The Sourcefire Vulnerability Research Team (VRT) 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 the VRT under this Life Cycle Policy:
|Snort Version||VRT Certified Rules|
|Current Version||Updates Provided|
|Prior Version||Updates Provided*|
|Legacy Versions||Updates cease 90 days following the release date of the Current Version*|
*Rule updates for Prior Versions of Snort may not be identical to updates for the Current Version. VRT Certified Rules are developed to take advantages of the latest features in Snort. However the VRT 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 VRT Certified Rules Lifecycle Policy:
