i know that acording to some microsoft papers, i can prevent sync attacks
Sync attacks, or SYN attacks?
in every compurter by modifying the registry (at least in win nt 4.0 & 5.0). In a large network this only means one thing: tons of work without forgetting this may carry another tons of problems if we are not cautious enough...
I'm not sure where you got that idea. The Registry change (for SYN attacks, anyway...don't know what you're referring to regarding SYNC attacks) can be scripted using batch files or Perl very easily. When rolling out the change, of course, you'd want to run it on designated test systems first, in order to identify any issues that should occur. That's your "caution".
but i was wondering if there is such a way to prevent sync attacks from an upper level, like for example cisco switches or routers, may be a firewall?
Actually, yes...in most cases. RTFM. --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute. Mention this ad and get $545 off any course!
