Sometimes security management reminds me of Marvel Studios’ Avengers: Infinity War. The purpose of security management is to ensure the safety of the staff within the organization. In the film, the titular characters attempt to protect the infinity stones from the villain, Thanos. The Avengers had to employ different methods of security to protect the stones.
The characters protected themselves in Wakana by a forcefield that would serve up a shock to anyone who attempted to break through. Individuals used the same technology as personal shields for any enemies who broke through. However, this security was tested with Thanos’ army.
Even with all this protection, Thanos’ army was determined to get the stone, so singularly focused that they threw themselves at the forcefield—sacrificing themselves in the process. Their determination and brute force allowed some of the army through the protective barrier. The heroes had to change their method of security to protect the stone.
Just like the movie, we like to feel that someone is working to keep us safe.
