Thaum lub sijhawm ntawm Kev Lag Luam 4.0 thiab Kev Lag Luam Internet ntawm Yam (IIoT) kis mus thoob plaws ntiaj teb, kev sib koom ua ke ntawm Kev Siv Tshuab Ua Haujlwm (OT) thiab Kev Siv Tshuab Xov Xwm (IT) tsis tuaj yeem rov qab tau. Txawm hais tias qhov kev sib koom ua ke no coj kev tsim khoom thiab kev nkag siab txog cov ntaub ntawv tsis tau muaj dua, nws kuj rhuav tshem cov lus dab neeg ntawm "kev sib cais lub cev" ntawm Cov Txheej Txheem Tswj Kev Lag Luam (ICS) ib txwm muaj, ua rau cov tes hauj lwm tsim khoom tseem ceeb raug kev hem thawj cyber nyuaj zuj zus.
Ua ib tug thawj coj uas muaj hnub nyoog ib puas xyoo hauv kev xa cov teeb liab thiab kev daws teeb meem hauv network, Belden ntseeg tias qhov kev daws teeb meem tseem ceeb rau qhov teeb meem no tsis yog "patching" lub kaw lus tom qab nws tsim, tab sis rov qab mus rau qhov tseem ceeb - nkag mus tob rau hauv cov ntsiab cai kev ruaj ntseg txij li theem tsim kho vaj tse thawj zaug, tsim kom muaj kev tiv thaiv zoo nrog cov peev xwm kev ruaj ntseg.
Cov Kev Cov nyom tshwj xeeb ntawm OT Security: Vim li cas IT Security Strategies tsis tuaj yeem hloov kho ncaj qha?
Ua ntej peb tham txog cov kev daws teeb meem, peb yuav tsum paub meej tias qhov chaw ua haujlwm OT tshwj xeeb npaum li cas. Tsis zoo li cov chaw ua haujlwm IT uas muab qhov tseem ceeb rau cov ntaub ntawv "kev ceev ntiag tug," qhov tseem ceeb ntawm qhov chaw ua haujlwm OT yog qhov "muaj" thiab "kev txuas ntxiv mus." Txhua lub sijhawm tsis ua haujlwm uas tshwm sim los ntawm kev ntsuas kev ruaj ntseg tsis zoo tuaj yeem ua rau muaj kev poob nyiaj txiag lossis kev raug mob kev nyab xeeb ntau lab daus las.
Cov tes hauj lwm OT ntsib teeb meem tshwj xeeb:
Qhov muaj nyob yog qhov tseem ceeb tshaj plaws: Kev hloov kho tshiab lossis kev luam theej duab kev ruaj ntseg yuav tsum tsis txhob cuam tshuam cov txheej txheem tsim khoom.
Cov txheej txheem qub txeeg qub teg: Muaj ntau lub cuab yeej siv uas muaj hnub nyoog ntau xyoo (PLCs, HMIs) tsis txhawb nqa cov txheej txheem encryption niaj hnub no thiab tsis tuaj yeem kho tau.
Cov txheej txheem tshwj xeeb: Cov txheej txheem kev lag luam (xws li Modbus TCP, EtherCAT, EtherNet/IP, PROFINET) tsis tau tsim los nrog kev ruaj ntseg hauv siab thiab yooj yim rau kev tawm tsam.
Ib puag ncig hnyav: Cov khoom siv yuav tsum ua haujlwm ruaj khov hauv qhov kub thiab txias heev, av noo, thiab kev co.
Yog li ntawd, tsuas yog rov ua cov tswv yim kev ruaj ntseg IT hauv thaj chaw OT xwb tsis muaj txiaj ntsig. Cov kev daws teeb meem kev ruaj ntseg yuav tsum tau hloov kho kom haum rau cov kev xav tau tshwj xeeb ntawm OT.
Belden Hirschmann: Tsim Ib Lub Chaw Ruaj Ntseg Los Ntawm Peb
Txheej 1: Cov Cheeb Tsam & Cov Kav Dej - Kev Cais Tawm Network Ruaj Khob
Qhov no yog lub hauv paus tseem ceeb ntawm kev ruaj ntseg hauv network hauv kev lag luam. Los ntawm kev faib lub network ua ntau thaj chaw ruaj ntseg (Zones), xws li thaj chaw tswj, thaj chaw saib xyuas, thiab thaj chaw ua haujlwm ntau lawm, thiab txwv kev sib txuas lus ntawm thaj chaw mus rau cov kav dej uas tau teev meej, kev txav mus los ntawm sab nraud ntawm kev hem thawj tuaj yeem raug tswj tau zoo. Txawm tias thaj chaw raug cuam tshuam, qhov kev puas tsuaj tuaj yeem raug txwv kom tsawg kawg nkaus. Belden's Kev Xyaum: Belden'sHirschmanncov koob hloov pauv kev lag luam muab lub hauv paus kho vajtse ruaj khov thiab txhim khu kev qha rau kev tsim kom muaj tus qauv "cheeb tsam thiab cov kav dej" meej los ntawm kev faib tawm VLAN (Virtual Local Area Network), Cov Npe Tswj Kev Nkag Mus (ACLs), thiab kev tswj hwm chaw nres nkoj me me. Nws ua kom ntseeg tau tias tsuas yog cov tsheb khiav tau tso cai thiaj li tuaj yeem ntws ntawm thaj chaw ntawm ntau qib kev ruaj ntseg sib txawv.
Txheej 2: Kev Tiv Thaiv Ciam Teb - Cov Neeg Saib Xyuas Lub Rooj Vag Qib Kev Lag Luam Ntse
Tom qab faib lub network ua thaj chaw, ciam teb ntawm txhua thaj chaw xav tau ib tug "gatekeeper" muaj zog los ua qhov kev kuaj xyuas kev ruaj ntseg nruj. Qhov no tsis yog tsuas yog kev thaiv tsheb yooj yim xwb, tab sis xav tau kev tiv thaiv ntse uas nkag siab cov lus hauv kev lag luam. Belden's Practice: Cov Eagle series industrial security firewalls yog lub hauv paus ntawm txheej no. Nws tsis yog tsuas yog firewall xwb; nws yog ib tug kws tshaj lij Deep Packet Inspection (DPI) uas tsim tshwj xeeb rau OT ib puag ncig. Nws tuaj yeem "nkag siab" cov txheej txheem kev lag luam xws li Modbus TCP, EtherNet/IP, thiab OPC, tso cai rau tsuas yog cov lus txib raug cai uas ua raws li cov cai ua ntej, thaum tsis lees txais cov lus txib tsis zoo lossis phem, muab kev tiv thaiv rau PLCs uas tsis muaj zog uas tsis tuaj yeem kho tau.
Txheej thib peb: Kev Ruaj Ntseg thiab Kev Pom Kev ntawm Network–
Kev Ua Haujlwm Txuas Ntxiv Mus Thiab Teb Sai Sai Lub hauv paus ntawm kev ruaj ntseg yog kev ruaj khov. Lub network uas feem ntau poob qis thiab ua haujlwm tsis zoo yog qhov kev pheej hmoo loj tshaj plaws ntawm kev ruaj ntseg. Ntxiv mus, koj tsis tuaj yeem tiv thaiv qhov koj pom tsis tau. Kev nkag siab meej txog tag nrho lub network yog qhov yuav tsum tau ua ua ntej rau kev tiv thaiv ua ntej thiab teb sai sai.
Belden Cov Kev Xyaum: Kev Ruaj Kho Vajtse: Belden cov cables, connectors, thiab industrial switches yog tsim los rau cov chaw ua haujlwm hnyav, muaj kev tiv thaiv zoo heev rau kev cuam tshuam electromagnetic, ntau qhov kub thiab txias, thiab kev ntseeg siab, ua kom muaj kev sib txuas network ntawm lub cev.
Kev Pom Kev Hauv Network:HirschmannLub software tswj hwm network HiVision Industrial tuaj yeem nrhiav tau txhua yam khoom siv hauv network, muab kev pom tseeb ntawm lub network topology thiab kev noj qab haus huv. Lub kaw lus yuav tshaj tawm ceeb toom tam sim ntawd thaum nkag mus rau hauv cov khoom siv tsis raug cai lossis qhov txuas tsis ua haujlwm, tso cai rau cov thawj coj network nkag siab txog qhov xwm txheej thiab teb sai sai.
Kev ruaj ntseg yog tsim los rau hauv, tsis yog ntxiv rau. Kev ruaj ntseg hauv network hauv kev lag luam yog kev sib ntaus sib tua mus sij hawm ntev; tsis muaj ib qho yooj yim ua tau. Txawm li cas los xij, lub network uas muaj kev tsim qauv kev ruaj ntseg siv rau ntawm theem kev tsim kho vaj tse yuav muaj kev tiv thaiv ntau dua rau kev pheej hmoo dua li cov kab ke uas vam khom cov software kev ruaj ntseg ntxiv.
Belden lub zeem muag yog qhov tseeb thiab tsis hloov pauv: kev ruaj ntseg yuav tsum tsis yog qhov xav tom qab kim heev, tab sis yog qhov tseem ceeb ntawm lub network. Los ntawm kev koom ua ke cov ntsiab cai xws li kev cais thaj chaw, kev tiv thaiv puag ncig, kev ruaj khov ntawm lub network, thiab kev pom tag nrho rau hauv txhua qhov tseem ceeb - cov hloov pauv, rooj vag, cov cables, thiab software tswj - peb tuaj yeem tsim kev tiv thaiv zoo rau peb cov neeg siv khoom uas tuaj yeem tiv taus kev hem thawj sab nraud thaum ua kom muaj kev ua haujlwm ruaj khov sab hauv, yog li ua rau lawv taug kev ntawm nthwv dej ntawm kev hloov pauv digital ruaj khov thiab ruaj khov.
