Kev Ruaj Ntseg Kev Ua Haujlwm Zoo Tshaj Plaws rau Siemens thiab 200sp hauv Kev Lag Luam Tes Haujlwm

Yog tias koj ua haujlwm nrog kev lag luam Automation, koj tau ntsib cov siemens simatic li 200sp. Nws yog cov faib tawm nrov I / O uas siv rau hauv ntau lub chaw ua haujlwm thiab cov txheej txheem ib puag ncig vim nws qhov loj me, nruab tau yooj yim, thiab hloov tau yooj yim.

Txawm li cas los xij, nrog kev yooj yim ntawm cov khoom siv sib txuas los ntawm kev pheej hmoo ntawm kev hem thawj cyber. Ransomware, kev tso cai tsis tau tso cai, thiab kev tawm tsam tsis tau muaj teeb meem tsis yog teeb meem rau nws ntxiv - lawv muaj teeb meem loj hauv kev muaj teeb meem, ib yam nkaus. Cov cuab yeej tsis muaj kev tsis txaus siab xws li ET 200Sp tuaj yeem yooj yim dhau cov ntsiab lus nkag rau cov neeg tawm tsam, muab koj txoj haujlwm tag nrho ntawm kev pheej hmoo.

Yog vim li cas thiaj li ua tiav koj cov khoom siv lag luam siv, suav nrog Siemens simatic li 200SP, yog qhov tseem ceeb; Peb nyob ntawm no los taug koj los ntawm kev ua li cas kom raug.

1. Nkag siab qhov kev hem thawj rau koj cov kev lag luam network

Ua ntej dhia mus rau hauv kev daws teeb meem, cia peb xav txog qhov uas peb tau tawm tsam. Kev tswj hwm cov tshuab (ics) feem ntau yog cov hom phiaj hauv txoj kev uas nws siv.

Qee qhov kev hem tshaj plaws muaj xws li:

● Tsis muaj cai nkag: Hackers lossis cov neeg nyob sab hauv tau nkag mus rau koj cov khoom siv uas tsis tau tso cai.

● Malware & Ransomware: Cov software tsim hluav taws xob tsis zoo tuaj yeem kaw hauv lossis lub tshuab tswj kev tsis sib haum xeeb.

● Tus txiv neej-hauv-nruab nrab tawm tsam: Qhov twg ib tug neeg zais ntshis cuam tshuam los sib txuas lus rau cov ntaub ntawv nyiag lossis txhaj cov lus txib.

● Tsis kam-ntawm-kev pabcuam (DOS) tawm tsam: Hla koj lub kaw lus nrog cov tsheb khiav, ua rau kom qeeb lossis ua tiav cov khoom noj.

Yog tsis muaj kev tiv thaiv tsim nyog, koj siemens thiab 200sp yog qhov yooj yim rau tag nrho cov no. Tias yog vim li cas kev ruaj ntseg yuav tsum yog ib feem ntawm kev teeb tsa - tsis yog tom qab.

2. SIEMENS ET 200SP kev ruaj ntseg kev coj ua zoo tshaj plaws

A. Kev teeb tsa kev ruaj ntseg network

Ib qho ntawm thawj yam uas koj tuaj yeem ua tau yog khaws koj lub tshuab sib cais los ntawm koj lub lag luam lag luam. Siv cov vlan ntu kom cais tawm cov et

Nruab chaw firewalls rau lim tsheb kauj vab mus rau hauv thiab tawm ntawm lub et 50sp. Tsuas yog cia ua dab tsi tsim nyog. Kaw cov kev pabcuam lossis cov chaw nres nkoj koj tsis siv, zoo li http lossis SNMP, uas tuaj yeem pheej hmoo yog tias qhib sab laug.

B. Kev Nkag Mus Rau Kev Tswj Xyuas & Kev Txheeb Xyuas

Lub ntsiab lus tsis txaus ntseeg ntawm cov txheej txheem tseem siv lub neej tsis muaj npe. Ntawd yog qhov kev pheej hmoo loj. Hloov txhua tus password txhua lub sijhawm rau ntawm ET 200SP thiab nws cov tswj hwm ntsig txog cov neeg tswj hwm.

Nyob rau hauv TIA portal, koj tuaj yeem teeb tsa txoj kev tswj hwm lub luag haujlwm (RBAC) yog li cov neeg siv tsuas yog nkag mus rau cov yam uas xav tau. Yog tias koj tus qauv ntawm et 200sp txhawb nws, pab kom khau khau thiab firmware ncaj ncees. Cov no ua kom cov txheej txheem tsis tau ua tampered nrog thaum nws lub zog ntawm.

C. Tsis tu ncua Firmware & Patch Kev Tswj Xyuas

Hackers feem ntau coj kom zoo dua ntawm software outdated. Tias yog vim li cas thiaj khaws koj cov firmware tam sim no tseem ceeb heev.

Ua nws tus cwj pwm los nruab cov firmware tshiab tshiab los ntawm Siemens. Koj tseem tuaj yeem sau npe yuav ua rau Siemens kev ruaj ntseg kev ua si lossis ntawv ceeb toom, yog li koj tau ceeb toom sai li sai tau qhov tsis pom tseeb.

Teem lub sijhawm tu ib txwm mus siv thaj ua kom thaj ua kom thaj ua rau thaj chaw tos rau lub lis piam.

D. Kev sib txuas lus ruaj ntseg (encryption & vpns)

Thaum twg koj txuas rau koj li 200Sp los ntawm chaw nres tsheb txua lossis lwm lub cuab yeej siv, siv cov qauv sib txuas lus ntxiv xws li TLS / SSL.

Yog tias koj xav tau cov chaw taws teeb nkag, ib txwm mus rau lub VPN-tsis tau nthuav tawm ncaj qha rau hauv Is Taws Nem. Koj tuaj yeem siv Siemens Scalance routers lossis ib qho chaw vpn sab nraud rau qhov no. Thiab nco ntsoov ua kom tsis muaj kev txiav txim siab tsis tau zoo li telnet thiab FTP, uas yog Outdated thiab tsis nyab xeeb.

E. Lub Cev Kev Ruaj Ntseg thiab Kev Saib Xyuas

Txawm tias tus neegT Dero SaBellAm kev ruaj ntseg yuav tsis pab yog tias ib tus neeg tuaj yeem taug kev hauv thiab tshem koj lub cuab yeej.

Nco ntsoov tias cov qauv et200Sp yog nyob rau hauv chav xauv lossis tswj chav thiab tsuas yog siv tau rau cov neeg ua haujlwm raug cai. Ntawm lub network sab, cov cuab yeej zoo li Siem Systems lossis Anomaly Nrhiav tau software yuav tsum tau siv los saib xyuas txhua tus cwj pwm coj txawv txawv.

Teev txhua yam - los ntawm kev nkag mus rau kev hloov pauv hloov - yog li koj ib txwm muaj cov ntaub ntawv tseeb ntawm qhov tshwm sim.

3. Ntxiv kev ruaj ntseg nta ntawm siemens

Siemens muaj ntau cov cuab yeej uas ua rau kev tswj hwm kev ruaj ntseg yooj yim dua.

● Sinec NMS yog lawv lub chaw tswj hwm kev tswj hwm network uas pab saib xyuas thiab tswj cov cuab yeej kev nyab xeeb thoob koj lub network.

● Nyob rau hauv TIA portal, koj tuaj yeem siv cov yam ntxwv xws li kev ua haujlwm ntawm Project

● Siemens kuj tseem txhawb txoj kev tiv thaiv kev tiv thaiv-hauv-qhov tob, uas txhais tau tias siv cov khaubncaws sab nraud povtseg ntawm txhua qib mus rau qhov chaw ntawm lub cev.

Yog tias koj ua raws cov cuab yeej built-intilt-intilt-intilt thiab ua rau lawv ib feem ntawm koj cov haujlwm ua haujlwm, koj li kev teeb tsa yuav muaj kev nyab xeeb dua.

4. Cov kev ua txhaum uas tau ua txhaum rau

Txawm hais tias nrog kev mob siab zoo, qee qhov yuam kev tuaj yeem qhib lub qhov rooj mus tawm tsam. Zam kev ua yuam kev no:

● Khaws cov ntawv pov thawj: Hloov lawv tam sim ntawd tom qab teeb.

● Tiaj Tes Networks: Yog tias txhua yam ntawm ib lub network, ua txhaum cai nyob rau hauv ib thaj chaw tuaj yeem kis txhua qhov chaw. Ib txwm siv network segmentation.

● Tsis muaj kev ntsuas kev ruaj ntseg ib txwm muaj: Tsis muaj kev kuaj xyuas lossis kev xeem nkag mus, koj yuav tsis paub koj qhov tsis muaj zog txog thaum nws lig dhau lawm.

Los ntawm kev paub txog thiab hais cov no thaum ntxov, koj zam zam cov teeb meem loj dua tom qab.
