Welcome

I have a dataset of type "CSV" named "NF" in which there is a column of type Categorecal named "Attack" and it has five categories: 'Benign', 'Theft', 'DDoS', 'DoS', and 'Reconnaissance' .

I want to extract a new dataset from this dataset "NF" based on the value of the column "Attack" if it is only equal to 'DDoS'
