Sebakeng sa kajeno sa indasteri se hokahaneng, tlhoko ea mehato e matla ea cybersecurity ha e so ka e ba kholo ho feta. Ha mahlale a dijithale a ntse a tsoela pele ho kenella lits'ebetsong tsa indasteri, kotsi ea litšokelo le litlhaselo tsa cyber e eketseha haholo. Ka hona, ho netefatsa ts'ireletso ea marang-rang a indasteri e fetohile ntho e tlang pele ho mekhatlo ho pholletsa le liindasteri. Karolo ea bohlokoa ea ho boloka marang-rang a indasteri ke ts'ebeliso ea li-switch tsa Ethernet tsa indasteri, tse bapalang karolo ea bohlokoa ho ntlafatseng ts'ireletso ea marang-rang.
Li-switch tsa Industrial Ethernet ke lisebelisoa tse khethehileng tsa marang-rang tse etselitsoeng ho tsamaisa puisano le ho fetisetsa data libakeng tsa indasteri. Ho fapana le li-switch tsa Ethernet tsa setso, li-switch tsa Ethernet tsa indasteri li etselitsoe ho mamella maemo a thata a tloaelehileng libakeng tsa indasteri, joalo ka mocheso o feteletseng, mongobo le tšitiso ea motlakase. Li-switch tsena li theha mokokotlo oa marang-rang a liindasteri, li fana ka data ka mokhoa o se nang moeli le ka ts'epo lipakeng tsa lisebelisoa tse hokahantsoeng joalo ka li-programmable logic controllers (PLCs), li-interfaces tsa mochini oa batho (HMIs) le lisebelisoa tse ling tsa bohlokoa tsa indasteri.
Ha ho tluoa ho cybersecurity, li-switch tsa Ethernet tsa indasteri ke mokhoa oa bohlokoa oa ts'ireletso khahlano le lits'oso le bofokoli bo ka bang teng. Li-switch tsena li na le likarolo tsa ts'ireletso tse tsoetseng pele tse thusang ho fokotsa kotsi ea phihlello e sa lumelloeng, tlolo ea molao ea data le litlhaselo tse ling tsa marang-rang. E 'ngoe ea likarolo tsa bohlokoa tsa ts'ireletso tse fanoang ke li-switch tsa Ethernet tsa indasteri ke taolo ea phihlello e thehiloeng ho port, e lumellang batsamaisi ba marang-rang ho thibela phihlello ea likou tse itseng tsa marang-rang ho latela mekhoa e boletsoeng esale pele. Sena se thusa ho thibela lisebelisoa tse sa lumelloeng ho fihlella marang-rang a indasteri, ho fokotsa menyetla ea ho tlola ts'ireletso.
Holim'a moo,li-switches tsa Ethernet tsa indasterits'ehetsa theknoloji ea LAN (VLAN), e ka arolang marang-rang ho li-subnet tse ngata tse arohaneng. Ka ho theha li-VLAN tse arohaneng bakeng sa lisebelisoa le litsamaiso tse fapaneng tsa indasteri, mekhatlo e ka ba le litšokelo tse ka bang teng tsa ts'ireletso le ho fokotsa phello ea litlolo tsa ts'ireletso. Karolo ena e boetse e thusa ho laola sephethephethe sa marang-rang le ho thibela lisebelisoa tse sa lumelloeng ho thibela data ea bohlokoa.
Ntle le taolo ea phihlello le karohano ea marang-rang, li-switch tsa Ethernet tsa indasteri li fana ka matla a matla a encryption ho netefatsa polokeho ea phetiso ea data ea marang-rang. Ka ho tšehetsa liprothokholo tse kang Secure Sockets Layer (SSL) le Transport Layer Security (TLS), li-switch tsa Ethernet tsa indasteri li netefatsa hore data e fapanyetsanoang lipakeng tsa lisebelisoa tse hokahaneng e ngotsoe ka mokhoa o patiloeng, e leng ho nolofalletsang bahlaseli ba marang-rang ho fumana le ho manolla tlhahisoleseling. phephetso.
Ho feta moo, li-switch tsa Ethernet tsa indasteri li etselitsoe ho fana ka leihlo la nako ea sebele le ponahalo ea sephethephethe sa marang-rang, ho lumella batsamaisi ho lemoha le ho arabela liketsahalong tse ka 'nang tsa e-ba teng tsa tšireletso. Ka ho sebelisa likarolo tse kang port mirroring le ho beha leihlo sephethephethe, mekhatlo e ka fumana leseli mabapi le ts'ebetso ea marang-rang le ho tseba boitšoaro bofe kapa bofe bo sa tloaelehang kapa bo belaetsang bo ka bonts'ang ts'okelo ea ts'ireletso.
Ha marang-rang a indasteri a ntse a tsoela pele ho hola le ho hola, karolo ea li-switch tsa Ethernet tsa indasteri ho ts'ireletso ea marang-rang e tla ba ea bohlokoa le ho feta. Ha theknoloji ea ts'ebetso (OT) le lits'ebetso tsa theknoloji ea tlhahisoleseling (IT) li kopana, tlhoko ea litharollo tse kopaneng tsa cybersecurity tse akaretsang libaka tseo ka bobeli e ba tsa bohlokoa. Li-switch tsa Industrial Ethernet li loketse hantle ho sebetsana le liphephetso tse ikhethang tsa cybersecurity tse tobaneng le libaka tsa indasteri ka likarolo tsa tsona tsa ts'ireletso le moralo o thata.
Ha re phethela,Li-switch tsa Ethernet tsa indasteribapala karolo ea bohlokoa ho sireletseng marang-rang a indasteri ho tsoa litšokelong tsa cyber. Li-switch tsa Industrial Ethernet li thusa mekhatlo ho matlafatsa ts'ireletso ea bona le ho sireletsa thepa ea bohlokoa ea indasteri ka ho kenya ts'ebetsong mehato e matla ea ts'ireletso e kang taolo ea phihlello, karohano ea marang-rang, encryption, le tlhahlobo ea nako ea nnete. Ha marang-rang a indasteri a ntse a tsoela pele ho hokahanngoa le ho hokahana, ho amoheloa ha li-switch tsa Ethernet tsa indasteri ho bohlokoa bakeng sa ho aha meaho ea liindasteri e tsitsitseng le e sireletsehileng.
