Qlog Windows安全日志分析工具：全面保护系统安全，深度挖掘日志数据

关于Qlog

Qlog是一款功能强大的Windows安全日志工具，该工具可以为Windows操作系统上的安全相关事件提供丰富的事件日志记录功能。该工具目前仍处于积极开发状态，当前版本为Alpha版本。Qlog没有使用API钩子技术，也不需要在目标系统上安装驱动程序，Qlog指挥使用ETW检索遥测数据。当前版本的Qlog仅支持“进程创建”事件，之后还会添加更多丰富的事件支持。Qlog可以看作为Windows服务运行，但也可以在控制台模式下运行，因此我们可以将丰富的事件信息直接传输到控制台进行处理。

工作机制

Qlog可以从ETW读取数据，并将丰富的事件信息写入Qlog的事件通道，工具将会创建并使用名为“QMonitor”的新事件源，并写入Windows事件日志中。

以下是Qlog的事件处理顺序：

• 创建ETW会话，并订阅相关内核和用户区ETW Provider;
• 从ETW提供程序读取事件;
• 丰富的事件支持;
• 将丰富的事件写入事件日志通道QLOG;

工具依赖&安装&使用

Qlog的运行需要在本地系统中安装并配置好.NET Framework >= 4.7.2环境。

接下来，我们需要使用下列命令将该项目克隆至本地：

1. gitclonehttps://github.com/threathunters-io/QLOG.git

接下来，我们可以使用下列命令以交互式终端模式运行Qlog：

1. qlog.exe

或者，以Windows服务的方式运行：

1. #安装服务
3. qlog.exe-i
5. #卸载服务
7. qlog.exe-u

进程处理事件数据输出
