Automation Bias and Complacency in Security Operation Centers

The volume and complexity of alerts that security operation center (SOC) analysts must manage necessitate automation. Increased automation in SOCs amplifies the risk of automation bias and complacency whereby security analysts become over-reliant on automation, failing to seek confirmatory or contradictory information. To identify automation characteristics that assist in the mitigation of automation bias and complacency, we investigated the current and proposed application areas of automation in SOCs and discussed its implications for security analysts. A scoping review of 599 articles from four databases was conducted. The final 48 articles were reviewed by two researchers for quality control and were imported into NVivo14. Thematic analysis was performed, and the use of automation throughout the incident response lifecycle was recognized, predominantly in the detection and response phases. Artificial intelligence and machine learning solutions are increasingly prominent in SOCs, yet support for the human-in-the-loop component is evident. The research culminates by contributing the SOC Automation Implementation Guidelines (SAIG), comprising functional and non-functional requirements for SOC automation tools that, if implemented, permit a mutually beneficial relationship between security analysts and intelligent machines. This is of practical value to human automation researchers and SOCs striving to optimize processes. Theoretically, a continued understanding of automation bias and its components is achieved.
