ESXi Security

Hello everyone,

I am a trainee in VMware security and I have to carry out a study about the security of the ESXi environment.

However I only found a paper about the security issues of ESX2 dated back from 2004 which seems quite as Service Console is still mentionned within although it has been replaced ...

Could someone help me and provide me with some interesting papers about the general architecture of ESXi and maybe papers about the security issues or at least drafts ?

Thanks a lot
