Why Choose Diplomat MFT Basic Edition for Secure File Transfers

Diplomat Managed File Transfer Basic Edition: Setup Guide & Best Practices—

Introduction

Diplomat Managed File Transfer (MFT) Basic Edition provides a streamlined way to automate, secure, and monitor file transfers for small-to-medium environments. This guide walks through installation, initial configuration, common workflows, security hardening, troubleshooting, and operational best practices to get the most from your Basic Edition deployment.

System requirements and planning

Recommended system specs

Operating systems: Windows Server 2016/2019/2022 or Linux (RHEL/CentOS 7–8, Ubuntu 18.04/20.04).
CPU: 4+ cores.
RAM: 8+ GB (16 GB recommended for higher concurrency).
Disk: SSD with 100+ GB available for transfers/logs; separate partitions for OS and data recommended.
Network: 1 Gbps NIC; static IP recommended.

Planning considerations

Estimate concurrent connections and transfer volume to size CPU, memory, and storage.
Decide whether the Basic Edition will act as an edge transfer server behind a reverse proxy or be exposed directly.
Plan backup/restore for configuration and transfer archives.
Choose authentication method (local accounts vs. LDAP/AD integration).

Installation

Pre-installation checklist

Confirm OS updates and required packages are installed.
Open required firewall ports (commonly TCP 21 for FTP, 22 for SFTP, and any application-specific ports—consult product docs for exact ports).
Ensure time synchronization (NTP) is enabled.
Create service account for the Diplomat application with least privilege.

Installation steps (high-level)

Obtain the Basic Edition installer or package from your vendor portal.
Run the installer as administrator/root.
During install, specify the installation directory and data directory (keep data on separate, durable storage).
Configure the application service to run under the service account created earlier.
Start the service and confirm it is running.

Initial configuration

License activation

Apply your Basic Edition license key in the admin console or via the provided license utility. Confirm license shows as active.

Administrative access

Create an initial admin user with a strong password. If available, enable multi-factor authentication (MFA) for the admin account.
Restrict admin console access to trusted IP ranges via built-in access controls or network firewall.

Network and protocol settings

Enable the transport protocols you require: SFTP, FTPS, AS2, HTTPS, etc. Disable unused protocols to reduce attack surface.
Configure passive port ranges for FTP/FTPS and open them in the firewall.
If using TLS: install a valid certificate from your CA; avoid self-signed certs in production.

Storage and retention

Configure storage locations for incoming/outgoing files and set retention policies to purge old files regularly.
Enable disk quotas per user or workflow if supported to avoid consuming all storage.

User accounts, roles, and access control

Accounts and authentication

Prefer centralized authentication (LDAP/Active Directory) when available to simplify user management.
For local accounts, enforce strong password policies and account lockout thresholds.

Roles and permissions

Follow the principle of least privilege. Create roles for operators, auditors, and administrators with narrowly scoped permissions.
Audit role assignments periodically.

Home directories and chroot

Use chroot/jail for SFTP or isolate FTP users to their home directories to prevent lateral file-system access.

Creating and scheduling transfers

Job/workflow creation

Create transfer jobs with clear names and descriptions. Include source, destination, triggers, and error-handling steps.
Use variables or tokens for reusable workflows (dates, client IDs).

Triggers and scheduling

Supported triggers: cron-like schedules, file arrival, API/webhook, or manual.
For time-sensitive transfers, ensure server clock sync and that schedules account for DST changes.

File processing and transformations

Use built-in steps for compression, encryption, or format conversion where available.
For encryption-at-rest and in-transit, prefer industry-standard algorithms (e.g., AES-256).

Security hardening

Network security

Place Diplomat MFT behind a firewall and limit management access to specific IPs or a VPN.
If exposing to the public internet, use a reverse proxy or WAF to protect the admin interface and web endpoints.

Encryption and certificates

Require TLS for all web and protocol endpoints; use strong ciphers and disable obsolete protocols (e.g., TLS 1.0/1.1).
Rotate certificates before expiration and maintain an inventory of certs.

Key management

Use secure key storage for any private keys. If the product supports HSM or cloud KMS integration, prefer those options.
Rotate encryption keys on a scheduled policy and after any suspected compromise.

Logging and monitoring

Enable detailed logging for transfers, authentication events, and administrative actions.
Forward logs to a centralized SIEM or log collector (e.g., syslog, Splunk, or ELK) for retention and alerting.
Monitor disk usage, queue backlogs, and failed transfer rates.

High-availability and backups

Backup strategy

Regularly back up configuration, job definitions, certificates, and any metadata required to restore service.
Test restores periodically on a dev instance.

Redundancy

Basic Edition may have limited HA features; consider using OS-level clustering, filesystem replication, or database replication where supported.
Use network load balancers and DNS health checks to route clients during maintenance windows.

Troubleshooting common issues

Service won’t start: check service account permissions, application logs, and binding ports for conflicts.
Authentication failures: verify LDAP/AD connectivity, clock skew, and password policies.
Transfer timeouts or hangs: inspect network path, firewall rules, and passive port configurations.
Disk space errors: review retention policies, clean archives, and check for runaway temp files.

Log locations and diagnostic tools vary by platform—consult product docs for exact paths and recommended diagnostic commands.

Best practices checklist

Use strong authentication (MFA + centralized identity).
Encrypt all in-transit and at-rest data with current algorithms.
Restrict protocol and admin access to necessary sources only.
Automate backups and test restores regularly.
Monitor logs and set alerts for failed transfers, repeated failures, or abnormal activity.
Use separate storage volumes for application data and OS.
Document workflows and runbooks for operators and incident response.

Example: Simple SFTP job (conceptual)

Create SFTP endpoint for partner with chrooted home directory.
Add public key authentication for partner’s account.
Create a job: trigger on file arrival in /incoming/{partner}, validate filename pattern, move processed files to /archive/{partner} and notify via email on completion/failure.
Schedule retention to purge archives older than 90 days.

Maintenance and lifecycle

Keep Diplomat and underlying OS packages up to date with security patches.
Review job definitions quarterly to remove obsolete workflows and stale accounts.
Maintain an inventory of endpoints, certificates, and keys.

Conclusion

Following the steps above will help you deploy Diplomat Managed File Transfer Basic Edition securely and reliably. Prioritize strong authentication, encryption, diligent logging, and tested backup/restore processes. For product-specific commands, port numbers, and advanced features, consult the vendor documentation included with your Basic Edition.
