Cov khoos phib tawj ntxiv ntawm kev ua kom pom nqaim, muab kev nthuav dav ntawm kev ua haujlwm ntawm kev ua haujlwm thiab kev hloov pauv ntawm qee qhov chaw, hu ua kev siv hluav taws xob.
Lub hom phiaj ntawm kev siv hluav taws xob muaj ntau yam sib txawv. Cov kev pabcuam pabcuam tiv thaiv lub koos pij tawj cov kab mob, tswj qhov tsis raug ntawm cov khoom siv sib txuas thiab cov khoom siv sab nraud, thiab ua lwm cov haujlwm tseem ceeb uas tsis tuaj yeem daws los ntawm cov cuab yeej ua haujlwm txheem.
Cov kev siv hluav taws xob pab tiv thaiv cov ntaub ntawv cov ntaub ntawv ntawm tus kheej cov ntsiab lus los ntawm encryption ntawm sib txawv ntawm qhov nyuaj ntawm kev nyuaj, nrog rau kev teeb tsa tus password nkag mus rau cov ntawv. Nov yog ib qho tseem ceeb uas tso cai rau koj los tiv thaiv cov ntaub ntawv ntiag tug ntawm lwm tus neeg cuam tshuam, puas tsuaj thiab tub sab.
Qhov kev tawm tsam no feem ntau ua rau daim ntawv pov thawj cov ntawv pov thawj, cov lej, tus lej txuas lus, tsev neeg lossis cov ntaub ntawv xov xwm lag luam (duab, yeeb yaj duab, nthuav tawm), cov software uas muaj lai xees, email programs, kev siv lub kaw lus.
Cov cuab yeej siv soj ntsuam cov kev ua tau zoo ntawm ntau cov kev pabcuam hauv computer, piv txwv li, processor, disk thiab nco daim npav nyeem ntawv, daim npav video, modem, RAM thiab lub cev nco, thiab lwm yam. Tsis tas li ntawd, cov kev siv hluav taws xob tas li ua qhov kev sim ntawm cov khoom siv sab hauv thiab cov khoom siv thiab lub teeb liab thaum pom cov teeb meem, lawv tseem ua qhov yuav tsum tau txhim kho lossis hloov software thiab txuas ntxiv (piv txwv, lub tshuab luam ntawv cartridge).
Lub chaw siv hluav taws xob rov qab cov ntaub ntawv ploj uas tau muab tshem tawm hauv cov khoom ntim khoom pov tseg. Cov kev pab cuam tib yam yuav pab tshem tawm cov ntaub ntawv hauv koj lub computer mus tas li, yog tias xav tau.
Muaj qee yam kev siv uas hu ua tweakers uas tau siv los nyem qhov chaw teeb tsa ua haujlwm. Cov kev pab cuam no daws tau ntau yam teeb meem, piv txwv li, rov kho qhov interface rau ib tus neeg siv, txhim kho lub kaw lus.
Tseem muaj kev siv "tsis zoo" uas tuaj yeem cuam tshuam lub computer lawv tus kheej. Cov hacker kev tsim tawm suav nrog cov tsim tsim (lawv txuas ntxiv tsim kab mob), cua nab, "kev tso dag" cov kev pab cuam uas muab cov ntaub ntawv tsis raug rau cov neeg siv txog kev ua haujlwm ntawm lub koos pij tawj, thiab lwm yam.
Feem ntau ntawm cov kev siv tau muaj cov xwm txheej ntawm cov software dawb, qee zaum lawv tau thov thoob plaws ntiaj teb nrog ntau cov haujlwm.
