Method and system for checking integrity of Linux system

The invention relates to a method and a system for checking integrity of a Linux system. The method comprises the following steps of: verifying a file metadata modification behavior in the Linux system; performing integrity verification on the file metadata; updating the credible reference value of the file metadata; and auditing the operation behaviors to monitor and record the operation behaviors of the file metadata in the Linux system. The method has the advantages that the integrity of the file metadata in the Linux system is checked in time, and the influence of modification or damage of the file metadata on the Linux system is reduced. 本申请涉及一种Linux系统完整性检查方法与系统，其方法包括：对Linux系统中文件元数据修改行为进行验证；对文件元数据进行完整性验证；对文件元数据的可信基准值进行更新；对以上操作行为进行审计，用于监控和记录对Linux系统中文件元数据的操作行为。本申请具有及时对Linux系统中文件元数据进行完整性检查，降低文件元数据遭到修改或破坏对Linux系统产生的影响。
