## Detection & Triage

### Detection Methods

#### Automated Alerts

**Prometheus Alerts**:
```yaml
# prometheus/alerts.yml
groups:
  - name: security_incidents
    rules:
      - alert: CriticalSecurityViolation
        expr: |
          sum(rate(security_violations_total{severity="critical"}[5m])) > 0
        for: 0m
        labels:
          severity: critical
          priority: P0
        annotations:
          summary: "Critical security violation detected"
          description: "{{ $value }} critical security violations in last 5 minutes"

      - alert: HighRateOfAuthFailures
        expr: |
          sum(rate(authentication_failures_total[5m])) > 20
        for: 5m
        labels:
          severity: warning
          priority: P1
        annotations:
          summary: "High rate of authentication failures"
          description: "{{ $value }} auth failures per second"
```

**Audit Log Monitoring**:
```bash
# Monitor critical events in real-time
tail -f /var/log/memory/audit.log | grep --line-buffered "CRITICAL" | \
  while read line; do
    # Send alert (Slack, PagerDuty, etc.)
    send_alert "Critical security event: $line"
  done
```

#### Manual Detection

**Daily Security Review**:
```bash
#!/bin/bash
# daily_security_review.sh

echo "=== Security Review for $(date +%Y-%m-%d) ==="

# 1. Critical events
echo "Critical events:"
grep "CRITICAL" /var/log/memory/audit.log | \
  grep "$(date +%Y-%m-%d)" | \
  jq -r '.event_type + " | " + .actor + " | " + .details'

# 2. Security violations
echo "Security violations:"
grep "security_violation" /var/log/memory/audit.log | \
  grep "$(date +%Y-%m-%d)" | wc -l

# 3. Access denied events
echo "Access denied events:"
grep "access_denied" /var/log/memory/audit.log | \
  grep "$(date +%Y-%m-%d)" | wc -l

# 4. Rate limit violations
echo "Rate limit violations:"
grep "rate_limit_violation" /var/log/memory/audit.log | \
  grep "$(date +%Y-%m-%d)" | wc -l

# 5. Authentication failures
echo "Authentication failures:"
grep "auth_failure" /var/log/memory/audit.log | \
  grep "$(date +%Y-%m-%d)" | wc -l
```

### Triage Process

#### Initial Assessment (5-10 minutes)

```bash
# 1. Check system status
curl http://localhost:8080/health

# 2. Check recent critical events
grep "CRITICAL\|ERROR" /var/log/memory/audit.log | tail -50

# 3. Check rate limit statistics
curl http://localhost:8080/metrics | grep -E "(rate_limit|security|auth)"

# 4. Check service logs
journalctl -u memory-service -n 100 --since "5 minutes ago"

# 5. Check system resources
top -bn1 | head -20
df -h
free -h
```

#### Determine Severity

| Indicator | P0 | P1 | P2 | P3 |
|-----------|----|----|----|-----|
| Data breach | ✓ | | | |
| Complete outage | ✓ | | | |
| Active attack | ✓ | ✓ | | |
| Service degraded | ✓ | ✓ | ✓ | |
| Security violation | ✓ | ✓ | ✓ | |
| Configuration issue | | | ✓ | ✓ |
| Anomaly detected | | | ✓ | ✓ |

#### Assign Priority

```bash
# Example triage script
ASSIGN_PRIORITY() {
    local severity=$1
    local impact=$2
    local urgency=$3

    if [[ "$severity" == "critical" ]] || [[ "$impact" == "complete" ]]; then
        echo "P0"
    elif [[ "$severity" == "high" ]] || [[ "$impact" == "significant" ]]; then
        echo "P1"
    elif [[ "$severity" == "medium" ]] || [[ "$impact" == "limited" ]]; then
        echo "P2"
    else
        echo "P3"
    fi
}
```

## Containment Strategies

### Immediate Actions (First 15 Minutes)

#### For P0 - Critical Incidents

```bash
# 1. EMERGENCY SHUTDOWN (if data breach in progress)
sudo systemctl stop memory-service

# 2. Preserve evidence
sudo cp /var/log/memory/audit.log /var/log/memory/audit.log.emergency.$(date +%Y%m%d%H%M%S)
sudo cp /var/log/memory/*.log /tmp/emergency_backup/

# 3. Enable critical-only audit logging
export MEMORY_AUDIT_LEVEL=critical
export MEMORY_AUDIT_OUTPUT=stderr

# 4. Block all external access
sudo ufw deny in from any to any port 8080

# 5. Notify response team
send_alert "P0 CRITICAL: Service stopped, emergency containment activated"
```

#### For P1 - High Incidents

```bash
# 1. Enable strict rate limiting
export MCP_RATE_LIMIT_READ_RPS=10
export MCP_RATE_LIMIT_WRITE_RPS=2
sudo systemctl reload memory-service

# 2. Enable enhanced logging
export MEMORY_AUDIT_LEVEL=debug
export MEMORY_AUDIT_OUTPUT=file
export MEMORY_AUDIT_FILE=/var/log/memory/audit-debug.log

# 3. Block suspicious IPs (if identified)
sudo ufw deny from 192.168.1.100 to any port 8080

# 4. Take database snapshot for forensics
turso db export prod-memory-db /tmp/incident-$(date +%Y%m%d%H%M%S).sql

# 5. Notify response team
send_alert "P1 HIGH: Strict rate limiting enabled, investigating"
```

#### For P2 - Medium Incidents

```bash
# 1. Increase monitoring frequency
# (adjust Prometheus scrape interval to 10s)

# 2. Alert on specific client
# block specific abusive client
echo "abusive-client-id" >> /etc/memory-service/blocked-clients.list

# 3. Collect additional logs
# enable verbose logging for affected service
export RUST_LOG=debug,memory_core=debug

# 4. Document incident
echo "$(date): P2 incident detected, investigating" >> /var/log/memory/incidents.log
```

### Isolation Techniques

#### Network Isolation

```bash
# Block all inbound traffic
sudo ufw default deny incoming

# Allow only from specific IPs (e.g., admin network)
sudo ufw allow from 10.0.0.0/8 to any port 8080

# Block specific IPs
sudo ufw deny from 192.168.1.100 to any
sudo ufw deny from 10.0.0.50 to any

# Block specific countries (using geoip)
sudo ufw deny from 192.0.2.0/24  # Example: Test network
```

#### Database Isolation

```bash
# Enable read-only mode
export MEMORY_READ_ONLY=true
sudo systemctl restart memory-service

# Disable write operations via rate limiting
export MCP_RATE_LIMIT_WRITE_RPS=0
sudo systemctl restart memory-service

# Create database snapshot
turso db export prod-memory-db /var/backups/emergency-$(date +%Y%m%d%H%M%S).sql

# Enable maintenance mode
# Return 503 Service Unavailable for all requests
export MEMORY_MAINTENANCE_MODE=true
```

#### Client Isolation

```bash
# Block specific client IDs
# (application-level blocking)
echo "abusive-client-1" >> /etc/memory-service/blocked-clients.list

# Block specific IPs
sudo ufw deny from 192.168.1.100 to any port 8080

# Throttle specific clients
# (custom rate limit per client)
# In RateLimiter implementation:
if client_id == "abusive-client" {
    return RateLimitResult {
        allowed: false,
        retry_after: Duration::from_secs(3600),  // 1 hour
    };
}
```

### Evidence Preservation

#### Log Collection

```bash
#!/bin/bash
# collect_evidence.sh

TIMESTAMP=$(date +%Y%m%d%H%M%S)
EVIDENCE_DIR="/tmp/incident-$TIMESTAMP"
mkdir -p "$EVIDENCE_DIR"

# 1. Application logs
sudo cp /var/log/memory/audit.log "$EVIDENCE_DIR/"
sudo journalctl -u memory-service --since "1 hour ago" > "$EVIDENCE_DIR/service.log"

# 2. System logs
sudo journalctl --since "1 hour ago" > "$EVIDENCE_DIR/system.log"

# 3. Network logs
sudo netstat -an > "$EVIDENCE_DIR/network.log"
sudo lsof -i :8080 > "$EVIDENCE_DIR/open-ports.log"

# 4. Database snapshot
turso db export prod-memory-db "$EVIDENCE_DIR/database.sql"

# 5. Rate limiter state
curl http://localhost:8080/metrics > "$EVIDENCE_DIR/metrics.log"

# 6. Create checksums
cd "$EVIDENCE_DIR"
sha256sum * > checksums.txt

# 7. Compress and encrypt
cd /tmp
tar -czf "incident-$TIMESTAMP.tar.gz" "incident-$TIMESTAMP/"
gpg --encrypt --recipient security@company.com "incident-$TIMESTAMP.tar.gz"

echo "Evidence collected: $EVIDENCE_DIR"
```

#### Database Forensics

```bash
# Query suspicious activity
turso db shell prod-memory-db << 'EOF'
-- Recent episode deletions
SELECT * FROM episodes
WHERE deleted_at IS NOT NULL
ORDER BY deleted_at DESC
LIMIT 100;

-- Recent bulk operations
SELECT actor, COUNT(*) as operations,
       MIN(timestamp) as first_op,
       MAX(timestamp) as last_op
FROM audit_logs
WHERE timestamp >= datetime('now', '-1 hour')
GROUP BY actor
HAVING operations > 100
ORDER BY operations DESC;

-- Failed authentication attempts
SELECT ip_address, COUNT(*) as failures
FROM audit_logs
WHERE event_type = 'auth_failure'
  AND timestamp >= datetime('now', '-1 hour')
GROUP BY ip_address
HAVING failures > 10
ORDER BY failures DESC;
EOF
```

## Eradication Procedures

### Remove Threat

#### Remove Malicious Clients

```bash
# 1. Identify malicious clients
grep "security_violation" /var/log/memory/audit.log | \
  jq -r '.actor' | sort | uniq -c | sort -rn | head -10

# 2. Block malicious clients
# Add to blocked list
for client in $(cat /tmp/malicious-clients.txt); do
    echo "$client" >> /etc/memory-service/blocked-clients.list
done

# 3. Block associated IPs
for ip in $(cat /tmp/malicious-ips.txt); do
    sudo ufw deny from $ip to any port 8080
done

# 4. Reload service
sudo systemctl reload memory-service
```

#### Patch Vulnerabilities

```bash
# 1. Update dependencies
cargo update

# 2. Run security audit
cargo audit

# 3. Build and test
cargo test --all
cargo build --release

# 4. Deploy patched version
sudo systemctl stop memory-service
sudo cp target/release/memory-service /opt/memory/bin/
sudo systemctl start memory-service

# 5. Verify patch
curl http://localhost:8080/health
```

#### Remove Backdoors

```bash
# 1. Scan for suspicious code
grep -r "eval\|exec\|system" src/ | grep -v "test\|benchmark"

# 2. Check for hardcoded credentials
grep -ri "password\|secret\|token" src/ | grep -v "// gitleaks:allow"

# 3. Review recent commits
git log --since="1 week ago" --pretty=format:"%h %s" | \
  while read commit; do
    git show $commit | grep -E "(password|secret|token)"
  done
```

### Fix Vulnerability

#### Configuration Review

```bash
#!/bin/bash
# review_config.sh

echo "=== Configuration Security Review ==="

# 1. Check environment variables
env | grep -E "(PASSWORD|TOKEN|SECRET)" | grep -v "MEMORY_AUDIT"

# 2. Check file permissions
ls -la /opt/memory/bin/
ls -la /var/log/memory/
ls -la /etc/memory-service/

# 3. Check rate limiting
echo "Rate limiting enabled: $MCP_RATE_LIMIT_ENABLED"
echo "Read RPS: $MCP_RATE_LIMIT_READ_RPS"
echo "Write RPS: $MCP_RATE_LIMIT_WRITE_RPS"

# 4. Check audit logging
echo "Audit enabled: $MEMORY_AUDIT_ENABLED"
echo "Audit level: $MEMORY_AUDIT_LEVEL"

# 5. Check network exposure
sudo ufw status | grep 8080
```

#### Apply Security Fixes

```bash
# 1. Enable audit logging (if not enabled)
export MEMORY_AUDIT_ENABLED=true
export MEMORY_AUDIT_LEVEL=info
export MEMORY_AUDIT_OUTPUT=file
export MEMORY_AUDIT_FILE=/var/log/memory/audit.log

# 2. Enable rate limiting (if not enabled)
export MCP_RATE_LIMIT_ENABLED=true
export MCP_RATE_LIMIT_READ_RPS=100
export MCP_RATE_LIMIT_WRITE_RPS=20

# 3. Restrict database access
# Ensure only libsql:// URLs are allowed
export TURSO_DATABASE_URL="libsql://prod-memory-db.turso.io"

# 4. Rotate secrets
# Generate new database token
turso db tokens create prod-memory-db --read-only

# 5. Restart service
sudo systemctl restart memory-service
```

## Recovery Steps

### Restore Service

#### Gradual Service Restoration

```bash
#!/bin/bash
# restore_service.sh

STAGE=1

echo "=== Stage $STAGE: Read-only access ==="
export MEMORY_READ_ONLY=true
export MCP_RATE_LIMIT_READ_RPS=10
export MCP_RATE_LIMIT_WRITE_RPS=0
sudo systemctl restart memory-service

# Wait and monitor
sleep 300  # 5 minutes

echo "=== Stage 2: Limited write access ==="
export MEMORY_READ_ONLY=false
export MCP_RATE_LIMIT_WRITE_RPS=5
sudo systemctl restart memory-service

# Wait and monitor
sleep 300

echo "=== Stage 3: Normal write access ==="
export MCP_RATE_LIMIT_WRITE_RPS=20
sudo systemctl restart memory-service

# Wait and monitor
sleep 300

echo "=== Stage 4: Normal operation ==="
unset MEMORY_READ_ONLY
export MCP_RATE_LIMIT_READ_RPS=100
export MCP_RATE_LIMIT_WRITE_RPS=20
sudo systemctl restart memory-service

echo "Service restored to normal operation"
```

#### Database Recovery

```bash
# 1. Verify database integrity
turso db shell prod-memory-db --execute "PRAGMA integrity_check;"

# 2. If corrupted, restore from backup
turso db restore prod-memory-db /var/backups/pre-incident.sql

# 3. Verify data
turso db shell prod-memory-db --execute "SELECT COUNT(*) FROM episodes;"

# 4. Replay audit logs (if needed)
# Reconstruct changes since backup
# (custom script to apply changes from audit logs)
```

### Verify Recovery

#### Health Checks

```bash
#!/bin/bash
# verify_recovery.sh

echo "=== Recovery Verification ==="

# 1. Service health
curl -f http://localhost:8080/health || exit 1

# 2. Database connectivity
turso db shell prod-memory-db --execute "SELECT 1;" || exit 1

# 3. Rate limiting
curl -I http://localhost:8080/api/episodes | grep -i "rate-limit" || exit 1

# 4. Audit logging
tail -5 /var/log/memory/audit.log | grep "audit" || exit 1

# 5. No critical errors
grep "CRITICAL" /var/log/memory/audit.log | tail -10 && exit 1

echo "Recovery verified successfully"
```

#### Monitor for Recurrence

```bash
# Monitor for 24 hours after recovery
while true; do
    # Check for critical events
    if grep "CRITICAL" /var/log/memory/audit.log | tail -1 | grep -q "$(date +%Y-%m-%d)"; then
        send_alert "Critical event detected post-recovery"
    fi

    # Check for rate limit violations
    violations=$(curl -s http://localhost:8080/metrics | grep rate_limit_denied_total | jq '.value')
    if [ "$violations" -gt 100 ]; then
        send_alert "High rate limit violations post-recovery: $violations"
    fi

    sleep 300  # Check every 5 minutes
done &
```
