Qhov tsis muaj zog Zero-Day yog dab tsi?

Qhov tsis muaj zog hnub xoom yog qhov tsis muaj zog hauv software lossis kho vajtse uas tus muag khoom tsis paub, tsis muaj kev kho kom raug, txhais tau tias cov neeg tawm tsam tuaj yeem siv nws ua ntej muaj kev kho.

Lo lus no tau siv thawj zaug thaum kawg ntawm lub xyoo pua 20th, thiab thawj zaug piav txog kev nyiag khoom software, piv rau qhov tsis muaj zog software. Thawj zaug nws tau siv los piav txog cov software tshiab uas tau tawg thiab faib rau tib hnub (zero days) raws li nws qhov kev tso tawm raug cai. Tom qab ntawd, nws tau hloov mus rau cybersecurity (thaum ntxov xyoo 2000) thiab nws pib piav txog qhov tsis muaj zog kev ruaj ntseg uas cov neeg muag khoom software tsis paub thiab tsis muaj cov kho kom raug. Cov lus "zero-day vulnerability" tau lees paub dav hauv cov voj voog cybersecurity. Lub caij no, cov neeg ua phem hem thawj tau pib siv cov qhov tsis muaj zog no (zero-day vulnerability exploits) ua ntej cov neeg muag khoom tuaj yeem teb.

Lub ntsiab lus ntawm Zero-Day Vulnerabilities #

Lo lus no hais txog qhov tsis zoo ntawm kev ruaj ntseg hauv software lossis kho vajtse. Ib qho ntawm nws cov yam ntxwv tseem ceeb yog tias cov neeg muag khoom lossis cov neeg tsim khoom tsis paub txog qhov ntawd. "Zero-day" txhais tau tias cov neeg tsim khoom tau muaj xoom hnub los kho thiab kho cov qhov tsis zoo ua ntej lawv dhau los ua qhov tsis zoo thiab tom qab ntawd siv tsis raug.

Cov kev tsis muaj zog no muaj kev phom sij tshwj xeeb vim tias cov neeg ua phem tuaj yeem siv lawv ua ntej muaj kev ntsuas txo qis. Kev siv tsis muaj zog zero-day tuaj yeem ua rau nkag mus tsis tau tso cai, kev ua txhaum cai ntawm cov ntaub ntawv, lossis kev cuam tshuam ntawm lub kaw lus. Kev tsis muaj zog zero-day kuj tseem tuaj yeem siv los faib cov malware tsis paub los ntawm cov pob khoom software thib peb, suav nrog cov tsev qiv ntawv qhib thiab cov kev vam khom. Cov neeg tawm tsam siv cov qhov tsis zoo no los tso cov malware uas tseem tsis tau pom kom txog thaum muaj kev puas tsuaj loj.

Dab tsi ua rau muaj qhov tsis zoo ntawm Zero-Day?

#

Feem ntau lawv tshwm sim los ntawm qhov yuam kev coding, kev tsim qauv tsis zoo, lossis kev teeb tsa tsis raug uas tsim cov ntsiab lus nkag tsis tau xav tseg hauv software lossis kho vajtse systems. Vim tias cov neeg tsim khoom tsis paub txog cov qhov tsis zoo no, lawv tseem tsis tau kho thiab tuaj yeem raug siv tsis raug. Cov neeg tawm tsam thiab cov neeg ua phem uas muaj peev xwm txheeb xyuas cov qhov tsis zoo no tuaj yeem tsim cov kev siv tsis zoo zero-day, cov txheej txheem tshwj xeeb lossis cov cuab yeej tsim los siv cov qhov tsis zoo no los nkag mus rau hauv cov kab ke, rho tawm cov ntaub ntawv, lossis ua rau muaj kev cuam tshuam kev ua haujlwm.

Lub Neej Ib Txwm Muaj

• Tshawb pom: Ib tug neeg txheeb xyuas qhov tsis muaj zog. Nws tuaj yeem yog tus kws tshawb fawb txog kev ruaj ntseg, tus neeg nyiag khoom siv kev ncaj ncees, lossis txawm tias tus neeg ua phem uas xav siv nws.
• exploitationYog tias tus neeg ua phem pom qhov tsis zoo, lawv tuaj yeem siv nws tam sim ntawd los ntawm kev txhaj tshuaj malware rau hauv cov pob khoom software sab nraud uas siv dav. Txoj kev no ua rau muaj kev tawm tsam cov khoom xa tuaj, ua rau malware kis mus rau ntau lub koom haum ua ntej kev tshawb pom tshwm sim. Cov neeg tawm tsam kuj tseem siv nws los pib nkag mus rau cov ntaub ntawv tsis raug cai, kev ua txhaum cai ntawm lub cev, lossis software backdoors.
• Disclosure: Thaum pom tau qhov teeb meem no, tus neeg ntawd yuav xaiv qhia qhov teeb meem ntawd. Yog tias tus neeg tshawb pom qhov teeb meem ntawd ua los ntawm kev ncaj ncees, feem ntau lawv yuav qhia rau tus neeg muag khoom lossis los ntawm cov kev pab cuam qhia tawm uas muaj lub luag haujlwm; yog tias, qhov teeb meem ntawd yog los ntawm tus neeg ua phem, lawv yuav muag cov ntaub ntawv ntawd rau hauv lub vas sab tsaus ntuj lossis siv rau kev tau txiaj ntsig ntawm tus kheej.
• Kev Tsim Kho Daim Ntawv Kho: Thaum tus neeg muag khoom paub txog qhov tsis muaj zog, lawv yuav xub tsim ib qho kho lossis hloov tshiab los kho qhov tsis muaj zog. Lub sijhawm uas yuav tsum tau siv rau cov txheej txheem no sib txawv raws li qhov nyuaj ntawm qhov tsis muaj zog thiab cov qauv ntawm lub kaw lus.
• Txeeb: Tom qab kev tsim kho tiav lawm, daim ntawv kho tshiab yuav raug tso tawm rau cov neeg siv. Kev xa tawm raws sijhawm yog qhov tseem ceeb heev rau kev txo cov kev pheej hmoo ntawm kev siv tsis raug.

Cov Tswv Yim Tiv Thaiv Kev Siv Tsis Zoo ntawm Zero-Day Vulnerability #

Kev tiv thaiv kom tsis txhob muaj qhov teeb meem zero-day vulnerability yog qhov nyuaj heev (vim nws tsis paub meej). Rau qhov ntawd, cov koom haum tuaj yeem siv qee txoj hauv kev los txo cov kev pheej hmoo:

• Kev Hloov Kho Tshiab Tsis Tu Ncua: Xyuas kom tseeb tias txhua lub tshuab thiab cov ntawv thov tau hloov kho tsis tu ncua thiab lawv suav nrog cov kho tshiab tshaj plaws.

• Intrusion Detection Systems (IDS): Siv IDS los saib xyuas cov tsheb khiav hauv network rau cov qauv tsis zoo uas yuav qhia tau tias muaj kev sim siv qhov tsis muaj zog hauv zero-day

• Kev Ntsuas Tus Cwj Pwm: Xyuas kom tseeb tias koj siv cov kev daws teeb meem kev ruaj ntseg uas tshuaj xyuas tus cwj pwm ntawm daim ntawv thov kom nrhiav pom qhov txawv txav qhia txog kev siv tsis pub dhau hnub xoom

• Network Segmentation: Faib lub network ua ntu kom muaj kev cuam tshuam thiab tiv thaiv kev txav mus los ntawm cov neeg tawm tsam
• Kev Tshawb Nrhiav Kev hem thawj tsis siv neeg hauv Software Dependencies: Siv kev ruaj ntseg daws teeb meem uas tshuaj xyuas cov pob khoom software sab nraud thiab qhib-qhov chaw rau cov malware zais cia thiab qhov tsis zoo, pab nrhiav cov kev siv tsis zoo zero-day uas siv los kis cov code phem.
• Kev cob qhia neeg siv: Nco ntsoov qhia koj cov neeg ua haujlwm txog kev coj ua zoo tshaj plaws hauv kev ruaj ntseg hauv cyber, suav nrog kev lees paub qhov kev sim phishing thiab zam kev rub tawm uas tsis ntseeg siab
