4. SSL Security features
Sena now takes COM Port Redirection a step further with encryption features, offering a secure
Ethernet connection between the COM port and a Sena device server or terminal server.
When working with the Serial/IP COM Port Redirector and OpenSSL Toolkit, the new SSL/TLS
Security option offers a selection of five ciphers (including 3-DES and AES) and strengths up to
256 bits, sufficient to meet the tough security requirements encountered in the financial services
industry.
