System Administrators Prefer Command Line Interfaces, Don't They? An Exploratory Study of Firewall Interfaces
Artem Voronkov, Leonardo A. Martucci, Stefan Lindskog

TL;DR
This study investigates the preferences and actual usage of GUI and CLI interfaces among firewall system administrators, revealing a preference for GUIs despite the common assumption that CLIs are favored.
Contribution
It provides empirical data on interface preferences and usage patterns of system administrators, along with design recommendations for firewall interfaces.
Findings
60% of administrators prefer GUIs over CLIs
32% of administrators prefer CLIs for firewall management
Identified strengths and limitations of each interface type
Abstract
A graphical user interface (GUI) represents the most common option for interacting with computer systems. However, according to the literature system administrators often favor command line interfaces (CLIs). The goal of our work is to investigate which interfaces system administrators prefer, and which they actually utilize in their daily tasks. We collected experiences and opinions from 300 system administrators with the help of an online survey. All our respondents are system administrators, who work or have worked with firewalls. Our results show that only 32% of the respondents prefer CLIs for managing firewalls, while the corresponding figure is 60% for GUIs. We report the mentioned strengths and limitations of each interface and the tasks for which they are utilized by the system administrators. Based on these results, we provide design recommendations for firewall interfaces.
