IoT – IEC61508

The cost of quality or functional safety defects in the field for systems that are hard to update is very high, with the potential for damaging trusted relationships with customers. With growing systems complexity and accelerating release cycles, software engineering groups look to a Static Code Analysis MISRA solution to prevent code defects before they reach testing or the customer.

By applying the Klocwork Quality Standard (KQS) checks to new or existing projects, software defects are classified into categories such as suspicious code practices, resource leaks, maintainability, performance, and more can be analysed. The Klocwork Quality Standard report can also be enhanced by running Cyclometric Complexity reports to help the development team pinpoint high levels of inherent complexity and ultimately set about the task of reducing the level. Technical Debt

The Klocwork Quality Standard is the basis for the built-in Klocwork Quality Report. This report provides an at-a-glance health check for your software project. Review items such as the trends for the top 3 quality issues and areas of source code with the most quality concerns.

 

Organisations looking to improve the quality, security and analysis of their code early in the development life cycle are adopting the MISRA standards to add the benchmark elements of rigor and consistency into their process across all of their application deliveries. As well as adding a coding best practice, auditing and reporting is made much easier due to the enormous knowledge and experience that comes along with the standards.

Klocwork is being used successfully in safety-critical and high-integrity embedded systems where system faults are simply not acceptable and, in many cases, compliance with industry standards is required (IEC 61508, ISO 26262, EN 51208, IEC 62304, DO-178B/C, MISRA etc).

Klocwork includes built-in checkers to support all of the leading Security standards CWE, CERT, DISA STIG, CWE/SANS Top 25, OWASP, MISRA. Klocwork also allows organisations to quickly introduce their own customised security checkers to meet the ever-changing threat landscape.

Trapping security vulnerabilities

Defensive coding through automation with a threat model in hand, developers can begin to drill-down and identify the specific security vulnerabilities that could expose their embedded software to risk. Programmers, however, aren’t security experts and can miss common security gaps, logic errors, and concurrency violations that expose code to external threats.

Automated static code analysis (SCA) tools can assist embedded software developers by helping to eliminate security vulnerabilities early in the development cycle. While automotive software development teams are familiar with traditional SCA tools, they’re limited to finding programmatic bugs only. Modern tools can detect security vulnerabilities and defects as the developer is writing code. This helps developers build security into their code and reduce risk as early as possible, without burdening the project with a lengthy defect-testing phase.

Static analysis tools can identify hundreds — if not thousands — of security vulnerabilities, including critical vulnerabilities such as buffer overflows, uninitialized data, use of dangling pointers, injection flaws, and the use of known insecure APIs and libraries.
