Network Security vs Information Security
Kev ruaj ntseg hauv lub network cuam tshuam nrog cov txheej txheem lossis kev coj ua siv los tiv thaiv lub khoos phis tawj network los ntawm kev nkag mus tsis raug cai, siv tsis raug lossis hloov kho. Cov tes hauj lwm uas muaj los ntawm cov koom haum sib txawv xav tau ntau qib kev ruaj ntseg. Piv txwv li, theem kev ruaj ntseg xav tau los ntawm lub tsev network yuav txawv dua li qib kev ruaj ntseg xav tau los ntawm lub network ntawm kev koom tes loj. Ib yam li ntawd, cov ntaub ntawv kev ruaj ntseg tiv thaiv kev nkag mus tsis raug cai, siv tsis raug thiab hloov kho rau cov ntaub ntawv xov xwm thiab qhov tseem ceeb nws tiv thaiv cov ntaub ntawv.
Network Security yog dab tsi?
Kev ruaj ntseg network cuam tshuam nrog kev tiv thaiv lub network los ntawm kev nkag tsis tau tso cai. Thawj kauj ruam ntawm cov txheej txheem no yog authenticating tus neeg siv. Feem ntau, tus username thiab password yog siv rau qhov no. Qhov no yog hu ua one-factor authentication. Tsis tas li ntawd, koj tuaj yeem siv ob-yam lossis peb-qhov kev lees paub qhov tseeb uas suav nrog kev txheeb xyuas cov ntiv tes lossis cov cim kev ruaj ntseg. Tom qab kev lees paub tus neeg siv, lub firewall yog siv los xyuas kom meej tias tus neeg siv nkag tau tsuas yog cov kev pabcuam uas tau tso cai rau nws. Ntxiv nrog rau kev txheeb xyuas cov neeg siv, lub network yuav tsum tau muab kev tiv thaiv kev tiv thaiv kab mob hauv computer, worms lossis Trojans. Txhawm rau tiv thaiv lub network los ntawm cov software tiv thaiv kab mob no thiab kev tiv thaiv kev nkag mus (IPS) tuaj yeem siv. Raws li tau hais ua ntej, ntau hom kev tes hauj lwm sib txawv yuav tsum muaj kev ruaj ntseg sib txawv. Rau ib lub network me me ntawm ib lub tsev lossis ib lub lag luam me, qhov yooj yim firewall, antivirus software thiab cov passwords ruaj khov yuav txaus, thaum lub network ntawm ib lub koom haum tseem ceeb ntawm tsoomfwv yuav xav tau kev tiv thaiv siv lub firewall thiab proxy, encryption, muaj zog antivirus software thiab ob-lossis peb-factor authentication system, thiab lwm yam.
Dab tsi yog kev ruaj ntseg?
Cov ntaub ntawv kev ruaj ntseg yog cuam tshuam nrog kev tiv thaiv cov ntaub ntawv los ntawm kev nkag mus rau hauv ob txhais tes ntawm cov neeg tsis tau tso cai. Raws li kev lig kev cai, cov ntsiab cai tseem ceeb ntawm kev ruaj ntseg cov ntaub ntawv raug suav hais tias yog muab kev ceev ntiag tug, kev ncaj ncees thiab muaj. Tom qab ntawd, qee cov ntsiab lus xws li kev muaj, qhov tseeb thiab kev siv hluav taws xob tau raug npaj. Kev tsis pub leej twg paub txog kev tiv thaiv cov ntaub ntawv los ntawm kev nkag mus rau cov tog neeg tsis tau tso cai. Kev ncaj ncees ua kom paub tseeb tias cov ntaub ntawv tsis tuaj yeem hloov pauv tsis pub leej twg paub. Muaj kev txhawj xeeb txog seb cov ntaub ntawv puas muaj thaum lawv xav tau. Muaj kuj ua kom paub tseeb tias cov ntaub ntawv kaw lus tsis raug cuam tshuam rau kev tawm tsam xws li kev tsis lees paub ntawm kev pabcuam (DOS). Authenticity yog ib qho tseem ceeb rau kev txheeb xyuas tus kheej ntawm ob tog koom nrog kev sib txuas lus (uas nqa cov ntaub ntawv). Tsis tas li ntawd, kev ruaj ntseg cov ntaub ntawv siv cryptography, tshwj xeeb tshaj yog thaum hloov cov ntaub ntawv. Cov ntaub ntawv yuav raug encrypted xws li tias nws yuav siv tsis tau rau lwm tus uas tsis yog cov neeg siv tau tso cai.
Qhov txawv ntawm Network Security thiab Cov Ntaub Ntawv Kev Ruaj Ntseg yog dab tsi?
Kev ruaj ntseg hauv Is Taws Nem suav nrog cov txheej txheem lossis kev coj ua siv los tiv thaiv lub khoos phis tawj network los ntawm kev nkag mus tsis raug cai, siv tsis raug lossis hloov kho, thaum Cov Ntaub Ntawv Kev Nyab Xeeb tiv thaiv kev nkag tsis raug cai, siv tsis raug thiab hloov kho rau cov ntaub ntawv xov xwm. Hauv kev xyaum, software thiab cov cuab yeej siv los ua kom tiav kev ruaj ntseg network thiab cov ntaub ntawv kev ruaj ntseg yuav sib tshooj. Piv txwv li, antivirus software, firewalls thiab authentication schemes yuav tsum tau ua hauj lwm los ntawm ob txoj hauj lwm. Tab sis cov hom phiaj sim ua kom tiav los ntawm kev siv lawv txawv. Tsis tas li ntawd, ob txoj haujlwm no ntxiv rau ib leeg hauv kev nkag siab yog tias koj tsis tuaj yeem paub tseeb tias lub network muaj kev nyab xeeb, koj tsis tuaj yeem lav tias cov ntaub ntawv hauv lub network ruaj ntseg.
