Yuav Ua Li Cas Txheeb Xyuas Qhov Ua Tau Zoo ntawm Cov Ntaub Ntawv Cov Ntaub Ntawv Anti-Tampering Peev Xwm

Kev txheeb xyuas qhov ua tau zoo ntawm kev tiv thaiv -tampering peev xwm ntawm cov ntaub ntawv cov ntaub ntawv siv hauv cov cuab yeej kuaj kev laus yuav tsum muaj kev sim ua haujlwm los ntawm peb qhov: kev siv tshuab, cov txheej txheem ua haujlwm, thiab kev tswj xyuas kev tswj xyuas. Cov hauv qab no yog cov tswv yim pov thawj thiab cov txheej txheem txiav txim los xyuas kom meej qhov tseeb, traceability, thiab tsis yog -repudiation ntawm cov ntaub ntawv.

1. Kev Txheeb Xyuas Txheej Txheem Txheej Txheem: Kev ntsuas qhov ua tau zoo ntawm cov txheej txheem tiv thaiv

① Kev Ntsuam Xyuas Trail Functionality Test

Cov kauj ruam ua haujlwm:

Nkag mus rau hauv qhov system ua tus neeg teb xov tooj thiab ntxiv cov ntaub ntawv siv;

Sim hloov lossis tshem tawm cov ntaub ntawv ua tus thawj coj;

Xyuas seb lub kaw lus tsim ib lub cav ua haujlwm thiab khaws cov ntaub ntawv qub.

Cov txiaj ntsig xav tau:

Txhua qhov ntxiv, rho tawm, thiab hloov kho cov haujlwm raug kaw, suav nrog tus neeg teb xov tooj, sijhawm, IP chaw nyob, thiab cov ntsiab lus ua ntej / tom qab hloov kho;

Cov ntaub ntawv qub tsis tuaj yeem muab tshem tawm, tsuas yog kho cov lus piav qhia ntxiv tuaj yeem ntxiv;

Lub cav nws tus kheej tsis tuaj yeem cuam tshuam nrog lossis tshem tawm.

Kev Txiav Txim Siab: Ua kom tiav, thim rov qab, thiab tshawb xyuas cov ntaub ntawv tsis raug=Cov cuab yeej siv tau

② Hash Verification thiab Digital Signature Verification

Cov kauj ruam: Tau txais cov ntaub ntawv khaws cia (piv txwv li, Excel lossis PDF) rau ib hlis tshwj xeeb; Rov xam cov ntaub ntawv tus nqi hash siv lub cuab yeej (xws li SHA-256 checker); Sib piv nws nrog tus nqi hash sau thaum nws tau pib archived.

Cov txiaj ntsig xav tau: Yog tias cov ntaub ntawv tsis tau hloov kho, tus nqi hash yuav zoo ib yam nkaus; Yog tias cov ntaub ntawv tau raug cuam tshuam nrog (txawm los ntawm ib tus cim), tus nqi hash yuav txawv heev.

Cov Cai Txiav Txim: Hash tus nqi sib piv + kos npe digital pov thawj=Cov ntaub ntawv ruaj khov tiv thaiv

③ Trusted Timestamp Verification

Cov kauj ruam: Txheeb xyuas seb cov ntaub ntawv tseem ceeb suav nrog cov ntawv teev sijhawm ntseeg tau muab los ntawm lub chaw tso cai (piv txwv li, Tuam Tshoj Copyright Protection Center); Txheeb xyuas qhov siv tau ntawm lub sijhawm thiab qhov tseeb ntawm daim ntawv kos npe online.

Cov txiaj ntsig xav tau: Daim ntawv teev sijhawm ua pov thawj tias cov ntaub ntawv muaj nyob ntawm qee lub sijhawm thiab tsis tau hloov kho; Cov txiaj ntsig pov thawj yog "Pass". Kev Txiav Txim Siab: Daim ntawv teev sijhawm lees paub, tsis tas sijhawm, tsis thim rov qab=Raws li txoj cai

2. Kev Tshawb Fawb Qib Ua Haujlwm: Simulating Tampering thiab Saib Xyuas Cov Lus Teb

① Simulating Tsis tso cai hloov kev sim

Scenario 1: Tsis tso cai Account Hloov cov ntaub ntawv keeb kwm

Sim hloov cov ntaub ntawv khaws tseg los ntawm lub hli dhau los uas siv tus account tus neeg siv khoom li niaj zaus;

Cov txiaj ntsig xav tau: Lub kaw lus ceeb toom "Tsis muaj kev tso cai," kev ua haujlwm tsis lees paub.

Scenario 2: Directly Editing Local Backup Files

Rub tawm cov ntaub ntawv khaws tseg los ntawm lub khoos phis tawm offline USB, hloov kho lawv, thiab rov-upload;

Cov txiaj ntsig xav tau: Lub kaw lus tshawb pom hash mismatch, cia li ceeb toom lossis tsis lees txais nkag rau hauv cov ntaub ntawv.

Kev Txiav Txim Siab: Tag nrho cov kev ua haujlwm tsis raug tso cai raug thaiv + kev ceeb toom ntawm qhov system=Kev tswj xyuas tau zoo.

② Txheeb xyuas qhov ua raws li "Cov Txheej Txheem Kho"

Cov kauj ruam ua haujlwm:

Intentionally nkag mus rau cov ntaub ntawv tsis raug;

Xa daim ntawv "Daim Ntawv Kho Cov Ntaub Ntawv," thiab ntxiv cov ntaub ntawv kho tom qab pom zoo los ntawm tus thawj tswj hwm zoo.

Cov txiaj ntsig xav tau:

Thawj cov ntaub ntawv tsis raug yog khaws cia;

Ib qho kev kho tshiab yog ntxiv, ceeb toom vim li cas, tus neeg pom zoo, thiab lub sijhawm;

Tag nrho cov txheej txheem yog kaw rau hauv lub kaw lus.

Kev Txiav Txim Siab: Cov ntaub ntawv hloov pauv hloov tau, cov txheej txheem taug qab=Suab tswj tshuab

3. Kev Tswj Xyuas Kev Tswj Xyuas: Kev Tshawb Fawb thiab Kev Ua Raws Cai

① Execution Integrity Audit

Xyuas cov khoom:

Puas muaj lub sij hawm ntev uas tsis muaj ntaub ntawv (xws li, 3 hnub sib law liag ntawm cov ntaub ntawv dawb huv)?

Lub sijhawm ua haujlwm txhua hnub puas tshaj 24 teev?

Puas muaj cov ntaub ntawv pom zoo rau cov ntaub ntawv hloov kho?

Puas yog cov ntawv sau npe hluav taws xob thiab cov ntawv sau npe sib xws?

Kev Txiav Txim Siab: Tsis muaj cov ntaub ntawv txawv txav, kev sib raug zoo ntawm kev sib raug zoo, sib xws ntawm ob qhov chaw=Cov Ntaub Ntawv Muaj Peev Xwm

② External Review Simulation

Cov kauj ruam ua haujlwm: Simulate CNAS lossis FDA tshawb xyuas, muab cov ntaub ntawv ua tiav (cov khoom siv khoom siv → cov ntaub ntawv siv → daim ntawv pov thawj calibration → tu cov cav), thiab lees txais kev tshuaj xyuas ywj pheej.

Cov txiaj ntsig xav tau: Tus neeg tshuaj xyuas tuaj yeem txheeb xyuas qhov chaw ntawm txhua yam ntaub ntawv thiab pom tsis muaj kev cuam tshuam lossis tsis muaj kev cuam tshuam.

Kev Txiav Txim Siab: Ua kom tiav, txheeb xyuas tau, thiab tiv taus cov lus nug ntawm cov saw hlau archive=Kev npaj ua raws li qhov tsim nyog

4. Cov txheej txheem txheeb xyuas cov lus pom zoo (ntawm nrawm mus rau qhov tob)

Nco tseg: Rau siab - thaj chaw muaj kev pheej hmoo xws li kev kho mob, tsheb, thiab kev lag luam tub rog, nws raug nquahu kom ua qhov kev txheeb xyuas tob lossis thib peb - kev sim thib peb tsawg kawg ib xyoos ib zaug.
