Proper FreeBSD system hardning :)
(all for sysctl)

security.bsd.see_other_uids
security.bsd.see_other_gids
--> Don't show other users processes

security.bsd.unprivileged_read_msgbuf
--> Don't allow unprivileges to read kernel buffer (dmesg)

security.bsd.unprivileged_proc_debug
--> Don't allow unprivileged to use debugging

security.bsd.hardlink_check_uid
security.bsd.hardlink_check_gid
--> restrict hardlinks to same user/group

kern.elf64.aslr.enable
kern.elf32.aslr.enable
--> Enable kernel address randomization (ASLR)

security.bsd.unprivileged_mlock
--> Restrict unprivileged users from loading kernel modules

sysctl kern.securelevel=1
--> Cannot lower securelevel
--> Cannot write directly to mounted disks
--> Cannot write to /dev/mem or /dev/kmem
--> Cannot load/unload kernel modules
--> Cannot change firewall rules (if compiled with IPFIREWALL_STATIC)
--> System immutable and append-only file flags cannot be removed

This can make a FreeBSD system more secure, especially on multi-user systems. Securelevel ca even go higher, but those restrictions generally need care.

Thank you, @leanpub
!
I’m thrilled to see The Cybernetic Enterprise featured here. This book is all about how organizations can evolve into adaptive, learning systems. Combining AI, feedback loops, and platform thinking to thrive in constant change.

Many organizations expect #Frameworks to solve systemic issues—misaligned incentives, silos, lack of ownership. Marin Niehues discusses how value delivery depends on mindset, not rituals.

🎙️ When a 12-month waterfall plan fails… what happens next?

I joined Florian Schneider on Modern Work 2 Go to share lessons from a massive project that shifted from waterfall to full agile.

🔹 Only 1/3 of requirements mattered
🔹 Real progress came when biz + IT united
🔹 Agility = journey, not framework

Ellis and Blake are having a catch-up over a coffee. Ellis is looking a little stressed. “We hired a new product manage,” Ellis explains. “So we can be more user-centric.” “Great!” Blake responds. “How often will they speak to the users?” There’s a long silence, which gives Blake a disappointing answer to his question.

Arlo meets Murray in the corridor. Murray is looking happy and a little vacant. “I hear you do YBYR here?” Arlo asks to break the awkward silence. “What’s that?” Murray asks with a big smile on his face. “You build it, you run it,” Arlo answers. “Well,” Murray thinks. “Not really. It’s more like YBYF!”

I ask why security can’t be integrated into the teams, and why there isn’t enough supply for solving such an exciting and geeky part of the problem? Another audience member suggests the problem is the common bundling of security with compliance, but the personalities that thrive in those two tasks are extremely different.
