Ngenhlanhla namuhla, izinkampani zefoni zinokunikezwa okuhle kwesilinganiso sedatha kubasebenzisi bazo. Asisahambi njengabasangana sifuna ibha nge khulula i-wifi, ngaphandle kokuthi kufanele usebenzise i-laptop noma i-iPad yakho ukusebenza isikhashana ngenkathi unekhofi.
Kepha uma kunjalo, futhi uyadonsa i-wifi yomphakathi, kufanele wazi ukuthi uzibeka obala ngokugqekezelwa. Ingozi incane, kepha ikhona, futhi udinga ukuyazi ukuthatha izinyathelo zokugwema izinkinga.
Ngenxa yokuncintisana okuqinile phakathi kwezinkampani zomakhalekhukhwini, namuhla akubizi kakhulu ukuba nakho idatha engenamkhawulo noma kwanele ukusetshenziswa kwethu kwansuku zonke. Asisavamile ukusebenzisa amanethiwekhi womphakathi we-Wi-Fi nama-iPhones ethu, kunalokho siwashiya lapho kufanele sisebenze nezethu iPads o MacBooks.
Ngakho-ke kufanele sazi ukuthi ukusebenzisa inethiwekhi yomphakathi ye-Wi-Fi inayo izingozi mayelana nokuphepha elisinikeza kona. Noma kungeyona into ejwayelekile, kufanele sikhumbule ukuthi inethiwekhi ye-Wi-Fi isengozini yokuhlaselwa, futhi imininingwane yethu ingavezwa.
Umcwaningi wezokuphepha onerekhodi eliqinile ekutholeni ukuba sengozini kwe-Wi-Fi uthole amaphutha amasha ezokuphepha ohlelweni lokuxhumana olungenantambo. Ezinye zazo ziyingxenye yezivumelwano ezinkulu zokuphepha ze- i-wifi ejwayelekile, yingakho bekhona cishe kuwo wonke amadivayisi kusukela ngo-1997.
I- "izimbobo zokuphepha»Kungasetshenziswa ukuntshontsha imininingwane eyimfihlo, ukulawula amadivayisi asekhaya ahlakaniphile futhi kuthathe amanye amakhompyutha. Noma kunjalo, kunezindaba ezimbili ezinhle. Okokuqala, izingozi zangempela zabasebenzisi abajwayelekile zincane kakhulu. Okwesibili, kulula ukuzivikela nakulezi zinsongo eziphansi.
Ngisho nephrothokholi ye-WPA3 isengozini
Lezi "zenzo" ezintsha zitholwe yiBelgian UMathy vanhoef, uchwepheshe wezokuphepha kwenethiwekhi. ichaza kuwebhusayithi yayo ukuthi la maphutha amasha okuphepha athinta amanethiwekhi we-Wi-Fi ngawo Iphrothokholi ye-WPA3, leyo okufanele iphephe kakhulu.

Ungakwazi ukukhulisa ukuvikelwa kwakho ngokusebenzisa amawebhusayithi I-HTTPS noma nini lapho kungenzeka noma sebenzisa i i-VPN lapho uxhuma ezindaweni zomphakathi.
