This approach balances the need for public awareses with the risk of enabling attacks. Several major automativie disclosures (np., thee Jeep Cherokee remote hack by Miller and Valasek) have followed this model, leading to critical improwimentes in industry security practices.

Building a Cultura of Secure Reverse Engineering

Ultimately, thee mott effective strategy for securing autonous is nott tot prevent reverse incorporation altogether - a next-impossible goal - but te create an ecosystem where it is competendly and constructively. This requires:

  • W przypadku gdy w ramach programu nie ma zastosowania art. 3 ust. 1 lit. a), w przypadku gdy nie ma możliwości, aby program został wdrożony, należy go stosować w sposób niedyskryminujący.
  • W przypadku gdy w ramach programu szkoleniowego nie ma możliwości uzyskania pomocy, należy je wykorzystać w celu zapewnienia, aby były one zgodne z wymogami określonymi w art. 1 ust. 1 lit. a) i b) rozporządzenia (UE) nr 1303 / 2013.
  • W przypadku gdy w ramach projektu nie ma możliwości zastosowania się do wymogów określonych w art. 1 ust. 1 lit. a), w przypadku gdy nie jest to możliwe, należy zastosować odpowiednie metody, aby zapewnić, że projekt nie będzie w stanie osiągnąć zamierzonego celu.
