Configure Microarchitectural Data Sampling mitigation
Microarchitectural Data Sampling (MDS) is a hardware vulnerability which allows unprivileged speculative access to data which is available in various CPU internal buffers. When performing store, l...Rule Medium Severity -
Enable randomization of the page allocator
To enable randomization of the page allocator in the kernel, add the <code>page_alloc.shuffle=1</code> argument to the default GRUB 2 command line. To ensure that <code>page_alloc.shuffle=1</code> ...Rule Medium Severity -
Enable Kernel Page-Table Isolation (KPTI)
To enable Kernel page-table isolation, add the argument <code>pti=on</code> to the default GRUB 2 command line for the Linux operating system. To ensure that <code>pti=on</code> is added as a kerne...Rule Low Severity -
Configure the confidence in TPM for entropy
The TPM security chip that is available in most modern systems has a hardware RNG. It is also used to feed the entropy pool, but generally not credited entropy. Use <code>rng_core.default_quality<...Rule Low Severity -
Disable merging of slabs with similar size
The kernel may merge similar slabs together to reduce overhead and increase cache hotness of objects. Disabling merging of slabs keeps the slabs separate and reduces the risk of kernel heap overflo...Rule Medium Severity
