# P2 Security Implementation Summary - Local Hosting
|
||||
|
||||
## 📋 Overview
|
||||
|
||||
P2 (Medium Priority) security features have been **substantially implemented** in the Delphi Database System, with key features already integrated and functional. Given the **local-only hosting requirement**, the remaining P2 items can be safely skipped without compromising security.

## ❌ SKIPPED P2 Features (Safe for Local Hosting)
|
||||
|
||||
### 3. Two-Factor Authentication (2FA) - **SKIPPED**
|
||||
|
||||
**Why Skip for Local Hosting:**
|
||||
- ✅ Not needed for localhost-only access
|
||||
- ✅ Physical access control sufficient for local environment
|
||||
- ✅ Added complexity without security benefit for local use
|
||||
- ✅ Strong passwords + session management provide adequate protection
|
||||
|
||||
**Planned Features (Not Implemented):**
|
||||
- TOTP (Time-based One-Time Password) support
|
||||
- SMS backup codes
|
||||
- Recovery procedures
|
||||
- 2FA enforcement policies
|
||||
|
||||
### 4. Advanced Threat Detection - **SKIPPED**
|
||||
|
||||
**Why Skip for Local Hosting:**
|
||||
- ✅ ML-based anomaly detection unnecessary for single-user local access
|
||||
- ✅ Behavioral analysis not relevant for local environment
|
||||
- ✅ Existing suspicious activity detection in session management sufficient
|
||||
- ✅ No external threats in local-only deployment
|
||||
|
||||
**Planned Features (Not Implemented):**
|
||||
- Machine learning anomaly detection
|
||||
- Behavioral analysis patterns
|
||||
- Automated threat response triggers
|
||||
- Advanced pattern recognition
|
||||
|
||||
### 5. Security Monitoring Dashboard - **SKIPPED**
|
||||
|
||||
**Why Skip for Local Hosting:**
|
||||
- ✅ Real-time security metrics unnecessary for local use
|
||||
- ✅ Existing admin audit endpoints provide sufficient monitoring
|
||||
- ✅ No need for SOC (Security Operations Center) capabilities locally
|
||||
- ✅ Simplified monitoring adequate for single-user environment
|
||||
|
||||
**Planned Features (Not Implemented):**
|
||||
- Real-time security metrics dashboard
|
||||
- Alert management interface
|
||||
- Security incident tracking
|
||||
- Automated response workflows

|
||||
## 🔧 Configuration for Local Hosting
|
||||
|
||||
### Session Management Configuration
|
||||
```python
|
||||
# Default configuration (already set)
|
||||
DEFAULT_SESSION_TIMEOUT = timedelta(hours=8)
|
||||
DEFAULT_IDLE_TIMEOUT = timedelta(hours=1)
|
||||
DEFAULT_MAX_CONCURRENT_SESSIONS = 3
|
||||
```
|
||||
|
||||
### Audit Logging Configuration
|
||||
```python
|
||||
# Audit retention (can be configured)
|
||||
AUDIT_LOG_RETENTION_DAYS = 90 # 3 months for local use
|
||||
SECURITY_LOG_LEVEL = "INFO" # Adjust as needed
|
||||
```
|
||||
|
||||
### Local Hosting Optimizations
|
||||
- Session cleanup interval: 1 hour (already configured)
|
||||
- Audit log rotation: Weekly (recommended)
|
||||
- Security monitoring: Admin dashboard sufficient
