Cov ntaub ntawv system yog yooj yim rau kev puas tsuaj , yuam kev thiab tsim txom vim nws yog ib hom ntawm cov ntaub ntawv digital. Nws kuj yog ntau dua yooj yim vim nws qhib rau leej twg. Hackers tuaj yeem tso tawm qhov tsis lees paub ntawm kev pabcuam (DoS) kev tawm tsam lossis nkag mus rau cov koom tes hauv tuam txhab, ua rau muaj mob hnyav. qhov system kev cuam tshuam.
Ib yam li ntawd, Qhov System Vulnerability thiab kev tsim txom yog dab tsi?
System Vulnerability thiab kev tsim txom . Thaum cov ntaub ntawv khaws cia rau hauv daim ntawv digital, lawv muaj ntau dua yooj yim tshaj thaum lawv muaj nyob rau hauv phau ntawv. Kev ruaj ntseg yog hais txog cov cai, cov txheej txheem, thiab kev ntsuas kev siv los tiv thaiv kev nkag tsis tau, hloov pauv, tub sab nyiag, lossis kev puas tsuaj rau lub cev rau cov ntaub ntawv. tshuab.
Tsis tas li ntawd, software vulnerabilities yog dab tsi? Software vulnerabilities koom nrog cov kab mob hauv software . Kab laum yog coding yuam kev uas ua rau lub kaw lus ua qhov tsis xav tau. Tag nrho software muaj kab mob ntawm ib daim ntawv lossis lwm qhov. Qee cov kab no tsim cov ntaub ntawv xau lossis nce cov cai ntawm cov neeg siv lossis tso cai txwv tsis pub nkag mus. Cov no yog kev ruaj ntseg yooj yim.
Qhov thib ob, network qhov tsis zoo yog dab tsi?
A network vulnerability yog qhov tsis muaj zog lossis qhov tsis zoo hauv software, kho vajtse, lossis cov txheej txheem koom ua ke, uas thaum muaj kev cuam tshuam los ntawm kev hem, tuaj yeem ua rau kev ruaj ntseg ua txhaum. Tsis yog lub cev network vulnerabilities feem ntau suav nrog software lossis cov ntaub ntawv.
Dab tsi yog 4 yam tseem ceeb ntawm qhov tsis zoo?
Hom Vulnerabilities - Lub cev, Social, Economic, Attitudinal Vulnerability | Kev Tshawb Fawb thiab Kev Ntsuam Xyuas.

Dab tsi yog cov ntaub ntawv yooj yim tsim los ua thiab nws ua tiav cov haujlwm no li cas?
Lub hom phiaj tseem ceeb tshaj plaws ntawm cov ntaub ntawv kaw lus yog tswj cov neeg siv cov ntaub ntawv. Qhov no suav nrog khaws cia, rov qab thiab kho cov ntaub ntawv. Qee lub tshuab ua ntaub ntawv lees txais cov ntaub ntawv khaws cia raws li cov kwj ntawm bytes uas tau sau thiab khaws cia kom zoo rau kev tshaj tawm
Dab tsi yog cov kev pabcuam muab rau txheej txheej network los ntawm cov ntaub ntawv txuas txheej?
Cov kev pabcuam tseem ceeb yog hloov cov ntaub ntawv pob ntawv los ntawm txheej txheej network ntawm lub tshuab xa mus rau txheej txheej network ntawm lub tshuab txais. Hauv kev sib txuas lus tiag tiag, cov ntaub ntawv txuas txheej xa cov khoom ntawm lub cev thiab lub cev nruab nrab
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
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
Cov txheej txheem dab tsi yog qhov yooj yim tshaj plaws rau sniffing?
Tag nrho cov ntaub ntawv raug xa raws li cov ntawv ntshiab uas tuaj yeem ua tau yooj yim sniffed. IMAP (Internet Message Access Protocol)& rho tawm; IMAP yog tib yam li SMTP hauv nws txoj haujlwm, tab sis nws muaj kev phom sij heev. Telnet & rho tawm; Telnetsends txhua yam (usernames, passwords, keystrokes) dhau lub network raws li cov ntawv ntshiab thiab yog li, nws tuaj yeem ua tau yooj yim sniffed
