A network attack is a nonnormal pattern of network use treated as an outlier or binary-classification target. Connection records may describe protocol, service, byte counts, login activity, file operations, and error rates. section 5.2.1
Common attack forms represented in the data include:
- Smurf attacks section 5.2.1
- Port sweeps section 5.2.1
- Buffer overflows section 5.2.1
KDD Cup connection records
The KDD Cup dataset labels each row as normal or an attack type. Its extreme imbalance—about 99.7% normal rows—supports evaluating detectors against rare attacks, while warning that detector performance depends on the data type. section 5.2.1
