Sophos UTM devices are firewall/VPN devices that provide controlled connectivity between an internal network and an external network (internet) while providing protection for the internal network by blocking traffic that isn’t explicitly allowed.
The VPN functionality allows encrypted external connections to the internal network by pre-configured authenticated users. Sophos UTM devices can be configured to provide additional security functions as well. CimTrak for Network Devices monitors the device configuration for changes, logs the changes, and then notifies the responsible parties of them
When CimTrak locks a Sophos UTM device for monitoring, it reads the configuration of the device. It calculates a digital signature for the configuration, and store it in CimTrak’s master repository along with a copy of the configuration.
When CimTrak detects a change in the configuration, that configuration and its digital signature
CimTrak detects any change to the Sophos UTM device’s configuration.
