Security Issues in Network Event Logging (syslog) ------------------------------------------------- Charter Last Modified: 2010-05-05 Current Status: Active Working Group Chair(s): Chris Lonvick David Harrington Security Area Director(s): Sean Turner Tim Polk Security Area Advisor: Sean Turner Mailing Lists: General Discussion:syslog@ietf.org To Subscribe: syslog-request@ietf.org In Body: in body: (un)subscribe Archive: http://www.ietf.org/mail-archive/web/syslog Description of Working Group: Syslog has been a de-facto standard for logging system events for long time. The syslog WG recently completed standardization of the syslog protocol (RFC 5424), secure transport of the syslog protocol over TLS (RFC 5425), and non-secure transport over UDP (RFC 5426). The WG under this charter will standardize a DTLS transport for syslog, providing a secure transport for syslog messages in cases where a connection-less transport is desired. The threats that this WG will primarily address are modification, disclosure, and masquerade. A secondary threat is message stream modification. These are consistent with those addressed in RFC 5425. Draft-feng-syslog-transport-dtls is already similar to RFC 5425 in this respect, so this draft will become the starting point for the WG document, which the WG will adjust as needed, and merge desired features from other sources, such as draft-petch-gerhards-syslog-transport-dtls, draft-hardaker-isms-dtls-tm, and draft-seggelmann-tls-dtls-heartbeat. The WG will also complete the ongoing work to specify a standardized mechanism for signing syslog messages (draft-ietf-syslog-sign). Goals and Milestones: Done Post as an Internet Draft the observed behavior of the Syslog protocol for consideration as an Informational Document. Done Submit Syslog protocol document to IESG for consideration as an INFORMATIONAL RFC. Done Post as an Internet Draft the specification for an authenticated Syslog for consideration as a Standards Track RFC. Done Post an Internet Draft describing enhancements to the Syslog authentication protocol to add verification of delivery and other security services. Done Submit Syslog Authentication Protocol Enhancement to IESG for consideration as a PROPOSED STANDARD. Done Submit Syslog UDP Transport Mapping to the IESG for consideration as a PROPOSED STANDARD Done Submit Syslog Protocol to the IESG for consideration as a PROPOSED STANDARD Done Submit Syslog TLS Transport Mapping to the IESG for consideration as a PROPOSED STANDARD Done Submit a document that defines a message signing and ordering mechanism to the IESG for consideration as a PROPOSED STANDARD Done Submit Syslog DTLS Transport Mapping to the IESG for consideration as a PROPOSED STANDARD Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- Oct 2009 Jul 2010 Datagram Transport Layer Security (DTLS) Transport Mapping for Syslog Request For Comments: RFC Stat Published Title ------- -- ----------- ------------------------------------ RFC3164 I Aug 2001 The BSD Syslog Protocol RFC3195 PS Nov 2001 Reliable Delivery for Syslog RFC5426 PS Mar 2009 Transmission of Syslog Messages over UDP RFC5425 PS Mar 2009 Transport Layer Security (TLS) Transport Mapping for Syslog RFC5424 PS Mar 2009 The Syslog Protocol RFC5427 PS Mar 2009 Textual Conventions for Syslog Management RFC5848 PS May 2010 Signed Syslog Messages
