CIS benchmark compliance verification remains a manual, time-consuming process for Linux infrastructure teams. System administrators must execute hundreds of individual checks across server fleets, document findings, and track remediation efforts. This workflow becomes impractical at scale.

AuditRite automates the complete CIS compliance lifecycle for Debian-based systems. The platform accepts server credentials through a web interface, executes benchmark tests in isolated containers, and generates detailed compliance reports with specific remediation guidance.

The system targets Debian 12+ and Ubuntu 22.04+ LTS distributions. It implements CIS Level 1 and Level 2 controls covering system configuration, access controls, network parameters, and logging requirements.

The architecture separates concerns into three layers: a Next.js frontend for credential management and results display, a Python orchestration backend for job scheduling, and isolated Docker containers for audit execution.

The web interface provides two input methods: manual entry for individual servers and CSV upload for fleet operations. Users specify hostname, SSH credentials, username, and operating system type. The interface validates inputs and maintains a session-scoped inventory table.

The backend orchestration layer uses FastAPI to expose REST endpoints for job submission and status polling. When a compliance scan request arrives, the system provisions an ephemeral Docker container with Ansible installed, injects encrypted credentials, and executes CIS benchmark playbooks against target hosts.

Audit containers run with minimal privileges and network isolation. They connect only to specified target systems via SSH. Upon completion, results are extracted, the container is destroyed, and credentials are purged from memory.

The platform implements CIS benchmark controls through Ansible playbooks that map to specific security requirements. Each control consists of an automated check and remediation logic.

System configuration checks verify filesystem mount options, kernel parameter settings, and bootloader configurations. Authentication controls validate password policies, account lockout mechanisms, and SSH hardening. Network checks assess firewall rules, protocol configurations, and service exposure.

The execution engine runs checks in dependency order. Failed controls trigger conditional logic to determine severity and collect diagnostic data. The system captures command outputs, configuration file contents, and system state for each finding.

Remediation guidance includes specific commands to resolve each issue. For controls requiring manual review, the system provides context about the security implication and decision criteria. MITRE ATT&CK mappings link controls to relevant threat techniques.

Security credentials follow a strict lifecycle with minimal exposure time. The frontend encrypts passwords before transmission using the backend's public key. Encrypted credentials remain in memory only during active scan operations.

SSH connections use parameterized commands to prevent injection attacks. The system validates hostnames against IP address patterns and rejects potentially malicious input. Connection timeouts prevent hung sessions from holding credentials indefinitely.

Container destruction includes explicit memory clearing operations. Docker volumes are not mounted persistently. Temporary files containing credentials are securely deleted using overwrite operations before container termination.

The system does not store credentials in any database or logging system. Users must provide credentials for each scan session. This design eliminates credential theft risks from compromised storage systems.

Audit results undergo multi-stage processing to generate actionable compliance reports. Raw Ansible output is parsed into structured JSON containing control IDs, pass/fail status, diagnostic data, and remediation steps.

The aggregation service categorizes findings by severity level and compliance impact. Critical failures affecting authentication or access control are flagged for immediate attention. Informational findings requiring manual review are separated from automated checks.

The dashboard presents compliance metrics through multiple visualizations. A pie chart shows overall compliant versus non-compliant control distribution. A summary panel displays total device counts, online/offline status, and last scan timestamps.

Detailed results list each control with its status, impact description, and remediation command. Users can filter by severity, control category, or compliance status. Export functions generate CSV and JSON files suitable for audit documentation and tracking systems.

The audit workflow follows a four-phase process: inventory collection, job scheduling, parallel execution, and result compilation.

During inventory collection, users add hosts manually or upload a CSV file containing hostname, username, password, and OS columns. The system validates each entry for completeness and flags duplicates. The interface displays the current inventory in a sortable table with edit and delete capabilities.

Job scheduling batches hosts by operating system type to optimize container image reuse. The scheduler enforces concurrency limits to prevent resource exhaustion. Each job receives a unique identifier for status tracking.

Parallel execution spawns independent containers for each target host. This isolation prevents failure propagation and enables concurrent scanning. The system monitors container health and automatically retries failed connections due to transient network issues.

Result compilation aggregates findings across all scanned hosts. The system calculates fleet-wide compliance percentages and identifies common configuration gaps. A consolidated report shows which controls failed most frequently, helping prioritize remediation efforts.

The web interface prioritizes clarity and efficient data entry. The main screen uses a tabbed layout separating manual input from bulk CSV upload. Form validation provides immediate feedback on missing or invalid fields.

The selected hosts table shows all queued systems with inline editing capabilities. Users can modify credentials, change OS selection, or remove hosts before initiating scans. Badge indicators display the configured operating system for quick verification.

During scan execution, a progress indicator shows the number of completed checks and remaining hosts. Real-time updates notify users when individual hosts finish or encounter errors. Connection failures display specific error messages to aid troubleshooting.

The results dashboard uses a dark theme with color-coded status indicators. Green represents compliant controls, red shows failures, and yellow indicates items requiring manual review. Each finding expands to reveal full technical details and remediation instructions.

The backend uses FastAPI for asynchronous request handling and SSE (Server-Sent Events) for real-time progress updates. Docker SDK for Python manages container lifecycle programmatically.

Ansible playbooks are version-controlled separately from application code. Each CIS benchmark version maps to a specific playbook release. The system supports multiple benchmark versions simultaneously for organizations in transition.

Container images are built with minimal dependencies. Base images use official Debian/Ubuntu variants with Ansible and required modules pre-installed. Layer caching reduces cold-start times for scan operations.

Error handling covers network timeouts, authentication failures, and malformed playbook outputs. Each error type returns structured JSON with diagnostic information. The system logs errors without exposing sensitive credential data.

Scan duration depends on target system responsiveness and control count. A typical Level 1 audit covering 150 controls completes in 8-12 minutes per host. Level 2 audits with additional checks require 15-20 minutes.

The system supports concurrent scanning of up to 50 hosts depending on available resources. Each container consumes approximately 100MB RAM and minimal CPU during SSH operations. Network bandwidth requirements are low as most checks involve command execution rather than data transfer.

Container startup adds 2-3 seconds per scan. Image pull times are amortized across multiple scans when images are cached locally. The scheduler prioritizes container reuse when scanning multiple hosts with identical OS versions.

Report generation completes within 5 seconds for fleets under 100 hosts. CSV export handles thousands of findings without pagination. The dashboard remains responsive with real-time filtering across large result sets.

Deployment in production environments demonstrates significant time reduction. Manual CIS audits previously requiring 4-6 hours per server now complete in 10-15 minutes through automation. This enables weekly compliance checks instead of quarterly assessments.

Automated remediation guidance reduces resolution time. System administrators no longer need to research individual controls or consult lengthy benchmark documentation. Copy-paste commands provide immediate fixes for common configuration gaps.

The ephemeral container approach eliminates credential management overhead. Teams avoid maintaining dedicated audit infrastructure or credential vaults. Each scan operates independently without persistent security attack surface.

Organizations report improved audit preparedness. Regular automated scans identify drift before external audits. The detailed reports satisfy auditor documentation requirements without additional evidence collection.
