Release Notes Tanium Quarantine (Version 3.4)
Tanium Quarantine 3.4.17
Release Date: November 1, 2022
Resolved Issues
- Fixes an issue where IR Quarantine on Linux sets the CIDR to 0 and IP to 0.0.0.0 instead of setting the CIDR to 32 when a custom rule has a blank CIDR.
Known Issues
- When using quarantine rules to block the ICMP protocol, the MTU negotiation packages can become blocked when the size of the MTU package on the endpoint is larger than the routers allowed MTU size. Normally the router will see a packet that is too large and send an ICMP packet to the endpoint to identify that the packet is too large and advises lowering the permissible MTU size. If the negotiation packet is not able to reach the destination due to quarantine, the endpoint can become unresponsive. The endpoint is still is quarantined but loses communication with the Tanium server. Disable ICMP at your own risk.
- Quarantine Notifications do not function on MacOS at this time.
