you can use:

DARPA Intrusion Detection Data Sets - MIT Lincoln Laboratory

may you please give me some more information about DARPA , i saw it , but didn't got any idea , what it is??

The KDD dataset is outdated! If you use them, it will be a major reason to reject your paper by most respectable journals!

Now depending on what type of IDS you want to optimize Anomaly vs Misuse or NIDS vs HIDS vs WIDS vs DIDS there are numerous well established databases

Anomaly/through classification 

1. UNSW-NB 15 (2015) https://www.unsw.adfa.edu.au/australian-centre-for-cyber-security/cybersecurity/ADFA-NB15-Datasets/

2. The CSIC 2010 HTTP Dataset in CSV format (for Weka Analysis) (2010) dataset is from a web penetration testing testbed for anomaly detection training. http://bit.ly/csic-2010-http-dataset-csv

3. Gure 2008 http://www.aldapa.eus/res/gureKddcup/

4. ECML/PKDD 2007 Discovery Challenge http://www.lirmm.fr/pkdd2007-challenge/#dataset

5. UNB ISCX (2010) http://www.unb.ca/cic/research/datasets/ids.html

6. NSL KDD Dataset http://www.unb.ca/cic/research/datasets/nsl.html

7. KDD99 http://kdd.ics.uci.edu/databases/kddcup99/kddcup99.html

8. The ADFA Intrusion Detection Datasets: mainly for HIDS/system calls https://www.unsw.adfa.edu.au/australian-centre-for-cyber-security/cybersecurity/ADFA-IDS-Datasets/ 

Wireless IDS

1. AWID http://icsdweb.aegean.gr/awid/ 

Misc traces and date sets

1. Publicly available PCAP files http://www.netresec.com/?page=PcapFiles

2. UCSD Network Telescope Dataset on the Sipscan http://imdc.datcat.org/collection/1-06Y5-B=UCSD+Network+Telescope+Dataset+on+

3. CTF traces (6 years old) https://github.com/zed-0xff/ctf

4. http://www.cs.ucsb.edu/~kemm/courses/CS595/TestingIDSs/

5. http://www.secrepo.com/

6. The Attack Challenge - ECML/PKDD Workshop (2007) dataset contains web penetration testing data.

Thank you Mr. Monther..It is a great help...
