4. Incident Response Phases

4.1 Phase 1: Preparation

Before an Incident

  1. Maintain incident response tools:

    Terminal window
    # Incident response toolkit
    /opt/security/ir-toolkit/
    ├── forensics/
    │   ├── memory-capture.sh
    │   ├── disk-image.sh
    │   └── log-collection.sh
    ├── containment/
    │   ├── isolate-server.sh
    │   ├── block-ip.sh
    │   └── lock-accounts.sh
    └── recovery/
        ├── restore-backup.sh
        ├── rotate-credentials.sh
        └── verify-integrity.sh

  2. Ensure backup integrity:

    Terminal window
    # Verify backups daily
    heliosdb-backup verify --all
    heliosdb-backup test-restore --latest

  3. Review and update procedures:

    • Quarterly tabletop exercises
    • Annual full-scale drill
    • Update contact information
    • Test communication channels

  4. Maintain monitoring and alerting:

    monitoring/alerts.yaml
    critical_alerts:
      - failed_auth_threshold: 10/5min
      - privilege_escalation: immediate
      - encryption_key_access: immediate
      - unusual_query_patterns: 5min
      - data_export_large: immediate

4.2 Phase 2: Detection and Analysis

Detection Methods

  1. Automated Monitoring:

    Terminal window
    # Security monitoring dashboard
    heliosdb-monitor security-dashboard
    

    # Real-time alerts
    tail -f /var/log/heliosdb/security-alerts.log

  2. Manual Detection:

    • User reports
    • Security scan results
    • Audit log review
    • Anomaly detection

Initial Analysis

  1. Triage (< 5 minutes):

    # Quick assessment script
    #!/bin/bash
    

    echo "=== Incident Triage ==="
    echo "Timestamp: $(date)"
    

    # Check active connections
    echo "\n=== Active Connections ==="
    heliosdb-cli list-connections
    

    # Check recent auth failures
    echo "\n=== Recent Failed Logins ==="
    heliosdb-cli audit-query --event=auth_failure --since="1 hour"
    

    # Check privilege changes
    echo "\n=== Recent Privilege Changes ==="
    heliosdb-cli audit-query --event=privilege_change --since="1 hour"
    

    # Check unusual queries
    echo "\n=== Suspicious Queries ==="
    heliosdb-cli audit-query --pattern="DROP|DELETE|UPDATE" --since="1 hour"

  2. Determine Severity:

    • Impact assessment
    • Scope determination
    • Classification (P0-P3)
    • Escalation decision

  3. Document Everything:

    Terminal window
    # Create incident log
    INCIDENT_ID="INC-$(date +%Y%m%d-%H%M%S)"
    mkdir -p /secure/incidents/${INCIDENT_ID}
    

    # Start incident log
    cat > /secure/incidents/${INCIDENT_ID}/incident.log <<EOF
    Incident ID: ${INCIDENT_ID}
    Detected: $(date)
    Detected By: ${USER}
    Initial Classification: P0
    Description: Suspected data breach - unusual data export activity
    EOF

4.3 Phase 3: Containment

Short-term Containment (< 30 minutes)

  1. Isolate Affected Systems:

    # Network isolation script
    #!/bin/bash
    

    INCIDENT_ID=$1
    AFFECTED_SERVER=$2
    

    # Block incoming connections
    iptables -A INPUT -p tcp --dport 5432 -j DROP
    

    # Allow only IR team access
    iptables -I INPUT -s 10.0.100.0/24 -p tcp --dport 5432 -j ACCEPT
    

    # Log containment action
    echo "$(date) - Network isolation applied to ${AFFECTED_SERVER}" \
        >> /secure/incidents/${INCIDENT_ID}/actions.log

  2. Preserve Evidence:

    # Evidence collection script
    #!/bin/bash
    

    INCIDENT_ID=$1
    EVIDENCE_DIR="/secure/incidents/${INCIDENT_ID}/evidence"
    mkdir -p ${EVIDENCE_DIR}
    

    # Capture memory dump
    echo "Capturing memory dump..."
    dd if=/dev/mem of=${EVIDENCE_DIR}/memory.dump
    

    # Copy audit logs
    echo "Preserving audit logs..."
    cp -a /var/log/heliosdb/audit* ${EVIDENCE_DIR}/
    

    # Export current connections
    echo "Capturing connection state..."
    heliosdb-cli list-connections --detailed > ${EVIDENCE_DIR}/connections.txt
    

    # Query log snapshot
    echo "Capturing query log..."
    heliosdb-cli export-query-log --last=24h > ${EVIDENCE_DIR}/queries.log
    

    # Compute checksums
    cd ${EVIDENCE_DIR}
    sha256sum * > checksums.txt

  3. Lock Compromised Accounts:

    Terminal window
    # Lock user accounts
    heliosdb-cli lock-user suspicious_user
    heliosdb-cli revoke-all-sessions suspicious_user
    

    # Log action
    echo "$(date) - Locked account: suspicious_user" \
        >> /secure/incidents/${INCIDENT_ID}/actions.log

Long-term Containment

  1. Deploy Patches:

    • Apply security updates

    • Harden configurations

  2. Rotate Credentials:

    Terminal window
    # Emergency credential rotation
    heliosdb-cli rotate-all-passwords --force
    heliosdb-cli rotate-all-keys --emergency
    

    # Generate new API keys
    heliosdb-cli regenerate-api-keys

  3. Enhanced Monitoring:

    Terminal window
    # Enable verbose auditing
    heliosdb-cli set audit_level VERBOSE
    

    # Add temporary alerting rules
    heliosdb-cli add-alert --condition="ANY suspicious activity" \
        --action="page security-oncall"

4.4 Phase 4: Eradication

  1. Remove Malicious Artifacts:

    Terminal window
    # Search for backdoors
    heliosdb-cli scan-for-backdoors
    

    # Remove malicious stored procedures
    heliosdb-cli list-procedures --suspicious
    heliosdb-cli drop-procedure malicious_proc
    

    # Clean up malicious data
    heliosdb-cli sanitize-data --table=compromised_table

  2. Fix Vulnerabilities:

    • Patch exploited vulnerabilities
    • Reconfigure security settings
    • Update security policies

  3. Verify System Integrity:

    Terminal window
    # Integrity verification
    heliosdb-cli verify-system-integrity
    heliosdb-cli verify-data-integrity --all-tables
    heliosdb-cli verify-encryption-keys

4.5 Phase 5: Recovery

  1. Restore from Clean Backup (if needed):

    # Recovery script
    #!/bin/bash
    

    INCIDENT_ID=$1
    BACKUP_DATE=$2
    

    # Stop database
    systemctl stop heliosdb
    

    # Backup current state (for forensics)
    tar -czf /secure/incidents/${INCIDENT_ID}/pre-restore-state.tar.gz \
        /var/lib/heliosdb
    

    # Restore from clean backup
    heliosdb-backup restore --date=${BACKUP_DATE} --verify
    

    # Rotate all keys
    heliosdb-cli rotate-all-keys --force
    

    # Start database
    systemctl start heliosdb
    

    # Verify recovery
    heliosdb-cli health-check
    heliosdb-cli verify-data-integrity

  2. Gradual Service Restoration:

    Terminal window
    # Phased restoration
    

    # Phase 1: Internal testing
    heliosdb-cli set maintenance_mode on
    heliosdb-cli allow-ip 10.0.100.0/24  # IR team only
    

    # Phase 2: Limited users
