Software ntawm cov ntaub ntawv tiv thaiv - lub hauv paus ntawm kev ua hauj lwm ntawm lub computer network

Software thiab kho vajtse tiv thaiv ntawm cov ntaub ntawv yog ib tug txheej ntawm kev kawm tshwj xeeb, cov kev ua ntawm uas yog raws li ib qho yooj yim mus twv, cov kev tiv thaiv ntawm cov ntaub ntawv. Cov lus qhia tseem ceeb uas siv cov cuab yeej siv los tiv thaiv cov ntaub ntawv yog raws li nram no:

- Cov ntaub ntawv tiv thaiv (ntxiv rau YOG) ntawm kev nkag tsis tau tso cai;
- LOS NTAWM LOS NTAWM COPYING;
- LOS NTAWM malware;
- kev tiv thaiv cryptographic ntawm cov ntaub ntawv;
- software tiv thaiv channel cov ntaub ntawv.

Cov ntaub ntawv tiv thaiv tawm tsam tsis tau tso cai

Txhawm rau tiv thaiv cov lus qhia los ntawm lwm tus qhov kev cuam tshuam, yuav tsum tau ua raws li kev tiv thaiv qee yam. Yog li, lub software ntaub ntawv tiv thaiv uas tau txheeb xyuas kev kawm thiab tej khoom siv, paub qhov txawv ntawm kev nkag tau mus rau cov lus qhia thiab xam kev pab, saib xyuas thiab sau cov kev txiav txim nrog lub hom phiaj kwv.

Kev lees paub thiab kev lees paub tseeb yog txhais cov lus nug uas xav tau kev nkag siab seb nws puas yog qhov nws tau hais. Txoj hau kev tshaj plaws uas yuav tsum tau txheeb xyuas yog txhawm rau siv tus password. Txawm li cas los xij, raws li kev xyaum qhia, kev tiv thaiv los ntawm kev tiv thaiv los ntawm tsis muaj txhais tau tias qhov kev tiv thaiv zoo tshaj plaws los tiv thaiv cov ntaub ntawv, vim hais tias lo lus zais muaj peev xwm tshaj tawm, saib xyuas, cuam tshuam, thiab txawm hloov tag nrho.

Tom qab ua tiav txoj kev qhia kom paub, qhov kev kawm tau txais lub sijhawm los ua haujlwm nrog cov kev pabcuam hauv lub computer system, uas yog kev tiv thaiv ntxiv ntawm cov khoom siv thiab software, thiab raws li ntawm theem kev qhia.

Cov ntaub ntawv tiv thaiv tawm tsam kev luam

Cov cuab yeej software los tiv thaiv cov ntaub ntawv tiv thaiv tsis pub luam ntawv tiv thaiv kev faib tawm cov luam ntawv tsis raug cai ntawm cov software thiab tam sim no sawv cev ntawm lub cuab yeej tsuas txhim khu kev tiv thaiv uas muaj peev xwm tiv thaiv cov cai ntawm cov neeg tsim khoom. Tus essence ntawm cov hauj lwm ntawm cov cuab yeej no yog yooj yim: qhov kev zov me nyuam yuav ua nws cov dej num nkaus xwb yog tias qee cov cim tsis tau tshaj plaws yog lees paub. Lub luag haujlwm ntawm cov khoom (xws li) yuav muab tso rau qee qhov ntawm lub computer lossis rau qhov khoom tshwj xeeb.

Cov ntaub ntawv tiv thaiv tawm tsam kev puas tsuaj

Txhua qhov kev tiv thaiv muaj lub hom phiaj tseem ceeb: nws yuav tsum tiv thaiv cov ntaub ntawv ntawm kev puas tsuaj. Vim tias cov ntaub ntawv rhuav pov tseg yuav tshwm sim vim ntau ntau cov laj thawj (kev ua tsis tau kev tso cai, software thiab kev kho teeb meem, lub computer cov kab mob, thiab lwm yam), lub koom haum ntawm kev tiv thaiv kev tiv thaiv yuav tsum yog ib qho tseem ceeb ntawm txhua tus neeg siv.

Nws tseem yog nqi khi qhov kev nyab xeeb nyiag ua los ntawm me me tab sis heev thiab siab phem cov kev pab cuam - cov kab mob, uas muaj peev xwm ntawm nws tus kheej faib thiab siv nyob rau hauv lwm tus neeg lub cov kev pab cuam thiab kis tau saum lub network. Cov creators ntawm cov kab mob muaj peev xwm ua tau ntau yam ntawm cov hom phiaj: los ntawm cov lus tso tawm tsis muaj lus ntawm lus mus rau tag nrho kev puas ntsoog ntawm cov ntaub ntawv thiab kev puas tsuaj ntawm lub system.

Cov ntaub ntawv tiv thaiv cryptographic

Cov txheej txheem cryptography tau dhau los ua ib qho ntawm cov cuab yeej tseem ceeb thiab lub peev xwm tshaj plaws uas muab kev ceev thiab cov ntaub ntawv tiv thaiv cov ntaub ntawv, uas cov cuab yeej siv tau ruaj ntseg software. Lub ntsiab tseem ceeb ntawm cryptography yog qhov kev xa los yog kev hloov ntawm cov ntaub ntawv mus rau hauv ib daim ntawv uas siv tsis tau siv tshwj xeeb encryption.

Kev tiv thaiv software ntawm cov ntaub ntawv sib kis

Lub hauv paus ntawm no kev ruaj ntseg chaw yog cov ntxaij vab tshaus - software tiv thaiv ntawm cov ntaub ntawv nyob rau hauv tes hauj lwm, lub hom phiaj uas yog kom tsis txhob muaj kev nkag tau ntawm cov neeg siv teej tug mus rau tib lub txheej ntawm network mus rau lwm lub network servers teev. Cov ntxig saib xyuas tag nrho cov lus qhia uas dhau mus ntawm ob lub tes hauj lwm. Ib qho piv txwv ntawm ib qho screen yuav pab tau ua ib qho thaiv kev ruaj ntseg (firewall), tau txhawm rau tiv thaiv cov koom hauv zos ntawm lub koom haum, uas tau nkag mus rau qhov chaw qhib (piv txwv, hauv Internet).
