Where is the secure protocol defined for EEM, and how can we control the ciphers that are used for these secure connections?
The protocol and ciphers are controlled in the igateway.conf file located here:
%IGW_LOC% or $IGW_LOC
To set the TLS protocol, search in the file for secureProtocol and modify that line as follows:
Next search the file for cipherlist and modify that line as follows:
You might set the values as -ALL:HIGH:MEDIUM:!RC4 so that it would look like
The list of supported ciphers for EEM are:
Changes to the igateway.conf file require a restart of igateway.
Settings are only valid for EEM version 12.5.1 CR04 and later
Please see https://www.openssl.org/docs/man1.0.2/apps/ciphers.html (OpenSSL version 1.0.2) for formatting information on setting ciphers and additional information on ciphers
