About this role
Protecting RHB against advanced cyber threats through proactive detection engineering, continuous threat hunting, and rapid incident response. Design and implement detection logic, lead hunts for known & unknown threats, and respond to incidents to contain and eradicate malicious activity across on-premises and cloud environments. This role will be technical SME for cyber security related matters.
Key Responsibilities: Solution Engineering
• Maintaining of security solution including Splunk, Imperva and etc. (Task including compliance to patch and obsolescence framework requirement, UAMR etc.) • Ensure events / logs from all relavant devices are sending to SIEM solution in a complete and accurate manner • To produce monthly SIEM system health report (completeness and accurate) • Assist in the design, evaluation, and implementation of new security technologies
Proactive Threat Hunting
• Perform hypothesis-driven threat hunts using advanced analytics, behavioral patterns, and threat intelligence. • Analyze various logs sources to identify anomalous activities, potential compromises, and previously undetected threats • Develop and refine hunting methodologies and detection logic to improve visibility and coverage • Identify gaps in IT infrastructure by mimicking an attacker s behaviors and responses • Document and communicate hunting results, including risk impact and recommended mitigations.
Detection & Response
• Continuously develop, finetune and review SIEM use cases based on Mitre Attack framework and current threat landscape • Contribute to the continuous improvement of detection capabilities and automation processes. • Correlate data from multiple sources (network logs, endpoint telemetry, cloud environments) to detect stealthy or novel attacks. • Develop dashboards and reports to identify potential threats, suspicious/anomalous activity, internal threat landscape, etc.
Digital Forensic
• Lead response and investigation efforts into advanced/targeted attacks • Lead in incident response activities such as digital forensic, host triage and retrieval, malware analysis, remote system analysis, end-user interviews, and remediation efforts • Compile detailed investigation and analysis reports for internal SOC consumption and delivery to management • Provide expert analytic investigative support of large scale and complex security incidents • Perform Root Cause Analysis of security incidents for further enhancement of alert catalog
Incident Response
• Lead or support security incident investigations from detection through containment, eradication and recovery • Perform deep-dive and forensics analysis during ongoing or post-incident reviews. • Develop post-incident reports and lessons learned to drive improvements in detection and response capabilities
Research and Continuous Improvement
• Stay up to date with emerging threats, attacker behaviors, and cybersecurity trends. • Develop and maintain custom scripts and tools to automate hunting and analysis tasks (e.g., Python, PowerShell, or Bash). • Knowledge sharing through internal training sessions and threat briefings • Mentor junior analysts and engineers on threat analysis methodologies
