Final answer:
Security breaches occur due to multiple factors including human error, management mishaps, insider threats, and poor working conditions, all of which can cause significant damage such as identity and financial theft, as well as threats to national security.
Step-by-step explanation:
Security breaches occur for various reasons, including human error, mismanagement, malicious insiders, and inadequate security measures. For instance, a study by Bruno & Abrahão (2012) revealed that an increased volume of decisions can lead to more errors by operators, such as falsely identifying security breaches, especially when under cognitive strain. The infamous Target data breach of 2013 exemplifies the consequences of such errors, where signals of a breach were misinterpreted by security personnel.
Excessive paperwork, poor work conditions, and overload are additional factors that might contribute to security issues. Furthermore, feelings of unfair treatment or injustice among workers can incite incidents such as theft, as demonstrated by Greenberg (1993), and this is applicable in the context of data security as well. The importance of addressing these problems is highlighted by the significant impacts of data breaches, including identity theft, financial theft, threats to national security, and the general chaos and financial costs they entail.
