Kev nyab xeeb network hloov yog ib kauj ruam tseem ceeb hauv kev tiv thaiv tag nrho cov network txheej txheem. Raws li lub hauv paus taw tes ntawm cov ntaub ntawv kis, network hloov tau tuaj yeem dhau los ua cov hom phiaj ntawm kev tawm tsam cyber yog tias muaj qhov tsis muaj kev tiv thaiv cyber. Los ntawm cov kev hloov pauv hloov kev ruaj ntseg zoo tshaj plaws, koj tuaj yeem tiv thaiv koj lub tuam txhab cov lus qhia tseem ceeb los ntawm kev ua haujlwm tsis raug cai thiab kev ua phem.
1. Hloov lub neej ua pov thawj
Ntau lub tshuab hloov tuaj nrog lub npe siv uas usernames thiab password uas tuaj yeem yooj yim siv los ntawm cov neeg tawm tsam. Hloov cov peev xwm no kom muaj zog thiab tshwj xeeb yog thawj kauj ruam los tiv thaiv koj tus hloov. Siv kev sib txuas ntawm cov tsiaj ntawv, lej, thiab cov cim tshwj xeeb rau ntxiv lub zog.
2. Kev siv cov chaw nres nkoj tsis siv
Cov chaw nres nkoj tsis siv ntawm koj lub pob nyem tuaj yeem nkag cov ntsiab lus rau cov khoom siv tsis tau tso cai. Disabling cov chaw nres nkoj no txwv tsis pub muaj leej twg los ntawm kev sib txuas thiab nkag mus rau koj lub network yam tsis tau tso cai.
3. Siv Vlan rau Network Segmentation
Qhov chaw virtual Cheeb Tsam tes hauj lwm (Vlans) tso cai rau koj kom ntu koj lub network rau cov ntu sib txawv. Los ntawm kev cais tawm cov tshuab rhiab lossis cov khoom siv, koj tuaj yeem txwv txoj kev sib kis tau ntawm cov kev ua txhaum cai thiab ua rau nws nyuaj rau cov neeg tawm tsam mus nkag tau cov peev txheej tseem ceeb.
4. Ua kom muaj chaw nres nkoj ruaj ntseg
Lub chaw nres nkoj kev nyab xeeb tuaj yeem txwv cov khoom siv twg tuaj yeem txuas rau txhua qhov chaw nres nkoj ntawm lub pob nyem. Piv txwv li, koj tuaj yeem tsim lub chaw nres nkoj kom tso cai tsuas yog MAC chaw nyob kom tiv thaiv cov khoom siv tsis tau tso cai los ntawm kev nkag mus.
5. Khaws cov firmware kho tshiab
Hloov chaw tsim khoom ib txwm tso cov ntawv hloov kho firmware hloov kho kom zoo rau thaj kev ruaj ntseg tsis muaj zog. Nco ntsoov tias koj qhov hloov pauv tau khiav ntawm cov firmware tseeb kom tiv thaiv tawm tsam cov kev tiv thaiv tau paub.
6. Siv cov kev cai tswj kev ruaj ntseg
Zam kev siv cov txheej txheem tswjfwm unrecrypted xws li telnet. Hloov chaw, siv cov kev ruaj ntseg zoo xws li Ssh (lub plhaub zoo) lossis HTTPS los tswj tus hloov pauv los tiv thaiv cov ntaub ntawv rhiab los ntawm kev cuam tshuam.
7. Siv cov npe nkag nkag (ACLS)
Kev tswj hwm cov npe yuav txwv tsis pub muaj kev khiav tawm hauv thiab tawm ntawm qhov kev hloov pauv raws cov qauv tshwj xeeb, xws li tus IP addocol lossis raws tu qauv. Qhov no ua kom ntseeg tau tias tsuas yog cov neeg siv tau tso cai thiab cov khoom siv tuaj yeem sib txuas lus nrog koj lub network.
8. Saib xyuas cov tsheb thiab cov cav
Saib xyuas cov tsheb network network thiab hloov cov cav tsis tu ncua rau kev ua txawv txawv. Cov qauv txawv txawv xws li rov ua tiav cov npe nkag tau tuaj yeem qhia txog kev ua txhaum kev nyab xeeb.
9. Xyuas kom lub cev ruaj ntseg ntawm lub pob nyem
Tsuas yog cov neeg ua haujlwm raug cai yuav tsum muaj kev nkag mus rau lub cev. Nruab qhov hloov hauv chav tsev neeg rau zaub mov lossis txee kom tiv thaiv kev ua phem.
10. Pab kom 802.1x authentication
802.1x yog lub network nkag tswj cov txheej txheem uas yuav tsum tau siv cov khoom siv los kuaj xyuas lawv tus kheej ua ntej nkag mus rau lub network. Qhov no ntxiv ib txheej ntxiv ntawm kev tiv thaiv cov khoom siv tsis tau tso cai.
Kev xav kawg
Kev nyab xeeb network hloov yog ib qho txheej txheem txuas ntxiv uas yuav tsum muaj kev ceev faj thiab hloov tshiab tsis tu ncua. Los ntawm kev sib txuas ua ke nrog kev ua haujlwm zoo nrog kev coj ua zoo tshaj plaws, koj tuaj yeem txo qis kev pheej hmoo ntawm kev ruaj ntseg ua txhaum cai. Nco ntsoov, ib qho kev ruaj ntseg network pib nrog hloov chaw ruaj ntseg.
Yog tias koj tab tom nrhiav kev nyab xeeb thiab txhim khu kev qha network, peb cov pob hluav taws xob hloov tau nruab nrog cov nta kev nyab xeeb kom koj lub network muaj kev nyab xeeb.
