SmartSlim Server

Single-machine deployment compression service · based on Python 3.9+ and FastAPI, aligned with NIST CSF 2.0 / FedRAMP / FISMA, on-premises operation data stays within domain

Product Overview

Lightweight compression service for single-machine server scenarios

SmartSlim Server is a based on Python 3.9+ and FastAPI framework single-machine deployment compression service built with. It to HTTP API externally as provides compression capabilities, suitable for intranet environment as a shared service running. The version focuses on PDF, image (JPG/TIFF) and OFD three high-frequency documentation format, accompanied by complete production security capability, aligns with NIST CSF 2.0, FedRAMP and FISMA compliant deployment.

Tech Stack: Python 3.9+ · FastAPI · thread pool (maximum 12 concurrent) · single file limit 1GB
Supports format: PDF · image (jpg / jpeg / tif) · OFD
Format Note: Server version current configuration enables PDF, image (JPG/JPEG/TIF) and OFD three categories of formats. For Word/Excel/PPT/video/audio etc. Full Format Support please use SmartSlim Enterprise.

7 Production Security Capabilities

Designed for ministry-level security requirements, covering the entire compression workflow

Command Parameter Validation

Whitelist verification of command parameters for external tool calls, detection and blocking of path traversal attacks, validation of file extension legitimacy.

File Integrity Verification

Hash values computed for input and output files, ensuring files are not tampered with before or after compression. Higher security levels append stronger hash algorithms.

Malware Scanning

Integrated antivirus engine, supports before compression/compressed bidirectional scanning, malicious files are automatically isolated (quarantine), scan results cacheable to improve performance.

Audit Log (Tamper Protection)

Structured records of time, user, file, status and other metadata per operation, with a tamper-proof mechanism linking log entries; any tampering causes verification to fail.

Rate Limiting

Time window based rate limiting, by IP or user dimension, preventing brute force calls and denial of service attacks.

Secure Temporary File Management

Temporary files isolated in independent directories, securely erased after task completion. High security levels perform multiple overwrite passes.

File Size Limit

Upload file size verification, default single file limit 1GB, requests exceeding the limit are directly rejected.

Security Capabilities: Covers command parameter validation, file integrity verification, audit logging, malware scanning, rate limiting and other modules, comprehensively safeguarding service operation security.

5 Security Levels

From disabled to maximum security, choose as needed

MAXIMUM(maximum security)

Enabled all security feature · multi-algorithm file integrity verification · before compression after bidirectional scanning · multiple overwrite secure erasure · disabled scan cache · any warning abort immediately

HIGH(high security)

Enabled all security feature · file integrity verification · before compression after bidirectional scanning · multiple overwrite erasure · tamper-proof audit · scan fail abort immediately

MEDIUM(in etc. security · default)

Command verification + input hash + before compression scan + audit log + rate limitation + temporary file management + file size verification

LOW (low security)

Command verification + audit log + file size verification (not scan malicious code, not verification complete, not rate limiting)

DISABLED(disabled)

Close all security feature, only for controlled test environment use

Default Level: system default adopts MEDIUM security level. Production environments recommended to use HIGH, classified scenarios use MAXIMUM.

Deployment Methods

Adapted for various runtime environments, including federal compliance standards

Docker Container Deployment

Provides Dockerfile, can be built as container image running, for easy in container orchestration platform unified management in.

systemd Service

Provides systemd service unit files, supports auto-start on boot and auto-restart.

supervisor Process Management

Provides supervisor configuration, supports multi-process and log rotation.

Compliance Adaptation

Provides dedicated install scripts for NIST SP 800-53 and FedRAMP aligned environments, performing dependency and path adaptation.

Configuration Parameters: thread pool maximum concurrent 12; single file limit 1GB; server-side port 5001 (HTTP)/ 8443 (HTTPS).

RESTful API Integration

Open standard interfaces for easy integration with office systems / OA / CRM

SmartSlim Server provides standard RESTful API supporting HTTP/HTTPS protocol calls, enabling seamless integration with existing office systems, OA systems, and CRM systems for automated document compression without manual intervention.

OA System Integration

Automatically compress official document attachments and circulating documents in office automation workflows, reducing storage usage and improving system circulation efficiency. Adapts to approval, notification, archiving and other office scenarios.

CRM System Integration

Compress and optimize contract scans, product images, reports and other files in customer data, reducing customer data storage costs and improving system response speed.

Archive Management System Integration

Integrate with archive management systems to batch compress archived files, reducing long-term storage costs and meeting digital archive management requirements.

Integration Method: Upload files via HTTP POST with specified compression parameters, server processes and returns compressed results. Supports both synchronous and asynchronous calling modes to adapt to different business throughput requirements.
