Machine Learning for IDS: which dataset?

[trantichphuoc () yahoo com]

Hi there,
I am interested in applying machine learning algorithms in detecting network intrusions. I read many papers and 
realized that the KDD-99 is the most well-known dataset used in the field. However, this dataset is provided by MIT in 
1999, and obviously, its pretty old. As we all know, the defensive technologies are fast, and also the hacking 
techniques. Clearly, the KDD-99 dataset would not provide the true representation of a network at the current time. So, 
could anyone plz tell me which dataset is more updated, specialized for machine learning research in IDS?
Thanks
Patrick
