Dab tsi hom algorithms yuav tsum tau xa thiab txais los pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus ? Kev piav qhia: Symmetrical siv algorithms tib yam tus yuam sij , a tus yuam sij zais cia , los encrypt thiab decrypt cov ntaub ntawv. Qhov no tus yuam sij yuav tsum tau sib koom ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim.
Tsis tas li ntawd, ob lub algorithms twg tuaj yeem yog ib feem ntawm IPsec txoj cai los muab kev encryption thiab hashing los tiv thaiv kev nthuav dav?
Cov IPsec lub moj khaum siv ntau yam kev cai thiab algorithms rau muab cov ntaub ntawv tsis pub lwm tus paub, cov ntaub ntawv ncaj ncees, kev lees paub, thiab kev sib pauv hloov pauv. Ob algorithms uas ua tau yuav siv nyob rau hauv ib IPsec txoj cai rau tiv thaiv kev nthuav dav yog AES, uas yog ib qho encryption raws tu qauv, thiab SHA, uas yog a hashing algorithm.
Tsis tas li ntawd, cov algorithm twg tuaj yeem ua kom cov ntaub ntawv tsis pub lwm tus paub? Txawm tias classical encryption algorithms ua kom cov ntaub ntawv tsis pub lwm tus paub , lawv hmoov tsis zoo tiv thaiv huab los ntawm kev khiav hauj lwm dhau encrypted cov ntaub ntawv . Txoj kev pom tseeb ua tau yuav encrypt tag nrho cov ntaub ntawv nrog kev ruaj ntseg encryption algorithm xws li AES thiab khaws cia rau hauv huab.
Hais txog qhov no, qhov txawv ntawm ASA IPv4 ACLs thiab IOS ipv4 ACLS yog dab tsi?
ASA ACLs yeej ib txwm muaj npe, whereas IOS ACLs ib txwm suav. Ntau ASA ACLs tuaj yeem siv rau ntawm qhov interface hauv ingress kev taw qhia, whereas tsuas yog ib IOS ACL tuaj yeem siv tau. ASA ACLs tsis muaj qhov tsis lees paub qhov kawg, qhov twg IOS ACLs ua.
Cov kev pabcuam lossis cov txheej txheem twg uas Secure Copy Protocol vam khom kom ntseeg tau tias kev hloov pauv kev nyab xeeb yog los ntawm cov neeg siv tau tso cai?
Secure Copy Protocol ( SCP ) yog siv rau ruaj ntseg luam IOS duab thiab configuration ntaub ntawv rau a SCP server. Txhawm rau ua qhov no, SCP yuav siv SSH kev sib txuas los ntawm cov neeg siv authenticated los ntawm AAA.

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 qhov txawv ntawm cov neeg siv kev paub thiab kev paub ntawm cov neeg siv khoom?
User Experience (UX) cuam tshuam nrog tib neeg cuam tshuam nrog koj cov khoom thiab cov kev paub uas lawv tau txais los ntawm kev sib cuam tshuam. Customer Experience (CX), incontrast, encompasses tag nrho cov kev sib cuam tshuam ib tug neeg muaj nrog koj hom
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Vim li cas nws tseem ceeb kom khaws cov ntaub ntawv tsis pub lwm tus paub hauv kev noj qab haus huv thiab kev saib xyuas kev noj qab haus huv?
Ib qho tseem ceeb tshaj plaws ntawm kev ceev ntiag tug yog tias nws pab tsim thiab txhim kho kev ntseeg siab. Nws muaj peev xwm tso cai rau cov ntaub ntawv pub dawb ntawm cov neeg siv khoom thiab cov neeg ua haujlwm thiab lees paub tias tus neeg siv khoom lub neej thiab txhua yam teeb meem thiab teeb meem uas lawv muaj rau lawv
Cov kev pabcuam lossis cov txheej txheem twg uas Secure Copy Protocol vam khom kom ntseeg tau tias kev hloov pauv kev nyab xeeb yog los ntawm cov neeg siv tau tso cai?
Cov kev pabcuam lossis cov txheej txheem twg uas Secure Copy Protocol vam khom kom ntseeg tau tias kev hloov pauv kev nyab xeeb yog los ntawm cov neeg siv tau tso cai? Secure Copy Protocol (SCP) yog siv los luam cov duab IOS kom ruaj ntseg thiab teeb tsa cov ntaub ntawv mus rau SCP server. Txhawm rau ua qhov no, SCP yuav siv SSH kev sib txuas los ntawm cov neeg siv uas tau lees paub los ntawm AAA
