Hauv kev ruaj ntseg ntawm lub network, Intrusion Detection System (IDS) thiab Intrusion Prevention System (IPS) ua lub luag haujlwm tseem ceeb. Tsab xov xwm no yuav tshawb nrhiav tob txog lawv cov lus txhais, lub luag haujlwm, qhov sib txawv, thiab cov xwm txheej ntawm kev siv.
IDS (Intrusion Detection System) yog dab tsi?
Kev txhais ntawm IDS
Lub Tshuab Tshawb Nrhiav Kev Nkag Mus yog ib lub cuab yeej ruaj ntseg uas saib xyuas thiab tshuaj xyuas cov tsheb khiav hauv network kom paub txog cov haujlwm phem lossis kev tawm tsam. Nws tshawb nrhiav cov cim uas phim cov qauv tawm tsam paub los ntawm kev tshuaj xyuas cov tsheb khiav hauv network, cov ntaub ntawv teev cia ntawm lub system, thiab lwm yam ntaub ntawv tseem ceeb.
IDS ua haujlwm li cas
IDS ua haujlwm feem ntau hauv cov hauv qab no:
Kev Tshawb Pom Kos NpeIDS siv cov cim qhia ua ntej ntawm cov qauv tawm tsam rau kev sib phim, zoo ib yam li cov tshuab ntsuas kab mob rau kev ntes cov kab mob. IDS tsa ib qho kev ceeb toom thaum tsheb khiav muaj cov yam ntxwv uas phim cov cim no.
Kev Tshawb Pom Qhov Txawv Txawv: IDS saib xyuas qhov pib ntawm kev ua haujlwm hauv network thiab tsa cov lus ceeb toom thaum nws pom cov qauv uas txawv ntawm tus cwj pwm ib txwm muaj. Qhov no pab txheeb xyuas cov kev tawm tsam tsis paub lossis tshiab.
Kev Tshawb Fawb Txog Cov Txheej TxheemIDS tshuaj xyuas kev siv cov txheej txheem network thiab ntes tus cwj pwm uas tsis ua raws li cov txheej txheem txheem, yog li txheeb xyuas qhov kev tawm tsam uas yuav tshwm sim.
Hom ntawm IDS
Nyob ntawm seb lawv tau xa mus rau qhov twg, IDS tuaj yeem muab faib ua ob hom tseem ceeb:
Cov ID ntawm Network (NIDS): Muab tso rau hauv lub network los saib xyuas txhua qhov kev khiav tsheb hla lub network. Nws tuaj yeem ntes tau ob qho tib si network thiab transport layer attacks.
Cov ID ntawm tus tswv tsev (HIDS): Muab tso rau ntawm ib lub host xwb los saib xyuas cov haujlwm ntawm lub system ntawm lub host ntawd. Nws tsom mus rau kev nrhiav cov kev tawm tsam ntawm tus host xws li malware thiab tus cwj pwm tsis zoo ntawm tus neeg siv.
IPS (Intrusion Prevention System) yog dab tsi?
Kev txhais ntawm IPS
Cov Txheej Txheem Tiv Thaiv Kev Nkag Mus yog cov cuab yeej ruaj ntseg uas siv cov kev ntsuas ua ntej los nres lossis tiv thaiv cov kev tawm tsam tom qab pom lawv. Piv nrog IDS, IPS tsis yog tsuas yog ib lub cuab yeej rau kev saib xyuas thiab ceeb toom xwb, tab sis kuj yog ib lub cuab yeej uas tuaj yeem cuam tshuam thiab tiv thaiv cov kev hem thawj.
IPS ua haujlwm li cas
IPS tiv thaiv lub kaw lus los ntawm kev thaiv cov tsheb khiav phem uas ntws los ntawm lub network. Nws txoj cai ua haujlwm tseem ceeb suav nrog:
Thaiv Kev Tawm Tsam TshebThaum IPS pom cov tsheb khiav tawm tsam, nws tuaj yeem ua cov kev ntsuas tam sim ntawd los tiv thaiv cov tsheb khiav no kom tsis txhob nkag mus rau hauv lub network. Qhov no pab tiv thaiv kev tawm tsam ntxiv.
Rov pib dua qhov kev sib txuas lus: IPS tuaj yeem pib dua qhov kev sib txuas uas cuam tshuam nrog kev tawm tsam, yuam tus neeg tawm tsam rov tsim kev sib txuas thiab yog li cuam tshuam qhov kev tawm tsam.
Kev Hloov Kho Cov Cai FirewallIPS tuaj yeem hloov kho cov cai ntawm firewall kom thaiv lossis tso cai rau cov hom tsheb khiav tshwj xeeb kom hloov kho rau cov xwm txheej kev hem thawj tiag tiag.
Hom ntawm IPS
Ib yam li IDS, IPS muaj ob hom loj:
Network IPS (NIPS): Muab tso rau hauv lub network los saib xyuas thiab tiv thaiv kev tawm tsam thoob plaws hauv lub network. Nws tuaj yeem tiv thaiv kev tawm tsam ntawm txheej network thiab txheej thauj mus los.
Tus tswv tsev IPS (HIPS): Muab tso rau ntawm ib lub host kom muab kev tiv thaiv zoo dua, feem ntau yog siv los tiv thaiv kev tawm tsam ntawm tus host xws li malware thiab exploit.
Qhov txawv ntawm Intrusion Detection System (IDS) thiab Intrusion Prevention System (IPS) yog dab tsi?
Txoj Kev Ua Haujlwm Sib Txawv
IDS yog ib lub tshuab saib xyuas tsis siv neeg, feem ntau yog siv rau kev ntes thiab ceeb toom. Qhov sib txawv, IPS yog ua ntej thiab muaj peev xwm ua cov kauj ruam los tiv thaiv kev tawm tsam.
Kev Sib Piv Txog Kev Pheej Hmoo thiab Cov Txiaj Ntsig
Vim yog qhov xwm txheej ntawm IDS uas tsis ua haujlwm, nws yuav tsis pom lossis tsis muaj tseeb, thaum kev tiv thaiv IPS uas ua haujlwm yuav ua rau muaj kev tua phom. Yuav tsum tau sib npaug ntawm kev pheej hmoo thiab kev ua haujlwm zoo thaum siv ob lub tshuab.
Kev Sib Txawv ntawm Kev Xa Mus thiab Kev Teeb Tsa
Feem ntau IDS muaj kev ywj pheej thiab tuaj yeem xa mus rau ntau qhov chaw sib txawv hauv lub network. Qhov sib txawv, kev xa tawm thiab kev teeb tsa ntawm IPS xav tau kev npaj ua tib zoo kom tsis txhob cuam tshuam nrog cov tsheb khiav ib txwm muaj.
Kev Siv Ua Ke ntawm IDS thiab IPS
IDS thiab IPS sib pab ua ke, nrog rau kev saib xyuas thiab muab cov lus ceeb toom rau IDS thiab IPS ua cov kev tiv thaiv ua ntej thaum tsim nyog. Kev sib koom ua ke ntawm lawv tuaj yeem tsim kom muaj kab tiv thaiv kev ruaj ntseg hauv network zoo dua.
Nws yog ib qho tseem ceeb uas yuav tsum tau hloov kho cov cai, cov kos npe, thiab kev txawj ntse txog kev hem thawj ntawm IDS thiab IPS tsis tu ncua. Kev hem thawj hauv cyber yeej hloov pauv tas li, thiab kev hloov kho raws sijhawm tuaj yeem txhim kho lub peev xwm ntawm lub system los txheeb xyuas cov kev hem thawj tshiab.
Nws yog ib qho tseem ceeb heev uas yuav tsum kho cov cai ntawm IDS thiab IPS kom haum rau qhov chaw sib txuas lus thiab cov kev xav tau ntawm lub koom haum. Los ntawm kev kho cov cai, qhov tseeb ntawm lub kaw lus tuaj yeem txhim kho thiab cov lus tsis tseeb thiab kev raug mob ntawm tus phooj ywg tuaj yeem txo qis.
IDS thiab IPS yuav tsum muaj peev xwm teb tau rau tej kev hem thawj uas yuav muaj tau tiag tiag. Kev teb sai thiab raug yuav pab tiv thaiv cov neeg tawm tsam kom tsis txhob ua rau muaj kev puas tsuaj ntxiv rau hauv lub network.
Kev saib xyuas tas mus li ntawm cov tsheb khiav hauv network thiab kev nkag siab txog cov qauv tsheb khiav ib txwm muaj peev xwm pab txhim kho lub peev xwm nrhiav pom qhov tsis zoo ntawm IDS thiab txo qhov ua tau ntawm cov cuav zoo.
