Subject: DV Toolkit filter overrides

Date of Announcement: September 27, 2016

Affected Versions: v3.1 and v3.1.1

An issue has been identified in the behavior of DV Toolkit v3.1 and v3.1.1 in which migrating to these versions and on certain use cases can cause the previous DVT filter overrides to be lost.

These use cases include:

• Renumbering a DV Toolkit package.
• Migrating a DVT package generated in DV Toolkit v3.0 or earlier to this newer version of DV Toolkit.

After a user performs these types of operations, then imports and activates the new DVT package, the SMS or the LSM will treat all filters in that DVT package as new. This means the filter overrides for all DVT filters in that package may revert to their default, disabled state without visual notification or prompting.

These changes can be verified by checking the SMS/IPS audit logs which will show that all filter overrides and original DV Toolkit filters have been deleted, and that the filters in the reimported package have been added.

Recommended Actions

• If you are not using the new enhancements introduced in DV Toolkit 3.1 or 3.1.1, we recommend using DV Toolkit 3.0, until a new DV Toolkit is released.
• If you continue to use DV Toolkit 3.1 or 3.1.1 Trend Micro TippingPoint recommends that the filter overrides on DVT filters be reviewed.
• Customers using DV Toolkit 3.0 or earlier are not affected.

An update to DV Toolkit to correct the behavior is being qualified, and will be published as soon as possible.

If you have concerns or further questions regarding this issue, contact the Trend Micro TippingPoint Technical Assistance Center (TAC).
