Cov ntaub ntawv khaws cia . Cov ntaub ntawv khaws tseg yog tus txheej txheem ntawm kev sib sau thiab ntsuas cov ntaub ntawv ntawm kev sib txawv ntawm qhov kev txaus siab, nyob rau hauv ib qho kev tsim qauv tsim uas ua rau ib qho lus teb tau hais tseg kev tshawb fawb cov lus nug, sim hypotheses, thiab ntsuas cov txiaj ntsig.
Ntxiv mus, dab tsi yog hom kev sau cov ntaub ntawv hauv kev tshawb fawb?
Cov ntaub ntawv tej zaum yuav muab faib ua plaub lub ntsiab hom raws li txoj kev rau sau : kev soj ntsuam, simulation, thiab muab tau los. Cov hom ntawm cov ntaub ntawv tshawb fawb koj sau tuaj yeem cuam tshuam rau txoj kev koj tswj qhov ntawd cov ntaub ntawv.
Dhau li saum toj no, dab tsi yog qhov tsim cov ntaub ntawv hauv kev tshawb fawb? Cov ntaub ntawv tiam hais txog txoj kev xav thiab txoj kev siv los ntawm cov kws tshawb fawb tsim cov ntaub ntawv los ntawm tus qauv cov ntaub ntawv qhov chaw nyob rau hauv qualitative kawm . Cov ntaub ntawv cov peev txheej suav nrog tib neeg koom nrog, cov ntaub ntawv, cov koom haum, xov xwm hluav taws xob, thiab cov xwm txheej (rau npe rau qee qhov piv txwv).
vim li cas kev sau cov ntaub ntawv tseem ceeb hauv kev tshawb fawb?
Nws yog los ntawm sau cov ntaub ntawv tias kev lag luam lossis kev tswj hwm muaj cov ntaub ntawv zoo uas lawv xav tau los txiav txim siab los ntawm kev tshuaj xyuas ntxiv, kawm , thiab kev tshawb fawb . Cov ntaub ntawv khaws tseg es tsis txhob tso cai rau lawv nyob rau sab saum toj feem ntau, muab cov lus teb rau cov teeb meem, thiab tshuaj xyuas cov kev pom tshiab kom muaj txiaj ntsig zoo.
Dab tsi yog 5 txoj hauv kev los sau cov ntaub ntawv?
Cov txheej txheem sau cov ntaub ntawv zoo
- Open-Ended Surveys thiab Questionnaires. Rov qab mus rau kaw-endedare qhib-kawg kev tshawb fawb thiab cov lus nug.
- 1-on-1 Interviews. Kev xam phaj ib-rau-ib (los yog ntsej muag) yog ib qho ntawm ntau hom kev sau cov ntaub ntawv kev tshawb fawb tsis zoo.
- Focus pawg.
- Kev soj ntsuam ncaj qha.

Dab tsi yog tus lej ncaj qha uas yuav tsum raug tshem tawm ntawm cov ntaub ntawv tshawb fawb kom ua raws li kev siv cov ntaub ntawv txwv?
Cov ntaub ntawv qhia ncaj qha hauv qab no yuav tsum raug tshem tawm rau PHI kom tsim nyog raws li cov ntaub ntawv txwv: (1) Cov npe; (2) Cov ntaub ntawv chaw nyob xa ntawv, tsis yog lub nroog lossis nroog, xeev, thiab ZIP code; (3) xov tooj; (4) fax xov tooj; (5) email chaw nyob; (6) social security naj npawb; (7) cov ntaub ntawv kho mob; (8) kev npaj kho mob
Cov ntaub ntawv twg los ua ntej hauv qhov kev txiav txim ntawm kev hloov pauv thaum ua qhov kev tshawb nrhiav forensic?
IETF thiab Order of Volatility Cov ntaub ntawv no piav qhia tias kev sau cov ntaub ntawv pov thawj yuav tsum pib nrog cov khoom tsis hloov pauv thiab xaus nrog yam tsawg kawg nkaus. Yog li, raws li IETF, Order of Volatility yog raws li nram no: Sau npe, Cache. Routing Table, ARP Cache, Txheej Txheem Txheej Txheem, Kernel Statistics
Dab tsi ntawm cov hauv qab no yog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv hauv kev tshawb fawb zoo?
Cov txheej txheem kev txheeb xyuas cov ntaub ntawv feem ntau siv yog: Kev tsom xam cov ntsiab lus: Qhov no yog ib txoj hauv kev zoo tshaj plaws los tshuaj xyuas cov ntaub ntawv zoo. Kev txheeb xyuas cov lus piav qhia: Txoj kev no yog siv los txheeb xyuas cov ntsiab lus los ntawm ntau qhov chaw, xws li kev xam phaj ntawm cov neeg teb, kev soj ntsuam los ntawm thaj chaw, lossis kev tshawb fawb
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
