Kill switch yohlelo lokusebenza ne-kill switch ye-firewall: yini evinjelwa yilowo nalowo

I-kill switch ohlwini lwezici ayisho cishe lutho ngokwenzeka lapho umhubhe uwa. Enye indlela yokusebenza ivale izinqubo ezikhethiwe, enye ifaka izihlungi zamaphakethe emngceleni wesistimu yokusebenza, kanti eyesithathu izama nje ukuxhuma kabusha. Umehluko ubonakala emizuzwini yesibili ngemva kokwehluleka, hhayi esikrinini sezilungiselelo. Hamba kulezi zivivinyo ngokulandelana futhi ume kokokuqala ongakwazi ukuphendula ngokwethembeka, ngoba yilapho ukukhushulwa kwakho kwangempela kuphela khona.

Qala ngokusho indlela yokuphoqelela

Ukunqamula izinqubo kuyisici somjikelezo wempilo yohlelo. Ithola izinhlelo ezikhethiwe ngemva kokutholwa kokwehluleka komhubhe bese izivala. Konke okungeyona inqubo eyinhloko kuyasinda: izinsizakalo eziyisizo, ukuvumelanisa kwangemuva kanye nanoma yiluphi uhlelo olusungulwa ngemva kwesekhondi elilodwa, ngakunye kunomjikelezo wempilo naso isikhathi sakho.

Ukuhlunga amaphakethe kuyisici sesistimu yokusebenza. Kwenqaba ithrafikhi engalandeli indlela evunyelwe, okuyisithembiso esiqinile, kodwa kuphela ngokwezinga umthetho ohlangana nalo ngempela. Umndeni wekheli, isixhumi, izinhlelo ezikhishiwe kanye nezihluzo kunquma lokho, hhayi ilebula ekuklayenti.

Ingabe ukuvinjwa kuphila isikhathi eside kuneklayenti?

Buza imibuzo emine ngalokhu kulandelana: kwenzekani lapho kuphahlazeka, lapho uphuma ngesandla, lapho uphuma ngemvume kanye lapho uqalisa kabusha. Umthetho ogcinwa yiklayenti ngokwalo uvame ukususwa lapho kuvalwa kahle futhi ngokuvamile usala ngemva kokuphahlazeka. Umthetho ofakwe esitolo seplathifomu ungasabela ngokuphambene: usinde kukho kokubili iklayenti futhi ngezinye izikhathi nokususwa kwayo.

Vala iklayenti phakathi nokulanda isikhathi eside bese ubheka ukuthi ukudluliswa kuyama noma kuyaqhubeka.

Funa izimbobo ezijwayelekile

I-IPv6 ingenye yokuqala. Umthetho obhalelwe amakheli e-IPv4 ushiya ithrafikhi ye-IPv6 ingathintwanga, futhi amaklayenti amaningi abhala uhhafu we-v4 kuphela. Eyesibili isixhumi: i-USB tethering, i-adaptha yesibili ye-Wi-Fi kanye nemodemu yeselula kungenzeka zingafakiwe emthethweni olinganiselwe kuxhumano oluyinhloko. Izinhlelo ezikhishiwe kanye nezihluzo zenethiwekhi yasendaweni kungunyesithathu.

Ku-Windows ungafunda imithetho efakiwe esikhundleni sokuthemba iswishi: Get-NetFirewallRule -DisplayName '*VPN*' ne-netsh wfp show filters zombili zibonisa okukhona. Ku-Linux iptables -S, ip6tables -S ne-nft list ruleset zihlanganisa izimo ezijwayelekile, futhi ukuqhathanisa zontathu yiwo umongo.

I-DNS iwukuvuza okuvamile

Ukuvimba i-TCP ngesikhathi i-UDP 53 ivuliwe kukunikeza i-kill switch ekholisayo kakhulu esaphendula wonke umbuzo wegama lomsingathi. Kuyafana nalapho i-DNS inikezwa isixazululi kwenye isixhumi, noma lapho iklayenti ivimba i-v4 kuphela futhi isixazululi sifinyeleleka nge-v6.

Lapho umhubhe uphansi, xazulula igama elilodwa elaziwayo bese ubheka ukuthi impendulo iyabuya yini. Uma ibuya, ithrafikhi ayivinjelwanga ngokuphelele, noma yini isithonjana sesimo esiyishoyo.

Hlola uguquko, hhayi iswishi

Ukucisha i-VPN kusuka kumenyu yayo uqobo ukuvalwa okuhle, futhi icala elihle yilona uhlelo ngalunye olusingatha kahle. Uguquko olubalulekile olunzima: bulala inqubo yomhubhe, donsa inethiwekhi, vumela iseva iyeke ukuphendula. Bese uqala isicelo bese ubheka ukuthi siyahluleka noma sisebenzisa buthule isixhumanisi somzimba.

Umphumela ovela kukhompyutha ephathekayo awudluliselwa efonini noma kurotha. Ama-API eplathifomu ahlukene, okungasinakho okuzenzakalelayo okuhlukene, futhi ku-Android umehluko usobala: i-always-on enokuvimbela isetshenziswa uhlelo hhayi iklayenti, ngakho-ke iyaqhubeka nokusebenza lapho iklayenti ingasebenzi. Umhlahlandlela we-VPN we-Android uchaza lokho kwehlukaniswa.

Gcina indlela yokubuyela emuva

Ukuvimbela ezingeni lesistimu kunendlela ephambene yokwehluleka. Izihlungi eziphila isikhathi eside kuneklayenti zingashiya umshini ungenayo inethiwekhi ngokuphelele ngemva kokususwa, okuwucingo lokusekelwa olungenasizathu esicacile. Ngaphambi kokuvula noma iyiphi i-kill switch ebhala imithetho yeplathifomu, qopha ukuthi isuswa kanjani, futhi gcina indlela yokulungisa yomthengisi lapho ungayithola khona.

Uma ungakwazi ukuphendula izivivinyo zokuphahlazeka, i-IPv6, i-DNS nokuguquka kuklayenti yakho, kubheke njengeswishi yezinga lohlelo enezimbobo ezaziwayo futhi uhlele ngokufanele.
