A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : IPFIX IE Extensions for DDoS Attack Detection Authors : Tianfu Fu DaCheng Zhang Liang Xia Min Li Filename : draft-fu-dots-ipfix-extension-01.txt Pages : 21 Date : 2016-06-13 Abstract: DDoS Open Threat Signaling (DOTS) Working Group is for developing the standard signaling mechanisms, together with the DDoS related telemetry and threat handling requests and data transmitted by them used in DDoS problem space. Although IP Flow Information Export (IPFIX), Packet Sampling (PSAMP), and Packet Selection methods are useful for network security inspection, there are still some gaps existing to identify some categories of DDoS attacks. To fill in the gaps, this document describes the connection sampling mechanism and explains why it is needed for detecting DDoS attacks. It also defines several new IPFIX Information Elements (IEs). Then, it presents some examples to show how to use these new IPFIX IEs together with the existing IPFIX IEs to detect specific DDoS attacks. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-fu-dots-ipfix-extension/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-fu-dots-ipfix-extension-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-fu-dots-ipfix-extension-01 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
