Integrate logs from operating systems, network devices, applications, security tools, and infrastructure platforms to improve enterprise security visibility.
Monitor and troubleshoot log ingestion failures, parsing errors, data quality issues, and system performance concerns.
Collaborate with system owners and cybersecurity teams to ensure logging and auditing practices align with NIST SP 800-53 Audit and Accountability (AU) controls across multiple classified enclaves.
Identify gaps in logging coverage and implement enhancements to improve threat detection, incident investigation, and security monitoring.
