🔐 Tired of bloated `sshd_config` files?
💡 Try modular SSH policies!

Our latest guide shows how to group SSH settings into reusable policy files using `Include`. Tackle brute-force attacks (like CVE-2024-6387), disable forwarding, enforce key-only logins, and apply IP-based rules.

🛠️ Cleaner configs = better security & scalability.

Did you know the NSA built one of the best Linux security tools—and the FOSS community made it trustworthy?

That tool is SELinux.

This write-up explains:

What SELinux really does

How it labels and controls everything—even root

Why turning it off is a bad habit (and what to do instead)

Tried integrating ROS2 on Oracle Linux with SELinux—no go.
Switched to AppArmor on Ubuntu—easier, yes. Effective? Not quite.

colcon and AppArmor don’t play well together. Turns out, AppArmor’s simplicity can limit it in complex dev environments.

Here’s my story, what didn’t work, and where I’m heading next:

Boosts appreciated if you think secure ROS2 needs better tooling. 🧵
