MiNiFi Java agent updates
MiNiFi Java agents has periodic software updates made available independent of the Edge Flow Manager (EFM) releases.
This section lists major features and updates for the independent CEM MiNiFi Java agent release.
April 18, 2023
CEM MiNiFi Java Agent - 1.23.04release includes:
- FIPS compatibility for MiNiFi Java
MiNiFi Java can be run in FIPS enabled environments and it can use Bouncy Castle FIPS keystores (BCFKS).
- Support access through Load Balancer/Proxy
When agents are behind Load Balancer/Proxy, EFM relies on the X-FORWARDED-HOST header to create absolute download URLs for the agents (flow, asset, and file transfer). Not all Load Balancers or Proxies support this header or they can be configured to remove it, so to bypass the issue the agent can rely on the relative path sent by EFM (from version 220.127.116.11) and combine it with the host configured for the agent to create the proper absolute URL. Three new properties have been introduced while keeping backward compatibility so the old ones can still be used. The old properties will be removed in a future release.The new properties are:
- Base path of the C2 server's REST API
For example: http://localhost/efm/api
- Relative URL of the C2 server's heartbeat endpoint
For example: /c2-protocol/heartbeat
- Relative URL of the C2 server's acknowledge endpoint
For example: /c2-protocol/acknowledge

Debug bundles can be requested from EFM Agent Manager for the given agent. For more details, see Debug agent in CEM.
