Implementation Components
Backend Infrastructure
1. ThresholdManager (backend/utils/thresholdManager.js)
Purpose: Manage configurable notification thresholds
Key Features:
- Database table:
security_thresholds - 8 default thresholds (brute force, credential stuffing, privilege escalation, etc.)
- CRUD operations for threshold management
- Real-time threshold evaluation
- Statistical operators (>=, >, <=, <, ==, !=)
- CWE-778 logging for all operations
Default Thresholds:
[
{
pattern_type: 'brute_force_attack',
metric_name: 'failed_login_count',
operator: '>=',
threshold_value: 5,
time_window_minutes: 10,
severity: 'critical'
},
// ... 7 more default thresholds
]
API Methods:
evaluateThreshold(patternType, metricName, value, context)- Evaluate if metric exceeds thresholdgetThresholds(filters)- Get all thresholds with optional filterscreateThreshold(data, userId)- Create new thresholdupdateThreshold(thresholdId, updates, userId)- Update existing thresholddeleteThreshold(thresholdId, userId)- Delete thresholdgetStatistics()- Get threshold statistics
2. RiskSignatureManager (backend/utils/riskSignatureManager.js)
Purpose: Manage predefined risk signatures for threat detection
Key Features:
- Database table:
risk_signatures - 12 default signatures (malicious bots, SQL injection, XSS, etc.)
- Pattern matching engine (regex, exact, contains, custom)
- Threat level classification (low, medium, high, critical)
- Auto-block capabilities
- CWE-778 logging for all matches
Signature Types:
ip_address- IP-based threats (TOR, suspicious ranges)user_agent- Malicious bots and scannersattack_pattern- SQL injection, XSS, path traversal, command injectionbehavior- Brute force, credential stuffing, privilege escalation, data exfiltration
Default Signatures:
[
{
signature_id: 'SIG-UA-BOT-MALICIOUS',
name: 'Malicious Bot User-Agent',
signature_type: 'user_agent',
pattern: '(scrapy|python-requests|curl|wget|nikto|sqlmap|havij|acunetix|nessus|openvas)',
match_type: 'regex_case_insensitive',
threat_level: 'high',
confidence: 0.95,
auto_block: true
},
// ... 11 more default signatures
]
API Methods:
matchSignatures(input, signatureType, context)- Match input against signaturesgetSignatures(filters)- Get all signatures with optional filterscreateSignature(data, userId)- Create new signatureupdateSignature(signatureId, updates, userId)- Update existing signaturedeleteSignature(signatureId, userId)- Delete signaturegetStatistics()- Get signature statistics
3. ResponseProtocolManager (backend/utils/responseProtocolManager.js)
Purpose: Automate security incident response
Key Features:
- Database tables:
response_protocols,protocol_executions - 7 default protocols for common threats
- Event-driven execution (anomaly, threshold, signature)
- Multiple action types
- Cooldown periods to prevent flooding
- Execution history tracking
- CWE-778 logging for all executions
Action Types:
block_ip- Block IP address (with duration)lock_account- Lock user account (with duration)revoke_sessions- Revoke all active sessionsrequire_2fa- Enforce 2FA requirementrate_limit_ip- Apply rate limitingnotify_admin- Send admin notification (email, in-app, webhook)escalate_incident- Escalate to security teamlog_incident- Create incident log entryenable_enhanced_monitoring- Activate enhanced monitoring mode
Default Protocols:
[
{
protocol_id: 'PROTOCOL-BRUTE-FORCE-RESPONSE',
name: 'Brute Force Attack Response',
trigger_type: 'anomaly',
trigger_condition: { anomaly_type: 'brute_force_attack', severity: 'critical' },
actions: [
{ action: 'block_ip', duration_minutes: 60, reason: 'brute_force_attack' },
{ action: 'notify_admin', channel: 'email', priority: 'high' },
{ action: 'log_incident', category: 'security_breach' }
],
severity: 'critical',
auto_execute: true,
cooldown_minutes: 30
},
// ... 6 more default protocols
]
API Methods:

4. Enhanced SecurityIntelligence (backend/utils/securityIntelligence.js)
Enhancements:
- Integrated with ThresholdManager for dynamic threshold evaluation
- Uses configured thresholds instead of hardcoded values
- Evaluates thresholds before creating anomalies
- Enhanced CWE-778 logging for all threshold checks
Example Integration:
// Before (hardcoded)
const threshold = 10; // failed attempts
// After (configurable)
const thresholdConfig = await thresholdManager.getThresholds({ patternType: 'brute_force_attack' });
const threshold = thresholdConfig[0]?.threshold_value || 10;
// Evaluate threshold
const thresholdResult = await thresholdManager.evaluateThreshold(
'brute_force_attack',
'failed_login_count',
row.attempt_count,
{ ip_address: row.ip_address, timeWindow }
);
5. Enhanced AlertSystem (backend/utils/alertSystem.js)
Enhancements:
- Integrated with ResponseProtocolManager
- Automatically executes response protocols when alerts trigger
- Logs all protocol executions (CWE-778)
- Event-driven automation
Example Integration:
// After alert creation, execute response protocols
await this.executeResponseProtocols('anomaly', {
anomaly_type: anomaly.type,
severity: rule.severity
}, {
alertId,
ip_address: anomaly.affected_ip,
user_id: anomaly.affected_user_id,
confidence: anomaly.confidence
});

Log Format

'threshold_manager', // Source
'info', // Level
'security', // Category
'Threshold evaluated', // Message
{ // Metadata
thresholdId: 'THRESHOLD-...',

Security Considerations
Admin-Only Access
- All configuration endpoints require
security.managepermission - Only admin users can create/modify/delete thresholds, signatures, and protocols
Validation
- Input validation on all API endpoints
- Regex pattern validation for signatures
- Operator validation for thresholds
- Field type validation
Auto-Execution Safeguards
- Protocols have
auto_executeflag (default: false for critical actions) - Cooldown periods prevent execution flooding
- Execution history for audit trail
- Warning alerts in UI
Signature Testing
- Pattern testing before deployment
- Dry-run capability (future enhancement)
- Confidence scoring
