Here you can download last version of RPM packages for AppArmor. May be used on any CentOS7 machines.
Everything is checked for original kernels of kernel.org:
– 3.16.62 (kernel compiled via default config and ‘make pkg-rpm’)
Using of build-in kernel of CentOS7 with a lot of patches is not encouraged.
Always better to use original versions of kernels of own compilation (from kernel.org) for any important machines.
