I-IPS ivimbe idathabheyisi nge-VPN: chaza ububanzi bokuhlukile
I-VPN ayikhululi ithrafikhi yangaphakathi yedathabheyisi ekuhlolweni. Qhathanisa ukucindezelwa kwesiginesha, ukukhishwa komthombo kanye nokukhutshazwa kwesigaba ngaphambi kokukhetha.
Ukuxhumana kwedathabheyisi ngaphakathi kwe-VPN kusavinjwa yi-IPS, ilogi yezehlakalo isho imbangela, futhi ukulungisa okusheshayo kubonakala njengokuhlukile. Ngaphambi kwalokho, qaphela ukuthi umhubhe ushintsha ini ngempela. Uvikela ithrafikhi phakathi kweziphetho zawo bese unikeza amaphakethe angaphakathi ajwayelekile kulokho okuhlola ingaphakathi lenethiwekhi, okuyindawo ngqo lapho isiginesha saqala khona. Umhubhe awukona ukukhululwa, futhi ukutholwa akulona iphutha ngokuzenzakalela.
I-decapsulation iyindawo lapho ukuhlola kuqala khona futhi
Ithrafikhi ephuma emhubheni ifika njengamaphakethe e-IP ajwayelekile abhekiswe kumsingathi wedathabheyisi. Noma iyiphi idivayisi yokuvimbela ukungena kuleyo ndlela iwahlola ngokwenqubomgomo yayo, yingakho uxhumano olwedlula isixhumanisi esibethelwe lungase lulahliwe umthetho obhalelwe inethiwekhi yangaphakathi.
I-TLS yokuphela kokuphela ingumkhawulo walokho kubonakala. Lapho iklayenti liqinisekisa isitifiketi seseva yedathabheyisi, idivayisi yokuhlola icubungula uxhumano kodwa ayikwazi ukufunda umthwalo wohlelo lokusebenza, ngakho ukutholwa lapho kuhambisana nemethadatha hhayi umbhalo wombuzo. Uma weqa leyo mininingwane, wonke uxhumano oluvinjiwe luzobonakala njengobufakazi bokuhlola okujulile. Womabili amaqiniso abalulekile: idivayisi ayiyona impumputhe, futhi ayifundi konke.
Ukutholwa akusona isiphumo esingamanga ngokuzenzakalela
Isiginesha sikhona ukuze sibambe iphethini, futhi ithrafikhi yebhizinisi elindelekile isengadlula endleleni yekhodi esengozini ngempela. Qala ngokufanisa umcimbi oqoshiwe nomsebenzi wohlelo lokusebenza: isigxivizo sesikhathi, umthombo nendawo okuyiwa kuyo yangaphakathi, izimbobo, isihlonzi sesiginesha kanye isinyathelo esithathiwe. Lezo zinkambu eziyisithupha zikutshela nokuthi isixwayiso singesoxhumano olwehlulekile noma singesomakhelwane owayematasa ngengozi.
Ukufika kwamaphakethe ambalwa kuseva akukhombisi i-IPS njengembangela, futhi isiginesha esifanayo asibufakazi bokuthi iklayenti lisemthethweni. Kokubili ukufunda kuyizilinganiso kuze kuhlotshaniswe umcimbi nombiko weklayenti ngokwalo. Umcimbi ohlotshanisiwe uwubufakazi, futhi inguqulo yedathabheyisi iyingxenye yesinqumo.
Izindawo ezintathu zokuhlukile nokuthi ngayinye isusa ini
Izinketho ziyahluka ngokuthi zivala ukuhlola okungakanani, futhi umehluko mkhulu kunalokho okusikiselwa isixhumanisi sesilungiselelo. Ukucindezelwa kwesiginesha kususa umthetho owodwa wethrafikhi efanayo. Ukukhishwa komthombo kususa ukuhlolwa kwakho konke okuvela kulelo kheli. Ukukhutshazwa kwesigaba kususa umndeni wemithetho, kwesinye isikhathi kuyo yonke inqubomgomo.

Khetha umugqa wokuqala noma nini lapho umkhiqizo ungakubeka. Uma ungakwazi, nyusela phezulu umkhawulo esikhundleni sokwethula ukuhlukile okubanzi njengokunembile; umuntu okugunyazayo kufanele abone umehluko ngokubhaliwe.
Ububanzi ocabanga ukuthi ububekile
Ukuhumusha kushintsha lokho ukuhlukile okukuhlanganisayo. Lapho amaklayenti amaningi e-VPN evela ngemuva kwekheli elilodwa elihunyushiwe, ukukhishwa kwalelo kheli kuwakhulula wonke, okubanzi kakhulu kunokutholakala okukodwa okuqale uphenyo.
Hlola ububanzi obusebenzayo hhayi ifomu oliligcwalisa, futhi qopha isihlonzi somcimbi eceleni komthetho. Ukuhlukile okungenasizathu kuba inqubomgomo unomphela, futhi umbuyekezi olandelayo akanayo indlela yokwazi ukuthi kusasebenza yini.
Hlola kabusha umsebenzi kanye nomngcele
Phinda umsebenzi wedathabheyisi ongenabungozi futhi uqinisekise ukuthi uxhumano luyaphela, bese uqinisekisa ukuthi ukutholwa okungahlobene kusasebenza esivivinyweni okufanele kukugqoze. Ukubuyisela ukuxhumana kuyindinganiso yokwamukela eyodwa; ukugcina umngcele ohlosiwe kungenye.

Ukucindezelwa okufundwa kabusha ngokuhleliwe kuyisinqumo sobunjiniyela; lokho okungekho muntu okukhumbulayo ukwanda okunensayo komngcele wokwethemba.
