AWS Flow Logs provide ‘Cisco Netflow-like’ data about the IP traffic traversing your AWS estate (your AWS VPC). VPC Flow Logs provide data on:
Source and destination IP addresses and ports
Protocol, sent packet and byte counts
Interface and AWS accountID
Allowed or Denied indicator
Number of packets and bytes transferred
Start and end time
VPC Flow Logs are processed by LANGuardian, generating similar metadata to NetFlow. The VPC Flow Logs are merged into sessions, GeoLocation information is added and saved into the NetFort database.
