Provide advice and support to clients on how to configure their log sources to send useful events to the SIEM. Work with client IT personnel – where required – to configure their log sources. Verify log sources feed into the SIEM correctly.
  • Troubleshoot and resolve technical issues impacting event flow from log sources to SIEM. Identify and resolve technical and performance issues affecting log collection.
  • Assess clients’ log coverage and identify gaps where it would be useful to onboard security events to improve coverage and detection capability.
