## Detection Level Tuning
|
||||
|

Hayabusa and Sigma rule authors will determine the risk level of the alert when writing their rules.
|
||||
However, the actual risk level will differ between environments.
|
||||
You can tune the risk level of the rules by adding them to `./config/level_tuning.txt` and executing `hayabusa.exe --level-tuning` which will update the `level` line in the rule file.
|

Please note that the rule file will be updated directly.

## Comparison To Other Similar Tools
|
||||
|
||||
Please understand that it is not possible to do a perfect comparison as results will differ based on the target sample data, command-line options, rule tuning, etc...
|
||||
In our tests, we have found hayabusa to support the largest number of sigma rules compared to other similar tools while still maintaining very fast speeds and does not require a great amount of memory.
|
||||
|
||||
The following benchmarks were taken on a Lenovo P51 based on approximately 500 evtx files (130MB) from our [sample-evtx repository](https://github.com/Yamato-Security/hayabusa-sample-evtx) at 2021/12/23 with hayabusa version 1.0.0.

|
||||
| Zircolite | 34 seconds | 380 MB (normally requires 3 times the size of the log files) | 237 |
|
||||
|
||||
* With hayabusa rules enabled, it will detect around 300 unique alerts and events.
|
||||
* When tested on many event logs files totaling 7.5 GB, it finished in under 7 minutes and used around 1 GB of memory. The amount of memory consumed is based on the size of the results, not on the size of the target evtx files.
|
||||
* It is the only tool that provides a consolidated single CSV timeline to analysis in tools like [Timeline Explorer](https://ericzimmerman.github.io/#!index.md).
