RFC 9742: A YANG Data Model for Syslog Management
Proposed Standard- J. Clarke
- M. Jethanandani
- C. Wildes
- K. Koushik
- April 2025

RFC 9662: Updates to the Cipher Suites in Secure Syslog
Proposed Standard- C. Lonvick
- S. Turner
- J. Salowey
- October 2024
- IETF publication
- Security Area
Abstract
RFCs 5425 and 6012 describe using TLS and DTLS to securely transport syslog messages. This document updates the cipher suites required by RFC 5245 (TLS Transport Mapping for Syslog) and RFC 6012 (DTLS Transport Mapping for Syslog). It also updates the protocol recommended by RFC 6012 for secure datagram transport.

RFC 6587: Transmission of Syslog Messages over TCP
Historic- R. Gerhards
- C. Lonvick
- April 2012
- IETF publication
Abstract
There have been many implementations and deployments of legacy syslog over TCP for many years. That protocol has evolved without being standardized and has proven to be quite interoperable in practice. This memo describes how TCP has been used as a transport for syslog messages. This document defines a Historic Document for the Internet community.

RFC 6012: Datagram Transport Layer Security (DTLS) Transport Mapping for Syslog
Proposed Standard- J. Salowey
- T. Petch
- R. Gerhards
- H. Feng
- October 2010
- IETF publication
- Security Area
Abstract
This document describes the transport of syslog messages over the Datagram Transport Layer Security (DTLS) protocol. It provides a secure transport for syslog messages in cases where a connectionless transport is desired.

RFC 5848: Signed Syslog Messages
Proposed Standard- J. Kelsey
- J. Callas
- A. Clemm
- May 2010
- IETF publication
- Security Area
Abstract
This document describes a mechanism to add origin authentication, message integrity, replay resistance, message sequencing, and detection of missing messages to the transmitted syslog messages. This specification is intended to be used in conjunction with the work defined in RFC 5424, "The Syslog Protocol". [STANDARDS-TRACK]

RFC 5674: Alarms in Syslog
Proposed Standard- S. Chisholm
- R. Gerhards
- October 2009
- IETF publication
- Operations and Management Area
Abstract
This document describes how to send alarm information in syslog. It includes the mapping of ITU perceived severities onto syslog message fields. It also includes a number of alarm-specific SD-PARAM definitions from X.733 and the IETF Alarm MIB. [STANDARDS-TRACK]

RFC 5676: Definitions of Managed Objects for Mapping SYSLOG Messages to Simple Network Management Protocol (SNMP) Notifications
Proposed Standard- J. Schoenwaelder
- A. Clemm
- A. Karmakar
- October 2009
- IETF publication
- Operations and Management Area
Abstract
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a mapping of SYSLOG messages to Simple Network Management Protocol (SNMP) notifications. [STANDARDS-TRACK]

RFC 5427: Textual Conventions for Syslog Management
Proposed Standard- G. Keeni
- March 2009
- IETF publication
- Security Area
Abstract
This MIB module defines textual conventions to represent Facility and Severity information commonly used in syslog messages. The intent is that these textual conventions will be imported and used in MIB modules that would otherwise define their own representations. [STANDARDS-TRACK]

RFC 5424: The Syslog Protocol
Proposed Standard- R. Gerhards
- March 2009
- IETF publication
- Security Area
Abstract
This document describes the syslog protocol, which is used to convey event notification messages. This protocol utilizes a layered architecture, which allows the use of any number of transport protocols for transmission of syslog messages. It also provides a message format that allows vendor-specific extensions to be provided in a structured way.
This document has been written with the original design goals for traditional syslog in mind. The need for a new layered specification has arisen because standardization efforts for reliable and secure syslog extensions suffer from the lack of a Standards-Track and transport-independent RFC. Without this document, each other standard needs to define its own syslog packet format and transport mechanism, which over time will introduce subtle compatibility issues. This document tries to provide a foundation that syslog extensions can build on. This layered architecture approach also provides a solid basis that allows code to be written once for each syslog feature rather than once for each transport. [STANDARDS-TRACK]

RFC 5425: Transport Layer Security (TLS) Transport Mapping for Syslog
Proposed Standard- F. Miao
- Y. Ma
- J. Salowey
- March 2009
- IETF publication
- Security Area
Abstract
This document describes the use of Transport Layer Security (TLS) to provide a secure connection for the transport of syslog messages. This document describes the security threats to syslog and how TLS can be used to counter such threats.

RFC 5426: Transmission of Syslog Messages over UDP
Proposed Standard- A. Okmianski
- March 2009
- IETF publication
- Security Area
Abstract
This document describes the transport for syslog messages over UDP/ IPv4 or UDP/IPv6. The syslog protocol layered architecture provides for support of any number of transport mappings. However, for interoperability purposes, syslog protocol implementers are required to support this transport mapping. [STANDARDS-TRACK]

Abstract
The BSD Syslog Protocol describes a number of service options related to propagating event messages. This memo describes two mappings of the syslog protocol to TCP connections, both useful for reliable delivery of event messages. [STANDARDS-TRACK]
