Different versions of Lucent Sky AVM might use different algorithms to calculate the hash of results. Hash value are used to identify results between different scans and applications, and to allow the suppression of results.
Result hash backward compatibility
Backward compatibility for suppression signatures is enabled by default, so a newer version of Lucent Sky AVM can recognize the suppression signatures generated by an earlier version. To disable this behavior, set SuppressionCompatibilityMode to false in the CLEAR Engine storage configuration file (also known as the cluster configuration file).
Result recurrence calculation does not support backward compatibility.
Result hash compatibility matrix
| Lucent Sky AVM version | Suppression signature compatibility | Result recurrence compatibility |
|---|---|---|
| 2003 and earlier | 2003 and earlier | 2003 and earlier |
| 2006 to 2009 | 2009 and earlier1, or 2006 and 20092 | 2006 and 2009 |
| 2103 to 2306 | 2306 and earlier1, or 2103 and later2 | 2103 to 2306 |
| 2309 to 25093 | 2103 and later4, or 2309 and later2 | 2309 and later |
| 2512 and later | 2309 and later5 | 2309 and later5 |
1. With suppression compatibility mode enabled.
2. With suppression compatibility mode disabled.
3. Hashes of dependency analysis results generated by version 2403 and earlier are incompatible with later versions.
4. With suppression compatibility mode enabled. Suppression compatibility mode is not applicable to some results.
5. Hashes of some results generated by version 2512 and later might differ than the hashes of the same results generated by earlier versions, therefore causing incompatibility of suppression signatures and result recurrence calculation for these results with earlier versions.
