Txhua tus neeg hauv lub neej ntau dua lossis tsis muaj kev sib cuag nrog nws thiab OT pronoun, peb yuav tsum tau paub dua, yog li niaj hnub no qhia rau koj ib co ntawm cov ntsiab lus tseem ceeb ntawm nws thiab OT.
Dab tsi yog cov thev naus laus zis thev naus laus zis (OT)?
Kev Siv Tshuab Ua Haujlwm (OT) yog kev siv cov khoom siv kho vajtse thiab software los soj ntsuam thiab tswj cov txheej txheem lub cev, khoom siv, thiab cov vaj tse lub cev. Cov thev naus laus zis thev naus laus zis muaj nyob thoob plaws cov cuab tam loj ntawm cov cuab yeej-intensive cov haujlwm. Lawv tau ua ntau yam haujlwm uas muaj ntau yam kev ua haujlwm los ntawm kev saib xyuas cov khoom tseem ceeb (ci) los tswj cov neeg hlau hauv av.
OT siv ntau yam kev lag luam suav nrog kev tsim khoom, roj thiab roj thiab hluav taws xob thiab faib, avitime, kev tsheb nqaj hlau, thiab khoom siv.
Nws (cov ntaub ntawv thev naus laus zis) thiab ot (ua haujlwm thev naus laus zis) yog ob qho kev sawv cev thev naus laus zis, thiab muaj qee yam sib txawv thiab sib txuas ntawm lawv.
Nws (cov thev naus laus zis thev naus laus zis) yog hais txog cov cuab yeej thev naus laus zis cuam tshuam nrog cov khoom siv computer, software thiab cov ntaub ntawv tswj hwm, uas yog tswj cov txheej txheem-theem thiab cov txheej txheem kev lag luam. Nws tsuas yog tsom rau cov ntaub ntawv kev ua, kev sib txuas lus hauv network, xws li cov chaw ua haujlwm hauv chaw lag luam, xws li cov cuab yeej tswj hwm sab hauv, khoom siv network, thiab lwm yam.
Kev Siv Tshuab Ua Haujlwm (OT) yog hais txog cov thev naus laus zis ntsig txog kev ua haujlwm ntawm lub cev ua haujlwm tiag tiag, uas yog tswj cov cuab yeej yooj yim, thiab cov txheej txheem kev ruaj ntseg. OT tsom rau kev sib tham ntawm kev tswj siv tshuab, kev saib xyuas cov ntaub ntawv tiag tiag thiab ua haujlwm ntawm cov tshuab tswj khoom lag luam (Scada), sensors thiab kev sib txuas lus thiab kev sib txuas lus thiab kev sib txuas lus.
Kev sib txuas ntawm nws thiab ot yog tias cov thev naus laus zis thiab kev pabcuam ntawm nws tuaj yeem muab kev txhawb nqa thiab kev ua kom zoo dua rau cov chaw taws teeb saib xyuas; Nyob rau tib lub sijhawm, cov ntaub ntawv tiag tiag thiab ntau lawm cov txheej txheem ntawm OT kuj tseem tuaj yeem muab cov ntaub ntawv tseem ceeb rau nws cov ntaub ntawv kev ua lag luam thiab cov ntaub ntawv tshuaj xyuas.
Kev sib koom ua ke ntawm nws thiab OT tseem yog ib txoj kev tseem ceeb nyob rau hauv cov chaw muaj kev lag luam tam sim no. Los ntawm kev sib xyaw ua ke thev naus laus zis thiab cov ntaub ntawv ntawm nws thiab ot, muaj txiaj ntsig ntau dua thiab kev tswj hwm kev ua haujlwm tuaj yeem ua tiav. Qhov no ua rau muaj cov khoom lag luam thiab cov lag luam kom zoo dua teb rau kev ua lag luam hloov pauv, txhim kho ntau dua thiab zoo thiab txo cov nqi thiab kev pheej hmoo.

OT kev ruaj ntseg yog dab tsi?
OT kev ruaj ntseg yog txhais raws li cov kev coj ua thiab thev naus laus zis uas tau siv rau:
(a) Tiv thaiv cov neeg, cov cuab tam, thiab cov ntaub ntawv,
(b) saib xyuas thiab / tswj cov cuab yeej siv lub cev, cov txheej txheem thiab cov xwm txheej, thiab
(c) Pib npaj lub xeev cov kev hloov pauv mus rau enterprise ot systems.
OT kev ruaj ntseg kev daws teeb meem suav nrog cov kev ruaj ntseg thev naus laus zis ntawm cov ntaub ntawv firewall (Ngfws) rau cov ntaub ntawv kev nyab xeeb thiab kev tswj hwm (Siem) rau kev nkag mus thiab kev tswj hwm, thiab ntau ntxiv.
Kev lig kev cai, OT cyber kev ruaj ntseg tsis tsim nyog vim tias cov tshuab ot tsis txuas nrog Is Taws Nem. Xws li, lawv tsis tau raug rau sab nraud hawv. Raws li cov kev txhim kho digital (DI) kev nthuav dav thiab nws cov networks hloov pauv, cov koomhaum tended Bolt-ntawm tshwj xeeb cov kev daws teeb meem.
Cov hau kev no rau OT kev ruaj ntseg ua rau muaj lub network uas daws teeb meem tsis tuaj yeem faib cov ntaub ntawv thiab muab kev pom puv nkaus.
Feem ntau, nws thiab ot networks khaws cia cais uas ua rau luam tawm cov kev ruaj ntseg thiab eschewing transparency. Cov no nws network tsis tuaj yeem taug qab dab tsi tshwm sim thoob plaws ntawm kev tawm tsam.

Feem ntau, OT networks cov ntawv tshaj tawm rau lub ROo thiab nws network qhia rau COO, uas ua rau ob pawg neeg muaj kev nyab xeeb txhua lub network ntawm tag nrho cov network. Qhov no tuaj yeem ua rau nws nyuaj los txheeb cov ciaj ciam ntawm cov pab pawg nres vim tias cov neeg khib nyiab no tsis paub dab tsi nrog lawv tus kheej lub network. Ntxiv rau qhov nyuaj rau kev tswj tau zoo, OT nws tes hauj lwm tawm qee qhov loj loj hauv kev ruaj ntseg.
Raws li piav qhia nws txoj kev mus rau OT kev ruaj ntseg, nws yog los xyuas kev hem thawj thaum ntxov siv kev paub tag nrho ntawm nws thiab kev sib koom tes OT.
Nws (cov ntaub ntawv thev naus laus zis) thiab cov thev naus laus zis (kev ua haujlwm thev naus laus zis)
Zaj piav
Nws (cov ntaub ntawv thev naus laus zis): Hais txog kev siv cov khoos phis tawj, tes hauj lwm, thiab software los tswj cov ntaub ntawv thiab cov ntaub ntawv hauv kev ua lag luam thiab cov kev koom ua ke. Nws suav nrog txhua yam los ntawm kho vajtse (cov servers, routers) rau software (ntawv thov, databases) uas txhawb kev ua lag luam kev lag luam, kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus, thiab kev sib txuas lus.
Ot (ua haujlwm thev naus laus zis): Koom tes kho vajtse thiab software uas pom lossis ua kom hloov pauv ntawm kev saib xyuas lub cev thiab tswj cov txheej txheem ntawm lub cev, thiab cov xwm txheej hauv ib lub koom haum. OT feem ntau pom hauv kev tsim khoom, xws li kev tsim khoom, lub zog, thiab suav nrog Scada (kev saib xyuas kev tswj hwm thiab cov ntaub ntawv tau txais) thiab plcs (programricable logic controllers).

Kev sib tos
Nrog rau kev nce ntawm kev lag luam 4.0 thiab internet ntawm yam (iot), lub convergence ntawm nws thiab OT yog ua qhov tseem ceeb. Qhov kev sib koom ua ke no los txhim kho kev ua tau zoo, txhim kho cov ntaub ntawv tshuaj xyuas, thiab pab tau zoo dua kev txiav txim siab. Txawm li cas los xij, nws tseem qhia txog cov nyom uas muaj feem rau CyberseCurity, raws li cov tshuab ot tau raug cais los ntawm nws cov tes hauj lwm raug cais.
