The Talos Group provides updated rule sets for the Current Version and Prior Version of open source Snort available at www.snort.org. The following table depicts the versions of Snort supported by Talos under this Life Cycle Policy:
|Snort Version||Snort Certified Rule Set|
|Current Version||Updates Provided|
|Prior Version||Updates Provided*|
|Legacy Versions||Updates cease 90 days following the notification of EOL on the Snort blog. This will occur when fewer than 10% of the userbase is using this version or 5 years, whichever is first.|
*Rule updates for Prior Versions of Snort may not be identical to updates for the Current Version. Snort Subscriber Rules are developed to take advantages of the latest features in Snort. However Talos makes every effort to convert rules updates for supported Prior and Legacy Versions.
Once a new major production (stable) release of Snort is available at www.snort.org, that version now becomes the Current Version.
The following table illustrates the current Snort Subscriber Rule Set Lifecycle Policy:
|Snort 3.x.x.x||2021-01-19||TBD**||The nature of Snort 3 allows us to keep versions around for a bit longer, so we have not set EOL schedules on Snort 3 yet. This is subject to change.|
**TBD = To be determined
Cisco reserves the right to amend this policy at any time with or without notice.
