  1. Internet facing serverlogging recommendation Alain Durand, Juniper networks

  2. Background • The IPv4 IANA free pool will soon be exhausted • ISPs around the world will be deploying NATs • Draft-ietf-intarea-shared-addressing-issues explains the issues around logging to deal with abuse/LEA • Logs on the NAT side need to be matched with logs on the server side • Need more specific information on the server side logs than we currently have.

  3. Recommendation (BCP candidate) • It is RECOMMENDED as best current practice that Internet facing servers logging incoming IP addresses also log: • The source port number. • A timestamp accurate to the second, with associated time zone. • The transport protocol (usually TCP or UDP) and destination port number, when the server application is defined to use multiple transports or multiple ports.
