Kwimeko yanamhlanje edityanisiweyo yemizi-mveliso, imfuneko yamanyathelo okhuseleko oluqilima kwi-cybersecurity ayizange ibe nkulu. Njengoko itekhnoloji yedijithali iya idityaniswa ngakumbi kwiinkqubo zoshishino, umngcipheko wezoyikiso ze-cyber kunye nokuhlaselwa kwanda kakhulu. Ke ngoko, ukuqinisekisa ukhuseleko lothungelwano lwemizi-mveliso kuye kwaba yeyona nto iphambili kwimibutho kuwo onke amashishini. Icandelo eliphambili lokukhusela uthungelwano lwamashishini kukusetyenziswa kokutshintsha kwe-Ethernet yeshishini, edlala indima ephambili ekuphuculeni ukhuseleko lwenethiwekhi.
Ukutshintsha kwe-Industrial Ethernet zixhobo zenethiwekhi ezikhethekileyo ezenzelwe ukuququzelela unxibelelwano kunye nokudluliselwa kwedatha kwiindawo zoshishino. Ngokungafaniyo nokutshintsha kwe-Ethernet yemveli, iiswitshi ze-Ethernet zemizi-mveliso ziyilelwe ukumelana neemeko ezirhabaxa eziqhelekileyo kwindawo yemizi-mveliso, efana nobushushu obugqithisileyo, ukufuma, kunye nokuphazamiseka kombane. Olu tshintsho lwenza umqolo wothungelwano lwemizi-mveliso, ukuhambisa idatha ngokungenamthungo nangokuthembekileyo phakathi kwezixhobo eziqhagamshelweyo ezifana nezilawuli zengqiqo ezicwangcisiweyo (PLCs), ujongano lomatshini woluntu (HMIs) kunye nezinye izixhobo ezibalulekileyo zoshishino.
Xa kuziwa kukhuseleko lwe-cybersecurity, iiswitshi ze-Ethernet zemizi-mveliso ngumgca obalulekileyo wokuzikhusela ngokuchasene nezoyikiso ezinokubakho kunye nokuba sesichengeni. Olu tshintsho luxhotyiswe ngeempawu zokhuseleko eziphezulu ezinceda ukunciphisa umngcipheko wokufikelela okungagunyaziswanga, ukwaphulwa kwedatha, kunye nolunye uhlaselo lwe-cyber. Enye yezinto eziphambili zokhuseleko ezinikezelwa yi-industrial Ethernet switches yi-port-based access control, evumela abalawuli benethiwekhi ukuba bathintele ukufikelela kumachweba athile enethiwekhi ngokusekelwe kwiikhrayitheriya ezichazwe kwangaphambili. Oku kunceda ukuthintela izixhobo ezingagunyaziswanga ekufikeleleni kuthungelwano lwamashishini, ukunciphisa ukubakho kokwaphulwa kokhuseleko.
Ukwengeza,iiswitshi Ethernet yamashishiniinkxaso yeteknoloji ye-LAN (VLAN) enenyani, enokwahlula inethiwekhi ibe yi-subnets ekwanti ezininzi. Ngokwenza ii-VLAN ezahlukileyo zezixhobo ezahlukeneyo zoshishino kunye neenkqubo, imibutho inokuqulatha izoyikiso zokhuseleko ezinokubakho kunye nokunciphisa impembelelo yokuphulwa kokhuseleko. Olu lwahlulo lukwanceda ukulawula itrafikhi yothungelwano kunye nokuthintela izixhobo ezingagunyaziswanga ekubambiseni idatha ebuthathaka.
Ukongeza kulawulo lokufikelela kunye nokwahlulahlulwa kwenethiwekhi, iinguqu ze-Ethernet zeshishini zibonelela ngezakhono eziqinileyo zokubethela ukuqinisekisa ukhuseleko lokuhanjiswa kwedatha yenethiwekhi. Ngokuxhasa iiprothokholi ezifana ne-Secure Sockets Layer (SSL) kunye noKhuseleko lweNgqungquthela yezoThutho (TLS), iiswitshi ze-Ethernet zamashishini ziqinisekisa ukuba idatha yotshintshiselwano phakathi kwezixhobo ezixhunyiwe zifihliweyo, okwenza kube lula kubahlaseli be-cyber ukuba babambe kwaye bachaze ulwazi olubucayi. umngeni.
Ukongezelela, iinguqu ze-Ethernet zemizi-mveliso zenzelwe ukubonelela ukujonga ixesha langempela kunye nokubonakala kwetrafikhi yenethiwekhi, ukuvumela abalawuli ukuba babone ngokukhawuleza kwaye baphendule kwiziganeko ezinokuthi zikhuseleke. Ngokusebenzisa iimpawu ezifana nesipili sezibuko kunye nokujongwa kwetrafikhi, imibutho inokufumana ulwazi malunga nomsebenzi wothungelwano kwaye ichonge nakuphi na ukuziphatha okungaqhelekanga okanye okukrokrisayo okunokubonisa isoyikiso sokhuseleko.
Njengoko uthungelwano lwamashishini luqhubeka nokuphuhlisa kwaye lwanda, indima yokutshintsha kwe-Ethernet yeshishini kukhuseleko lwenethiwekhi iya kubaluleka ngakumbi. Njengoko itekhnoloji yokusebenza (OT) kunye neenkqubo zetekhnoloji yolwazi (IT) zidibana, imfuno yezisombululo ezihlanganisiweyo zokhuseleko lwe-cybersecurity ezigubungela iindawo zombini ziyafuneka. Iiswitshi ze-Industrial Ethernet zikulungele kakuhle ukujongana nemiceli mngeni ekhethekileyo yokhuseleko lwe-cyber ejongene neemeko zemizi-mveliso kunye neempawu zabo zokhuseleko lobuchwephesha kunye noyilo olubi.
Ukuququmbela,Iiswitshi Ethernet Industrialdlala indima ephambili ekukhuseleni uthungelwano lwemizi-mveliso kwizoyikiso ze-cyber. Ukutshintsha kwe-Industrial Ethernet kunceda imibutho yomeleze ukhuseleko lwabo kwaye ikhusele i-asethi ebalulekileyo yezoshishino ngokuphumeza amanyathelo okhuseleko oluqinileyo njengolawulo lokufikelela, ulwahlulo lwenethiwekhi, i-encryption, kunye nokubeka iliso ngexesha langempela. Njengoko uthungelwano lwemizi-mveliso luqhubeka lufakwa kwidijithali kwaye luqhagamshelwe, ukwamkelwa kokutshintsha kwe-Ethernet yeshishini kubalulekile ekwakheni isiseko soshishino esinamandla nesikhuselekileyo.
