Abstract. The concept of security has shifted from territorial integrity to human security and, after 9/11, to pre-emptive security. Based on the massive implementation of surveillance-oriented security technologies (SOSTs), pre-emptive security emphasizes anticipation of threats and risk management. While liberty and security get framed as standing in a trade-off, SOSTs are massively deployed to increase security. Due to the mutually constitutive relationship between SOSTs and pre-emptive security, security gets framed as a function of surveillance, forcing increasingly monitored citizens to exchange liberty for security. In contrast, a systemic approach to security may enable security policies pursuing liberty and security.
