This is, however, much more complex than it might seem at first sight, since the total cost of security does not just contain the upfront investment costs in security equipment, training, management, etc., but also much less tangible effects like the value of time, effects on system functionality (e.g. logistic systems), macro-economic effects (on GDP), the [[Opportunity cost|opportunity cost]] of public spendings on security, and consumer preferences/behaviour (e.g. the dislike of very present security measures like screening of personal belongings).

  &lt;td class=&quot;diff-deletedline diff-side-deleted&quot;&gt;&lt;div&gt;Estimation of the expected benefits of security measures is the second step. These benefits basically depend on the magnitude of the risk of a security threat (crime and terrorism) and the reduction in these expected losses (in economic terms). Hence, if the risk of a certain event is low, the potential benefits of improved security will also be low, no matter how expensive this measure is&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;&amp;lt;ref&amp;gt;&lt;/del&gt;Or, the other way around: If a certain risk is very high, even a small risk reduction will generate substantial benefits&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;.&amp;lt;/ref&amp;gt;&lt;/del&gt;. Since both the magnitudes of risks and the impact of security measures are difficult to estimate, it can be helpful to think in terms of how much a certain security measure should reduce the risk of a security threat to be cost-effective. For example, if surveillance measures in a particular urban area cost 10 million euro per year, and the expected losses of crime and terrorism in that area are 100 million euro per year, a 10 percent reduction in risk would justify the cost of this surveillance measure (assuming it is realised by this particular security option, and not different measures or circumstances). To do this, economists use different sets of assumptions and parameters about criminal and terrorist behaviour, crime statistics, risk assumptions, etc. enabling them to analyse the cost-effectiveness of a single or multiple security measures&amp;lt;ref&amp;gt;In practice, serious targets like transportation hubs or utility objects are hardly ever protected by a single security measure. See e.g., Jackson &#039;&#039;et al&#039;&#039;  (2012): Efficient Aviation Security. Strengthening the Analytic Foundation for Making Air Transportation Security Decisions.

  &lt;td class=&quot;diff-context diff-side-deleted&quot;&gt;&lt;div&gt;Estimation of the expected benefits of security measures is the second step. These benefits basically depend on the magnitude of the risk of a security threat (crime and terrorism) and the reduction in these expected losses (in economic terms). Hence, if the risk of a certain event is low, the potential benefits of improved security will also be low, no matter how expensive this measure is&amp;lt;ref&amp;gt;Or, the other way around: If a certain risk is very high, even a small risk reduction will generate substantial benefits.&amp;lt;/ref&amp;gt;. Since both the magnitudes of risks and the impact of security measures are difficult to estimate, it can be helpful to think in terms of how much a certain security measure should reduce the risk of a security threat to be cost-effective. For example, if surveillance measures in a particular urban area cost 10 million euro per year, and the expected losses of crime and terrorism in that area are 100 million euro per year, a 10 percent reduction in risk would justify the cost of this surveillance measure (assuming it is realised by this particular security option, and not different measures or circumstances). To do this, economists use different sets of assumptions and parameters about criminal and terrorist behaviour, crime statistics, risk assumptions, etc. enabling them to analyse the cost-effectiveness of a single or multiple security measures&amp;lt;ref&amp;gt;In practice, serious targets like transportation hubs or utility objects are hardly ever protected by a single security measure. See e.g., Jackson &#039;&#039;et al&#039;&#039;  (2012): Efficient Aviation Security. Strengthening the Analytic Foundation for Making Air Transportation Security Decisions.

These benefits basically depend on the magnitude of the risk of a security threat (crime and terrorism) and the reduction in these expected losses (in economic terms). Hence, if the risk of a certain event is low, the potential benefits of improved security will also be low, no matter how expensive this measure is&amp;lt;ref&amp;gt;Or, the other way around: If a certain risk is very high, even a small risk reduction will generate substantial benefits&amp;lt;/ref&amp;gt;. Since both the magnitudes of risks and the impact of security measures are difficult to estimate, it can be helpful to think in terms of how much a certain security measure should reduce the risk of a security threat to be cost-effective.
