The Role of Custom Scripting in APT Incident Response

Abstract

Advanced Persistent Threats (APTs) present complex challenges by employing covert and sophisticated techniques that evade traditional security measures. This study investigates the role of custom scripting in improving incident response capabilities based on interviews with cybersecurity professionals in various sectors. The findings demonstrate that custom scripts bridge critical gaps left by commercial and open-source tools, providing the flexibility and precision to detect and mitigate complex threats. Despite their effectiveness, custom scripts require specialized skills and resources, creating a disparity between large and small organizations in their ability to combat advanced threats. This paper advocates integrating custom scripting within standardized incident management and response, and helping commercial tools address these challenges. Recommendations include targeted training, investment in skill development, and establishing robust policies for script usage and maintenance. Future research should explore the integration of emerging technologies such as artificial intelligence (AI) and machine learning to further enhance scripting capabilities in cybersecurity operations.
