investment in serial technology, while taking advantage of the highest data-protection 
levels possible. 
SSH and SSL can: 
  Verify the data received came from the proper source  
  Validate that the data transferred from the source over the network has not 
changed when it arrives at its destination (shared secret and hashing) 
  Encrypt data to protect it from prying eyes and nefarious individuals 
  Provide the ability to run popular M2M protocols over a secure SSH connection  
In addition to keeping data safe and accessible, the EDS has robust defenses to hostile 
Internet attacks such as denial of service (DoS), which can be used to take down the 
network. Moreover, the EDS cannot be used to bring down other devices on the network. 
The EDS can be used with Lantronix’s Secure Com Port Redirector (SCPR) to encrypt 
COM port-based communications between PCs and virtually any electronic device. 
SCPR is a Windows application that creates a secure communications path over a 
network between the computer and serial-based devices that are traditionally controlled 
via a COM port. With SCPR installed at each computer, computers that were formerly 
“hard-wired” by serial cabling for security purposes or to accommodate applications that 
only understood serial data can instead communicate over an Ethernet network or the 
Internet. 
The EDS also supports a variety of popular cipher technologies including: 
  Advanced Encryption Standard (AES) 
  Triple Data Encryption Standard (3DES) 
  RC4 
  Hashing algorithms such as Secure Hash Algorithm (SHA-1) and MD5 
Troubleshooting Capabilities 
The EDS offers a comprehensive diagnostic toolset that lets you troubleshoot problems 
quickly and easily. Available from the Web Manager, CLI, and XML interfaces, the 
diagnostic tools let you: 
  View critical hardware, memory, MIB-II, buffer pool, and IP socket information. 
  Perform ping and traceroute operations. 
  Conduct forward or backup DNS lookup operations. 
  View all processes currently running on the EDS, including CPU utilization and 
total stack space available.
