From a0e7fd71de3fd53868ac7f0a6f37a4db7d77601a Mon Sep 17 00:00:00 2001 From: Renz Date: Tue, 25 Nov 2025 12:03:21 +0000 Subject: [PATCH] security: Implement HIGH priority security improvements HIGH Priority Security Features: - Path sanitization with filepath.Clean() for all user paths - Path traversal attack prevention in backup/restore operations - Secure config file permissions (0600 instead of 0644) - SHA-256 checksum generation for all backup archives - Checksum verification during restore operations - Comprehensive audit logging for compliance New Security Module (internal/security/): - paths.go: ValidateBackupPath() and ValidateArchivePath() - checksum.go: ChecksumFile(), VerifyChecksum(), LoadAndVerifyChecksum() - audit.go: AuditLogger with structured event tracking Integration Points: - Backup engine: Path validation, checksum generation - Restore engine: Path validation, checksum verification - All backup/restore operations: Audit logging - Configuration saves: Audit logging Security Enhancements: - .dbbackup.conf now created with 0600 permissions (owner-only) - All archive files get .sha256 checksum files - Restore warns if checksum verification fails but continues - Audit events logged for all administrative operations - User tracking via $USER/$USERNAME environment variables Compliance Features: - Audit trail for backups, restores, config changes - Structured logging with timestamps, users, actions, results - Event details include paths, sizes, durations, errors Testing: - All code compiles successfully - Cross-platform build verified - Ready
