Nws yog tus txheej txheem txhawm rau txheeb xyuas qhov tsis zoo ntawm kev nyab xeeb hauv daim ntawv thov los ntawm kev ntsuas lub kaw lus lossis kev sib txuas nrog ntau yam kev phem. Thaum pom qhov tsis yooj yim, nws yog siv los siv lub system kom nkag mus rau cov ntaub ntawv rhiab heev.
Tsuas yog li ntawd, qhov kev ntsuam xyuas nkag mus rau qhov twg?
Kev xeem nkag , kuj hu cwj mem xeem los yog ethical hacking, yog kev xyaum ntawm kuaj lub computer system, network lossis web daim ntawv thov mus nrhiav kev ruaj ntseg vulnerabilities uas tus attacker yuav exploit. Lub hom phiaj tseem ceeb ntawm nkag mus kuaj yog txheeb xyuas kev ruaj ntseg tsis muaj zog.
Ib sab saum toj no, qhov kev ntsuam xyuas nkag nrog piv txwv yog dab tsi? Piv txwv ntawm Kev xeem nkag Cov cuab yeej NMap- Cov cuab yeej no yog siv los ua qhov chaw nres nkoj scanning, OS txheeb xyuas, taug qab txoj hauv kev thiab rau Vulnerability scanning. Nessus- Qhov no yog ib txwm siv network-based vulnerabilities cuab tam. Pass-The-Hash - Cov cuab yeej no feem ntau yog siv rau kev tawg lo lus zais.
Ib tug kuj yuav nug, dab tsi yog cov kauj ruam hauv kev xeem nkag?
7 theem kev xeem nkag yog: Kev nqis tes ua ua ntej, kev tshawb nrhiav, kev tsim qauv kev hem thawj thiab kev txheeb xyuas qhov tsis zoo, kev siv, kev siv tom qab, kev tshaj tawm, thiab kev daws teeb meem thiab rov ua dua. kuaj . Tej zaum koj yuav tau hnov cov theem sib txawv los yog siv koj tus kheej mus kom ze, kuv siv cov no vim kuv pom lawv ua tau zoo.
Qhov kev xeem nkag mus ntev npaum li cas?
1 - 3 lub lis piam
