SSL/TLS Certificate Configuration for Infor SyteLine
Securing SyteLine with SSL/TLS certificates protects manufacturing data in transit between browsers, mobile clients, and the SyteLine application server. Misconfigured certificates cause login failures, IDO connection errors, and broken integrations that are difficult to diagnose. This guide covers the complete certificate lifecycle for SyteLine deployments.
Certificate Requirements for SyteLine Components
SyteLine uses multiple communication channels that each require certificate configuration. The Web UI served through IIS, the IDO Request Processor, REST API endpoints, and any integration services all need proper TLS bindings. A wildcard certificate or Subject Alternative Name (SAN) certificate simplifies management across these components.
- IIS HTTPS binding for the SyteLine Web UI site with TLS 1.2 minimum protocol
- IDO Request Processor endpoint encryption for client-to-server IDO calls
- SyteLine REST API endpoints requiring certificate-based mutual TLS for B2B integrations
- SAN certificate covering web server FQDN, application server name, and load balancer VIP
- Separate internal CA certificates for SyteLine-to-SQL Server encrypted connections
IIS Certificate Binding and Protocol Hardening
Windows Server and IIS require explicit configuration to disable legacy protocols and weak cipher suites. SyteLine's .NET framework version determines the minimum TLS version supported. After binding certificates, verify that SyteLine forms, Crystal Reports, and IDO calls all function correctly over HTTPS.
- Disable TLS 1.0 and 1.1 via Windows Registry or IIS Crypto tool on all SyteLine servers
- Configure cipher suite order prioritizing ECDHE and AES-GCM for forward secrecy
- HTTP Strict Transport Security (HSTS) header on SyteLine IIS sites with 1-year max-age
- Redirect HTTP port 80 to HTTPS port 443 in IIS URL Rewrite rules
- Certificate pinning considerations for SyteLine mobile client connections
Certificate Renewal and Monitoring
Certificate expiration is the most common cause of unplanned SyteLine outages related to security configuration. Automated renewal with monitoring and alerting prevents these avoidable incidents. Let's Encrypt, Azure Key Vault, or AWS Certificate Manager can automate the renewal lifecycle.
- Automated certificate renewal using ACME protocol with Let's Encrypt or enterprise CA
- Azure Key Vault or AWS Certificate Manager integration for centralized certificate management
- Certificate expiration monitoring with alerts at 60, 30, and 7 days before expiry
- PowerShell scripts to rebind renewed certificates to IIS sites and restart SyteLine services
- Annual certificate audit covering all SyteLine endpoints, integrations, and internal services
