“…Except from DynSec, all the DSU systems targeting compiled applications present a dynamic patches building toolchain. In case of DSU systems designed for operating system kernels, LUCOS [20], DynAMOS [21] and KSplice [17,22] (and its successors KGraph and KPatch) target the Linux kernel while K42 is the operating system kernel itself, designed to provide customizability, scalability and maintainability [23][24][25][26]. PROTEOS [27,28] is designed for the MINIX 3 operating system, which is compatible with the POSIX interface [29].…”

Higher interconnectivity among devices, machines, the cloud and humans is envisioned in the actual trend of automation, also known as Industrial Internet of Things (IIoT). These industrial control systems, which may require high availability and/or safety related capabilities, are no longer isolated from the corporate environment or Internet. Software updates will be needed during the product life cycle, due to the long service life, the increasing number of security related vulnerabilities discovered on these industrial control systems and the high interconnectivity desired in IIoT. These updates aim at fixing all these security weaknesses, bugs and vulnerabilities that could appear, while the required safety integrity levels are ensured. Security-related concerns have just been addressed by the safety engineering community, because of the increasing number of cyber-attacks against safety-critical systems, such as Stuxnet. Moreover, system shut-downs caused by software updates could not be plausible when high availability is required. Typically, in order to perform the software update, the whole industrial process or the production is halted, so that the software upgrade is safely applied. However, this scenario might not be applied in critical infrastructures, such as nuclear or hydroelectrical power plants, where these production and service interruptions are not acceptable from the business and service point of view. This article presents an analysis of existing dynamic software updating techniques, which may be applied for safe and secure industrial control systems. These techniques aim at updating the running code, without the need of a halt and restart, increasing the availability of the industrial system.

“…In such a situation, it is important to have an OS that would allow application of software updates and patches without any downtime or loss of service (Baumann and Appavoo, 2005). Even rebooting or restarting could be deferred without losing the ability to apply security fixes or enhance functionality through software updates provided the system is available at all times.…”

It is very important to improve the design of the real-time operating system (RTOS) especially if we want to use it in some special devices. Numerous researches have accepted conventional RTOS as being the customary approach for designing devices used by children. This is because these are able to facilitate the implementation different criteria such as clustering, stability and alternate programs. In this paper, numerous publications have been analyzed to observe the performance of the RTOS when it is subjected to varied constraints. The study focuses on a review of RTOS in relation to play models to analyze their capabilities on various computing platforms and OSs. The publications which we have collected have been sorted out to comprehensively review thereby leading to the configuration of several factors affecting the features within the system. Likewise, statistics and results have facilitated adoption of a more focused approach towards the development of RTOS. While this program ranks clustering and performance as being the highest RTOS criteria for all applications, alternate programs considered this to be the least important. Thus, criteria choice becomes an important issue to address.

“…The overhead of the transaction mechanism makes it inadapted to be used in embedded devices with limited resources. Reconfigurable operating systems including Synthetix [28], MMLite [18] or more recently K42 [1,33] provide mechanisms for dynamic reconfiguration at a fine grain. Synthetix and MMLite use readwrite locks to synchronize accesses to a reconfigurable component.…”

Supporting dynamic reconfiguration is required even in highly constrained embedded systems, to allow patches and updates to the embedded systems software, and to allow adaptations to changes in environmental and operating conditions without service interruption. Dynamic reconfiguration, however, is a complex and error prone process. In this paper we report our experience in implementing safe dynamic reconfigurations in embedded devices with limited resources. Our approach relies on a component-based framework for building minimal and reconfigurable operating systems and the use of a domain specific language (DSL) for reconfiguration.
