Security theater is the practice of organizations or security teams implementing publicized or superficial measurements that create an atmosphere of safety that may only achieve the appearance of heightened security. While actual security processes can be measured based on the probability of various risks and how equipped a group is to handle them, security theater is based on a psychological feeling. The term was first coined by the computer security expert, Bruce Schneier, and has since been adapted to describe a variety of scenarios.
Without any mathematical basis, individuals can have psychological reactions to their assessment of potential risks in their lives and circumstances. In many situations, these can even be far removed from the actual calculated probability of these risks. An individual might feel more strongly at risk of certain kinds of threats than others based on the information they consume about those kinds of risks and their personal biases about them. Security theater is the purposeful attempt to create more positive feelings of safety, even in the complete absence of implementing measures that actually improve safety.
The psychology of security theater measures can have positive or adverse effects. They may have a positive effect by helping to thwart the spread of unnecessary fear, but at the same time a false feeling of security could make people less on their guard than they would normally be, actually lowering their security.
Examples of security theater
Some examples of measures that are considered security theater rather than authentic security include:
- Security guards whose guns contain blanks.
- Elaborate airport security systems that give an impression of being more thorough than they actually are, such as random individual searches.
- Dummy security cameras that do not capture or broadcast actual footage.
- Computer systems that hide their system features to make them seem less vulnerable to attacks.
- Password strength policies that are not reinforced by IT staff.
- Building access that is granted by an identification badge.
- Tamper-evident seals on pill bottles or packaged goods.
Some of these measures may have a slight benefit to security, but ultimately security theater measures are more about making individuals feel better. In each of these instances, the security measure can be fairly easily circumvented. For example, a criminal could make a copy of an identification badge. However, in general the public still feels better having a superficial security barrier in place because it may still improve the probability that the people involved will stay safe.
