Yuav Paub
- Qhia txog kev hem thawj: Txheeb xyuas cov lus email lossis qauv. Tshawb xyuas URLs (tab sis tsis txhob nyem) kom pom tias lawv phim tus neeg xa ntawv thov tus kheej.
- Kev taw qhia dav dav: Tsis txhob muab cov ntaub ntawv ntiag tug, tsis txhob nyem lossis rub tawm cov txuas tsis txaus ntseeg, ua kom koj lub kaw lus hloov tshiab, ib txwm khaws koj cov ntaub ntawv.
- Hom kev tawm tsam cyber: Kawm qhov sib txawv ntawm cov kab mob, cov cab, thiab trojan nees.
Kev tawm tsam hauv cyber tuaj yeem siv ntau hom ntawv los ntawm kev cuam tshuam cov ntaub ntawv tus kheej mus rau kev tswj hwm lub khoos phis tawj thiab thov kom them tus nqe txhiv-feem ntau them rau hauv daim ntawv ntawm cryptocurrency-tso tawm qhov kev tswj hwm ntawd. Yog vim li cas cov kev tawm tsam no kis tau sai heev yog tias lawv feem ntau nyuaj rau pom.
Yuav ua li cas txheeb xyuas Cyber Atack

Ua kom koj lub cev mus txog hnub kawg. Hackers nyob rau cov khoos phis tawj uas tsis muaj hnub nyoog thiab tsis tau muaj kev ruaj ntseg hloov tshiab lossis thaj ua rau lub sijhawm ntev. Lawv tau kawm txog txoj hauv kev kom nkag tau rau koj lub computer, thiab yog tias koj tsis tau nruab qhov hloov tshiab lossis kev ruaj ntseg thaj ua rau thaj, ces koj tab tom qhib lub qhov rooj thiab caw lawv tuaj. Yog tias koj tuaj yeem tso cai hloov kho tsis siv neeg hauv koj lub computer, ua nws. Yog tias tsis yog, tom qab ntawd ua nws ib qho kev xyaum ua tam sim ntawd nruab cov hloov tshiab thiab thaj ua rau thaj kom sai li sai tau thaum koj tau ceeb toom lawv muaj. Ua kom koj lub cev mus txog hnub tim yog ib qho ntawm koj cov riam phom zoo tshaj plaws tiv thaiv kev tawm tsam cyber.
- Ib txwm muaj ib qho thaub qab. Yog tias txhua yam ua tsis tiav, muaj kev thaub qab ntawm tag nrho koj cov ntaub ntawv ua kom koj tuaj yeem rov qab mus rau qhov qub tsis muaj sijhawm.

Yog tias koj cov ntaub ntawv xaus encrypted, koj tuaj yeem rov qab los ntawm koj qhov thaub qab thiab ua tau zoo.
Yuav ua li cas Cyber Atacks tshwm sim
Kev nkag siab txog kev hem thawj cyber thiab kev tawm tsam cyber tsuas yog ib feem ntawm cov ntaub ntawv xav tau los tiv thaiv koj tus kheej. Koj yuav tsum paub tias kev tawm tsam cyber tshwm sim li cas. Feem ntau cov kev tawm tsam yog kev sib txuas ntawm cov lus sib txuas lus siv los yog, hauv cov ntsiab lus yooj yim, kev sim hloov tus neeg siv lub computer tus cwj pwm los ntawm qee qhov kev siv lub computer tsis zoo.
Phishing e-mails yog ib hom kev tawm tsam cyber-viruses lossis worms-siv los ntxias koj los muab cov ntaub ntawv lossis rub tawm cov ntaub ntawv uas cog cov lej hauv koj lub computer los nyiag koj cov ntaub ntawv. Cov txheej txheem no yog hom kev tawm tsam cyber.
Kev nkag siab Cyber Thiab
Ib qho ntawm qhov ua tau zoo tshaj plaws ntawm kev tawm tsam cyber yog tib neeg tus cwj pwm. Txawm tias qhov tseeb tshaj plaws, kev ruaj ntseg ruaj khov tsis tuaj yeem tiv thaiv koj yog tias koj qhib lub qhov rooj thiab cia tus neeg ua txhaum cai nkag mus. Yog vim li cas nws tseem ceeb kom paub tias kev hem thawj ntawm cyber yog dab tsi, yuav ua li cas pom qhov muaj peev xwm tawm tsam, thiab tiv thaiv koj tus kheej li cas.
Kev tawm tsam hauv cyber tuaj yeem faib ua ob lub thoob dav dav: kev tawm tsam syntactic thiab kev tawm tsam semantic.
Syntactic Cyber Attacks
Syntatic tawm tsam yog ntau hom kev phem software uas tawm tsam koj lub computer los ntawm ntau txoj kev.
Cov hom software uas nquag siv hauv kev tawm tsam syntactic suav nrog:
- Viruses: Tus kab mob yog ib qho ntawm cov software uas tuaj yeem txuas nws tus kheej mus rau lwm cov ntaub ntawv lossis qhov program los tsim tawm. Hom software no feem ntau pom nyob rau hauv cov ntaub ntawv rub tawm thiab email txuas. Thaum koj rub tawm cov ntawv txuas lossis pib rub tawm, tus kab mob tau qhib, nws rov ua dua, thiab xa nws tus kheej mus rau txhua tus hauv koj cov ntaub ntawv tiv tauj.
- Worms: Cov kab mob tsis xav tau lwm cov ntaub ntawv lossis kev pab cuam los rov ua dua thiab sib kis. Cov me me ntawm cov software no kuj muaj ntau dua thiab tuaj yeem sau thiab xa cov ntaub ntawv mus rau qhov chaw tshwj xeeb siv cov ntaub ntawv hais txog lub network uas nws nyob. Tus kab mob kis rau lub computer thaum nws xa los ntawm lwm daim software ntawm lub network. Qhov no yog vim li cas cov tuam txhab lag luam feem ntau raug kev tawm tsam cyber ntau vim tias tus kab mob kis tau los ntawm lub network.
- Trojan Nees: Zoo li Trojan nees siv los ntawm Greeks hauv Trojan Tsov Rog, cyber Trojan nees zoo li ib yam dab tsi tsis muaj tseeb, tab sis qhov tseeb yog zais qee yam tsis zoo. Tus nees Trojan tuaj yeem yog email uas zoo li nws los ntawm lub tuam txhab ntseeg siab, thaum qhov tseeb, nws tau xa los ntawm cov neeg ua phem lossis cov neeg ua phem phem.
Semantic Cyber Attacks
Kev tawm tsam yog ntau ntxiv txog kev hloov kev nkag siab lossis kev coj cwj pwm ntawm tus neeg lossis lub koom haum uas raug tawm tsam. Tsis muaj kev tsom mus rau cov software koom nrog.
Piv txwv li, kev tawm tsam phishing yog hom kev tawm tsam semantic. Phishing tshwm sim thaum tus neeg ua yeeb yam tsis zoo xa email sim sau cov ntaub ntawv los ntawm cov neeg tau txais. Cov e-mail feem ntau zoo li yog los ntawm lub tuam txhab uas koj ua lag luam, thiab nws hais tias koj tus account tau raug cuam tshuam. Koj raug qhia kom nyem los ntawm qhov txuas thiab muab cov ntaub ntawv tshwj xeeb los txheeb xyuas koj tus as khauj.
Phishing tawm tsam tuaj yeem raug tua siv software thiab tuaj yeem suav nrog cov kab mob lossis kab mob, tab sis lub ntsiab lus tseem ceeb ntawm hom kev tawm tsam no yog kev sib raug zoo-kev sim hloov tus cwj pwm thaum teb rau email. Social engineering muab ob qho tib si syntactic thiab semantic nres txoj kev.
Ib yam yog qhov tseeb ntawm ransomware, ib hom kev tawm tsam uas ib qho me me ntawm cov lej siv dhau ntawm cov neeg siv lub khoos phis tawj lossis lub tuam txhab network thiab tom qab ntawd thov them nyiaj, hauv daim ntawv ntawm cryptocurrency, lossis cov nyiaj digital, rau kev tso tawm. lub network. Ransomware feem ntau yog tsom rau cov lag luam, tab sis nws tseem tuaj yeem tsom rau cov tib neeg yog tias cov neeg tuaj saib loj txaus.
Qee qhov kev tawm tsam cyber muaj qhov hloov pauv, uas yog lub khoos phis tawj uas tuaj yeem tso tseg cov haujlwm ntawm kev tawm tsam. Txawm li cas los xij, nws feem ntau siv cov tuam txhab kev ruaj ntseg lub sij hawm-nyob qhov twg los ntawm cov sij hawm mus rau hnub-tom qab muaj kev tawm tsam cyber nrhiav pom qhov hloov tua. Qhov ntawd yog qhov ua tau rau qee qhov kev tawm tsam kom ncav cuag cov neeg raug tsim txom ntau thaum lwm tus tsuas ncav cuag ob peb.
