5. Conclusion and Discussion

This study comprehensively examines the role of red teaming in enhancing cybersecurity within Indonesia's regulated industries, focusing on the banking and fintech sectors. Our research reveals that red teaming is critical for identifying vulnerabilities, improving regulatory compliance, and boosting organizational resilience against complex cyber threats. The findings of this study have significant implications for practitioners, policymakers, and researchers in the cybersecurity field, especially within Indonesia's rapidly evolving digital landscape.

5.1 The critical role of red teaming in Indonesian cybersecurity

Our analysis demonstrates that red teaming plays a pivotal role in three key areas:

  • Vulnerability identification: Red team exercises prove exceptionally effective in uncovering hidden weaknesses in organizational cybersecurity defenses that traditional audits often overlook. In the Indonesian context, these exercises were particularly adept at identifying vulnerabilities related to legacy systems integration, a common issue in the country's rapidly digitalizing banking sector. They also exposed security gaps in mobile banking applications, which are gaining immense popularity in Indonesia but often lack robust security measures. Furthermore, red teaming revealed significant vulnerabilities in employee awareness and susceptibility to social engineering attacks, a critical factor given Indonesia's diverse workforce and varying levels of cybersecurity education.
  • Regulatory compliance enhancement: Our study demonstrates that red teaming significantly improves compliance with Indonesia's evolving cybersecurity regulations. Specifically, it aids in meeting the requirements outlined in OJK Regulation No. 13/POJK.02/2018 on Digital Financial Innovation and Bank Indonesia Regulation No. 18/40/PBI/2016 on Payment Transaction Processing. Red team exercises provide concrete evidence of security measures' effectiveness, facilitating more comprehensive compliance reporting and helping organizations stay ahead of regulatory expectations in a rapidly changing digital environment.
  • Organizational resilience boosting: By simulating advanced persistent threats (APTs) and nation-state-level attacks, red teaming prepares Indonesian organizations for high-level cyber threats. This is particularly crucial given Indonesia's geopolitical position and the increasing sophistication of cyber attacks targeting Southeast Asian financial institutions. Our findings indicate that organizations regularly conduct red team exercises, demonstrate markedly improved incident response times, and are better equipped to handle complex, multi-vector attacks.

5.2 Innovations and contributions of the study

This research makes several significant contributions to the field of cybersecurity, particularly in the Indonesian context:

  • Tailored red teaming framework: We developed a comprehensive framework specifically designed for the Indonesian regulatory environment. This framework aligns red team objectives with Indonesia's unique cybersecurity challenges, such as the rapid adoption of digital banking in rural areas and the need for robust security in an increasingly mobile-first market. It incorporates cultural nuances that affect cybersecurity practices in Indonesian organizations, such as the tendency towards hierarchical decision-making structures and the importance of saving face. Additionally, our framework provides a structured approach to reporting red team findings that directly address regulatory requirements, facilitating clearer communication between security teams, management, and regulatory bodies.
  • Gap analysis and enhancement proposals: Our research identified critical gaps between current red teaming practices and regulatory expectations in Indonesia. Key findings include a lack of emphasis on testing incident response capabilities, which are crucial in the Indonesian context due to the country's vulnerability to natural disasters and their potential impact on digital infrastructure. We also found insufficient focus on third-party risk assessment, a significant concern given the growing fintech ecosystem in Indonesia and the interconnectedness of financial services. To address these gaps, we propose incorporating disaster recovery scenarios into red team exercises, extending red team scope to include critical third-party providers, and developing a continuous feedback loop between red team findings and security strategy development. These enhancements not only align with but also surpass current regulatory standards, potentially driving the development of stronger cybersecurity regulations in Indonesia.
