In the recent plans for the Swedish total defence, there has been an increased focus on grey zone and hybrid threats. An antagonist's strategy to influence or cause unrest without creating an escalated reaction is not in itself something new. However, in a society based on openness, digitisation and dependencies between different societal functions, these threats make society all the more vulnerable. The vulnerabilities and threats that are discussed in this report cover the following areas: - Market conditions set the playing field for companies as well as antagonists - The transport system's openness and accessibility can be used by an antagonist - Intrusion and interference could affect operations and systems - Security risks occur during public tending and using goods and services - Dependencies create vulnerabilities - Challenges for the development of coherent defence readiness Finally, this report concludes that a well-functioning society creates a threshold effect that deters a possible antagonist from acting. Transportation is a vital part of a functioning society, and is of crucial importance in a situation where we are faced with a threat. Having robust supply systems is an important base, in war as well as in peace. It is important to raise the awareness of antagonist threats in order to achieve resilience.
