Nyob zoo, Kev sib txheeb yog tus txheej txheem los taug qab kev sib raug zoo ntawm qhov xwm txheej raws li tau hais tseg hauv txoj cai. Thaum muaj cov xwm txheej tshwm sim uas phim cov xwm txheej tau teev tseg hauv txoj cai, cov xwm txheej uas ua rau muaj kev sib ntsib raug hu kev sib raug zoo xwm txheej.
Ib yam li ib tug yuav nug, dab tsi yog kev sib raug zoo thiab kev sib sau ua ke hauv ArcSight?
Kev sib txheeb yog tus txheej txheem los taug qab qhov kev sib raug zoo ntawm qhov xwm txheej raws li tau hais tseg. Thaum kev sib sau ua ke yog txheej txheem los sau cov xwm txheej zoo sib xws.
Tsis tas li, dab tsi yog qhov normalization hauv ArcSight? normalization yog tus txheej txheem ntawm kev noj qhov tseem ceeb uas muaj nyob rau hauv ib qho kev tshwm sim thiab qhia lawv mus rau hauv tus qauv schema. Cov ArcSight CEF hom ntawv muaj 400+ teb nyob rau hauv nws cov schema uas cov ntaub ntawv teev cia yuav mapped rau.
Dab tsi yog kev sib raug zoo hauv Siem?
Ntau yam khoom siv hauv koj lub network yuav tsum tau tsim cov ntawv teev kev tshwm sim uas tau pub rau koj SIEM qhov system. A SIEM correlation txoj cai qhia koj SIEM kab ke uas cov xwm txheej ntawm cov xwm txheej tuaj yeem yog qhov qhia txog kev tsis txaus ntseeg uas yuav qhia txog kev ruaj ntseg tsis muaj zog lossis kev tawm tsam cyber.
Dab tsi yog aggregation hauv Siem?
Kev sib sau ua ke yog cov txheej txheem ntawm kev txav cov ntaub ntawv thiab cov ntaub ntawv teev tseg los ntawm qhov chaw sib txawv rau hauv ib qho chaw khaws cia. Cov txheej txheem ntawm kev sib sau ua ke - suav nrog cov xwm txheej sib txawv no pub rau hauv ib qho chaw khaws cia - yog qhov tseem ceeb rau Kev Tswj Xyuas Kev Lag Luam thiab feem ntau SIEM platforms.

Vim li cas kev sib raug zoo algebra siv nyob rau hauv kev sib raug zoo database tswj?
RELATIONAL ALGEBRA yog ib hom lus nug uas siv dav heev. Nws sau cov xwm txheej ntawm kev sib raug zoo raws li kev tawm tswv yim thiab muab qhov tshwm sim ntawm kev sib raug zoo raws li cov zis. Nws siv ntau yam haujlwm los ua qhov haujlwm no. Relational algebra operations yog ua recursively ntawm kev sib raug zoo
Dab tsi yog kev sib tshuam hauv kev sib raug zoo algebra?
INTERSECTION kev khiav hauj lwm nyob rau hauv RELATIONAL ALGEBRA. Kev sib tshuam ntawm teeb A thiab B = A ∩ B = {1, 6} Cov ntsiab lus uas muaj nyob rau hauv ob qho tib si A thiab B yuav tsuas muaj nyob rau hauv lub teeb tau los ntawm kev sib tshuam ntawm A thiab B
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog qhov txawv ntawm kev sib raug zoo thiab tsis muaj kev sib raug zoo databases?
Qhov sib txawv loj ntawm lawv yog li cas lawv tuav cov ntaub ntawv. Relational databases are structured.Non-relational databases are document-oriented. Qhov no hu ua cov ntaub ntawv hom cia tso cai ntau 'qeb' ntawm cov ntaub ntawv khaws cia hauv ib qho kev tsim lossis Cov Ntaub Ntawv
Dab tsi yog qee qhov tsis zoo ntawm lub sijhawm stamping txoj hauv kev rau kev tswj hwm kev sib raug zoo?
Qhov tsis zoo ntawm lub sij hawm stamping mus kom ze yog tias txhua tus nqi khaws cia hauv cov ntaub ntawv yuav tsum muaj ob lub sij hawm thwj ntxiv: ib qho rau lub sijhawm kawg ntawm daim teb tau nyeem thiab ib qho rau qhov hloov tshiab kawg. Lub sij hawm stamping yog li ua rau kom nco xav tau thiab cov ntaub ntawv ua haujlwm nyiaj siv ua haujlwm
