Kev ruaj ntseg network feem ntau muaj peb ntu: Sab nraud ciam teb, sab hauv ciam teb, thiab cov khoom siv ruaj ntseg.
Sab Nraum Sab Nraud: Cov ciam teb sab nrauv yog txheej txheej tiv thaiv sab nraud ntawm kev ruaj ntseg network, feem ntau yog lub luag haujlwm tiv thaiv kev tawm tsam sab nraud. Nws feem ntau suav nrog ntau yam kev ruaj ntseg xws li firewalls, intrusion detection systems (IDS), thiab virtual private networks (VPNs).
Firewall: Lub foob pob hluav taws ua haujlwm ua "filter" ntawm cov neeg siv network thiab lwm cov tes hauj lwm, txheeb xyuas thiab thaiv kev tawm tsam los ntawm lwm cov tes hauj lwm los xyuas kom muaj kev ruaj ntseg ntawm cov neeg siv network.
**Intrusion Detection System (IDS):** An IDS monitors network traffic and logs in real time to promptly detect security vulnerabilities and malicious attacks, ensuring the security of the security network.
Virtual Private Network (VPN): Lub VPN siv cov txheej txheem cryptographic los tsim ib qhov av ntawm cov neeg siv network thiab pej xeem network, kom ntseeg tau qhov tsis pub lwm tus paub thiab kev nyab xeeb ntawm cov ntaub ntawv xa mus.
Internal ciam teb: Sab hauv ciam teb yog ib feem tseem ceeb ntawm kev ruaj ntseg network, feem ntau yog lub luag hauj lwm rau txwv kev nkag mus thiab tswj kev tso cai nyob rau hauv lub internal network. Nws feem ntau muaj ntau yam kev ruaj ntseg xws li routers, keyboards, thiab network cais cov khoom siv.
Router: Routers txwv thiab tswj kev nkag mus rau hauv lub network sab hauv, muab kev tswj xyuas ntau dua.
Cov Hloov Hloov: Cov keyboards ua cov kev kuaj xyuas kev ruaj ntseg thiab lim cov ntaub ntawv hauv cov ntaub ntawv hauv lub network sab hauv, kom ntseeg tau tias muaj kev nyab xeeb ntawm cov ntaub ntawv.
Network Isolation: Kev sib cais ntawm lub network faib cov kev sib txuas sab hauv rau hauv thaj chaw muaj kev ruaj ntseg sib txawv, txwv tsis pub nkag los ntawm lub network sab hauv mus rau lwm thaj chaw thiab ua kom muaj kev ruaj ntseg ntawm lub network sab hauv.
Cov cuab yeej siv kev ruaj ntseg: Cov cuab yeej ruaj ntseg yog cov cuab yeej siv ua lub luag haujlwm ruaj ntseg hauv kev ruaj ntseg network. Lawv feem ntau suav nrog cov tshuab kuaj pom kev nkag nkag (IDS), kev tiv thaiv kev nkag nkag (IPS), thiab cov khoom siv encryption.
Intrusion Detection Systems (IDS): IDS siv ntau yam thev naus laus zis los saib xyuas qhov tsis zoo ntawm kev nyab xeeb thiab kev tawm tsam tsis zoo hauv lub network hauv lub sijhawm tiag tiag, tshawb xyuas tam sim thiab ceeb toom kom muaj kev ruaj ntseg ntawm kev ruaj ntseg network.
Intrusion Prevention Systems (IPS): IPS saib xyuas lub network tsheb thiab cov txheej txheem hauv lub sijhawm tiag tiag, txheeb xyuas cov kev tawm tsam tsis zoo, thiab tiv thaiv lawv, ua kom muaj kev ntseeg siab ntawm kev ruaj ntseg network.
Encryption Devices: Cov khoom siv encryption encrypt cov ntaub ntawv rhiab, ua kom tsis pub lwm tus paub thiab kev nyab xeeb ntawm cov ntaub ntawv thaum kis.
