  1. draft-ietf-syslog-transport-udp Internet Draft 00 Anton Okmianskiaokmians@cisco.com

  2. Overview • Standards Track Internet Draft • Replaces informational RFC3164 • Defines UDP transport for syslog-protocol Internet Draft • Syslog clients and servers MUST support UDP transport • Defines UDP server port as 514

  3. Transport • One datagram per syslog message • One datagram per syslog message part for multi-part syslog messages • UDP checksums RECOMMENDED • IP fragmentation SHOULD be avoided • Recommends syslog payload of no more than 548 bytes to avoid fragmentation

  4. Reliability Considerations • Lost datagrams • Corrupted datagrams • No congestion control • No sequenced delivery • IP fragmentation increase risk of datagram loss

  5. Security Considerations • No message authenticity • No strong authentication • Message forgery possible • Message observation possible • Replay attacks possible • Issues due to lack of reliability • No prioritization • Denial of service possible • Covert channels possible
