  • Maintain detailed documentation of SIEM use cases, generating reports on their performance and effectiveness.
  • Work closely with stakeholders, including SOC analysts, incident responders, and IT teams, to ensure use cases meet their needs, collaborating with SIEM vendors to troubleshoot issues and implement new features.
  • Innovate and experiment with new use case ideas to enhance the SIEM's detection capabilities, designing and developing automated workflows to address common security operations tasks and incidents.
  • You will write and maintain scripts (e.g., Python, PowerShell) to support automation tasks, creating and implementing playbooks that automate the response to security incidents.
  • Develop use cases for automation based on common incident scenarios and threat patterns, automating the enrichment of security alerts with contextual information to improve decision-making.
  • Integrate various security tools (e.g., SIEM, EDR, ITSM (Service Now), firewalls, Threat intelligence platforms) with the SOAR platform, continuously optimising automated workflows to reduce false positives and enhance detection accuracy.
  • Tune the performance of automated workflows to ensure they operate efficiently and effectively, establishing a feedback loop with security teams to gather input on automation performance and make necessary adjustments.

Key Requirements:

  • Proficiency with proposed SOAR and SIEM solutions
  • Experience in configuring, managing, and optimising SOAR and SIEM platforms
  • Strong skills in scripting languages (e.g., Python, PowerShell, JavaScript) for developing automation scripts
  • Experience in writing and maintaining scripts to automate security tasks and processes
  • Experience in utilising RESTful APIs to enable communication between different security tools
  • Experience in converting MITRE TTPs to Misuse cases for better detection and response
