Njengoko igagasi le-Industry 4.0 kunye ne-Industrial Internet of Things (IIoT) lisasazeka kwihlabathi liphela, ukudibana kwe-Operational Technology (OT) kunye ne-Information Technology (IT) akunakuphikiswa. Nangona oku kudibana kuzisa imveliso engakaze ibonwe ngaphambili kunye nokuqonda idatha, kukwaphula intsomi "yokwahlulwa ngokwasemzimbeni" kweeNkqubo zoLawulo lwezeMveliso zemveli (ICS), ziveza uthungelwano lwemveliso olubalulekileyo kwizisongelo ze-cyber ezintsonkothileyo.
Njengenkokeli eneminyaka elikhulu ubudala kwizisombululo zothutho lwemiqondiso kunye nenethiwekhi yemizi-mveliso, uBelden ukholelwa ukuba isisombululo esisisiseko sale ngxaki asikokuyenza nje "ibe yipatch" inkqubo emva kokwakhiwa kwayo, kodwa kukubuyela kwiziseko-ukufaka nzulu imigaqo yokhuseleko ukusuka kwinqanaba lokuqala loyilo lweziseko, ukwakha ukhuselo oluqinileyo olunezakhono zokhuseleko ezisisiseko.
Imingeni Eyodwa Yokhuseleko lwe-OT: Kutheni Amaqhinga Okhuseleko lwe-IT Engenakulungiswa Ngokuthe Ngqo?
Ngaphambi kokuba sixoxe ngezisombululo, kufuneka siqonde ngokucacileyo ukuba imeko-bume ye-OT yahlukile. Ngokungafaniyo neendawo ze-IT ezibeka phambili "ubumfihlo" bedatha, iimfuno eziphambili zendawo ye-OT kukuveliswa "kokufumaneka" kunye "nokuqhubeka." Naliphi na ixesha lokungasebenzi elibangelwa kukungaqini kakuhle kwamanyathelo okhuseleko linokubangela ilahleko yezoqoqosho yezigidi okanye iingozi zokhuseleko.
Iinethiwekhi ze-OT zijongene nemingeni eyahlukileyo:
Ukufumaneka kubaluleke kakhulu: Uhlaziyo lokhuseleko okanye ukuskena akufuneki kuphazamise iinkqubo zemveliso.
Iinkqubo eziqhelekileyo zemveli: Inani elikhulu lezixhobo ezineminyaka emininzi ubudala (ii-PLC, ii-HMI) azixhasi iiprotokholi zanamhlanje zokubethela kwaye azinakulungiswa.
Iiprotokholi zobunini: Iiprotokholi zoshishino (ezifana neModbus TCP, EtherCAT, EtherNet/IP, PROFINET) azizange ziyilwe kucingelwa ukhuseleko kwaye zisengozini yokuhlaselwa.
Iindawo ezinobungozi: Izixhobo mazisebenze ngokuzinzileyo kumaqondo obushushu aphezulu, ukufuma, kunye neemeko zokungcangcazela.
Ngoko ke, ukuphinda nje amaqhinga okhuseleko lwe-IT kwicandelo le-OT akunamsebenzi. Izisombululo zokhuseleko kufuneka zilungelelaniswe ngokunzulu neemfuno ezithile ze-OT.
UBelden Hirschmann: Ukwakha iziseko zokhuseleko ezivela kwisithathu
Umaleko 1: Iindawo kunye neeConduits – Ukwahlulwa kweNethiwekhi Eqinileyo
Le yintsika yokhuseleko lwenethiwekhi yemizi-mveliso. Ngokwahlulahlula inethiwekhi kwiindawo ezahlukeneyo zokhuseleko (iiNdawo), ezifana neendawo zolawulo, iindawo zokubeka esweni, kunye neendawo zokuphumeza imveliso, kunye nokunciphisa unxibelelwano phakathi kweendawo ukuya kwiindlela ezichazwe ngokucacileyo, intshukumo esecaleni yezisongelo inokunciphisa ngempumelelo. Nokuba indawo isengozini, umonakalo unokuncitshiswa ube mncinci. Uqheliso lukaBelden: UBelden'sHirschmannUthotho lwe-industrial switch lubonelela ngesiseko sehardware esiqinileyo nesithembekileyo sokwakha imodeli ecacileyo "yeendawo kunye nee-conduits" ngokusebenzisa ukwahlulwahlulwa okunamandla kwe-VLAN (Virtual Local Area Network), ii-Access Control Lists (ii-ACL), kunye nolawulo lwezibuko ezi-granular. Iqinisekisa ukuba kuphela ithrafikhi egunyazisiweyo enokuhamba phakathi kweendawo zamanqanaba okhuseleko ahlukeneyo.
Umaleko 2: Ukhuseleko lweMida – "Abagcini-masango abaLungileyo kwiMizi-mveliso" abakrelekrele
Emva kokwahlulahlula inethiwekhi ibe ziindawo, umda wendawo nganye udinga "umgcini-sango" onamandla ukwenza uhlolo oluqinileyo lokhuseleko. Oku akukokuthintela nje ithrafikhi ngokulula, kodwa kufuna ukhuseleko olukrelekrele oluqonda ulwimi lwemizi-mveliso. Uqheliso lukaBelden: Iifirewall zokhuseleko lwemizi-mveliso zochungechunge lweEagle zingundoqo kolu luhlu. Ayisiyo nje ifirewall; yingcali yeDeep Packet Inspection (DPI) eyenzelwe ngokukodwa iindawo ze-OT. Ingaqonda "" iiprotokholi zemizi-mveliso ezifana neModbus TCP, EtherNet/IP, kunye ne-OPC, ivumela kuphela imiyalelo esemthethweni ehambelana nemithetho esekiweyo, ngelixa ilahla naziphi na iipakethi zomyalelo ezingaqhelekanga okanye ezinobungozi, ibonelela ngokhuseleko kwii-PLC ezisengozini ezingenakulungiswa.
Umaleko wesithathu: Ukuqina kwenethiwekhi kunye nokubonakala kwayo–
Ukuqinisekisa Ukusebenza Okuqhubekayo kunye Nokuphendula Okukhawulezileyo Isiseko sokhuseleko kukuzinza. Inethiwekhi ehlala iphuma kwaye ingasebenzi kakuhle yiyo eyona mngcipheko mkhulu wokhuseleko. Ngaphezu koko, awunakukhusela into ongayiboniyo. Ukuqonda ngokucacileyo inethiwekhi yonke kuyimfuneko yokuzikhusela ngokukhawuleza kunye nokuphendula ngokukhawuleza.
Iindlela zikaBelden: Ukuqina kwehardware: Iintambo zikaBelden, izihlanganisi, kunye neeswitshi zemizi-mveliso zenzelwe iimeko zoshishino ezinzima, zinokumelana okuhle kakhulu nokuphazamiseka kwe-electromagnetic, ububanzi bobushushu bokusebenza, kunye nokuthembeka okuphezulu, okuqinisekisa ukufumaneka konxibelelwano lwenethiwekhi kwinqanaba elibonakalayo.
Ukubonakala kweNethiwekhi:HirschmannIsoftware yolawulo lwenethiwekhi ye-Industrial HiVision inokuzifumana ngokuzenzekelayo zonke izixhobo kwinethiwekhi, ibonelele ngembonakalo yexesha langempela ye-topology yenethiwekhi kunye nemeko yempilo. Inkqubo iya kukhupha isilumkiso ngoko nangoko xa ukufikelela kwesixhobo okungagunyaziswanga okanye ukusilela kwekhonkco, ivumela abalawuli benethiwekhi ukuba baqonde imeko kwaye baphendule ngokukhawuleza.
Ukhuseleko luyilwe ngaphakathi, alufakwanga. Ukhuseleko lwenethiwekhi yemizi-mveliso ludabi lexesha elide; akukho nto ilungileyo. Nangona kunjalo, inethiwekhi enoyilo lokhuseleko olusetyenziswa kwinqanaba leziseko zophuhliso iya kuba namandla ngakumbi kwiingozi kuneenkqubo ezixhomekeke kwisoftware yokhuseleko eyongezelelweyo.
Imbono kaBelden icacile kwaye ayigungqi: ukhuseleko alufanele lube yinto ebiza kakhulu emva koko, kodwa luphawu oluphambili lwenethiwekhi. Ngokudibanisa imigaqo efana nokwahlulwa kwendawo, ukhuseleko olujikeleze ummandla, ukuqina kwenethiwekhi, kunye nokubonakala ngokupheleleyo kuyo yonke into esisiseko—iiswitshi, iingcango, iintambo, kunye nesoftware yolawulo—sinokwakha ngokwenene ukhuselo oluqinileyo kubathengi bethu olunokumelana nezisongelo zangaphandle ngelixa siqinisekisa imisebenzi yemveliso yangaphakathi ezinzileyo, ngaloo ndlela ibenza bakwazi ukuhamba ngesantya sotshintsho lwedijithali ngokuthe ngcembe nangokuzinzileyo.
