Security Platform Integration

Splunk Integration

Integrate with Splunk for centralized security monitoring:

splunk-integration.conf

[kestrel_findings]
SHOULD_LINEMERGE = false
TRUNCATE = 10000
TIME_PREFIX = \"timestamp\":\"
TIME_FORMAT = %Y-%m-%dT%H:%M:%S
KV_MODE = json
category = Application
description = Kestrel Security Findings

Splunk Universal Forwarder Configuration:

# Monitor Kestrel JSON reports
./splunk add monitor /var/log/kestrel/reports/ \
  -sourcetype kestrel_findings \
  -index security

# Send to Splunk via API
curl -k https://splunk.company.com:8088/services/collector \
  -H "Authorization: Splunk $SPLUNK_HEC_TOKEN" \
  -d @kestrel-report.json

Splunk Search Queries:

# Critical findings trend
index=security sourcetype=kestrel_findings severity=critical
| timechart span=1d count by rule_id

# Compliance score over time
index=security sourcetype=kestrel_findings
| eval compliance_score=round((compliant_requirements/total_requirements)*100, 2)
| timechart span=1d avg(compliance_score)

# Top vulnerable repositories
index=security sourcetype=kestrel_findings
| stats count by repository, severity
| sort -count

IBM QRadar Integration

Configure Kestrel findings for QRadar SIEM:

qradar-dsm.xml

<?xml version="1.0" encoding="UTF-8"?>
<device-extension xmlns="event_parsing/device_extension">
    <pattern id="Kestrel_Finding">
        <![CDATA[\"severity\":\"(?P<severity>\w+)\".*\"rule_id\":\"(?P<rule_id>[^"]+)\".*\"file\":\"(?P<filename>[^"]+)\"]]>
    </pattern>
    
    <event-match-single pattern-id="Kestrel_Finding">
        <event>
            <custom-property name="KestrelSeverity" property-name="severity"/>
            <custom-property name="KestrelRuleID" property-name="rule_id"/>
            <custom-property name="KestrelFile" property-name="filename"/>
        </event>
    </event-match-single>
</device-extension>

Elastic Stack Integration

Send findings to Elasticsearch:

logstash.conf

input {
  file {
    path => "/var/log/kestrel/*.json"
    start_position => "beginning"
    codec => "json"
    type => "kestrel"
  }
}

filter {
  if [type] == "kestrel" {
    # Parse severity as numeric for sorting
    if [severity] == "critical" {
      mutate { add_field => { "severity_numeric" => 4 } }
    } else if [severity] == "high" {
      mutate { add_field => { "severity_numeric" => 3 } }
    } else if [severity] == "medium" {
      mutate { add_field => { "severity_numeric" => 2 } }
    } else {
      mutate { add_field => { "severity_numeric" => 1 } }
    }
    
    # Extract repository from file path
    grok {
      match => { "file" => "/repos/(?<repository>[^/]+)/" }
    }
  }
}

output {
  if [type] == "kestrel" {
    elasticsearch {
      hosts => ["elasticsearch:9200"]
      index => "kestrel-findings-%{+YYYY.MM.dd}"
    }
  }
}
