Hauv thaj tsam ntawm kev ruaj ntseg network, kev nkag mus nrhiav qhov system (IDS) thiab kev tiv thaiv kev nkag mus (IPS) ua lub luag haujlwm tseem ceeb. Kab lus no yuav tshawb nrhiav tob txog lawv cov ntsiab lus, lub luag haujlwm, qhov sib txawv, thiab kev siv cov xwm txheej.
IDS (Intrusion Detection System) yog dab tsi?
Kev txhais ntawm IDS
Intrusion detection system yog ib qho cuab yeej ruaj ntseg uas saib xyuas thiab txheeb xyuas cov tsheb khiav hauv lub network txhawm rau txheeb xyuas cov haujlwm phem lossis kev tawm tsam. Nws tshawb nrhiav kos npe uas phim cov qauv kev tawm tsam uas paub los ntawm kev tshuaj xyuas cov tsheb khiav hauv lub network, cov ntaub ntawv kaw lus, thiab lwm yam ntaub ntawv ntsig txog.
IDS ua haujlwm li cas
IDS ua haujlwm feem ntau hauv cov hauv qab no:
Kev Tshawb Nrhiav Kos Npe: IDS siv lub npe kos npe ua ntej ntawm cov qauv kev tawm tsam rau kev sib txuam, zoo ib yam li tus kab mob scanners txhawm rau txheeb xyuas cov kab mob. IDS tsa ib qho kev ceeb toom thaum lub tsheb muaj cov yam ntxwv uas phim cov npe no.
Kev kuaj pom tsis meej: IDS saib xyuas lub hauv paus ntawm kev ua haujlwm hauv network ib txwm muaj thiab nce kev ceeb toom thaum nws pom cov qauv uas txawv ntawm tus cwj pwm ib txwm muaj. Qhov no yuav pab txheeb xyuas qhov tsis paub lossis kev tawm tsam tshiab.
Kev soj ntsuam raws tu qauv: IDS soj ntsuam kev siv network raws tu qauv thiab kuaj xyuas tus cwj pwm uas tsis ua raws li cov txheej txheem kev cai, yog li txheeb xyuas qhov kev tawm tsam tuaj yeem.
Hom IDS
Nyob ntawm qhov chaw lawv tau xa mus, IDS tuaj yeem muab faib ua ob hom loj:
Network IDS (NIDS): Deployed nyob rau hauv ib lub network los saib xyuas tag nrho cov tsheb khiav los ntawm lub network. Nws tuaj yeem ntes ob lub network thiab thauj txheej tawm tsam.
Host IDS (HIDS): Deployed ntawm ib tus tswv tsev los saib xyuas kev ua haujlwm ntawm tus tswv tsev ntawd. Nws tau tsom ntau dua rau kev kuaj xyuas tus tswv-theem kev tawm tsam xws li malware thiab tus neeg siv tus cwj pwm txawv txav.
IPS (Intrusion Prevention System) yog dab tsi?
Kev txhais ntawm IPS
Intrusion tiv thaiv tshuab yog cov cuab yeej kev ruaj ntseg uas siv cov kev tiv thaiv kev tiv thaiv los yog tiv thaiv kev tawm tsam tom qab kuaj pom lawv. Piv nrog IDS, IPS tsis yog tsuas yog ib qho cuab yeej rau kev saib xyuas thiab ceeb toom, tab sis kuj yog ib qho cuab yeej uas tuaj yeem cuam tshuam thiab tiv thaiv kev hem thawj.
IPS ua haujlwm li cas
IPS tiv thaiv lub kaw lus los ntawm kev ua haujlwm thaiv cov tsheb tsis zoo uas ntws los ntawm lub network. Nws lub ntsiab haujlwm tseem ceeb suav nrog:
Blocking Attack Traffic: Thaum IPS kuaj pom muaj peev xwm nres tsheb, nws tuaj yeem ntsuas tam sim los tiv thaiv cov tsheb khiav mus rau hauv lub network. Qhov no pab tiv thaiv kev nthuav tawm ntxiv ntawm kev tawm tsam.
Resetting lub xeev kev sib txuas: IPS tuaj yeem rov pib dua lub xeev kev sib txuas nrog rau qhov muaj peev xwm tawm tsam, yuam tus neeg tawm tsam rov tsim qhov kev sib txuas thiab yog li cuam tshuam qhov kev tawm tsam.
Hloov cov cai Firewall: IPS tuaj yeem hloov kho cov kev cai ntawm firewall los thaiv lossis tso cai rau qee yam kev khiav tsheb kom hloov mus rau qhov xwm txheej tiag tiag.
Hom IPS
Zoo ib yam li IDS, IPS tuaj yeem muab faib ua ob hom loj:
Network IPS (NIPS): Deployed nyob rau hauv ib lub network los saib xyuas thiab tiv thaiv kev tawm tsam thoob plaws hauv lub network. Nws tuaj yeem tiv thaiv cov txheej txheem network thiab thauj txheej tawm tsam.
Host IPS (HIPS): Muab tso rau ntawm ib tus tswv tsev los muab kev tiv thaiv ntau dua, feem ntau yog siv los tiv thaiv tus tswv tsev qib kev tawm tsam xws li malware thiab kev siv.
Dab tsi yog qhov txawv ntawm Intrusion Detection System (IDS) thiab Intrusion Prevention System (IPS)?
Txoj kev sib txawv ntawm kev ua haujlwm
IDS yog ib qho kev saib xyuas tsis zoo, feem ntau yog siv rau kev tshawb nrhiav thiab lub tswb. Hauv qhov sib piv, IPS yog qhov ua tau zoo thiab muaj peev xwm ntsuas los tiv thaiv kev tawm tsam.
Risk thiab Effect Comparison
Vim yog qhov tsis zoo ntawm IDS, nws yuav plam lossis qhov tsis zoo, thaum lub zog tiv thaiv ntawm IPS tuaj yeem ua rau muaj kev sib raug zoo hluav taws. Yuav tsum muaj kev sib npaug ntawm kev pheej hmoo thiab kev ua tau zoo thaum siv ob lub tshuab.
Deployment and Configuration Differences
IDS feem ntau hloov pauv tau thiab tuaj yeem xa mus rau ntau qhov chaw hauv lub network. Hauv qhov sib piv, kev xa tawm thiab teeb tsa ntawm IPS yuav tsum tau ua tib zoo npaj kom tsis txhob cuam tshuam nrog kev khiav tsheb ib txwm muaj.
Integrated Application ntawm IDS thiab IPS
IDS thiab IPS ntxiv rau ib leeg, nrog rau kev saib xyuas IDS thiab muab kev ceeb toom thiab IPS noj cov kev tiv thaiv tiv thaiv thaum tsim nyog. Kev sib xyaw ua ke ntawm lawv tuaj yeem tsim kom muaj kev sib txuas lus network kev ruaj ntseg tiv thaiv kab.
Nws yog ib qho tseem ceeb kom hloov kho cov cai, kos npe, thiab kev hem thawj ntawm IDS thiab IPS. Cyber kev hem thawj tau hloov zuj zus mus tas li, thiab kev hloov kho raws sijhawm tuaj yeem txhim kho lub peev xwm los txheeb xyuas cov kev hem thawj tshiab.
Nws yog ib qho tseem ceeb kom ua raws li cov cai ntawm IDS thiab IPS rau qhov tshwj xeeb network ib puag ncig thiab cov cai ntawm lub koom haum. Los ntawm kev hloov kho cov cai, qhov tseeb ntawm qhov system tuaj yeem txhim kho thiab qhov tsis zoo thiab kev raug mob tus phooj ywg tuaj yeem raug txo.
IDS thiab IPS yuav tsum muaj peev xwm teb tau cov kev hem thawj ntawm lub sijhawm. Cov lus teb nrawm thiab raug pab txhawm rau tiv thaiv cov neeg tawm tsam los ntawm kev ua kom puas tsuaj ntau hauv lub network.
Kev soj ntsuam tas li ntawm kev sib txuas hauv network thiab kev nkag siab ntawm cov qauv tsheb ib txwm tuaj yeem pab txhim kho qhov tsis pom kev muaj peev xwm ntawm IDS thiab txo qhov muaj peev xwm ntawm qhov tsis zoo.
