Subject: [PATCH] fix: Remove unnecessary async keywords from synchronous
 functions

- Fixed 62 SonarCloud code smell issues where functions were marked async but didn't use any async features
- Removed async keyword from functions that perform only synchronous operations
- Updated corresponding await calls to regular function calls
- Improves code clarity and prevents confusion about function behavior

This addresses SonarCloud's 'Use asynchronous features in this function or remove the async keyword' warnings

+# OpenWatch Security Architecture
+
+## Overview
+
+OpenWatch implements a comprehensive FIPS 140-2 compliant security architecture for secure OpenSCAP scanning operations. This document outlines the security controls, cryptographic implementations, and compliance measures.
+
+## FIPS 140-2 Compliance
+
+### Cryptographic Modules
+- **AES-256-GCM**: Data encryption at rest and in transit
+- **RSA-2048**: Digital signatures for JWT tokens
+- **SHA-256**: Hash functions and key derivation
+- **Argon2id**: Password hashing (FIPS approved)
+- **PBKDF2**: Key derivation with 100,000 iterations
+
+### Validation Status
+- OpenSSL FIPS module validation required for production
+- Cryptographic operations use only FIPS-approved algorithms
+- Runtime FIPS mode validation on application startup
+
+## Security Architecture
+
+### Transport Security
+```
+┌─────────────────────────────────────────────────────────────┐
+│                        TLS 1.3 Layer                       │
+│  ┌─────────────────────────────────────────────────────────┤

+│  │  │  │            Infrastructure Security              │
+└──┴──┴──┴─────────────────────────────────────────────────────┘
+```
+
+### Authentication Flow
+1. **User Authentication**: RSA-2048 signed JWT tokens
+2. **Service Authentication**: Mutual TLS between services
+3. **SSH Authentication**: Encrypted private keys for remote scans
+4. **Database Authentication**: SCRAM-SHA-256 with TLS
+
+### Authorization Model
+- **Role-Based Access Control (RBAC)**
+  - `admin`: Full system access
+  - `user`: Limited scan operations
+- **Resource-Level Permissions**: Host and scan access controls
+- **API Endpoint Protection**: JWT token validation required
+
+## Data Protection
+
+### Encryption at Rest
+- **Database**: PostgreSQL with TDE (Transparent Data Encryption)
+- **Credentials**: AES-256-GCM encryption for SSH keys and passwords
+- **Files**: SCAP content and results encrypted on disk
+- **Logs**: Audit logs with integrity protection
+
+### Encryption in Transit
+- **HTTPS/TLS 1.3**: All client communications
+- **Database TLS**: Encrypted PostgreSQL connections
+- **Redis TLS**: Secure Celery message passing
+- **SSH**: OpenSCAP remote scanning operations
+
+### Key Management
+- **Master Key**: Environment-based encryption key
+- **JWT Keys**: RSA-2048 key pair for token signing
+- **TLS Certificates**: X.509 certificates for service communication
+- **SSH Keys**: Per-host encrypted private keys
+
+## Network Security
+
+### Network Segmentation
+```

+```
+
+### Security Headers
+- **HSTS**: HTTP Strict Transport Security
+- **CSP**: Content Security Policy
+- **X-Frame-Options**: Clickjacking protection
+- **X-Content-Type-Options**: MIME sniffing protection
+
+## Audit and Compliance
+
+### Security Logging
+- **Authentication Events**: Login attempts and failures
+- **Authorization Events**: Access control decisions
+- **Scan Operations**: All OpenSCAP operations logged
+- **System Events**: Configuration changes and errors
+
+### Audit Trail
+- **Tamper Evident**: Cryptographic integrity protection
+- **Non-Repudiation**: Digital signatures on critical events
+- **Retention**: Configurable log retention periods
+- **Export**: SIEM integration capabilities
+
+### Compliance Reporting
+- **FIPS Validation**: Real-time compliance status
+- **Security Metrics**: Authentication and authorization metrics
+- **Vulnerability Scanning**: Regular security assessments
+- **Penetration Testing**: Periodic security validation
+
+## Secure Development
+
+### Security Testing
+- **Static Analysis**: Bandit security linting
+- **Dependency Scanning**: Safety vulnerability checks
+- **Secret Detection**: Pre-commit hook scanning
+- **Dynamic Analysis**: Runtime security testing
+
+### Code Security
+- **Input Validation**: All user inputs sanitized
+- **SQL Injection**: Parameterized queries only
+- **XSS Protection**: Output encoding and CSP
+- **CSRF Protection**: Token-based protection
+
+## Operational Security
+
+### Container Security
+- **Base Images**: FIPS-compliant Red Hat UBI
+- **Vulnerability Scanning**: Regular image updates
+- **Runtime Security**: Non-root container execution
+- **Resource Limits**: CPU and memory constraints
+
+### Infrastructure Security
+- **Secrets Management**: Environment-based configuration
+- **Access Control**: Principle of least privilege
+- **Network Policies**: Kubernetes network segmentation
+- **Monitoring**: Security event monitoring
+
+## Incident Response
+
+### Security Monitoring
+- **Failed Authentication**: Account lockout after 5 attempts
+- **Unusual Activity**: Anomaly detection and alerting
+- **System Health**: Continuous security posture monitoring
+- **Threat Detection**: Real-time security event analysis
+
+### Response Procedures
+1. **Detection**: Automated security event detection
+2. **Analysis**: Security team investigation
+3. **Containment**: Threat isolation and mitigation
+4. **Eradication**: Root cause remediation
+5. **Recovery**: Service restoration
+6. **Lessons Learned**: Post-incident review
+
+## Configuration Management
+
+### Security Baselines
+- **CIS Benchmarks**: Container and OS hardening
+- **NIST Guidelines**: Security control implementation
+- **DISA STIGs**: Military security requirements
+- **Custom Policies**: Organization-specific controls
+
+### Secure Defaults
+- **Encryption Enabled**: All data encrypted by default
+- **Strong Authentication**: Multi-factor authentication required
+- **Least Privilege**: Minimal permission grants
+- **Audit Logging**: Comprehensive security logging
+
+## Disaster Recovery
+
+### Backup Security
+- **Encrypted Backups**: AES-256 encryption for all backups
+- **Key Escrow**: Secure key recovery procedures
+- **Offsite Storage**: Geographically distributed backups
+- **Recovery Testing**: Regular disaster recovery drills
+
+### Business Continuity
+- **High Availability**: Multi-instance deployments
+- **Failover Procedures**: Automated service failover
+- **Data Replication**: Real-time data synchronization
+- **Recovery Objectives**: RTO < 4 hours, RPO < 1 hour
