Systems Unification Approach & Security Assurance Process

This research security system quotes assurance for safety-critical systems, where security and safety are addressed before going to actual implementation/development phase for component-based systems. For this purpose, require a conceptual idea or strategy that deals with the application logic security assurance issues. This may explore the vulnerability in single component or a reuse of specification in existing logic in component-based system. Keeping in view this situation, we have defined seven concepts of security assurance and security assurance design strategy for safety-critical systems.

The integration of components into industrial control systems such as railway control and management systems (CCS) is ongoing of commercial off-the-shelf hardware and software (COTS). However, the use of COTS components in a pre-owned security framework results in new security risks. The interplay of security is an important field of study in which several questions still need to be addressed. To mitigate risk and ensure the programme is dependable and secure; security assurance is an essential part of the safety-critical software development process.

Deficiencies in infrastructure and deficiencies also can lead to software bugs and abuse by hackers and offenders seeking to manipulate flaws in the tech industry. Testing, accreditation and evaluation are carried out to justify the level of assurance of safety of logical function during the intercommunication interaction process. This strategy is applied at design stage that refers to traditional use to increase the trust of the programme in the programme validation process [1].

Software assurance during the engineering/development process has been an integral aspect of contemporary safety-critical systems’ overall innovation, ranging from weapons, avionic, even automotive control systems, industrial control systems and medical equipment. Software is used for tracking and regulating physical processes in these systems increasing failure may lead to loss of life or other catastrophic malfunction. Therefore, software assurance for safety-critical systems performs a role as backbone in commercial-off-the-shelf component-based system [2].
