 """ Updates security marks. Example: Args: security_marks (Union[dict, ~google.cloud.securitycenter_v1.types.SecurityMarks]):
 The security marks resource to update. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.securitycenter_v1.types.SecurityMarks` update_mask (Union[dict, ~google.cloud.securitycenter_v1.types.FieldMask]):
 The FieldMask to use when updating the security marks resource. The field mask must not contain duplicate fields. If empty or set to "marks", all marks will be replaced. Individual marks can be updated using "marks.<mark\_key>". If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.securitycenter_v1.types.FieldMask` start_time (Union[dict, ~google.cloud.securitycenter_v1.types.Timestamp]):
 The time at which the updated SecurityMarks take effect. If not set uses current server time. Updates will be applied to the SecurityMarks that are active immediately preceding this time. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.securitycenter_v1.types.Timestamp` retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.securitycenter_v1.types.SecurityMarks` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
