Systems and methods for enhancing the Connectivity Fault Management (CFM) protocol defined in IEEE 802.1Q are provided. In particular, the enhancements include adding a security or safety feature to prevent malicious attacks. A method, according to one implementation, includes the step of operating a Network Element (NE) in a safety mode associated with a link connectivity protocol (e.g., CFM) that involves receiving one or more messages used for detecting link connectivity issues of an Ethernet service in a section of a network and responding to the link connectivity issues. In response to receiving the one or more messages used for detecting link connectivity issues while operating the NE in the safety mode, the method includes the step of storing the one or more messages as one or more untrusted messages in an isolated database of the NE without processing information in the one or more untrusted messages.
