The HardenedBSD project is engaged in an effort to improve the security of the FreeBSD operating system. The HardenedBSD fork gives developers an arena in which to test and improve security concepts, such as address space layout randomization (ASLR). The HardenedBSD developers have announced that their project now supports randomly positioning executables in memory, as well as their allocated memory. "We at HardenedBSD have added support in 11-CURRENT for compiling nearly all of base as Position-Independent Executables (PIEs, for short). This work bumps hardening.version to 45. We've enabled PIE base for amd64 and i386 and hope to enable it for arm64 before or during BSDCan 2016. Compiling an application as a PIE enables it to take full advantage of ASLR. Without PIE support, the application itself is loaded at a fixed address, determined at compile time. As of this writing, only nine applications are not compiled as PIEs."
