基于OSSIM平台下华为交换机日志收集插件的开发

长期以来，大家在收集华为交换机日志是往往通过syslog协议转发的方式，将华为交换机日志转发到日志收集器上，简单存储，但这样并没有将日志标准化，也就是OSSIM中对日志的归一化处理，在《开源安全运维平台－OSSIM最佳实践》一书的第七章专门讲解了日志收集与插件的自定义，本文将继续本书内容，为大家分享华为交换机插件，根据书中讲解，我们在OSSIM Agent插件目录中建立插件名称,huawei.cfg，编写插件大致格式可按书里面内容编写，不过还需要注意插件的导入过程，下面举个华为插件的实际例子。

完成插件编写之后就要进行反复测试与修改，待测试通过后就要进行插件导入工作，最后是插件启用,如下图所示。
