Flow data

The flow data has been exported by a Cisco Catalyst 6500 with SUP2T supervisor module (PFC4, MSFC 5), and collected using nfcapd. Neither packet sampling nor flow sampling have been applied. The following post-processing operations have however been performed:

  1. Filtering: Only SSH data has been selected, i.e., the following nfdump filter has been used: port 22 and proto tcp.
  2. Anonymization: nfanon has been used for anonymizing the flow data in a prefix-preserving manner. More precisely, nfanon relies on the CryptoPAn (Cryptography-based Prefix-preserving Anonymization) module.
