Hauv cov toj roob hauv pes nrawm nrawm ntawm kev sib tham niaj hnub no, kev hloov pauv ntawm Local Area Networks (LANs) tau ua txoj hauv kev rau cov kev daws teeb meem tshiab kom tau raws li qhov nyuaj ntawm cov koom haum xav tau. Ib qho kev daws teeb meem uas sawv tawm yog Virtual Local Area Network, lossis VLAN. Kab lus no delves rau hauv intricacies ntawm VLANs, lawv lub hom phiaj, qhov zoo, kev ua piv txwv, kev coj ua zoo tshaj plaws, thiab lub luag haujlwm tseem ceeb uas lawv tau ua hauv kev hloov mus rau qhov kev xav tau hloov zuj zus ntawm network infrastructure.
I. Nkag siab VLANs thiab Lawv Lub Hom Phiaj
Virtual Local Area Networks, los yog VLANs, rov txhais lub tswv yim ib txwm muaj ntawm LANs los ntawm kev qhia ib txheej virtualized uas ua rau cov koom haum tuaj yeem ntsuas lawv cov tes hauj lwm nrog qhov loj, hloov tau, thiab nyuaj. VLANs yog qhov tseem ceeb ntawm cov khoom siv lossis cov kab sib txuas uas sib txuas lus zoo li yog ib feem ntawm ib qho LAN, thaum qhov tseeb, lawv muaj nyob hauv ib lossis ob peb ntu LAN. Cov ntu no raug cais tawm ntawm qhov seem ntawm LAN los ntawm cov txuas hniav, routers, lossis cov keyboards, tso cai rau kev ntsuas kev nyab xeeb thiab txo qis network latency.
Cov kev piav qhia ntawm VLAN ntu cuam tshuam nrog lawv qhov kev sib cais los ntawm qhov dav LAN. Qhov kev rho tawm no hais txog cov teeb meem tshwm sim hauv LANs ib txwm muaj, xws li cov teeb meem tshaj tawm thiab kev sib tsoo. VLANs ua raws li "kev sib tsoo thawj," txo qhov xwm txheej ntawm kev sib tsoo thiab ua kom zoo dua cov peev txheej network. Qhov kev ua haujlwm zoo dua ntawm VLANs txuas ntxiv rau cov ntaub ntawv kev ruaj ntseg thiab kev sib faib cov ntsiab lus, qhov twg VLANs tuaj yeem muab faib ua pawg raws li cov tuam haujlwm, pab pawg ua haujlwm, lossis lwm yam kev sib koom tes hauv lub hauv paus ntsiab lus.
II. Vim li cas thiaj siv VLANs
Cov koom haum tau txais txiaj ntsig zoo los ntawm qhov zoo ntawm kev siv VLAN. VLANs muab cov txiaj ntsig zoo, vim tias chaw ua haujlwm hauv VLANs sib txuas lus los ntawm VLAN keyboards, txo qis kev cia siab ntawm routers, tshwj xeeb tshaj yog rau kev sib txuas lus sab hauv hauv VLAN. Qhov no tso cai rau VLANs kom tswj tau cov ntaub ntawv nce ntxiv, txo tag nrho lub network latency.
Qhov yooj yim dua hauv kev teeb tsa network yog lwm qhov laj thawj uas siv VLANs. Lawv tuaj yeem teeb tsa thiab muab tso rau raws li qhov chaw nres nkoj, raws tu qauv, lossis cov txheej txheem subnet, tso cai rau cov koom haum hloov VLANs thiab hloov cov qauv tsim network raws li xav tau. Ntxiv mus, VLANs txo cov kev tswj hwm kev siv zog los ntawm kev txwv tsis pub nkag mus rau cov neeg siv cov pab pawg, ua rau kev teeb tsa network thiab kev ntsuas kev ruaj ntseg zoo dua.
III. Piv txwv ntawm Kev Siv VLAN
Hauv qhov xwm txheej tiag tiag, cov lag luam uas muaj chaw ua haujlwm dav dav thiab pab pawg loj tau txais txiaj ntsig zoo los ntawm kev koom ua ke ntawm VLANs. Qhov yooj yim cuam tshuam nrog kev teeb tsa VLANs txhawb kev ua tiav ntawm kev ua haujlwm tsis sib haum xeeb thiab txhawb kev sib koom tes ntawm ntau lub tuam tsev. Piv txwv li, pab pawg tshwj xeeb hauv kev lag luam, kev muag khoom, IT, thiab kev txheeb xyuas kev lag luam tuaj yeem sib koom tes zoo thaum muab rau tib VLAN, txawm tias lawv qhov chaw nyob sib txawv ntawm cov plag tsev lossis cov tsev sib txawv. Txawm hais tias muaj peev xwm daws tau los ntawm VLANs, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov txog cov teeb meem uas muaj peev xwm, xws li VLAN tsis sib haum, txhawm rau ua kom muaj txiaj ntsig zoo ntawm cov tes hauj lwm no hauv ntau lub koom haum xwm txheej.
IV. Cov kev coj ua zoo tshaj plaws thiab kev saib xyuas
Kev tsim nyog VLAN yog qhov tseem ceeb rau kev siv lawv lub peev xwm tag nrho. Leveraging VLAN segmentation cov txiaj ntsig ua kom muaj kev sib txuas sai dua thiab ruaj ntseg dua, hais txog qhov xav tau ntawm kev hloov pauv mus rau cov kev xav tau hauv network. Managed Service Providers (MSPs) ua lub luag haujlwm tseem ceeb hauv kev tswj hwm VLAN, saib xyuas kev faib khoom, thiab ua kom muaj kev ua haujlwm txuas ntxiv mus.
| 10 Cov Kev Cai Zoo Tshaj Plaws | Lub ntsiab lus |
| Siv VLANs rau Segment Traffic | Los ntawm lub neej ntawd, cov khoom siv network sib txuas lus ywj pheej, ua rau muaj kev pheej hmoo nyab xeeb. VLANs hais qhov no los ntawm segmenting tsheb, txwv kev sib txuas lus rau cov khoom siv hauv tib VLAN. |
| Tsim ib tug Separate Management VLAN | Tsim kom muaj kev tswj hwm VLAN ua kom muaj kev ruaj ntseg network. Kev cais tawm kom ntseeg tau tias cov teeb meem hauv kev tswj hwm VLAN tsis cuam tshuam rau lub network dav. |
| Muab IP Chaw Nyob Zoo rau Kev Tswj VLAN | IP chaw nyob zoo ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas cov cuab yeej thiab kev tswj hwm network. Zam DHCP rau kev tswj hwm VLAN ua kom muaj kev sib txuas lus zoo, ua kom yooj yim rau kev tswj hwm network. Kev siv cov subnets sib txawv rau txhua VLAN txhim kho kev sib cais ntawm cov tsheb, txo qhov kev pheej hmoo ntawm kev nkag mus tsis tau. |
| Siv Tus IP Chaw Nyob Qhov Chaw rau Kev Tswj VLAN | Txhim khu kev ruaj ntseg, kev tswj hwm VLAN tau txais txiaj ntsig los ntawm qhov chaw nyob IP ntiag tug, tiv thaiv cov neeg tawm tsam. Kev ntiav cov kev tswj hwm VLANs sib txawv rau cov cuab yeej sib txawv ua kom muaj kev teeb tsa thiab kev sib koom ua ke rau kev tswj hwm network. |
| Tsis txhob siv DHCP ntawm Management VLAN | Kev taw qhia meej ntawm DHCP ntawm kev tswj hwm VLAN yog qhov tseem ceeb rau kev ruaj ntseg. Kev cia siab ib leeg ntawm qhov chaw nyob IP zoo li tiv thaiv kev nkag mus tsis tau tso cai, ua rau nws nyuaj rau cov neeg tawm tsam kom nkag mus rau hauv lub network. |
| Ruaj ntseg tsis siv Ports thiab lov tes taw cov kev pab cuam tsis tsim nyog | Cov chaw nres nkoj tsis siv tam sim no muaj peev xwm ua rau muaj kev nyab xeeb, caw kom nkag mus tsis tau. Disabling tsis siv cov chaw nres nkoj thiab cov kev pab cuam tsis tsim nyog minimizes attack vectors, txhawb kev ruaj ntseg network. Ib txoj hauv kev uas muaj feem cuam tshuam nrog kev soj ntsuam tas li thiab kev ntsuam xyuas ntawm cov kev pabcuam nquag. |
| Siv 802.1X Kev lees paub tseeb ntawm Kev Tswj VLAN | 802.1X authentication ntxiv ib txheej ntxiv ntawm kev ruaj ntseg los ntawm kev tso cai rau cov cuab yeej pov thawj nkaus xwb nkag mus rau kev tswj hwm VLAN. Qhov kev ntsuas no tiv thaiv cov cuab yeej tseem ceeb hauv lub network, tiv thaiv kev cuam tshuam los ntawm kev nkag mus tsis tau. |
| Qhib chaw nres nkoj ruaj ntseg ntawm Kev Tswj VLAN | Raws li cov ntsiab lus nkag siab, cov khoom siv hauv kev tswj hwm VLAN xav tau kev ruaj ntseg nruj. Chaw nres nkoj kev ruaj ntseg, teeb tsa kom tso cai tsuas yog MAC chaw nyob, yog ib txoj hauv kev zoo. Qhov no, ua ke nrog kev ntsuas kev nyab xeeb ntxiv xws li Access Control Lists (ACLs) thiab firewalls, txhim kho kev ruaj ntseg hauv network tag nrho. |
| Disable CDP ntawm Management VLAN | Thaum Cisco Discovery Protocol (CDP) pab tswj lub network, nws qhia txog kev pheej hmoo kev nyab xeeb. Disabling CDP ntawm kev tswj hwm VLAN txo cov kev pheej hmoo no, tiv thaiv kev nkag mus tsis tau thiab muaj peev xwm nthuav tawm cov ntaub ntawv xov xwm hauv lub network. |
| Configure ACL ntawm Management VLAN SVI | Access Control Lists (ACLs) ntawm kev tswj hwm VLAN Hloov Virtual Interface (SVI) txwv kev nkag mus rau cov neeg siv tau tso cai thiab cov tshuab. Los ntawm kev qhia qhov tso cai IP chaw nyob thiab subnets, qhov kev coj ua no txhawb kev ruaj ntseg network, tiv thaiv kev nkag mus rau qhov tseem ceeb ntawm kev tswj hwm kev ua haujlwm. |
Hauv kev xaus, VLANs tau tshwm sim los ua ib qho kev daws teeb meem, kov yeej cov kev txwv ntawm LANs ib txwm muaj. Lawv lub peev xwm los hloov mus rau qhov kev hloov pauv hauv lub network toj roob hauv pes, ua ke nrog cov txiaj ntsig ntawm kev ua haujlwm tau zoo, hloov tau yooj yim, thiab txo qis kev tswj hwm, ua rau VLANs tseem ceeb hauv kev sib tham niaj hnub no. Raws li cov koom haum tseem loj hlob tuaj, VLANs muab txoj hauv kev muaj peev xwm thiab muaj txiaj ntsig kom ua tau raws li cov kev cov nyom ntawm cov txheej txheem niaj hnub network.
