Hovori sa, ze na kazdu zbran existuje aj protizbran. Maloktora ochrana sa ponima ako naozajnepriestrelna. Ide o tom, ze pripadnemu narusitelovi sa to stazi a da sa ocakavat, ze velke % to nebude vediet prekonat.
Napr. kedysi som uvazoval nad ochranou na LAN sietach takym sposobm, ze nebudem kontrolovat len MAC adresu (a na zaklade toho pridelovat IP), ale budem aj pozerat HOST name, pod ktorym sa PC registruje do DHCP servera. Takze by nestacilo spoofovat MAC adresu. Vo svojej podstati primitivna ochrana, ktora by vsak niektorym mozno zabranila kradnut MAC/IP adresy (pokial by nepochopil, v cem delo, po com by to velmi rychlo prekonal). |

Mna skor zaujima ci to funguje aj v praxi. Lebo je mozne ze niektore routre seru na nejake pravidla. Mal som jeden ktory neznamo akym sposobom sral na mac adresu. Doteraz to nechapem ale mam na sieti zamok mac/ip a po vymene tohto routra zostal v arp tabulke povodny staticky zaznam zo starou mac adresou zariadenia. Prisiel som na to jedine tak ze som nasiel packety ktore boli smerovane inde v uplne inom segmente siete lebo bridge nevedel kde to ma poslat (na zaklade mac) tak to islo vsade. Interet ale za routrom isiel bez problemov. Neviem ale ten switch ignoroval mac adresu a komunikoval len na zaklade ip ale to bude skor vynimka... |
