I-DMZ - yintoni na kwaye isebenza ngayo

Kwinqaku lethu, siya kuqwalasela umxholo we-DMZ. Makhe sizame ukuphendula imibuzo malunga nokuba yiyiphi i-DMZ, indlela yabonakala ngayo, nendlela yokuseka iDMZ. Wonke umntu uya kukwazi ukuqokelela ubuncinane ulwazi olubanzi malunga nesi sihloko.

Izizathu zeendawo ezidityanisiweyo

Ngoku kuncinci ukungazibona nayiphi na iinkampani ngaphandle kweekhomputha. Kwaye kukho iikhomputha, kukho inethiwekhi yendawo yangaphakathi edibanisa.

Ubuninzi bomnatha wendawo wangaphakathi lusebenza kwaye lukhuselekile ngokwalo. Kodwa ngokuza kwe-Intanethi yehlabathi, yonke into ibe yinkimbinkimbi. Ngoku ininzi yeenkampani zisebenzisa i-WebWide Web. Oku kunceda kakhulu ukuhamba komsebenzi, njengoko wonke umntu angayifumana nayiphi na inkcazelo yomdla kumcimbi wemizuzwana.

Kodwa ngokuphuhliswa kwe-Intanethi kwakukho isongelo lokungena kwinethiwekhi jikelele yenkampani evela ngaphandle. Okokuqala, ibandakanye iinkampani ezinenkonzo zentanethi, ezifumanekayo kunoma yimuphi umsebenzisi weWebhu Yehlabathi. Ingozi yukuthi umhlaseli, onokufikelela kwi-web service, unokufumana ulwazi oluthile olugcinwe kuyo nayiphi na iikhomputha ezixhunyiwe kwinethiwekhi yangaphakathi. Oku kubangela ubunzima beqela, ezixazululwa ngokudala i-DMZ.

Umthombo wo kuqala

Into yokuqala ekufuneka ikwazi malunga ne-DMZ kukuba, okokuqala, lixesha lezempi, elivela kwingcamango "yendawo yokudityaniswa kwemimandla". Ithetha inxalenye ethile yommandla ophakathi kwamazwe amabini aphikisayo. Ithintela nawuphi na uhlobo lomsebenzi wemikhosi -kuba kube ngumsebenzi okhethekileyo, ukuphambukisa okanye ubuqili.

I-DMZ yendawo yokuhlengahlengiswa kwemimandla: ubugcisa kunye nokuphunyezwa

Ukususela ekuchazeni kwekota yokuqala, kuyacaca ukuba i-DMZ iyinxalenye ethile yomhlaba apho kukho nawuphi na uhlobo lomsebenzi onobungozi onqatshelwe. Kwaye oku kuphumelela kakhulu kubonakalisa yonke into ebalulekileyo yale nto, masithi, amaqhinga.

Simele siqonde ingcamango yeDMZ, isisombululo esilula kakhulu, oko kukudala inxalenye ehlukeneyo yenethiwekhi yecomputer engabandakanywa kuyo yonke indawo yangaphandle yokusingatha iInternet kunye ne-intanethi yangaphakathi yenkampani. Kwakhona lo mqathango wokulawula okanye ukuthintela ngokupheleleyo ukufikelela kwi-Intanethi kunye nenethiwekhi yangaphakathi.

Yakha isahlulo esahlukileyo senethiwekhi kulula ngokwaneleyo. Kule nto, iifutha-mlilo okanye izitshixo zomlilo zisetyenzisiweyo. Leli gama elithi "firewall" kumsebenzisi oqhelekileyo lingaziwa kwiifilimu malunga nabaqhwitha abaziwayo, kodwa bambalwa kakhulu abantu abazi ukuba uyintoni.

I-firewall iyisundiyo yesofthiwe kunye neofthiwe yekhomputha yecomputer eyahlula kumacandelo kwaye ivumela ukucoca inethiwekhi yendlela yokungena engenayo ngokwemigaqo echazwe ngumsebenzisi (umlawuli). Kwakhona, xa kungenako ukungagunyaziswa okungagunyaziswanga, umhlaseli ufumana ukufikelela kwezo fayile ezitholakala kwicandelo elihlukileyo, ngaphandle kokungabikho komnye umntu.

Kukho ubuncinane iindidi ezimbini zokuqulunqwa kwemimandla edityanisiweyo - kunye ne-firewall enye okanye ezininzi. Ekuqwalaselweni kokuqala, i-firewall idibanisa inethiwekhi kumacandelo amathathu:

• Inethwekhi yangaphakathi;
• DMZ;
• Isitellite

Kodwa kunjalo, le ndlela inika inqanaba elaneleyo lokukhusela. Kwiinkampani ezininzi ezininzi, indlela yesibini isasetyenziswa - kunye nenani elikhulu lomlilo. Kule meko, umhlaseli uya kufuneka anqobe ubuncinane enye inkqubo ye-perimeter kunye nesihlunu sakhe sendlela, okwandisa kakhulu ukhuseleko.

Yenza ngokwezifiso

Ngokuqinisekileyo, abaninzi baye bafuna ngokufanelekileyo malunga ne-DMZ, ukuba le yindlela elula kwaye efanelekileyo yokuqinisekisa ukhuseleko lwenethiwekhi yakho yekhompyutha. Abasebenzisi bee-intanethi zee-intanethi zee-intanethi bangakwazi ukuvavanya lobu buchule bobuqhetseba bebacuki.

Yonke into efunekayo ukulungiselela i-DMZ kukuvelisa idivaysi enye njengomnatha wendawo, ukuxhuma, ngokulandelanayo, ngokusebenzisa intambo eyahlukileyo kwisixokelelwano samahhala se-router, ize uyinike yona idilesi ye-static IP, kwaye uyisebenze kwi window ye-DMZ uze uqalise kwakhona isixhobo.

Ngaphambi kwayo yonke imigaqo, kufuneka uqinisekise ukuba zonke izixhobo zinokukhuselwa kwangoku. Emva koko, unokusebenzisa ngokukhululekileyo le nto kodwa elula, kodwa ekhuselekileyo yokukhusela ukudibanisa idatha yakho.

Eli nqaku lichazwe ngokufutshane zonke iinkcukacha ezibalulekileyo malunga ne-DMZ: oko kukuthi, kusebenza njani, kwaye, kubaluleke kakhulu, injongo yayo.
