Hauv thaj teb kev ruaj ntseg, intrusion nrhiav cov txheej txheem (ID) thiab kev tiv thaiv tus kheej (IPS) ua lub luag haujlwm tseem ceeb. Kab lus no yuav tob dhau lawv cov lus txhais, cov luag haujlwm, qhov sib txawv, thiab daim ntawv thov kev xaiv.
Dab tsi yog ids (intrusion nrhiav cov kab ke)?
Kev txhais ntawm ID
Cov kev tshawb nrhiav tau yog cov khoom siv ruaj ntseg uas saib xyuas cov neeg saib xyuas thiab tshuaj xyuas cov haujlwm network los txheeb cov dej num ua tej yam uas tsis zoo lossis tawm tsam. Nws tshawb rau kev kos npe uas phim paub tias kev tawm tsam cov qauv los ntawm kev kuaj xyuas cov tsheb network, cov cav system, thiab lwm yam ntaub ntawv cuam tshuam.
Cas ids ua haujlwm
Ids ua haujlwm tsuas yog nyob rau hauv txoj kev hauv qab no:
Kev kuaj kom raug kos npe kos npe: IDS siv lub npe kos npe ntawm cov qauv kev tawm tsam rau kev sib txuam, zoo ib yam li cov kab mob kab mob rau ntes cov kab mob. Ids tsa qhov kev ceeb toom thaum cov tsheb muaj cov nta uas phim cov kos npe no.
Kev saib xyuas anomaly: Tus lej ID tau saib xyuas ib lub hauv paus ntawm cov haujlwm network ib txwm muaj thiab cov kev ceeb toom thaum nws pom cov qauv uas txawv ntawm tus cwj pwm zoo li qub. Qhov no pab txheeb xyuas qhov tsis paub lossis kev tawm tsam tshiab.
Kev txheeb xyuas cov txheej txheem: IDS tsom xam kev siv ntawm cov kev cai network thiab kuaj pom tus cwj pwm uas tsis ua raws li cov qauv kev sib raug zoo.
Hom ID
Ua raws qhov uas lawv tau tso tawm, ID tuaj yeem muab faib ua ob hom loj:
Network ID (Nids): Xa mus rau hauv lub network los saib xyuas txhua txoj kev khiav tsheb los ntawm lub network. Nws tuaj yeem kuaj pom ob lub network thiab thauj txheej txheej kev tawm tsam.
Tus tswv tsev ID (HIDS): Xa tawm ntawm ib tus tswv tsev ib leeg los saib xyuas kev ua haujlwm ntawm tus tswv tsev. Nws yog ntau tshaj plaws ntawm kev kuaj seb tus tswv yim nce xws li malware thiab tsis txaus ntseeg tus cwj pwm.
IPS (kev tiv thaiv kev tiv thaiv) yog dab tsi?
Txhais ntawm IPS
Interusion Tiv Thaiv Cov Tshuab yog cov cuab yeej ruaj ntseg uas tau siv cov kev ntsuas ua tiav cov khoom muag kom nres lossis tiv thaiv qhov kev tawm tsam muaj peev xwm tom qab kuaj xyuas lawv. Piv nrog IDS, IPS tsis yog tsuas yog ib qho cuab yeej rau kev soj ntsuam thiab kev ceeb toom, tab sis kuj yog pab cuam tshuam thiab tiv thaiv kev hem thawj.
Yuav ua li cas IPS ua haujlwm
IPS tiv thaiv lub system los ntawm kev taug qab thaiv cov tsheb khiav tsis zoo los ntawm lub network. Nws lub ntsiab ua hauj lwm cov cai suav nrog:
Thaiv kev nres tsheb: Thaum IPS ntes tau cov tsheb khiav tawm, nws tuaj yeem ua ntsuas cov tsheb tam sim los tiv thaiv cov tsheb khiav ntawm cov network. Qhov no pab tiv thaiv kom tsis txhob tshaj tawm kev tawm tsam ntxiv.
Rov qab pib lub xeev kev sib txuas: IPS tuaj yeem rov pib dua lub xeev kev sib txuas nrog kev tawm tsam, yuam tus neeg tawm tsam kom rov tsim qhov kev sib txuas thiab yog li cuam tshuam kev tawm tsam.
Hloov Cov Kev Cai Hluav Taws Xob Hluav Taws Xob: Ips tuaj yeem hloov kho cov kab ntsig firewall los thaiv lossis cia cov tsheb khiav tshwj xeeb kom haum rau cov xwm txheej tiag tiag.
Hom IPS
Zoo ib yam li IDS, IPS tuaj yeem muab faib ua ob hom loj:
Network Ips (NIPS): Xa tawm 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 network txheej thiab thauj txheej txheej.
Tus Thawj Coj Ips (HIPS): Xa tawm ntawm ib tus tswv tsev ib leeg los muab cov kev tiv thaiv ntau dua, feem ntau siv los tiv thaiv cov qib siab xws li malware thiab siv tau.
Dab tsi yog qhov sib txawv ntawm cov intrusion nrhiav cov txheej txheem (ID) thiab kev tiv thaiv kev tiv thaiv (IPS)?
Txoj kev sib txawv ntawm kev ua haujlwm
Daim ID yog lub tshuab saib xyuas passive, tsuas yog siv rau kev kuaj thiab tswb. Hauv kev sib piv, IPS yog proactive thiab muaj peev xwm coj kev ntsuas los tiv thaiv kev tawm tsam muaj peev xwm.
Kev pheej hmoo thiab cov kev sib piv
Vim yog lub passive ntawm ids, nws yuav plam lossis tsis tseeb pom tseeb, thaum cov kev tiv thaiv nquag tuaj yeem ua rau muaj hluav taws. Muaj kev yuav tsum tau sib npaug kev pheej hmoo thiab ua haujlwm tau zoo thaum siv ob qho system no.
Kev xa tawm thiab teeb tsa sib txawv
ID yog feem ntau yoog raws thiab tuaj yeem xa tawm ntawm cov chaw sib txawv hauv lub network. Nyob rau hauv kev sib piv, kev xa tawm thiab kev teeb tsa ntawm IPS yuav tsum tau ua tib zoo npaj kev npaj kom tsis txhob muaj kev cuam tshuam nrog kev tsheb khiav.
Daim Ntawv Thov Kev Cai ntawm ID thiab IPS
Ids thiab IPS sib txuam, nrog tus ID saib xyuas thiab muab kev ceeb toom thiab IPS kev ntsuas tiv thaiv kev tiv thaiv thaum tsim nyog. Kev sib xyaw ntawm lawv tuaj yeem tsim ib qho kev tiv thaiv kev ruaj ntseg network kev tiv thaiv kev nyab xeeb.
Nws yog qhov tseem ceeb kom hloov kho cov cai, kos npe, thiab kev hem thawj ntawm ID thiab IPS. Cyber hawv muaj kev hem paub tas li, thiab cov hloov tshiab raws sijhawm tuaj yeem txhim kho cov kab ke lub peev xwm los txheeb xyuas kev hem tshiab.
Nws yog qhov tseem ceeb rau kev ua kom cov cai ntawm ID thiab IPS rau qhov chaw network tshwj xeeb thiab kev xav tau ntawm lub koom haum. Los ntawm kev txheeb xyuas cov cai, qhov tseeb ntawm lub system tuaj yeem txhim kho thiab kev raug mob cuav tuaj yeem raug txo.
ID thiab IPS yuav tsum muaj peev xwm teb tau rau cov peev xwm kev hem thawj ntawm lub sijhawm. Ib cov lus teb sai thiab raug pab cuam tshuam rau cov kev tawm tsam los ntawm kev ua rau muaj kev puas tsuaj ntau hauv lub network.
Nruam kev saib xyuas ntawm network tsheb thiab kev nkag siab ntawm cov qauv tsheb khiav ib txwm tuaj yeem pab txhim kho qhov muaj peev xwm kuaj pom kev paub txog tus ID thiab txo qhov tau ntawm cov cuav cuav.
