- Collection methods (agent-based, agentless, API-based, syslog)
- Log format standardization (CEF, JSON, syslog RFC 5424)

- Retention periods mapped to compliance requirements (ISO 27001 A.8.15, SOC 2 CC7.2, GDPR Art. 5(1)(e))
- Storage tiering (hot/warm/cold) with cost optimization
- Integrity protection for log data (hashing, write-once storage)

Our compliance scope includes [ISO 27001/SOC 2/NIST CSF/GDPR]. Output as architecture document with data flow diagram description.

Compare SIEM architecture options for a [organization size] organization with [cloud environment]. Evaluate:
- Cloud-native SIEM (Microsoft Sentinel, Chronicle, AWS Security Lake + OpenSearch)
- Commercial SIEM (Splunk, QRadar, LogRhythm)
- Open-source SIEM (Wazuh, Elastic Security, Graylog)

For each option, assess: log ingestion capacity, detection rule capabilities, compliance reporting, retention management, integration ecosystem, and total cost of ownership. Our primary frameworks are [list frameworks].

Recommend an architecture that satisfies ISO 27001 A.8.15-A.8.16 and SOC 2 CC7.1-CC7.3 requirements.

Create a MITRE ATT&CK detection coverage matrix for our SIEM deployment covering [log sources available]. For each ATT&CK tactic:
- Map available log sources to detectable techniques
- Identify coverage gaps where we lack visibility
- Prioritize gap remediation based on threat intelligence relevant to [industry]
- Cross-reference detection capabilities to ISO 27001 A.8.16 and NIST DE.CM (Continuous Monitoring) requirements

Output as a matrix with coverage status (Detected/Partial/Gap) and remediation priority.

Generate SIEM detection rules for [SIEM platform] that address the following ISO 27001 and SOC 2 controls:

1. A.5.17 / CC6.1 - Authentication information: Detect brute force attacks, credential stuffing, password spraying

3. A.8.16 / CC7.2 - Monitoring activities: Detect log source failures, SIEM health anomalies, collection gaps
4. A.5.7 / CC3.2 - Threat intelligence: Detect connections to known malicious IPs, domains, and file hashes
5. A.8.12 / CC6.8 - Data leakage prevention: Detect unusual data exfiltration patterns, large file transfers, unauthorized cloud storage uploads

For each rule, provide: rule logic (query/SPL/KQL), threshold values, severity rating, false positive tuning guidance, and the specific control it satisfies.

Output in [SIEM query language] format.

Design alert correlation rules for [SIEM platform] that reduce alert fatigue while maintaining detection fidelity. Include:
- Multi-stage attack detection (reconnaissance → exploitation → lateral movement → exfiltration)

- Asset criticality-weighted alerting (higher severity for crown jewel assets)
- Time-window correlation (related events within configurable periods)
- Suppression rules for known-good patterns (maintenance windows, authorized scanners)
- Alert enrichment with threat intelligence and asset context
- Escalation triggers for correlated incidents

Map correlation rules to SOC 2 CC7.2 (anomaly detection) and NIST DE.AE (Security event analysis). Define tuning procedures and false positive review cadence.
