A secured message indicates that a node ( 104 ) in a network ( 102 ) is operating correctly and detecting that the node is compromised such that a device ( 106 ) should not communicate with the node. When the node is detected to be compromised, the secured message ceases to be transmitted to the node and the device. The secured message may include a time stamp portion and a security portion. A secured timestamp server ( 110 ) includes a transceiver ( 202 ) that receives notifications from a network management server ( 108 ) and transmits secured messages for use by the device. A processor ( 204 ) provides the secured message with a time stamp portion and a security portion when notifications indicate a node in the network is properly operating and ceases the transmission of the secured message when notifications indicate that the node is compromised.
