• Research on WSN IDS!

• Drops on a Hot Plate!

• No Holistic Solutions!

• Almost no Algorithm can be Proven Secure!

• Passes by on Actual Problems!

• Securing WSNs!

• Impossible to Really Fully Secure!

• Resources are Scarce!

• Security = Non-Functional Additional Cost

• Not Another Drop on a Hot Plate!

• Address Actual Problems!

• Support and Nurture Future Research!

• Leverage Prior Experience in New Context

• Offer a Solution that Encompasses!

• Research! ! ! ! ! simple & formal ! ! ! ! ! ! ! ! specification!
