Cybersecurity in Complex Networked Embedded
Systems Current Status
  • Ubiquitous connectivity
  • Usage of IP technology for private networks
  • Private networks intersect the Internet
  • SCADA systems are becoming built with COTS
  • Increase of system vulnerabilities!

Cybersecurity in Complex Networked Embedded
Systems Future
  • Long term goal
  • exchange of information among trusted parties,
    on a peer-to-peer base, wherever it is needed,
    whenever it is needed
  • Priority System Monitoring
  • Need Predictable and robust large scale data
    distribution

8
Where are we?
  • Data distribution
  • bringing data information to the right people at
    the right time
  • Data distribution is (more or less) predictable
    and robust in small scale environments (see
    RTI-DDS and OpenSlice products)
  • Data distibution is best effort on large scale.
    Problems in
  • scalability
  • timeliness
  • ordering
  • dynamic discovery of peers
  • persistence
  • How to enable predictable and robust data
    distribution on large scale?

9
Important Results from distributed systems in the
last 10 years
  • Peer-to-peer systems
  • Sensors Networks
  • Mobile ad-hoc networks
  • Autonomic computing and communication
  • Event based systems (Publish/subscribe systems)

Problems to be solved to enable this vision
  • Network level From client-server to peer-to-peer
    (autonomous) network management and trust
  • Overlay network level security, robustness,
    predictability, topology control
  • Data Dissemination level QoS tradeoffs, QoS
    graceful degradation issues

12
Industry
  • Moving from static to dynamic network management
  • Instrumenting overlay network tools
  • Moving from small scale data distribution to
    large scale one
  • Implements basic functions of data distribution
    on the ground

13
Timescale for research progress
  • Parallel and intersecting process among basic
    research, RD for getting products asap
  • Peer-to-peer network management
  • Basic research yr 6
  • RD yr 8
  • Products in 7 years
  • Rapid deployable and customizable overlay
    networks
  • basic research yr 5
  • RD yr 7
  • Products in 5 years
  • Large scale Data Distribution services
  • basic research yr 7
  • RD yr 7
  • Products in 10 years

14
Conclusion
  • Data distribution for large scale networked
    embedded systems is a priority
  • Many research issues inside for getting the
    required QoS
  • Network level
  • Overlay network level
