The NIST (National Institute of Standards and Technology ) released yesterday 3 new documents:

1. SP 800-45 Version 2, Guidelines on Electronic Mail Security
2. SP 800-94, Guide to Intrusion Detection and Prevention Systems (IDPS)
3. SP 800-97, Establishing Wireless Robust Security Networks: A Guide to IEEE 802.11i

I was just reading the 3 and they are very good. I really liked the IDPS document, with great updates since the Intrusion Detection System document, explaining the concepts, with good real world examples.

It was interesting to see how the documents complement each other. The E-mail document has good references to IDPS, which also include good information regarding WLAN...really nice and I recommend you to take a look at least on the Table of contents. I am sure you will continue the reading...!:)
