Cyberspace is the complex socio-technical environment that is often called the '5th domain', next to land, water, air and space. As the news brings announcements of new cyber incidents on an almost daily basis, sometimes with high impact, there is an urgent need to better secure cyberspace. Both technical and human factors are of importance to do so, which is the rationale underlying this theme.
Securing Cyberspace means:
- Understanding risks
- Designing measures to reduce risks to acceptable levels.
By understanding risks we mean understanding the relationships between threats, incidents, and expected impacts, in all domains of cyberspace. The basis for understanding these relationships is a deep knowledge of what exactly happens in cyberspace and cybersituation awareness. Both cyber monitoring & analytics and public-private information sharing are key challenges in order to collect enough knowledge for predicting possible future cyber incidents and related impacts.
Design of measures to reduce existing risks to acceptable levels
Cyber security measures entail a broad spectrum of technical, legal, ethical and organizational issues over many organizations where public-private-partnership (PPP) is (again) a key issue: this involves complex cyberspace governance issues like institutional arrangements between various stakeholders that clearly define their (delegated) responsibilities.
Since cyberspace is a recently established domain with very specific characteristics, such as being real-time, partly autonomous, with almost 3 billion actors (both enablers and users) connected, the cyberspace governance challenges are unique and require new forms of international cooperation.
