CVE Vulnerability yog dab tsi?
Introduction
Ib qho CVE (Common Vulnerabilities thiab Exposures) qhov tsis zoo yog qhov tsis zoo rau kev tshaj tawm cybersecurity uas cuam tshuam rau ib qho software lossis cov kab ke. Cov vulnerabilities no tuaj yeem siv los ntawm cybercriminals kom tau txais kev tso cai nkag mus rau cov tshuab, nyiag cov ntaub ntawv rhiab, lossis cuam tshuam kev ua haujlwm ib txwm muaj.
CVE Vulnerabilities pom tau li cas?
CVE vulnerabilities feem ntau raug txheeb xyuas thiab tshaj tawm los ntawm cybersecurity soj ntsuam, uas tom qab ntawd ua haujlwm nrog cov software cuam tshuam los yog cov chaw tsim khoom los tsim ib thaj chaw lossis kho kom daws qhov teeb meem. Cov thaj ua rau thaj no feem ntau yog tso tawm los ua ib feem ntawm kev hloov kho software tsis tu ncua, thiab nws yog ib qho tseem ceeb rau cov neeg siv kom lawv cov tshuab hloov tshiab kom ntseeg tau tias lawv muaj kev tiv thaiv tiv thaiv qhov tsis zoo.
CVE Vulnerabilities muaj npe li cas?
Txhua qhov CVE qhov tsis zoo yog muab tus cim tshwj xeeb, hu ua CVE ID. Qhov kev txheeb xyuas no muaj cov lej thiab cov tsiaj ntawv, thiab siv los taug qab thiab siv qhov tshwj xeeb qhov tsis zoo. Piv txwv li, ib tus CVE ID yuav raug formatted li "CVE-2022-0001."
CVE Vulnerabilities Classified Li Cas?
CVE vulnerabilities raug cais raws li qhov hnyav ntawm lub peev xwm kev cuam tshuam lawv muaj peev xwm muaj. Lub National Vulnerability Database (NVD), uas yog tswj hwm los ntawm National Institute of Standards and Technology (NIST), siv cov txheej txheem kev ntsuas qhov hnyav los txheeb xyuas CVE qhov tsis zoo. Qhov system no suav nrog plaub theem hnyav:
- Tsawg: Qhov tsis zoo uas muaj peev xwm cuam tshuam tsawg, xws li cov uas tuaj yeem siv tau raws li qhov tsis tshua muaj tshwm sim lossis xav tau kev sib cuam tshuam nrog cov neeg siv tseem ceeb.
- Nruab Nrab: Cov kev tsis zoo uas muaj qhov cuam tshuam me ntsis, xws li cov uas tuaj yeem siv tau los ntawm kev deb tab sis xav tau qee theem ntawm cov neeg siv kev sib cuam tshuam.
- Tseem ceeb: Cov kev tsis zoo uas muaj qhov cuam tshuam loj heev, xws li cov uas tuaj yeem siv tau los ntawm kev deb yam tsis muaj kev cuam tshuam nrog cov neeg siv.
- Tseem Ceeb: Cov kev tsis zoo uas muaj qhov cuam tshuam tseem ceeb, xws li cov uas tuaj yeem siv tau nyob deb tsis muaj kev cuam tshuam nrog cov neeg siv thiab tuaj yeem ua rau muaj kev siv dav dav lossis cov ntaub ntawv tseem ceeb.
Koj tuaj yeem tiv thaiv CVE Vulnerabilities li cas?
Muaj ob peb kauj ruam uas koj tuaj yeem ua los tiv thaiv koj tus kheej thiab koj lub cev tiv thaiv kev paub txog CVE qhov tsis zoo:
- Ua kom koj lub tshuab hloov tshiab nrog cov thaj ua rau thaj tshiab thiab hloov tshiab software. Qhov no tseem ceeb heev rau operating systems, web browsers, thiab lwm yam software uas nquag hloov kho los daws cov teeb meem tshiab.
- Siv cov software tiv thaiv kab mob los tiv thaiv kev tawm tsam malware uas tuaj yeem siv qhov tsis zoo.
- Siv lub firewall los thaiv kev nkag mus rau koj lub tshuab tsis raug cai.
- Siv cov passwords muaj zog thiab hloov kho lawv tsis tu ncua kom nws nyuaj rau cybercriminals kom nkag mus rau koj cov nyiaj.
- Siv ob-factor authentication (2FA) ntxiv ib txheej ntxiv ntawm kev tiv thaiv rau koj cov nyiaj.
Los ntawm kev ua raws li cov kev coj ua zoo tshaj no, koj tuaj yeem pab tiv thaiv koj tus kheej thiab koj lub cev tiv thaiv kev paub txog CVE qhov tsis zoo thiab txo qhov kev pheej hmoo ntawm kev tawm tsam cyber.
xaus
Hauv kev xaus, CVE qhov tsis zoo yog qhov tsis muaj kev tiv thaiv cybersecurity uas cuam tshuam rau cov software tshwj xeeb lossis cov kab ke. Cov kev tsis zoo no tuaj yeem muaj qhov sib txawv ntawm qhov hnyav thiab tuaj yeem siv los ntawm cybercriminals kom tau txais kev tso cai tsis raug cai, nyiag cov ntaub ntawv rhiab, lossis cuam tshuam kev ua haujlwm ib txwm muaj. Nws yog ib qho tseem ceeb uas yuav tsum ua kom koj lub tshuab hloov tshiab nrog cov thaj ua rau thaj tshiab thiab kev hloov kho software, siv software antivirus thiab firewall, siv cov passwords muaj zog thiab siv ob qhov kev lees paub tseeb, thiab ua raws li lwm cov kev coj ua zoo tshaj plaws los tiv thaiv kev paub txog CVE vulnerabilities thiab txo qhov kev pheej hmoo. ntawm kev tawm tsam cyber.
