Kulesi sihloko, imisebenzi emi-5 yokuqala izokufundisa izisekelo zokuhlaziywa kwethrafikhi yezivumelwano ezahlukahlukene zenethiwekhi.
ulwazi lwenhlanganoIkakhulukazi kulabo abafuna ukufunda okuthile okusha futhi bathuthuke kunoma iyiphi indawo yolwazi nokuphepha kwamakhompiyutha, ngizobhala futhi ngikhulume ngezigaba ezilandelayo:
- I-PWN;
- i-cryptography (Crypto);
- ubuchwepheshe benethiwekhi (Inethiwekhi);
- reverse (Reverse Engineering);
- i-steganography (i-Stegano);
- ukusesha nokuxhashazwa kobungozi be-WEB.
Ngaphezu kwalokhu, ngizokwabelana ngolwazi lwami ku-forensics yekhompyutha, ukuhlaziya uhlelo olungayilungele ikhompuyutha kanye nokuhlaziywa kwe-firmware, ukuhlaselwa kwamanethiwekhi angenawaya namanethiwekhi endawo, ukwenza ama-pentest kanye nokuxhaphaza ngokubhala.
Ukuze ukwazi ukuthola mayelana nezihloko ezintsha, isofthiwe nolunye ulwazi, ngidale ΠΈ endaweni ye-IIKB. Futhi izicelo zakho siqu, imibuzo, iziphakamiso kanye nezincomo .
Lonke ulwazi luhlinzekelwe ngezinjongo zemfundo kuphela. Umbhali walo mbhalo akathwesi icala nganoma yimuphi umonakalo odalwe kunoma ubani ngenxa yokusebenzisa ulwazi nezindlela ezitholwe ngenxa yokutadisha lo mbhalo.
Ukuqinisekiswa kwe-FTP
Kulo msebenzi, sicelwa ukuthi sithole idatha yokuqinisekisa endaweni yokulahlwa kwethrafikhi. Ngesikhathi esifanayo bathi le FTP. Vula ifayela le-PCAP ku-wireshark.
Okokuqala, ake sihlunge idatha, njengoba sidinga kuphela iphrothokholi ye-FTP.
Manje ake sibonise ithrafikhi ngokugeleza. Ukuze wenze lokhu, ngemva kokuchofoza kwesokudla, khetha Landela i-TCP Stream.
Sibona igama lomsebenzisi nephasiwedi.
Ukuqinisekiswa kwe-Telnet
Umsebenzi ufana nowangaphambili.
Sithatha ukungena ngemvume nephasiwedi.
Uhlaka lwe-Ethernet
Sinikezwa ukumelwa kwe-Hex kwephakethe lephrothokholi ye-Ethernet futhi sicelwa ukuthi sithole idatha ebucayi. Iqiniso liwukuthi ama-protocol ahlanganiswe eyodwa phakathi kwenye. Okusho ukuthi, endaweni yedatha yephrothokholi ye-ethernet kunephrothokholi ye-IP, endaweni yedatha lapho iphrothokholi ye-TCP itholakala khona, kukhona i-HTTP, lapho idatha itholakala khona. Okusho ukuthi, sidinga kuphela ukuqopha izinhlamvu kufomethi ye-hex.
Isihloko se-HTTP siqukethe idatha yokuqinisekisa eyisisekelo. Siwaqoka ku-Base64.
Ukuqinisekiswa kwe-Twitter
Siyacelwa ukuthi sithole igama-mfihlo lokungena ku-twitter endaweni yokulahlwa kwethrafikhi.
Kunephakheji eyodwa kuphela. Masiyivule ngokuchofoza kabili.
Futhi futhi sibona idatha yokuqinisekisa eyisisekelo.
Thola igama lomsebenzisi nephasiwedi.
Ifayela le-Bluetooth elingaziwa
Baxoxa indaba futhi bakucele ukuthi uthole igama nekheli le-MAC locingo. Masivule ifayela ku-wireshark. Thola ulayini Isicelo Segama Elikude Siqediwe.
Ake sibheke izinkambu zaleli phakethe, lapho kuboniswa khona ikheli le-MAC negama locingo.
Sithatha i-hashi futhi siyinikeze.
Kulo msebenzi, sizoqedela ukuhlaziya ama-puzzle alula esihlokweni samanethiwekhi (okuningi kwabaqalayo). Kuya kuba nzima nakakhulu... Ungasijoyina . Lapho ungaphakamisa izihloko zakho futhi ubambe iqhaza ekuvoteni ukuze ukhethe isihloko sezihloko ezilandelayo.
