| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Key measures undertaken by the Bank to mitigate information security related risks: We continue to enhance its information security posture through a robust, multi layered control environment designed to safeguard customer data and ensure secure digital operations. This is supported by Board approved Information Security and Cyber Security policies, with strategic oversight provided by the Information Technology Strategy Committee and the Information Security Committee. The committees review key risks, monitor emerging threats, and ensure alignment with regulatory expectations. Our advanced AI/ML enabled Cyber Security Operations Centre (“CSOC”) provides round the clock monitoring of infrastructure, network traffic and applications. Enriched threat intelligence feeds and machine learning–driven analytics enable early detection of anomalies and improved correlation of suspicious activities, while behavioral modelling further enhances incident identification and response. The Attack Surface Management (ASM) programme further mitigates risk by continuously identifying and remediating exposures across internal and external digital assets, supported by vulnerability assessments and penetration testing. Further, our security controls across networks, applications and endpoints include anti malware technologies, Intrusion Detection and Prevention Systems (IDS/IPS), micro segmentation, and enterprise wide Data Loss Prevention (DLP) safeguards. Cloud and data security measures are strengthened through Cloud Security Posture Management (CSPM), Cloud Infrastructure Entitlement Management (CIEM) and Cloud Workload Protection Platform (CWPP) to ensure secure cloud configurations, entitlement governance, workload protection, and sensitive data oversight across hybrid environments. Strong access controls form a key part of the Bank’s security framework, with Identity and Access Management (IAM), Privileged Access Management (PAM), authentication methods, and periodic access reviews enforcing least privilege principles and preventing unauthorized access. Periodic adversarial exercises are carried out by the bank’s Red Team to assess system resilience, uncover vulnerabilities, and validate detection and response controls. Activities include red team operations, breach simulations, and targeted assessments of key security technologies, aligned to the MITRE ATT&CK framework for testing. To mitigate phishing, impersonation, and customer facing cyber fraud risks, the Bank continuously monitors for fraudulent domains and phishing campaigns, initiating rapid takedown actions when required. These initiatives are reinforced by regular employee training, cyber drills, and awareness programs that build a strong culture of cybersecurity across the organization. This layered approach helps contain threats, limit their spread across the environment, and preserve business continuity by ensuring that endpoints remain consistently protected and actively monitored. Collectively, these measures demonstrate our ongoing commitment to mitigating information security risks and maintaining a secure, resilient, and trusted digital banking environment. Extended Detection and Response (XDR) / Malware Programme Vulnerability management AI-for-security security-of-AI Patch management: Penetration testing: Network security Our intrusion detection and prevention systems (IDS/IPS) provide deep, real time inspection of network traffic to identify, alert, and block malicious activity. Regular signature updates and behavioral analytics enhance detection accuracy and improve responsiveness to new threats, attacker techniques, and anomalous patterns. Configured with automated alerting and threshold based triggers, these systems support proactive monitoring and rapid containment, strengthening the Bank’s ability to detect, prevent, and mitigate potential security breaches. Together, these integrated network security controls form a robust, multi layered defense model that aligns with global best practices and ensures strong protection across our digital ecosystem.
