Cyber-Physical Systems: Security Threats, Countermeasures and Issues

This presentation delves into the domain of cyber-physical systems (CPS), highlighting their integration of physical and cyber components, including IoT, big data, and cloud computing. It examines CPS features, such as embedded systems, interoperability, and data flow, along with the architectural layers from physical to application. The presentation identifies security threats like spoofing, data tampering, and denial of service, while also exploring research areas such as attack modeling and security architecture. Countermeasures discussed include SCADA and smart grid security. The presentation concludes by suggesting future research directions, including the development of authentication techniques, metrics for trust, and ensuring data security within CPS environments. The presentation draws on several key sources, including works by Lee and Seshia, Liu et al., Massey, Monostori et al., and Yu and Xue.

INTRODUCTION
The presentation deals with the cyber
physical systems and the problems of
security in these physical systems. The
presentation also focuses on the
features and the countermeasures of
the security threats on these systems.

CYBER-PHYSICAL
SYSTEMS
 It is a system that can combine physical
and cyber components
 They consists of network monitors,
embedded computers and controllers
 The important technologies under these
systems include IoT, Big data, cloud
computing
 They are used in smart vehicles,
wearables, smart medicines and many
more

FEATURES OF CPS
 Embedded and mobile sensing
 Capability to adopt and train
 Interoperability via the use of internet
 Interaction of physical and cyber
components
 Data flows and cross-domain sensor
sources

ARCHITECTURE OF CPS
The architecture of Cyber-physical
systems consists of :
 Physical layer
 Data link layer
 Network layer
 Transport layer
 Sessions layer
 Presentation layer
 Application layer

PHILOSOPHICAL ISSUES
 Generation of more information leading
threat of security
 Increase in the information noise due to
more information generation
 Search of information become a
complex task
 Barriers includes barriers and standards.

SECURITY THREATS
 The threats affect the integrity,
confidentiality and availability of data
 The threats of CPS include:
 Spoofing identity
 Tampering of data
 Disclosure of information
 Denial of service
 Elevation of privilege

MAIN RESEARCH AREAS
 Estimation of consequences of cyber
attacks
 Modeling of attacks of CPS
 Detection of attacks of CPS
 Development of an architecture of
security

COUNTERMEASURES
The countermeasures those are devised
in order to stop the attacks on CPS
include:
 Security system of SCADA
 Security of smart grid
 Communication security

OPEN ISSUES
 The creation of techniques for CPS
mechanism authentication
 The development of metrics to decide
level of hope in CPS
 Creation of techniques for making sure
security of data
 Creation of CPS architecture.

CONCLUSION
The presentation deals with the cyber-
physical systems those are prone to
cyber threats. This presentation deals
with the countermeasures of these
threats and issues. Moreover, future
research areas of CPS are found that
includes architecture of CPS, level of
trust in CPS, ensuring security of
personal data and many more.
