Koj yuav tsum paub dab tsi txog kev sib tawm tsam thiab tiv thaiv lawv
Cov teeb meem ntawm Cyber yuav tuaj yeem siv ntau yam ntaub ntawv los ntawm kev tiv thaiv cov ntaub ntawv ntawm tus kheej kom tswj tau cov computers thiab xav tau tus nqe txhiv - feem ntau them nyiaj hauv cryptocurrency - kom tso tawm qhov kev tswj no. Thiab yog vim li cas cov kev tawm tsam kis tau sai heev yog vim lawv muaj peev xwm ua rau hnov.
Yuav ua li cas Cyber Attacks
Kev nkag siab txog kev ua phem rau hauv xov tooj thiab cyber tawm tsam tsuas yog ib feem ntawm cov ntaub ntawv xav tau los tiv thaiv koj tus kheej. Koj yuav tsum paub zoo tias txoj hauv kev cyber attack tuaj. Feem ntau cov kev tawm tsam yog kev sib txuam nrog kev sib txuas lus los siv, los ua cov lus sib sim yooj yim, sim ua kom pauv tus neeg siv lub computer tus cwj pwm los ntawm kev siv lub tshuab tactics hauv computer.
Piv txwv, phishing e-mails hais hauv qab no. Ob hom kev thev naus laus zis thiab ib hom cyber tua software - kab mob los yog kab nab npawb - siv los ntxias koj mus muab cov ntaub ntawv los yog downloading ib cov ntaub ntawv uas muaj cai code hauv koj lub computer mus nyiag koj cov ntaub ntawv. Ib qho ntawm cov lej no yuav raug piav raws li cov lus sib cav sib ceg.
Cas Cyber Attacks zoo li
Yog li, qhov kev sibtham sib txuas lus zoo li cas? Nws yog ib qho lus uas tshwm los ntawm koj lub tsev txhab nyiaj los yog credit card tuam txhab. Nws zoo li ceev nrooj thiab muaj qhov txuas mus nyem. Txawm li cas los xij, yog tias koj saib zoo rau hauv email, koj tuaj yeem nrhiav cov ntsiab lus uas nws tsis yog qhov tseeb.
Hover koj tus pointer hla qhov txuas ( tab sis tsis txhob nias nws ), tom qab ntawd saib qhov chaw nyob hauv web uas qhia txog saum toj qhov txuas lossis hauv qab ntawm kaum sab xis ntawm koj npo. Qhov txuas txuas puas yog tiag tiag, los yog nws puas muaj cov ncauj lus, los yog cov npe uas tsis cuam tshuam nrog koj lub txhab nyiaj? Tus email kuj tseem muaj typos lossis zoo li nws tau sau los ntawm ib tus neeg uas hais lus Askiv ua hom lus thib ob.
Lwm txoj kev uas cyber tawm tsam yog thaum koj download tau ib daim ntawv uas muaj lub siab phem daim cai, feem ntau yog ib tug cab los yog ib tug Trojan nees. Qhov no tshwm sim los ntawm kev xa cov ntaub ntawv e-mail, tab sis nws kuj tuaj yeem tshwm sim thaum koj download apps, videos, thiab music files online. Muaj ntau cov ntaub ntawv sib qhia cov ntaub ntawv uas koj tuaj yeem luam tau cov phau ntawv, tsos, TV yeeb yaj duab, suab paj nruag, thiab kev ua si dawb, feem ntau yog cov neeg txheeb ze. Lawv yuav xa cov nplooj ntawv phav phav tuaj yeem xa tuaj rau koj, tab sis thaum koj qhib lub file, koj lub computer tau raug tus kab mob thiab tus kab mob virus, kab mob, lossis Trojan nees pib kis.
Kev mus saib cov kabmob web sites yog ib txoj hauv kev los khaws txhua yam kev cyber kev hem. Thiab qhov teeb meem nrog rau cov kab mob kis tau tus kab mob yog qhov lawv feem ntau zoo ib yam li slick thiab kev raws li cov vev xaib uas siv tau. Koj tsis txawm txhawj xeeb tias koj lub computer raug mob thaum koj das lub vev xaib los yog ua yuav khoom.
To taub Cyber Threats
Ib qho tseem ceeb tshaj plaws ntawm cov neeg cyber tawm tsam yog tib neeg tus cwj pwm. Txawm tias qhov tseeb, kev ruaj siab tshaj plaws yuav tiv thaiv tsis tau koj yog tias koj qhib lub qhov rooj thiab cia tus neeg ua txhaum ntawd. Tias yog vim li cas nws tseem ceeb heev kom paub tias cov kev xav cyber yog dab tsi, yuav ua li cas thiaj pom tias muaj kev sib ntaus, thiab tiv thaiv koj tus kheej.
Kev sib ntxeeb ntawm Cyber tuaj yeem raug faib ua ob lub thoob: kev tawm tsam thiab kev tawm tsam.
Syntactic Cyber Attacks
Syntactic tawm tsam yog ntau hom kev siab phem software uas tua koj lub computer los ntawm ntau txoj kev.
Cov feem ntau cov software siv hauv syntactic tawm tsam xws li:
- Viruses: Tus kab mob yog ib qho software uas tuaj yeem xa tau nws tus kheej mus rau lwm cov ntaub ntawv lossis qhov kev zov me nyuam los muab tsim tawm. Hom software no feem ntau pom muaj nyob rau hauv cov ntaub ntawv downloads thiab email attachments. Thaum koj download tau daim ntawv txuas los yog pib lub download, tus kab mob yog qhib kom ua, nws replicates, thiab xa nws tus kheej rau txhua tus neeg hauv koj cov ntaub ntawv tiv tauj.
- Worms: Cov nab kuab tsis xav tau lwm cov ntaub ntawv los yog qhov kev zov me nyuam kom rov tsim thiab kis tau. Cov khoom me me ntawm cov software tseem muaj ntau dua thiab tau sau thiab xa cov ntaub ntawv mus rau ib qhov chaw uas siv cov lus qhia txog lub network nws nyob rau. Tus kab mob cab ua rau lub computer thaum nws tau xa ntawm lwm daim software rau ntawm lub network. Qhov no yog vim li cas cov lag luam feem ntau txom nyem loj heev cyber tawm tsam, vim hais tias cov cua nab kis ntawm lub network.
- Trojan Nees: Zoo li Trojan nees siv los ntawm cov Greeks hauv Tsovrog Thoj Tsov Rog, ib tug sib tham hauv xov tooj trojan zoo li ib yam dab tsi innocuous, tab sis yog tiag zais ib yam nefarious. Ib tug trojan nees yuav yog ib qho email uas zoo li nws los ntawm lub tuam txhab cia siab, thaum qhov tseeb, nws raug xa los ntawm criminals los yog cov neeg phem.
Semantic Cyber Attacks
Semantic tawm tsam ntau ntxiv txog kev pauv qhov kev xav lossis tus cwj pwm ntawm tus neeg lossis lub koom haum uas raug tawm tsam. Muaj tsawg dua qhov ua kom pom tseeb ntawm qhov software muab kev koom tes.
Piv txwv, phom tua yog ib hom kev sib sim siab. Phishing tshwm sim thaum ib tus neeg ua lag luam phem xa tawm emails sim sau cov lus qhia los ntawm tus neeg tau txais kev pab. Tus e-mail feem ntau zoo nkaus li yog los ntawm lub lag luam uas koj ua lag luam thiab nws hais tias koj tus account tau nyom lawm. Koj tau raug qhia kom nias ntawm qhov txuas thiab muab qee cov ntaub ntawv los xyuas txog koj tus account.
Phom tuaj yeem yuav raug tua siv software, thiab tej zaum yuav muaj xws li cua nab los yog kab mob, tiam sis yog qhov tseem ceeb ntawm cov kev tawm tsam no yog kev tsim vaj tse (engineering) - kev sim hloov tus cwj pwm thaum nws teb rau emails. Social engineering muab cov lus sib dhos los sib xyaw ua ke thiab cov kev sib txuas ua ke.
Qhov no yog qhov tseeb ntawm ransomware , ib hom kev sib tawm tsam qhov me me ntawm cov cai siv lub tshuab computer (lossis lub lag luam network) thiab ces xav kom them nqi, hauv daim ntawv cryptocurrency, lossis cov nyiaj digital, rau kev tso tawm ntawm lub network. Ransomware feem ntau yog targeted ntawm cov lag luam, tab sis kuj tuaj yeem tsom rau cov tib neeg yog hais tias cov neeg tuaj saib yog loj txaus.
Qee qhov kev sib thuam ntawm cyber muaj kev tua tua, uas yog lub tshuab computer uas yuav txwv tsis tau qhov kev ua si ntawm kev tawm tsam. Txawm li cas los xij, nws yuav siv sij hawm ruaj ntseg tuam txhab - txhua qhov chaw los ntawm cov xuab moos mus rau ib hnub - tom qab ib tug cyber nres nrhiav tau kom pom qhov tua tau tua. Qhov ntawd yog qhov ua tau rau qee cov kev tawm tsam mus cuag ntau tus neeg raug tsim txom thaum lwm tus tsuas yog mus txog ob peb.
Yuav Tiv Thaiv Koj Tus Kheej Li Cas Tawm Tsam Ze
Nws zoo nkaus li zoo li ib qho kev sib ntaus sib tua loj heev txhua hnub hauv Tebchaws Meskas Yog li, koj yuav tiv thaiv koj tus kheej li cas? Koj yuav tsis ntseeg nws, tiamsis yog ib qho ntawm qhov chaw muaj kev ruaj ntseg thiab muaj kev voj voog, muaj qee txoj hauv kev los xyuas kom meej tias koj tsis raug tsim txom rau ib qho kev sib ntaus sib tua hauv xov tooj:
- Cia koj cov secrets, zais cia. Tsis txhob qhia tawm koj cov ntaub ntawv hauv Internet tshwj tsis yog tias koj paub meej tias koj tab tom ua haujlwm nrog lub web site zoo.

- Khaws koj lub cev kom txog hnub. Hackers nyob rau cov computers uas yog outdated thiab cov uas tsis tau muaj kev ruaj ntseg tshiab lossis thaj ua haujlwm nyob rau hauv ib lub sijhawm ntev. Lawv tau kawm txog kev nkag mus rau hauv koj lub computer, thiab yog tias koj tsis tau ntsia tshiab lossis thaj chaw ruaj ntseg, ces koj qhib lub qhov rooj thiab caw lawv tuaj. Yog tias koj tuaj yeem cia cov xov xwm tshiab hauv koj lub computer, ua li ntawd. Yog hais tias tsis yog, ces ua kom nws xyaum ua kiag li tshiab thiab thaj ua rau thaj chaw kom sai li sai tau yog tias koj tau txais ntawv ceeb toom lawv muaj. Ua kom koj lub cev mus txog hnub tim yog ib qho ntawm koj cov riam phom zoo tshaj plaws rau hauv kev cyber tawm tsam.
