Known Issues
Known Issues Discovered in Previous Releases
The following is a list of known issues that were discovered in previous releases
of the Sourcefire 3D System:
•
You must use the Defense Center’s web interface to unregister a managed
device. If you unregister a device using either the device’s web interface or
its command line interface (CLI), it is not removed from the Defense Center.
(112659)
•
The system will generate a health alert if the Defense Center is unable to
connect to the Sourcefire cloud. To troubleshoot, ensure the connection
from the Defense Center to the Sourcefire cloud (
54.243.248.19
and
54.243.248.162
) on port 32137 is working properly. (112708)
•
If multiple files are attached to a single email, the system may incorrectly
identify files after the first. (114523)
•
If you attempt to create multiple static NAT rules with the same original
values, the system may experience issues with traffic mapping. (116148)
•
In some cases, the Defense Center may show a cluster in a degraded state
when it has already recovered, generating extraneous system alerts.
(118122)
•
When Lights-Out Management is enabled, the system also enables a web
server in the background. The web server does not drain system resources
and has no known exploits. (119456)
•
Sourcefire documentation currently does not reflect that, on a Series 3
device, TCP connections matching a Trust access control rule on the first
packet generate different events depending on the presence of a Monitor
rule. If an active Monitor rule is present, the system generates both a
beginning and end-of-connection event, as expected. If no monitor rule is
active, the system does not generate a beginning-of-connection event.
(121060)
•
Do not name security zone objects using the pound sign (
#
); it may cause
errors during device reconfiguration. (121514)
•
If you attempt to break a stack that was registered using DNS during a
period when DNS is disabled, you will experience system issues. Do not
attempt this. (122709)
•
In some cases, intrusion event counts in the dashboard may not match the
counts in the event viewer. (122743, 123040, 122936)
•
When creating stacks of devices from different device groups, the
secondary device in the stack both retains membership in its original group
and becomes associated with the stack’s primary group. The user interface
does not alert the user to this behavior. (122802)
•
In some cases, your network discovery policy may not function as expected
if you apply two or more network discovery rules that apply to the same
zones and networks but are configured to discover different hosts, users,
and applications. (122853)
