BGP related question

["Shah, Parthiv" <Parthiv.Shah () theclearinghouse org>]

My apology if I am asking for a repeat question on the list. On 7/29/13 I read an incident about accidental BGP 
broadcast see article here https://isc.sans.edu/diary/BGP+multiple+banking+addresses+hijacked/16249 or older 2008 
incident http://www.renesys.com/2008/02/pakistan-hijacks-youtube-1/

My questions:


1)      I would like to understand how can we detect and potentially prevent activities like this? I understand native 
BGP was not design to authenticate IP owners to the BGP broadcaster. Therefore, issues like this due to a human error 
would happen. How can activities like this be detected as this is clearly a threat if someone decides to broadcast IP 
networks of an organization and knock the real org. off the Net. 2) In reference to prevention, I recall there were 
discussions about secure BGP (S-BGP), Pretty Good BGP, or Secure Original BGP but I don't remember if any one of them 
was finalized (from practicality viewpoint) and if any one of them is implementable/enforceable by ISPs (do anyone have 
any insight)? 3) If I was to ask for an opinion, from your viewpoint which one is better and why and which one is not 
doable and why not?

Thank you in advance,
Parthiv
