For example \x20 would translate to a single space. \x To allow a single-byte hex-encoded sequence.\' For a single quote within the quotes.To escape special characters within the single quotes, the following sequences are supported: For searches with non-alphanumeric values or spaces, enclose the value in single quotes. Property values can be an integer, a simple alphanumeric string, or they can be more complex and include other characters, such as spaces, backslashes, and hex-encoded values. You cannot have more than 55 unique terms in a Signal. Not all conditions are supported with all object properties. The condition specifies how the object and property relate to the value provided. object.property condition 'value with spaces'Įach object is a type of process event and has one or more properties that narrow the scope of the event.Write Signal expression in one of the following formats: A Signal can have multiple expressions in a single definition, connected with AND or OR operators. For example, a file object is an operation on a file by a process. The objects reference process-related events. One or more expressions make up the Signal definition. The syntax of Signals are built from the supported objects, properties, conditions, and the search values into search expressions. Threat Response regularly polls the endpoints with a saved question to gather alerts that are written to the Alerts page. Whenever a Signal condition is matched, a finding is generated. Each event gets evaluated against any Signal definitions. Unlike other types of intel, the recorder continuously inspects each process creation event in real time and Threat Response reports a finding when a match occurs, rather than performing periodic scans. The Signals are compiled, then sent and applied to the appropriate computer groups. Like other intel, Signals get validated when they are added to the Threat Response service to ensure proper structure. Signals use a specific language syntax to build search expressions for process-related events on the endpoint. A narrow search scope helps you minimize false-positive alerts. With Signals you can detect suspicious or interesting process behavior by combining multiple search expressions. Signals are available as a feed from Tanium, or you can author your own Signals that are specific to your environment.įor Tanium Cloud customers, Tanium collects and uses metadata to continually improve the effectiveness of Signals. You can use Signals for the continuous, real-time evaluation of process, network, registry (Windows only), and file events on endpoints.
