qee qhov zoo ntawm hom no IDS yog: Lawv muaj peev xwm txheeb xyuas yog tias qhov kev tawm tsam tau ua tiav lossis tsis ua, qhov a network raws li IDS tsuas yog muab ceeb toom ntawm kev tawm tsam. A host raws lub kaw lus tuaj yeem txheeb xyuas cov tsheb khiav tawm mus nrhiav kev tawm tsam kos npe-yog li muab lawv lub peev xwm los saib xyuas cov tsheb khiav encrypted.
Yog li, lub network raws li IDS txawv li cas ntawm tus tswv tsev raws li IDS?
Dab tsi yog qhov txawv nruab nrab a network raws li IDS ( intrusion nrhiav system) thiab a host based IDS ? Host raws IDSes siv cov sensors nrog NICs ( network interface cards) teem rau promiscuous hom los saib xyuas network kev ua si. Network raws IDSes tsom mus rau kev ua haujlwm ntawm tus neeg siv khoom lossis lub tshuab server uas lawv tau teeb tsa.
Ib yam li ntawd, qhov sib txawv ntawm tus tswv tsev raws li thiab network raws li firewalls yog dab tsi? Thaum Network Based Firewall lim cov tsheb khiav mus los ntawm Is Taws Nem kom ruaj ntseg LAN thiab rov ua dua, a host raws firewall yog ib daim ntawv thov software lossis suite ntawm cov ntawv thov ntsia ntawm ib lub computer thiab muab kev tiv thaiv rau cov tus tswv tsev . Txawm li cas los xij thaum nws los loj dua tes hauj lwm , Host raws Firewalls tsis txaus.
Tib neeg kuj nug, dab tsi yog lub network raws li kev nkag mus nrhiav qhov system?
A network - Raws li intrusion detection system (NIDS) yog siv los saib xyuas thiab tshuaj xyuas network tsheb tiv thaiv a qhov system los ntawm network - raws kev hem. NIDS nyeem tag nrho cov pob ntawv sab hauv thiab tshawb nrhiav cov qauv tsis txaus ntseeg.
Yuav ua li cas host based intrusion detection system ua haujlwm?
A tus tswv tsev - raws li IDS yog ib intrusion detection system uas saib xyuas lub computer infrastructure uas nws tau teeb tsa, txheeb xyuas kev khiav tsheb thiab nkag mus rau tus cwj pwm phem. Ib qho HIDS muab kev pom tob rau koj txog qhov tshwm sim ntawm koj qhov kev ruaj ntseg tseem ceeb tshuab.

Dab tsi yog qhov txawv ntawm kev tswj qhov xwm txheej thiab kev tswj xyuas qhov xwm txheej loj?
Yog li MI yog hais txog kev lees paub tias qhov xwm txheej ib txwm muaj thiab Kev Tswj Xyuas Teeb Meem yuav tsis txiav nws. Ib qho xwm txheej loj yog kev tshaj tawm ntawm lub xeev xwm txheej ceev. Ib qho xwm txheej loj yog nruab nrab ntawm qhov xwm txheej ib txwm muaj thiab kev puas tsuaj (qhov twg IT Service Continuity Management txheej txheem pib)
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Dab tsi yog lub tswv yim los tswj cov kev txwv ntawm kev nkag mus ntawm cov peev txheej thaum ntau cov xov raug tua hauv Redis?
xauv Khaws qhov no hauv kev txiav txim siab, Redis ua li cas nrog kev sib raug zoo? Ib qho kev pabcuam ib leeg tuaj yeem muab tau sib npaug ntawm I / O qib los ntawm kev siv I / O (de) multiplexing mechanism thiab lub voj xwm txheej (uas yog dab tsi Redis ua ).
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Dab tsi yog qhov txawv ntawm kev nkag mus tau thiab kev tsim qauv?
Qhov txawv ntawm Inclusive Design thiab Accessibility yog dab tsi? Thaum suav nrog kev tsim qauv txiav txim siab txij li thaum pib yuav ua li cas qee yam yuav yooj yim pab tau thiab txaus siab rau ntau tus neeg raws li qhov ua tau, kev nkag mus tau ib txwm txhais tau tias txiav txim siab tshwj xeeb rau cov neeg tsis taus
