使用 OpenScap 进行 CIS 基准测试

我正在尝试使用 openscap 运行 CIS Centos 6 基准测试。但是它不起作用。我这样调用它：

oscap oval eval  /var/tmp/cis-cat-full/benchmarks/CIS_CentOS_Linux_6_Benchmark_v2.0.1-oval.xml

产生大量的输出，例如

File '/var/tmp/cis-cat-full/benchmarks/CIS_CentOS_Linux_6_Benchmark_v2.0.1-oval.xml' line 8464: Element '{http://oval.mitre.org/XMLSchema/oval-definitions-5}object_component': No match found for key-sequence ['oval:org.cisecurity.benchmarks.o_centos_centos:obj:10389'] of keyref '{http://oval.mitre.org/XMLSchema/oval-definitions-5}objectKeyRef'.

OpenSCAP Error: Invalid OVAL Definition (5.11) content in /var/tmp/cis-cat-full/benchmarks/CIS_CentOS_Linux_6_Benchmark_v2.0.1-oval.xml. [oscap_source.c:268]

我尝试用解决这个问题--skip-valid，但这也无济于事：

oscap oval eval --skip-valid /var/tmp/cis-cat-full/benchmarks/CIS_CentOS_Linux_6_Benchmark_v2.0.1-oval.xml 
OpenSCAP Error: Unknown test type oval:org.cisecurity.benchmarks.o_centos_centos:tst:10003. [oval_test.c:402]
Failed to import the OVAL Definitions from '/var/tmp/cis-cat-full/benchmarks/CIS_CentOS_Linux_6_Benchmark_v2.0.1-oval.xml'. [oval_session.c:238]

是否有人使用 openscap 运行 CIS 基准测试的经验？如果有，那么它是如何工作的？

答案1

我是一名 OpenSCAP 开发人员。我们使用 MITRE 和 CIS 提供的官方 XML 模式。从消息来看，您收到的 OVAL 文件似乎不是有效的 OVAL 5.11 文件。

您可以使用 --skip-valid 解决此问题，但更好的解决方案是将此问题报告给 CIS 并修复它。

答案2

Openscap 1.3.4 似乎没有 AIX interim_fix 功能，这导致无法运行 CIS unix.xml 椭圆文件。

添加以下几行并构建源代码将修复该问题并忽略 interim_fix 测试

文件：src/oval_enumerations.c

{OVAL_AIX_INTERIM_FIX, "interim_fix"},
{OVAL_AIX_NO, "no"},
