Estou estudando algumas coisas no kernel GNU/Linux e encontrei os termos acima nas seções de Gerenciamento de Memória / Alocação de Memória, gostaria de saber o significado de ambos e o que são ?
Wireshark can detect these kind of activites, and warn us by a ‘duplicated ip address’ message. Why doesn’t the router act like this? The other way is to check the cache, and don’t allow two different ip address for a single mac address.
I think it is easy to prevent, but network hosts are just let it happen. Why?
As Route 53 is outside VPC, there is a chance for attack to corrupt records and cache of records in Route 53
Basic DNS protocol s have no means of authenticating responses
Does AWS provide security mechanism to protect the integrity of Route 53 cache?
I need some help in understanding the technique of Genians/Trustwave NAC regarding ARP poisoning. As seen here Bypassing Trustwave NAC, it looks like a good method, but I don’t simply get it. With ARP poisoning, the NAC device should send an ARP reply to any device which isnt on the trusted list. But this reply must be faster than reply of legitimate computer within network. What happens if any computer which is alive, answers faster for that ARP who-has packet? Any good explanation regarding this NAC technique?
