From airborne systems to spacecraft to railway signalling systems, our V&V experts are supported by our own multi-purpose Software Validation Facilities which add flexibility to our services by supporting automated hardware, model and software-in-the-loop test environments according to the most stringent industry standards, including DO-178B/C Level A.

To this end, the software (or VNFs) from which such services are composed must be developed and delivered over very short time scales.

In order to guarantee the required levels of software quality within such tight schedules, software reliability tools must evolve.

Although many of the standards are tailored to meet the needs of specific industries, they all require similar development processes be applied in order to demonstrate compliance.

At the same time, these functional safety standards introduce a number of challenges for engineers and organizations developing these safety critical electronic components.

Critical systems are distinct in that they require a significant amount of Verification and Validation (V&V) activities in order to comply with industry certification requirements.

In fact, V&V can easily account for the biggest chunk of effort in the development of safety-critical systems.Crash OS: Hypervisor testing tool Abstract: Hypervisors are software more and more widespread because of the increasing usage of virtualization, especially in the Cloud. Crash OS is developed to test them and contributes to find security vulnerabilities in hypervisors.Gherkin Syntax Extension for Parameterization of Network Switch Configurations in Test Specification Abstract: We applied test automation in the style of Behavior-Driven Development (BDD), an agile software development technique.Functional safety refers to process oriented safety certification standards that are applied to embedded systems for validation.As an example, IEC 61508 is a well-known functional safety standard that has been adapted to different industries such as automotive (ISO 26262) and medical (IEC 60601) and shares similarities to safety standards in the aerospace industry (DO-178B and DO-254).Making sure that the embedded code that controls these devices is working as designed is of utmost importance.

    The images were collected in a searchable database, and used for experiments in facial recognition, to monitor known targets, and to discover new targets. for surveillance was taken because "Yahoo webcam is known to be used by GCHQ targets".
