Ezimweni zanamuhla zezimboni ezixhumene, isidingo sezinyathelo eziqinile zokuphepha ku-inthanethi asikaze sibe sikhulu. Njengoba ubuchwepheshe bedijithali bukhula buhlanganiswe nezinqubo zezimboni, ubungozi bokusongelwa nokuhlaselwa kwe-inthanethi bukhula kakhulu. Ngakho-ke, ukuqinisekisa ukuphepha kwamanethiwekhi ezimboni sekuyinto ehamba phambili ezinhlanganweni kuzo zonke izimboni. Ingxenye ebalulekile yokuvikela amanethiwekhi ezimboni ukusetshenziswa kwamaswishi e-Ethernet yezimboni, adlala indima ebalulekile ekuthuthukiseni ukuphepha kwenethiwekhi.
Amaswishi e-Industrial Ethernet angamadivayisi enethiwekhi akhethekile aklanyelwe ukwenza lula ukuxhumana nokudluliswa kwedatha ezindaweni zezimboni. Ngokungafani nokushintsha kwe-Ethernet yendabuko, amaswishi e-Ethernet yezimboni aklanyelwe ukumelana nezimo ezinzima ezivamile ezindaweni zezimboni, ezifana nezinga lokushisa elidlulele, umswakama, nokuphazamiseka kazibuthe kagesi. Lezi zinguquko zakha umgogodla wamanethiwekhi ezimboni, ziletha idatha ngaphandle komthungo nangokwethembeka phakathi kwamadivayisi axhunyiwe njengezilawuli ze-programmable logic (PLCs), ukuxhumana kwemishini yabantu (ama-HMI) nezinye izisetshenziswa ezibucayi zezimboni.
Uma kukhulunywa nge-cybersecurity, ukushintshwa kwe-Ethernet yezimboni kuwumugqa obalulekile wokuzivikela ezinsongweni ezingaba khona nokuba sengozini. Lezi zinguquko zifakwe izici zokuphepha ezithuthukisiwe ezisiza ukwehlisa ubungozi bokufinyelela okungagunyaziwe, ukuphulwa kwedatha, nokunye ukuhlasela kwe-inthanethi. Esinye sezici ezibalulekile zokuphepha ezinikezwa amaswishi e-Ethernet yezimboni ukulawula ukufinyelela okusekelwe embobeni, okuvumela abaphathi benethiwekhi ukuthi bakhawulele ukufinyelela kumachweba athile enethiwekhi ngokusekelwe kumibandela echazwe ngaphambilini. Lokhu kusiza ukuvimbela amadivayisi angagunyaziwe ukuthi afinyelele amanethiwekhi ezimboni, kunciphisa amathuba okuphulwa kwezokuphepha.
Ngaphezu kwalokho,ukushintshwa kwe-Ethernet yezimboniisekela ubuchwepheshe be-virtual LAN (VLAN), obungahlukanisa inethiwekhi ibe ama-subnet ahlukene amaningi. Ngokwakha ama-VLAN ahlukene emishini nezinhlelo zezimboni ezahlukene, izinhlangano zingaqukatha izinsongo zokuphepha ezingaba khona futhi zikhawulele umthelela wokuphulwa kwezokuphepha. Lesi segimenti futhi sisiza ukulawula ithrafikhi yenethiwekhi futhi kuvimbele amadivayisi angagunyaziwe ekubambeni idatha ebucayi.
Ngokungeziwe ekulawuleni ukufinyelela nokuhlukaniswa kwenethiwekhi, ukushintshwa kwe-Ethernet yezimboni kunikeza amandla okubethela aqinile ukuze kuqinisekiswe ukuphepha kokudluliswa kwedatha yenethiwekhi. Ngokusekela amaphrothokholi afana ne-Secure Sockets Layer (SSL) kanye ne-Transport Layer Security (TLS), amaswishi e-Ethernet yezimboni aqinisekisa ukuthi idatha eshintshwayo phakathi kwamadivayisi axhunyiwe iyabethelwa, okwenza kube lula kubahlaseli be-inthanethi ukuthi babambe futhi bahlukanise ulwazi olubucayi. inselele.
Ukwengeza, amaswishi e-Ethernet yezimboni aklanyelwe ukuhlinzeka ngokuqapha kwesikhathi sangempela kanye nokubonakala kwethrafikhi yenethiwekhi, okuvumela abaphathi ukuthi bathole ngokushesha futhi baphendule izehlakalo zokuphepha ezingaba khona. Ngokusebenzisa izici ezifana ne-port mirroring nokuqapha ithrafikhi, izinhlangano zingathola imininingwane ngomsebenzi wenethiwekhi futhi zihlonze noma yikuphi ukuziphatha okungajwayelekile noma okusolisayo okungase kubonise usongo lokuvikeleka.
Njengoba amanethiwekhi ezimboni eqhubeka nokukhula futhi anda, indima yokushintshwa kwe-Ethernet yezimboni ekuvikelekeni kwenethiwekhi izobaluleka kakhulu. Njengoba ubuchwepheshe obusebenzayo (OT) kanye nezinhlelo zobuchwepheshe bolwazi (IT) zihlangana, isidingo sezisombululo ezididiyelwe zokuvikeleka ku-inthanethi ezihlanganisa zombili lezi zindawo siyabaluleka. Amaswishi e-Industrial Ethernet afaneleka kahle ukubhekana nezinselele eziyingqayizivele ze-cybersecurity ezibhekene nezimo zezimboni ezinezici zazo zokuphepha ezichwepheshile kanye nomklamo omangelengele.
Ekuphetheni,Ukushintshwa kwe-Industrial Ethernetdlala indima ebalulekile ekuvikeleni amanethiwekhi ezimboni ekusongelweni kwe-inthanethi. Amaswishi e-Industrial Ethernet asiza izinhlangano ukuthi ziqinise ukuzivikela futhi zivikele izimpahla ezibucayi zezimboni ngokusebenzisa izinyathelo zokuphepha eziqinile njengokulawula ukufinyelela, ukuhlukaniswa kwenethiwekhi, ukubethela, nokuqapha kwesikhathi sangempela. Njengoba amanethiwekhi ezimboni eqhubeka ukwenziwa idijithali futhi axhumeke, ukwamukelwa kwamaswishi e-Ethernet yezimboni kubalulekile ekwakheni ingqalasizinda yezimboni eqinile nevikelekile.
