DESCRIPTION:Imagine your car's brakes **stop responding**. Not because of a
  mechanical fault\, but because a **security system** is drowning out the 
 signal. That is not science fiction. It is what can happen when intrusion 
 detection goes wrong inside a **real-time vehicle network** built for spee
 d\, not security.\n\nWhile researching for my MSc dissertation\, I simulat
 ed **five attacks** against a virtual CAN bus. Some were loud and obvious.
  Others slipped through silently\, exactly as a real attacker would intend
 .\n\nBut detecting the attacks was not the hardest part. **Doing it withou
 t destabilising the same safety-critical systems I was protecting** turned
  out to be. Rule-based detection missed the quiet ones. Machine learning f
 lagged too much. **A hybrid approach combining both** was the only method 
 that handled the full range reliably.\n\nThis talk explores what actually 
 happens when **security meets a moving car**\, and why detecting attacks i
 s meaningless if the **defence itself becomes the risk**. Attendees will l
 eave with a clearer picture of what it actually takes to **defend a vehicl
 e network** responsibly.
