Njengoba igagasi le-Industry 4.0 kanye ne-Industrial Internet of Things (IIoT) lisakazeka emhlabeni wonke, ukuhlangana kwe-Operational Technology (OT) kanye ne-Information Technology (IT) akunakulungiseka. Nakuba lokhu kuhlangana kuletha umkhiqizo kanye nokuqonda kwedatha okungakaze kubonwe, futhi kuqeda inganekwane "yokuhlukaniswa ngokomzimba" kwe-Industrial Control Systems (ICS) yendabuko, okuveza amanethiwekhi okukhiqiza abalulekile ezinsongweni ze-cyber eziyinkimbinkimbi kakhulu.
Njengomholi wekhulu leminyaka ekuxazululeni izixazululo zokudlulisa isignali kanye nenethiwekhi yezimboni, uBelden ukholelwa ukuthi ikhambi eliyisisekelo lale nselele akukhona nje "ukulungisa" uhlelo ngemva kokwakhiwa kwalo, kodwa kunalokho ukubuyela ezisekelweni - ukufaka ngokujulile izimiso zokuphepha kusukela esigabeni sokuqala sokuklama ingqalasizinda, ukwakha ukuzivikela okuqinile okunekhono lokuphepha elingokwemvelo.
Izinselele Eziyingqayizivele Zokuphepha Kwe-OT: Kungani Amasu Okuphepha Kwe-IT Engenakuguqulwa Ngokuqondile?
Ngaphambi kokuxoxa ngezixazululo, kumele siqaphele ngokucacile ukuhluka kwendawo ye-OT. Ngokungafani nendawo ye-IT ebeka phambili "ubumfihlo bedatha," izidingo eziyinhloko zendawo ye-OT "ukutholakala" kokukhiqiza kanye "nokuqhubeka." Noma yisiphi isikhathi sokungasebenzi esibangelwa izinyathelo zokuphepha ezinganele singaholela ezigidini zamaRandi ekulahlekelweni kwezomnotho noma ngisho nasezingozini zokuphepha.
Amanethiwekhi e-OT abhekene nezinselele ezihlukile:
Ukutholakala kubaluleke kakhulu: Izibuyekezo zokuphepha noma ukuskena akumele kuphazamise izinqubo zokukhiqiza.
Izinhlelo ezivamile zesikhathi esidlule: Inani elikhulu lamadivayisi aneminyaka eminingi (ama-PLC, ama-HMI) awasekeli amaphrothokholi okubethela anamuhla futhi awakwazi ukushintshwa.
Izinqubo zobunikazi: Izinqubo zobunikazi (ezifana ne-Modbus TCP, i-EtherCAT, i-EtherNet/IP, i-PROFINET) aziklanywanga kucatshangelwa ukuphepha futhi zisengozini yokuhlaselwa.
Izindawo ezibucayi: Imishini kumele isebenze kahle emazingeni okushisa aphezulu, umswakama, kanye nezimo zokudlidliza.
Ngakho-ke, ukuphinda amasu okuphepha kwe-IT emkhakheni we-OT akulungile. Izixazululo zokuphepha kumele zivumelane ngokujulile nezidingo ezithile ze-OT.
UBelden Hirschmann: Ukwakha Ingqalasizinda Yezokuphepha Kusukela Kumathathu
Isigaba 1: Izindawo Nemifudlana – Ukuhlukaniswa Kwenethiwekhi Eqinile
Lokhu kuyitshe lesisekelo sokuphepha kwenethiwekhi yezimboni. Ngokuhlukanisa inethiwekhi ibe yizindawo zokuphepha ezahlukene (izindawo), njengezindawo zokulawula, izindawo zokuqapha, kanye nezindawo zokwenza umkhiqizo, kanye nokunciphisa ukuxhumana phakathi kwezindawo kuya emihubheni echazwe ngokucacile, ukunyakaza kwezinhlangothi zezinsongo kungancishiswa ngempumelelo. Ngisho noma indawo isengozini, umonakalo ungancishiswa ube mncane kakhulu. Umkhuba kaBelden: UBelden'sUHirschmannUchungechunge lwezinkinobho zezimboni luhlinzeka ngesisekelo sehadiwe esiqinile nesithembekile sokwakha imodeli "yezindawo namapayipi" ecacile ngokusebenzisa ukuhlukaniswa okunamandla kwe-VLAN (Virtual Local Area Network), Uhlu Lokulawula Ukufinyelela (ama-ACL), kanye nokuphathwa kwe-granular port. Luqinisekisa ukuthi ithrafikhi egunyaziwe kuphela engahamba phakathi kwezindawo zamazinga okuphepha ahlukene.
Isigaba 2: Ukuvikelwa Kwemingcele – "Abagcini Bamasango Abasezingeni Lezimboni" Abahlakaniphile
Ngemva kokuhlukanisa inethiwekhi ibe yizindawo, umngcele wendawo ngayinye udinga "umlindi wesango" onamandla ukuze enze ukuhlolwa okuqinile kokuphepha. Lokhu akugcini nje ngokuvimbela ithrafikhi, kodwa kudinga ukuvikelwa okuhlakaniphile okuqonda ulimi lwezimboni. Umkhuba kaBelden: Uchungechunge lwe-Eagle lwezingodo zokuvikela izimboni ziyisisekelo salolu ngqimba. Akuyona nje i-firewall; uchwepheshe we-Deep Packet Inspection (DPI) oklanyelwe ngqo izindawo ze-OT. "Ingaqonda" izinqubo zezimboni ezifana ne-Modbus TCP, i-EtherNet/IP, ne-OPC, ivumela kuphela imiyalo esemthethweni ehambisana nemithetho esethiwe, ngenkathi yenqaba noma yimaphi amaphakethe emiyalo angajwayelekile noma anonya, enikeza ukuvikelwa kwama-PLC asengozini angenakushintshwa.
Isendlalelo sesithathu: Ukuqina Kwenethiwekhi Nokubonakala–
Ukuqinisekisa Ukusebenza Okuqhubekayo Nokuphendula Okusheshayo Isisekelo sokuphepha ukuzinza. Inethiwekhi evame ukwehla futhi ingasebenzi kahle iyona ingozi enkulu yokuphepha. Ngaphezu kwalokho, awukwazi ukuvikela lokho ongakwazi ukukubona. Ukuqonda okucacile kwenethiwekhi yonke kuyimfuneko yokuzivikela okusheshayo nokuphendula okusheshayo.
Imikhuba kaBelden: Ukuqina Kwehadiwe: Izintambo zikaBelden, izixhumi, kanye nezinkinobho zezimboni zenzelwe izindawo zezimboni ezinzima, zinokumelana okuhle kakhulu nokuphazamiseka kwe-electromagnetic, izinga lokushisa elibanzi lokusebenza, kanye nokuthembeka okuphezulu, okuqinisekisa ukutholakala kokuxhumeka kwenethiwekhi ezingeni elibonakalayo.
Ukubonakala Kwenethiwekhi:UHirschmannIsofthiwe yokuphatha inethiwekhi ye-Industrial HiVision ingathola ngokuzenzakalelayo wonke amadivayisi kunethiwekhi, inikeze umbono wesikhathi sangempela we-topology yenethiwekhi kanye nesimo sempilo. Uhlelo luzokhipha isaziso ngokushesha lapho ukufinyelela kwedivayisi okungagunyaziwe noma ukwehluleka kwesixhumanisi, okuvumela abaphathi benethiwekhi ukuthi baqonde isimo futhi baphendule ngokushesha.
Ukuphepha kuklanywe ngaphakathi, hhayi okungeziwe. Ukuphepha kwenethiwekhi yezimboni kuyimpi yesikhathi eside; akukho nzuzo. Kodwa-ke, inethiwekhi enomklamo wokuphepha osetshenziswa ezingeni lengqalasizinda izoba namandla kakhulu ezingozini kunezinhlelo ezithembele kusofthiwe yokuphepha eyengeziwe.
Umbono kaBelden ucacile futhi awuguquki: ukuphepha akufanele kube yinto ebizayo kamuva, kodwa kube yisici esiyinhloko senethiwekhi. Ngokuhlanganisa izimiso ezifana nokuhlukaniswa kwendawo, ukuvikelwa komngcele, ukuqina kwenethiwekhi, nokubonakala okugcwele kuzo zonke izingxenye eziyisisekelo—amaswishi, amasango, izintambo, kanye nesofthiwe yokuphatha—singakha ngempela ukuzivikela okuqinile kwamakhasimende ethu okungamelana nezinsongo zangaphandle ngenkathi siqinisekisa imisebenzi yokukhiqiza yangaphakathi ezinzile, ngaleyo ndlela kubenze bakwazi ukuhamba ngegagasi lokuguqulwa kwedijithali kancane kancane nangokuqhubekayo.
