluyimfuneko ngokuthi abhenele ukunyoba labasebenzi abakwaziyo ukufikelela kule data.

Ngenxa yoko, iikhompyutha nenkqubo yokhuseleko ngokugqibeleleyo busebenzisekayo ngokwasemzimbeni. zokwakha Practical iinkqubo zokhuseleko ngokusekelwe kwezoqoqosho.
