Issue/Introduction

The network security group would like to know what is the Communication Protocol for Mainframe to Agent communication that runs on top of TCP/IP (HTTP/HTTPS/..)?

 

Environment

Release : 11.4 &12.0

Component : CA ESP WORKLOAD AUTOMATION

Resolution

The communication between ESP and its agents uses TCP/IP and on top of that our proprietary protocol called AFM.

The AFM messages will be encrypted before being sent, and decrypted after being received. Here are the supported types of encryption:
DES -- Maximum 16 hexadecimal characters
BLOWFISH -- Maximum 64 hexadecimal characters
AES -- The limit determines the AES encryption method used as follows:
   AES 128 -- Exactly 32 hexadecimal characters
  AES 256 -- Exactly 64 hexadecimal characters

You can add AT-TLS layer on top of the TCP-IP for stronger security. The configurations on mainframe and distributed servers are outside of ESP and agent.
