Amathiphu wokwenza ukubethela okungenazintambo okungenasiphephelo okungenzeka ukuthi usebenzisa
Cabanga ukuthi inethiwekhi yakho engenantambo iphephile ngoba usebenzisa ukubethela kwe-WPA2 esikhundleni se-WEP? Cabanga futhi (kodwa cabanga "cha" ngalesi sikhathi). Lalela, bantu! Lokho engingakutshela khona kukhona inhlabathi-izibhulu zakho izinto eziyingozi ngakho sicela ulalele.
Nginesiqiniseko manje ukuthi cishe nonke nifunde okunye noma ama-athikili amaningi mayelana nabaduni abawela kumanethiwekhi angenantambo ngokuchofoza ukubethelwa kwe- Wired Equivalent Privacy (WEP) okusetshenziselwa ukuwavikela. Lezo zindaba zakudala. Uma usasebenzisa i-WEP , ungase unikele nje abaduni isihluthulelo sendlu yakho. Iningi labantu bayazi ukuthi i-WEP ingahle ibhidlizwe emigqeni yamasekhondi, okwenza kube yize ngokuphelele njengendlela yokuvikela.
Abaningi benu bathathe iseluleko se-geeks evikelekile njengami ngokwami futhi bayeke ukubethela kwe-Wi-Fi Protected Access 2 (WPA2) njengendlela yokuvikela inethiwekhi yakho engenantambo . I-WPA2 iyindlela yokubethela engenantambo engapheli futhi enamandla kakhulu etholakala ngalesi sikhathi.
Yebo, ngiyazonda ukuba yizindaba ezimbi, kodwa abaduni bebelokhu bekhandleka ekuqhekekeni igobolondo le-WPA2 futhi baphumelele (ngezinga).
Ukuze kucace, abaduni baye bakwazi ukuphahla i-WPA2-PSK (IsiKhathi Esibanjelwe Ngaphambi), esetshenziswa ngokuyinhloko ngabasebenzisi abaningi basekhaya nabancane. I-WPA2-Enterprise, esetshenzisiwe ezweni lezinkampani, inokusetha okunzima kakhulu okubandakanya ukusetshenziswa kwe-server ye-RADIUS yokuqinisekisa futhi kusengcono ukubheja okuphephile kokuvikela okungenantambo. I-WPA2-Enterprise ayikakalwanga ulwazi lwami.
"Kodwa u-Andy, ungitshele kwezinye izihloko ukuthi i-WPA2 yindlela engcono kakhulu yokuhamba nayo yokuvikela inethiwekhi yami ye-wireless. Ngingenzenjani manje?", Usho.
Ungesabi, akuyona embi njengoba kuzwakala, kusekhona izindlela zokuvikela inethiwekhi yakho esekelwe i-WPA2-PSK ukuvimbela abaduni abaningi ekuphukeni ukubethela kwakho bese ungena kwinethiwekhi yakho. Sizofika kulokho ngomzuzu.
Abahlaseli baye baphumelela ekuphambeni i-WPA2-PSK ngezizathu ezimbalwa:
Abasebenzisi abaningi benza ama-Keys angakabiwa ngaphambilini (amaphasiwedi wenethiwekhi angenantambo)
Uma usungula iphuzu lakho lokufinyelela elingenantambo futhi unike amandla i-WPA2-PSK njengemfihlo yakho, kumele udale Ukhiye Okwabiwe ngaphambilini. Ungase ukwazi ukusetha ukhiye ongeyena owawunikwe ngaphambilini ngoba wazi ukuthi kuzodingeka ufake leli phasiwedi kuzo zonke idivaysi ye-Wi-Fi ofuna ukuyixhuma kunethiwekhi yakho engenantambo. Ungase futhi ukhethe ukugcina iphasiwedi yakho elula ukuze uma umngane efika futhi efuna ukuxhuma uxhumano lwakho olungenantambo ungamtshela iphasiwedi elula ukuyifaka, njenge: "Shitzus4life". Nakuba ukubeka okulula ukukhumbula iphasiwedi kwenza ukuphila kube lula kakhulu, futhi kwenza kube lula iphasiwedi yabafana ababi ukuba baqhekeze futhi.
Abaqaphi bangakwazi ukuqeda ama-Keys aKwabelwane abuthakathaka ngokusebenzisa amathuluzi wokuqhaqhazela amandla futhi / noma i- Rainbow Tables ukuphawula okhiye obuthakathaka ngesikhathi esincane kakhulu. Okufanele bayenze kuphela ukufaka i-SSID (igama lenethiwekhi elingenantambo), ukuthatha ukuxhunyanisana phakathi komklayenti ongenazintambo ogunyaziwe kanye nomzila ongenawo ucingo noma iphuzu lokufinyelela, bese uthatha lolo lwazi kwimvume yabo eyimfihlo ukuze "baqale ukuchoboza" njengoba sisho eningizimu.
2. Iningi labantu lisetshenziselwa ukuxhumana okuzenzakalelayo noma okujwayelekile okungaxhunyiwe ku-wireless (SSIDs)
Uma usungula indawo yakho yokufinyelela engenantambo uguqule igama lenethiwekhi? Mhlawumbe isigamu sabantu emhlabeni sishiye i- SSID yokuzenzakalela ye-Linksys, i-DLink, noma noma yini umenzi ayeyibeke njengento ezenzakalelayo.
Abakhohlisi bathatha uhlu lwama-SSID aphezulu kakhulu angu-1000 futhi bakhiqiza ama-Rainbow Tables ama-password wokuqeda i-password ukuze enze ukuchofoza ama-Key Pre-Shared of amanethiwekhi usebenzisa i-SSID ejwayelekile kakhulu esheshayo futhi elula. Ngisho noma igama lakho lenethiwekhi lingekho ohlwini bangakwazi ukudala amatafula e-rainbow egameni lakho elithile lenethiwekhi, kuthatha isikhathi esiningi kakhulu nezinsiza zokwenza kanjalo.
Ngakho yini ongayenza ukuze wenze inethiwekhi yakho engenantambo ye-WPA2-PSK ivikeleke kakhulu ukuvimbela abantu ababi ukuthi bangene?
Yenza ukhiye wakho owabiwe ngaphambilini ngaphambi kwezinhlamvu ezingu-25 ubude futhi wenze kube okungahleliwe
Amandla we-Brute-Force ne-Rainbow Amathebula wokuphulwa kwephasiwedi anezilinganiso zawo. Uma sekuyisiKhiye Okwabiwe Ngaphambi, i-Rainbow Table yayizobe iyadingeka ukuyiqeda. Amandla we-computing kanye nomthamo we-hard drive adingekayo ukusekela ukukhwabanisa kwama-Keys Oku-Okwabiwe ngaphambilini akusebenzisanga okhiye okwedlule kunezinhlamvu ezingaba ngu-25. Kungakhathaliseki ukuthi kungabangela ubuhlungu ukuthi ufake iphasiwedi yezinhlamvu ezingu-30 kudivayisi ngayinye engenantambo, kuzodingeka uyenze kuphela kumadivaysi amaningi ngoba ngokuvamile ifihla lephasiwedi ngokungapheli.
I-WPA2-PSK isekela kufinyelela ku-63-Uhlamvu Lwabelwane Ngaphambi Kokuhlanganyela ukuze ube nendawo enkulu yezinto ezinzima. Thola ubuciko. Faka inkondlo ye-Haiku yaseJalimane lapho uma uthanda. Hamba amantongomane.
Qinisekisa ukuthi i-SSID yakho (igama lenethiwekhi elingenantambo) lifana nokungahleliwe ngangokunokwenzeka
Ngokuqinisekile ufuna ukuqiniseka ukuthi i-SSID yakho ayikho kuhlu lama-SSID aphezulu kakhulu angu-1000 njengoba kushiwo ngaphambili. Lokhu kuzokuvimbela ukuba ube yi- target elula yabaduni abavele benamathebula we-rainbow ngaphambilini abakhelwe ukuxhunyeka amanethiwekhi ngama- SSID ajwayelekile. Okungahleliwe ngegama lakho lenethiwekhi , kungcono. Phatha igama njengoba ungathanda iphasiwedi. Yenze kube nzima futhi ugweme ukusebenzisa noma yikuphi amagama aphelele. Ubude obuningi be-SSID buyizinhlamvu ezingu-32.
Ukuhlanganisa lezi zinguquko ezimbili ngenhla kuzokwenza inethiwekhi yakho engenazintambo ihlose kanzima kakhulu ukuyibeka. Ngethemba ukuthi abashayeli abaningi bazoqhubeka nokunye okulula njengokuthi inethiwekhi engenazintambo yomakhelwane wakho, "osibusisa inhliziyo yakhe" njengoba sisho eningizimu, mhlawumbe sisasebenzisa i-WEP.
