Txhawm rau teeb tsa network encryption:
- Ntawm lub server computer, pib Oracle Net Manager.
- Los ntawm Oracle Net Configuration navigation tree, nthuav Local, thiab tom qab ntawd xaiv Profile.
- Los ntawm cov npe, xaiv Oracle Advanced Security.
- Hauv qab Oracle Advanced Security, xaiv lub Encryption tab.
- Nkag mus rau cov chaw hauv qab no:
Kuj nug, kuv tuaj yeem qhia tau li cas yog Oracle database encrypted?
1) Nkag mus rau SQLPlus li sys li sysdba, 2) ua cov lus hauv qab no: SELECT * NTAWM DBA_ENCRYPTED_COLUMNS; Qhov no yuav rov qab cov ntaub ntawv rau txhua kab hauv lub database uas tau encrypted nrog rau lub tablename, tus tswv, columnname thiab encryption algorithm.
Tsis tas li, ODBC kev sib txuas puas ruaj ntseg? ODBC tsis encrypt koj cov ntaub ntawv rau kis, yog li muab kev ruaj ntseg rau lub database tsheb koj yuav tsum tau tunnel lub ODBC tsheb khiav los ntawm kev siv network ruaj ntseg Plhaub, ruaj ntseg Sockets Layer, Point-to-Point Tunneling Protocol/Layer 2 Tunneling Protocol lossis IPSec.
Ib yam li ntawd, koj tuaj yeem nug, yog Chaw nres nkoj 1521 Ruaj Ntseg?
Chaw nres nkoj 1521 yog tus neeg siv khoom sib txuas chaw nres nkoj Txawm li cas los xij, koj tuaj yeem teeb tsa lwm TCP chaw nres nkoj ntawm Oracle configuration thiab tswj cov cuab yeej. Lub neej ntawd SSL chaw nres nkoj rau ruaj ntseg Oracle cov neeg siv kev sib txuas rau cov ntaub ntawv los ntawm Oracle's SQL * Net raws tu qauv. Qhib qhov no chaw nres nkoj yog koj xav tau ruaj ntseg kev sib txuas.
TCPS raws tu qauv yog dab tsi?
Oracle TCPS raws tu qauv rau repositories. Xa tawm tswv yim. Xaiv los siv cov TCPS (TCP nrog SSL) raws tu qauv Thaum koj teeb tsa koj qhov chaw cia Oracle hauv Central Management Console (CMC). TCPS raws tu qauv yog ib qho kev xaiv uas Cov Kev Pabcuam Cov Ntaub Ntawv txhawb nqa rau koj qhov chaw cia Oracle.

Kev sib cav sib ceg sib txawv li cas ntawm kev sib cav tsis zoo?
Txhua qhov kev sib cav tsis zoo siv txoj cai invalid inference. Yog tias qhov kev sib cav tsis zoo koj paub tias nws tsis siv. Kev siv tau txhais tau tias tsis muaj kev txhais lus qhov twg qhov chaw muaj tseeb thiab qhov kev txiav txim siab tuaj yeem tsis tseeb ib txhij. Yog tias qhov kev sib cav ua txhaum koj tuaj yeem tsis quav ntsej nws thiab sim nkag siab lub ntsiab lus tseem
Dab tsi yog tag nrho cov kab kev sib txuas lus uas xav tau rau kev sib txuas tag nrho rau taw tes network ntawm tsib lub khoos phis tawj rau lub khoos phis tawj?
Tus naj npawb ntawm cov kab sib txuas lus uas yuav tsum tau muaj rau kev sib txuas tag nrho ntawm qhov taw tes rau-taw tes ntawm yim lub khoos phis tawj yog nees nkaum yim. Ib tug tag nrho txuas cuaj lub computer network yuav tsum tau peb caug rau kab. Ib tug tag nrho txuas kaum lub computer network yuav tsum tau plaub caug tsib kab
Dab tsi yog qhov sib txawv ntawm kev sib txuas lus taw qhia thiab kev sib txuas tsis raug cai?
Qhov txawv: Kev sib txuas lus taw qhia thiab kev sib txuas tsis muaj kev sib txuas Kev sib txuas lus taw qhia kev sib txuas ua rau muaj kev sib txuas thiab xyuas seb cov lus puas tau txais lossis tsis tau thiab xa rov qab yog tias muaj qhov yuam kev tshwm sim, thaum qhov kev pabcuam tsis sib txuas tsis tau lees tias xa xov
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 sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
