Subject:Re: Session ID Generation
View as plain text  
Tanks for responding Johan.

I am indeed looking for MySQL session ID's, not an HTTP session ID.  I'm
doing a defense in depth audit and reviewing potential threats to each
remote connection - in this case session fixation.  I know I can set
various session timeout properties that help mitigate fixation and
hijacking, but a randomly generated server-only generated session id goes a
log way to mitigate the risk.  Just a note, we are following industry best
practices utilizing a DMZ...but out biggest threat is an insider, so we
need to realize any potential risk.

You stated these IDs are sequential...do you know if there is any way to
modify this to utilize a "random" generation?  Sequential session IDs are
an avenue to session hijacking.

Thanks,

S
