The development of cyberspace with the increased use of artificial intelligence creates a new environment. It opens both new possibilities and generates new opportunities. However, these developments also involve vulnerabilities and risks, which are considerable and must be taken into account. Because this evolution is unavoidable and all domains will be equally challenged, it is an obligation for all actors of cyberspace to contribute together to its security. This presentation aims to show what the real dangers are in cyberspace linked with the ongoing evolution as well as possible and necessary security measures.
