Iyini i-WPA3 Security?
I-WPA3, eyaziwa nangokuthi i-Wi-Fi Protected Access 3, imele isizukulwane sakamuva sokuphepha okujwayelekile kumanethiwekhi angenantambo. Uma kuqhathaniswa nezinga elidumile le-WPA2 (elikhishwe ngo-2004), linyusa izinga lokuphepha ngenkathi ligcina ukuhambisana okubuyela emuva.
Izinga le-WPA3 lizobethela yonke idatha kumanethiwekhi omphakathi e-Wi-Fi futhi lingaqhubeka nokuvikela amanethiwekhi angavikelekile e-Wi-Fi. Ikakhulukazi uma abasebenzisi basebenzisa amanethiwekhi omphakathi njengezindawo zehhotela nezindawo zezivakashi ze-Wi-Fi, ukudala ukuxhumana okuvikeleke kakhulu nge-WPA3 kwenza kube nzima kubageli be-inthanethi ukuthola ulwazi oluyimfihlo. Ukusebenzisa umthetho olandelwayo we-WPA3 kwenza inethiwekhi yakho ye-Wi-Fi imelane kakhulu nezingozi zokuphepha njengokuhlaselwa kwesichazamazwi ungaxhunyiwe ku-inthanethi.
Izici Eziyinhloko Zokuphepha ze-WPA3
1. Ukuvikela Okuqinile Ngisho Namaphasiwedi Abuthakathaka
Ku-WPA2, ubungozi obubizwa nge-“Krack” butholakele obusiza lokhu futhi buvumela ukufinyelela kunethiwekhi ngaphandle komushwana wokungena noma iphasiwedi ye-Wi-Fi. Kodwa-ke, i-WPA3 inikeza uhlelo lokuvikela oluqinile ekuhlaselweni okunjalo. Uhlelo luvikela ngokuzenzakalelayo uxhumo ekuhlaselweni okunjalo ngisho noma igama eliyimfihlo elikhethwe umsebenzisi noma umushwana wokungena ungahlangabezani nezidingo ezincane.
2. Ukuxhumana Okulula Kumadivayisi Angenakho Isibonisi
Umsebenzisi uzokwazi ukusebenzisa ifoni noma ithebulethi yakhe ukuze alungiselele enye idivayisi encane ye-IoT efana nesikhiya esihlakaniphile noma insimbi yokuncencethwa emnyango ukuze asethe iphasiwedi esikhundleni sokuyivulela noma ubani ukuba ayifinyelele futhi ayilawule.
3. Ukuvikelwa Okungcono Komuntu Ngamunye Kumanethiwekhi Omphakathi
Uma abantu besebenzisa amanethiwekhi omphakathi angadingi amaphasiwedi ukuze baxhumeke (njengalawo atholakala ezindaweni zokudlela noma ezikhumulweni zezindiza), abanye bangasebenzisa la manethiwekhi angabethelwe ukuze bantshontshe idatha yabo ebalulekile.
Namuhla, ngisho noma umsebenzisi exhunywe kunethiwekhi evulekile noma yomphakathi, uhlelo lwe-WPA3 luzobethela uxhumano futhi akekho ongafinyelela idatha edluliswa phakathi kwamadivayisi.
4. I-192-bit Security Suite Yohulumeni
I-algorithm yokubethela ye-WPA3 ithuthukiselwe ku-algorithm yezinga le-192-bit CNSA, i-WiFi Alliance eyichaza ngokuthi "i-192-bit security suite". I-suite iyahambisana ne-National Security Systems Council National Commercial Security Algorithm (CNSA) suite, futhi izophinde ivikele amanethiwekhi e-Wi-Fi anezidingo zokuphepha eziphakeme, okuhlanganisa uhulumeni, ezokuvikela, kanye nezimboni.
