Ubani angakwazi ukuqagela iphasiwedi yakho ye-VPN ngokushesha okungakanani?
Uhambo lokuhamba nokubuya lulinganisa ukuxhumana, hhayi ukuthi amaphasiwedi angahlolwa ngokushesha okungakanani. Buza ukuthi imuphi umhloli ohlola ukuqagela nokuthi yimiphi imikhawulo ekhona eduze kwayo.
Ukubambezeleka kuphendula umbuzo ongazange ubuzwe muntu. Izimo ezintathu zinquma ukuthi isilinganiso sokuqagela sisho ukuthini ngempela: ukuthi ukuqagela kuhlolwa yisevisi ekhona noma ngokuqhathaniswa nezinto ezithunjiwe, iyiphi indlela yokuqinisekisa eyakha lezo zinto, nokuthi imiphi imikhawulo esetshenziswayo. I-ping ilinganisa uhambo olulodwa lokuhamba nokubuya endleleni eyodwa futhi ayiphenduli neyodwa yazo. Ukuhlukanisa isekhondi ngalelo nani kuveza inombolo enembile, engahlobene futhi evame ukuphindwa njengokungathi iyipropathi yokuphepha.
Ukubambezeleka kungokomsebenzi wokuxhumana. Amandla okuqinisekisa ayipropathi yomhloli kanye neprotocol.
Uhambo olulodwa akusiwo umkhawulo wezinga
Isikhathi sohambo lokuhamba nokubuya sichaza ukuthi isicelo esisodwa nempendulo yaso kuthatha isikhathi esingakanani endleleni ethile. Ngisho nasezilingweni ze-inthanethi, ukudluliswa kwedatha kuncike ekutheni iklayenti ligcina izicelo ezingaki zivuliwe, ukuthi iseva ichitha isikhathi esingakanani kusilingo ngasinye, nokuthi imikhawulo yezinga isetshenziswa kanjani. Lokhu akuncikile ku-ping. Isixhumanisi se-Ethernet asibeki umthetho wokuthi kungaba nesilingo esisodwa kuphela ohambweni ngalunye, futhi i-ping esheshayo ayifakazeli ukuthi umhloli uzokwamukela ukuqagela ngalelo zinga.
Uma isevisi ikhiya i-akhawunti ngemva kokwehluleka kahlanu, izinga elisebenzayo liyizilingo ezinhlanu ngewindi ngalinye lokukhiya, kungakhathaliseki inethiwekhi. Lowo umkhawulo, futhi yilowo nani ofanele ukucashunwa.
Ukuqagela kuhlolwa kuphi ngempela
Ku-inthanethi, umfakisicelo uthumela ikhandidethi ngalinye kwisevisi yangempela, engabuka, ibambezele, ikhiye futhi ixwayise. Ngaphandle kwe-inthanethi, umhlaseli onazo izinto zokuqinisekisa ezifanele uhlola amakhandidethi endaweni ngaphandle kokubamba iqhaza kwesevisi. Lowo mehluko unquma cishe konke kuzibalo. Imihlahlandlela ye-NIST yephasiwedi ibhekana nalezi zinsongo ngokuhlukene, ifuna ukuncishiswa kwezinga lezilingo ze-inthanethi ezingaphumelelanga kanye nokugcinwa okumelana nokuhlaselwa ngaphandle kwe-inthanethi ngokusebenzisa i-hashing enosawoti kanye nesici sezindleko. Kokubili kuyipropathi yomhloli kanye nongqimba wokugcina, ngaphandle kokuncika ekutheni isixhumanisi somsebenzisi siphendula ngokushesha okungakanani.
Ukuthi ukuthunjwa kwamaphakethe kuveza izinto eziwusizo kuncike kuprotocol nendlela yokuqinisekisa. Ukuba nokuthunjwa, isitifiketi noma umhubhe obethelwe akuphenduli lutho ngokwako, futhi iminyaka yokwakhiwa kweklayenti nayo ayiphenduli.
Kungani izibalo zesikhathi sokuqhekeza zidukisa
Inani lezinhlamvu ezingaba khona lihle kuphela njengezicatshangelwa zalo. Amaphasiwedi akhethwa abantu awasakazwa ngokulinganayo endaweni echazwa ifomula, futhi imininingwane yokungena esetshenziswe kabusha ingase ibe sesohlwini. Izindleko zokuhlola nazo zibalulekile: isevisi ye-inthanethi enemikhawulo esetshenzisiwe yehluke ngokuphelele kumhloli webiwe ohlolwa endaweni. Isibalo esihamba ngokuthula phakathi kwalezo zimo asikwazi ukusekela isimangalo seminyaka ngaphambi kokuqhekezwa.
Gcina ukushiyeka kwe-protocol kukholamu yako. Iphasiwedi ende ayilungisi ukwakheka kokuqinisekisa okubuthakathaka, futhi indlela eyodwa ephelelwe yisikhathi ayifakazeli ukuthi zonke izakhiwo ezisekelwe kuphasiwedi zabelana ngobuthakathaka bayo. Lokho kuyizitholakele ezihlukene ngemilungiso ehlukene.
Cela ubufakazi bomhloli, hhayi ukubambezeleka
Ukuze uhlole isango, khomba indlela yokuqinisekisa, ukuthi umhloli uphethwe ngubani, ukuthi yimiphi imikhawulo yezilingo ekhona nokuthi isici sesibili sizimele ngempela yini. Incwadi yengxoxo enamabhokisi amabili ephasiwedi ayisunguli izici ezimbili. Emininingwaneni egciniwe, thola ukuthi yiziphi izinto ezikhona, ukuthi ngubani ongazifunda nokuthi ukuqaliswa kusebenzisa luphi ukuvikelwa ngempela. Inombolo yokucabanga yejubane le-hashing ayibona ubufakazi mayelana nohlelo lokugcina olungaziwa.
Cabanga futhi ngokuchayeka ngaphandle kokuqagela. Iphrofayili ebiwe, indawo yokugcina ehlungisiwe noma ukugeleza kwe-phishing kuletha inkinga ehlukile kuneyomhlaseli obala amaphasiwedi, futhi ubude bephasiwedi abwenzi lutho mayelana negunya eselinikezwe isikhathi esisebenzayo.
Rekhoda indlela, umkhawulo nokuvikelwa kokugcina. Lokho kuthathu kuphendula umbuzo i-ping engakaze iwulinganise.
