MIT Darpa Dataset,

Dear all,

I was wondering how normally people test their machine learning 
algorithims in MIT darpa dataset?

I asked this question because I found that :
1) There is a time gap between the published list of attack to the 
dataset. For instance APACHE2 attack, the published list of attack say the 
attack was start on 00:00:40 (not the fake time), normally I see the 
attack within +-10 seconds of the published list of attack (this is by 
looking directly on the payload)

2) Many of U2R attack are in port 23. For instance the attacker executes 
the command : $./exploit
In the real dataset especially for per packet model, it will get 
translated to many packets i.e
1st packet contains "$"
2st packet contains "."
3rd packet contains "/"
4th packet contains "e"

If the IDS identified say the 4th packet as anomalous , is it justifiable 
to say that the IDS detects the particular attack?

thanks

Wilmar Sulaiman
