Cybersécurité, IOT automobile et aéronautique

  1. 1. Cybersécurité, IOT automobile et aéronautique Jacques PANTIN Janvier 2017
  2. 2. De nouvelles problématiques de sécurité • Les menaces – Potentiellement des risques de mort d’homme (il n’y a plus seulement des problématiques de protection de données personnelles (RGDP, CNIL)) – L’utilisation d’objets, réseaux de ‘zombies’, comme vecteurs d’attaque (cf les évènements récents avec Mirai) – L’espionnage industriel • Les vulnérabilités – Des contraintes de coût (‘le composant à 2 $’) qui limitent la mise place de solutions de sécurité – Des schémas d’architecture de sécurité pas encore pleinement maîtrisés – Le besoin d’une stabilité dans le temps Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  3. 3. Des approches très différentes selon les domaines Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités Automobile Aéronautique Smart buildingsSmart cities Domotique Santé
  4. 4. De nombreux défis • Un spectre fonctionnel très large et des normes multiples – En automobile • V2X (Vehicle to Everything) • V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure), ITS (Intelligent Transport System) • … – En aéronautique • Sesar (Single European Sky ATM Research), NextGen • ATA e Business Program (Air Transport Association) • … • En automobile, une frontière conducteur/véhicule pas encore stabilisée • Des problématiques d’interopérabilité • Une recherche d’ergonomie omniprésente (orthogonale à la mise en œuvre de ‘réponses sécuritaires’!!) • Des contraintes de côut • Une nécessaire stabilité dans le temps • … Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  5. 5. Une première typologie des risques • La ‘pollution’ de l’équipement terminal • La prise de contrôle des concentrateurs (cf l’incident Tesla) • L’interception des échanges (écoute, altération des msg) • Le détournement des données • L’interception des firmwares et logiciels sur les équipements terminaux (espionnage industriel)Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  6. 6. Les objectifs de sécurité • Avec ISO 26262 (ASIL- Automotive Safety Integry Level) – S: Sévérité – E: Exposition – C: Contrôlabilité • Avec EBIOS • Disponibilité • Intégrité • Confidentialité • Traçabilité Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités • Avec ISA99 (SAL- Security Assurance Level) • Contrôle d’accés, Contrôle d’usage • Intégrité, Confidentialité, Disponibilité • Restriction sur les flux de données • Réponse adaptée à une incident
  7. 7. Sécurité: les domaines d’action • Intégrité de l’objet – Intégrité des composants – Absence de malwares • Sécurité des communications • Protection des données (en particulier, données personnelles) – Attaque sur l’objet – Attaque sur les bases d’information Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  8. 8. Nos objectifs: Le safeboot • Objectif: – La validation de l’intégrité de la configuration logicielle lors du démarrage de ‘l’objet’ (validation des signatures des composants logiciels critiques, en face d’une configuration de référence) • Défis: – Niveau de sécurité souvent faible associé à des solutions d’abord logicielles (pas de eSE) – Outils de gestion de configuration nécessaires – Interopérabilité entre espaces de confiance difficile à gérer Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  9. 9. Nos objectifs: La traçabilité • Des acteurs multiples – Equipementiers / Constructeurs / Gestionnaires de flotte / Mainteneurs – Garagistes • Des espaces de confiance nécessairement interopérables • Des principes d’habilitation à la fois sûrs et simples à mettre en œuvre • Une utilisation de la blockchain??? (usage en micro paiements???)Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  10. 10. Une nouvelle approche de la sécurité La démarche classique ne suffit plus – Sécurité et sureté (Security / Safety) – Security inside (CMM) – Résilience – Sécurité et qualité – …. Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
  11. 11. Une gouvernance différente • Des analyses de risques différentes – Un très bon travail de l’ANSSI • Pertinence du RSSI d’aujourd’hui?? • Comment prendre en compte la sécurité dans des systèmes techniques? • Les normes COBIT for info sec, ISO 26262… Janvier 2017 – DICTIS- Droits de diffusion et de reproduction limités
