Environment
- Cb Defense Web Console: All Versions
- Cb Defense Sensor: 2.0.2.x+ (Windows)
- Microsoft Windows: All Supported Versions
- Mirror Server set up
Symptoms
- Local Scan enabled
- Policy set to download from Local Mirror
- Cb mirror removed from policy/unchecked
- Local Mirror unavailable
- Sensor downloads signature update from Cb Mirror
Cause
The current design is such that the sensor always attempts to download from cloud even if Cb Mirror has been unchecked from policy.
Resolution
- Create internal firewall rule to block sensors from reaching out to the cloud for updates
- Only allow the mirror server(s) to reach to the cloud for update
- Create a secondary mirror server to act as a backup if the main fails
- select which you prefer as master in the policy
