The web content details the implementation of various security settings inspired by the Kernel Self Protection Project (KSPP). It restricts certain system calls, randomizes addresses to prevent vulnerabilities, enables memory zeroing, and implements kernel page table isolation to mitigate Meltdown. Additionally, it enhances privacy settings for Bluetooth connections, improves entropy collection, restricts root access, and protects against brute force attacks. Moreover, the content includes information on restrictive mount options, restrictions on kernel modules, and access rights restrictions. Surprisingly, it also discusses application-specific hardening techniques for popular software like Thunderbird. Lastly, it highlights the importance of BIOS and GRUB password protection and disk encryption.
