Hi Vinoth,

The IDS-4215 sensor does not support the IPS 7.0 software version. The latest software version supported on this platform is 6.0.

It does however support the E4 engine in combination with the 6.0(6) software version.

In order to upgrade your sensor to  the E4 engine (and use the latest signatures), upgrade it with the 6.0(6)E4 software package pkg file.

You can download this upgrade from the below link:

If you are currently running the 6.0 version, you will just need the "                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             IPS-engine-E4-req-6.0-6.pkg" file to upgrade the engine, if you are on an earlier software version, you will need to download "IPS-K9-6.0-6-E4.pkg"

Make sure to read the readme before upgrading:
