5. Conclusion

Information systems are exposed to threats against which they must be protected. Intrusive testing and risk analysis methods can first reveal their vulnerabilities. A number of technical solutions are then available to provide effective countermeasures.

The field of cybersecurity is currently booming, partly because technologies are evolving and countermeasures need to adapt, and partly because attackers are constantly developing new techniques to try and circumvent these countermeasures.

In recent years, companies have become fully aware of the challenges of cybersecurity, and have adapted their organizations and processes to manage it.

Software can be certified to prove that it has been developed in compliance with the rules of cybersecurity standards, and will therefore have a satisfactory level of robustness....
