|
||||
## RISK ASSESSMENT
|
||||
|
||||
### Current Risks (Pre-Fixes)
|
||||
🔴 **CRITICAL**: Tool doesn't work (bugs prevent execution)
|
||||
🔴 **SECURITY**: Zero security (no auth, rate limiting, or validation)
|
||||
🔴 **RELIABILITY**: Session leaks cause random crashes
|
||||
|
||||
### Residual Risks (Post-Phase 1)
|
||||
🟡 **HIGH**: Works but unsafe (no auth/security)
|
||||
🟡 **MEDIUM**: Could fail under load (SQLite bottleneck)
|
||||
|
||||
### Acceptable Risks (Post-Phase 2)
|
||||
🟢 **LOW**: Production-ready with known limitations
|
||||
🟢 **LOW**: Suitable for internal/controlled use
|
||||

|
||||
## BUSINESS IMPACT
|
||||
|
||||
### Current State
|
||||
- ❌ Tool cannot be deployed
|
||||
- ❌ Cannot be used in production
|
||||
- ❌ Security risk if exposed
|
||||
- ⚠️ Internal development only
|
||||
|
||||
### After Phase 1 (2.5 hrs)
|
||||
- ✅ Tool works end-to-end
|
||||
- ⚠️ Still unsafe for production
|
||||
- ⚠️ Still missing features
|
||||
- ✅ Can be used internally for testing
|
||||
|
||||
### After Phase 2 (10.5 hrs total)
|
||||
- ✅ Tool is production-ready
|
||||
- ✅ Secure for limited deployment
|
||||
- ✅ Suitable for small networks
|
||||
- ✅ Can be deployed with confidence
|
||||
|
||||
### After Phase 3 (17.5 hrs total)
|
||||
- ✅ Enterprise-ready
|
||||
- ✅ Scalable deployment
|
||||
- ✅ Comprehensive monitoring
|
||||
- ✅ Full test coverage

|
||||
## COST-BENEFIT ANALYSIS
|
||||
|
||||
### Investment Required
|
||||
- **Development**: 20 hours (~2 weeks for 1 developer)
|
||||
- **Testing**: 4-6 hours
|
||||
- **Deployment**: 2-4 hours
|
||||
- **Total**: ~26-30 hours (~1 month for 1 developer)
|
||||
|
||||
### Expected Benefit
|
||||
- Network discovery automation
|
||||
- Real-time topology visualization
|
||||
- Service detection and mapping
|
||||
- Reduced manual network auditing
|
||||
- Better infrastructure visibility
|
||||
|
||||
### ROI
|
||||
- **Break-even**: ~50 hours of manual network mapping saved
|
||||
- **Annual savings**: If tool saves 200 hours/year of manual work
|
||||
- **Value**: ~$10,000/year (assuming $50/hour labor cost)
