 これは、必要なものだけを読み込むことで、スキャンを可能な限り効率的に行うことを目的としています。
 単一のイベントログ内に複数のプロバイダが存在することはありますが、単一の.evtxファイル内に複数のチャンネルが含まれることは一般的ではありません。

+As of Hayabusa v2.16.0, we enable a Channel-based filter when loading `.evtx` files and `.yml` rules.
 The purpose is to make scanning as efficient as possible by only loading what is necessary.
 While it possible for there to be multiple providers in a single event log, it is not common to have multiple channels inside a single evtx file.
 (The only time we have seen this is when someone has artifically merged two different evtx files together for the [sample-evtx](https://github.com/Yamato-Security/hayabusa-sample-evtx) project.)

 So for example, if a user wants to scan `Security.evtx`, only rules that specify `Channel: Security` will be used.
 There is no point in loading other detection rules, for example rules that only look for events in the `Application` log, etc...
 Note that channel fields (Ex: `Channel: Security`) are not **explicitly** defined inside original Sigma rules.
-For Sigma rules, channel and event IDs fields are **implicitly** defined with `service` and `category` fields under `logsource`. (Ex: service: security`)
-When curating Sigma rules in the [hayabusa-rules](https://github.com/Yamato-Security/hayabusa-rules) repository, we deabstract the `logsource` field and explicitly define the channel and event ID fields.

 If you want to use these two rules and scan all rules against loaded `.evtx` files then you will need to add the `-A, --enable-all-rules` option in the `csv-timeline` and `json-timeline` commands.
-In our benchmarks, the rules filtering usually gives a 20% to 10x speed improvement depending on what files are being scanned.
+In our benchmarks, the rules filtering usually gives a 20% to 10x speed improvement depending on what files are being scanned and of course uses less memory.
 
 Channel filtering is also used when loading `.evtx` files.
 For example, if you specify a rule that looks for events with a channel of `Security`, then there is no point in loading `.evtx` files that are not from the `Security` log.
