Release 8.8.4 Preview 1 - Security and Linux - Darius Panahy - 2023-09-18

Release 8.8.4 of the IET DevOps suite (including GuardIEn and Studio Developer) will be available on 21st September. This update contains some exciting new features and enhancements that will be previewed over the next few days.

This first preview focusses on security enhancements and support for Linux.

SSL/TLS support
Many of our customers are disallowing the use of plain unencrypted FTP. The GuardIEn client and Remote Processing Deamon (RPD) now support SSL/TLS encryption. This enables you to encrypt the data exchanged between the client and server using FTPS which can often be achieved through a setting on your existing FTP server rather than having to migrate to an alternative SFTP product.

Security Token
GuardIEn can now use a security token for user authentication. An example is when multi-factor authentication is enabled that requires a time-limited code to be included in the password and subsequent authentication using a generated token rather than the time-limited password.


A new server exit can be customised to generate a security token that is then returned to the client and can be inserted into the Gen Common Format Buffer sent on subsequent flows and used for authentication instead of the password. An example is when multi-factor authentication is enabled that requires a time-limited code to be included in the password. In this scenario, the initial logon will invoke the server exit which will generate a token (for example a JSON Web Token) which is returned to the client and then sent on subsequent server calls. The Gen runtime validation would then be customised to verify the user with the token rather than the password.

Support for Linux
The IET DevOps suite now supports Linux as a server platform to coincide with the recent support for Linux as a CSE platform.


Increased number of jobcard lines
The number of jobcard header lines supported by GuardIEn has been increased from 4 to 10, primarily to support long passwords in the jobcard.
