Safety and security of cyber-physical systems

Safety and security of cyber-physical systems

on the physical plant and will eventually lead to failure. One possible mitigation is to limit the number of times that the secure platform can re-establish network connectivity. After the limit has passed, the secure architecture will completely isolate the system from the external network and operate using the safety controller – this is a fail-safe mode. After a certain amount of time passes, depending on the actual system requirements, network connectivity can be established again. Another approach is to increase the difficulty of performing repeated attacks by diversifying the software after each restart. For instance, one could compile multiple versions of the system software image where, on each version, modules are loaded into different static addresses. After every restart, one image will be picked randomly and loaded into the memory. This would stop the adversary from using the same parameters of the previous attack in the case of attacks that rely on static addresses e.g., buffer overflow attacks. Additionally, diversifying other parameters of the system (such as the assignment of port numbers) after each restart can further increase the complexity of launching attacks on the system.

Physical layer security for IoT applications

Physical layer security for IoT applications

In computational complexity and latency constrained emerging 5G applications, e.g., autonomous vehicles, haptic communications and enhanced reality, SKG at the physical layer could be considered as an alternative to currently used key agreement schemes. In this framework, the work present in Chapter 4 proposes i) a novel authenticated encryp- tion (AE) using SKG, and, ii) a pipelining mechanism of the AE SKG and the encrypted data transfer in order to reduce latency. Implementing the pipelining at the physical layer, the work investigates a parallel SKG approach for multi-carrier systems, where a subset of the subcarriers are used for SKG and the rest for data transmission. The parallel ap- proach is evaluated under power, security, rate and delay constraints. The amount of data that can be transmitted with a single key is determined by the cryptographic suites used, so that realistic key rate constraints can be identified. This allows to formulate the subcarrier allocation as a subset-sum 0 − 1 knapsack optimisation problem that is solved using i) the standard dynamic programming approach, and, ii) a greedy heuristic approach of linear complexity. Numerical evaluation shows that the proposed heuristic induces virtually no loss in performance. Furthermore, a comparison with a baseline scheme in which secret key generation and data transfer are performed sequentially, shows that the proposed par- allel approach offers gains in terms of efficiency. All of the proposed mechanisms, have the potential to pave the way for a new breed of latency aware security protocols.

Cyber-physical security of an electric microgrid

Cyber-physical security of an electric microgrid

Stuxnet-like worms are malicious codes that can be injected into a system through USB flash drives, shared networks, etc. Once Stuxnet is injected, it replicates to spread and hides by faking a healthy working condition of the system. To do this, the worm targets SCADA systems. In specific, it gets access to the programmable logic controller (PLC), infects it with harmful operational commands and returns previously recorded normal feedbacks to devices (sym, 2010). The undetectable mechanism of a Stuxnet-like worm makes use of the security vulnerability of a system along with rootkits to make the attack hard to be identified (Mueller and Yadegari, 2012). If an observer does not have valuation function to ascertain whether the state of the system is true or false, then the system is secure with respect to integrity. The operator cannot deduce if there is any fault or attack in the system. Thus, secure paths within a system are bad.

Cyber-physical security of a chemical plant

Invariant is a function, quantity, or property that remains unchanged when a specified transformation is applied. An invariant is a logical predicate on a system state that should not change its truth value if satisfied by the system execution. An axiomatic basis for the truth of invariants on cyber systems was first proposed by [9]. Most recently invariants are also known to be used in physical power systems [10] and water treatment systems [11]. Invariants are well-understood for cyber processes, but extending them into the physical domains requires some insight. We can arrive at invariant equations based on the physical or chemical properties of the system which can be used as an alternative source of information for the parameter under question. More on invariants is discussed in the further sections.

Network Security and Firewall Technology

Network Security and Firewall Technology

Certainly, the firewall itself also has its limitation, namely does not undergo firewall's invasion, the firewall is helpless, if is protected in the network through SLIP and the PPP way directly with the Internet connected internal user, will then create the safe hidden danger. This time, to guarantee the security, the firewall agent server when uses ISP SLIP and the PPP connection, needs to attach some new jurisdiction condition. At the same time, hardware way construction firewall, for example: PIX 520, it insufficiently nimble question also solidifies firewall's common question, therefore in an actual network movement environment, depends upon the firewall to guarantee that merely the network the security is insufficient obviously, this time, should act according to the physical demand to adopt the corresponding security policy.

Understanding Security Basics: A Tutorial on Security Concepts and Technology

In July and August 2003, they conducted a sur- veillance of the USAMRIID. The tactical informa- tion collected revealed similar problems. A large number of uniformed personnel made them very nervous. It just so happened that during their sur- veillance the USAMRID was conducting an anti- terrorism threat exercise, which also made them nervous. Additional security measures made it even more obvious that this site was well protected. There were many lights and security structures. They used barriers during the exercise. There were consistent access control procedures, not only at the building but also in the streets leading up to the building. In addition, there was a visible use of guards and posts. Their assessment was that this location was too diffi- cult.

In some circumstances there may be no proxy service available to terminate specific protocols in the PAZ. This circumstance applies primarily, but not exclusively, to encrypted protocols such as TLS (Transport Layer Security) and SFTP (Secure File Transfer Protocol). A risk assessment should be performed to determine the risks associated with terminating such traffic in the OZ, and the requirement for additional security controls.

Technology will shape the future of Physical Education

Introducing technology into Physical Education. This usually turns into quite an interesting discussion about what exactly do they mean by technology which is then typically followed up with concern over the replacement of Physical Activity for some sort of online alternative. Technology is all around us, it involves every aspect of Physical Education, from the shoes the students wear to the sports equipment used during the game. The introduction or emerging of digital technologies in Physical Education does not seek to replace physical activity; it aims to help explore physical activity.

Security, Privacy, and Technology Development: The Impact on National Security

Security, Privacy, and Technology Development: The Impact on National Security

Cybersecurity has become an essential element of life in the wired world. This is a highly dynamic universe where both the technology base and the threats continue to evolve. For some time now this world has moved into an era of “digital everything” with an almost seamless merger of communications, computing, and media of all kinds, including largely digital Big Data. Coupled with hardware and communications bandwidth that has become increasingly cheap, the marginal costs of communications are free or, in many cases, nearly so. All these factors—especially the rapidly developing and increas- ingly inexpensive technology and access to the Internet—have caused use of cyberspace to grow by orders of magnitude in a few short years. The enabling technologies and economics have also brought about some major changes in culture. Use of the net, devices, and advent of Big Data have brought about modern cultural artifacts from Internet

Communication Technology and Network Security

Communication Technology and Network Security

Security is a fundamental component in the Communication Technology and network Security. The first and foremost thing of every network planning, designing, building, and operating a network is the importance of a strong security policy. Network security has become more important to personal computer users, organizations, and the military. With the advent of the internet, security became a major concern. The internet structure itself allowed for many security threats to occur. Network security is becoming of great importance because of intellectual property that can be easily acquired through the internet. There are different kinds of attack that can be when sent across the network. By knowing the attack methods, allows for the appropriate security to emerge. Many businesses secure themselves from the internet by means of firewalls and encryption mechanisms. There is a large amount of personal, commercial, military, and government information on networking infrastructures worldwide and all of these required different security mechanisms. In this paper, I am trying to discuss current communication technology different kinds of attacks along with various different kinds of security mechanism that can be applied according to the need and architecture of the network.
