  • Q: What is the 'Project Planning' phase's most critical output for a SIEM deployment?
    A: A clear definition of the specific problems the SIEM is solving (e.g., compliance vs. threat detection) to prevent scope creep.
  • Q: How does 'Log Normalization' directly impact detection logic?
    A: It enables correlation rules to work across disparate devices (e.g., Cisco firewall and Windows server) by standardizing fields like IP and Username.
  • Q: What is the operational risk of failing to 'Archive' SIEM data?
    A: Performance degradation of the active database, leading to slow queries and missed alerts due to ingestion lag.
  • Q: Why is 'User Account Management' within the SIEM critical?
    A: To ensure that access to sensitive log data is restricted and auditable, preventing insider misuse of the security tool itself.
  • Q: How does the 'Lessons Learned' loop improve SIEM content?
    A: It uses data from actual incidents to tune existing rules and create new ones, ensuring the SIEM evolves with the threat landscape.
  • Q: What implies the need for 'Emergency Content Development'?
    A: The realization that new threats (zero-days) require immediate, ad-hoc rules that may bypass standard change control for speed.
  • Q: What is the strategic value of 'Time Synchronization' for the SIEM?
    A: It is the fundamental requirement for correlation; without it, the sequence of events cannot be determined, making attack reconstruction impossible.
  • Q: How does the document suggest managing 'Agent Updates'?
    A: By anticipating the need for updates as part of the application lifecycle, ensuring visibility isn't lost when source systems change.
  • Q: What is the 'Steering Committee' role in SIEM success?
    A: To provide the political cover and authority needed to force system owners to provide logs and support the SIEM initiative.
  • Q: How does 'Data Classification' align with SIEM design?
    A: It helps determine which logs must be retained for long periods (compliance) versus which can be dropped quickly (operational noise).
