Once again punishing the users abiding by the law, while rewarding the criminals. What’s new.

Now wondering what will happen with my 2 Mint Mobile numbers I’ve had for 3-4 years, without making a single phone call. I only use them for internet access.

My response to the other person kind of explains some of the things I do to keep my devices secure. As for what it means to me: being able to control everything to be able to define level of access. I try to treat every device on my network as though it’s already compromised. How can I block the scope of the devices from spreading on the network? How can I limit the scope of damage for what’s available on the compromised device to a minimum? Heavy firewall configurations help limit the devices spread to. Encrypting private data such as contracts, government docs, etc into their own containers or partitions helps limit leaks. Alerts and dashboards on unexpected changes of any devices allows me to react quickly, of automation hasn’t already reacted for me.

You’re right in the fact I’m not going to look at millions of lines of code for many tools and such I use. It doesn’t mean I don’t look though. Being given the option to look at what I’m running is always better to me than not having it, in my opinion

I have template iptables/nftables rules on my devices on the network that I can just copy and paste to a machine to have a firewall that works (with tweaks specific to that device). With it I can tell it to send all logs of my choice through syslog-ng to my server just by installing it and telling it the destination, allowing me to have (already made) alerts and dashboards on every device on my internal network. My router runs Linux (openwrt) and allows me to do something other routers can’t do because I’m able to add a module into the kernel: permit switch-level firewall access. What this means is I don’t need (but do still have) VLAN to restrict traffic between devices. I can block firewall access completely at the router level before a device is tweaked to also add additional security (e.g. helps prevent my smart tv from probing every device on my network to gather information. Or if I purchase a malicious hardware online, it won’t know the rest of the network exists because the router doesn’t tell it unless I say it’s okay).

That’s firewall stuff. System security: can compile and modify the kernel to just the modules and such I want, lowering the scope of issues from a kernel level vulnerability. I can be very granular with file and directory permissions with a single command in the terminal. I can easily track file metadata changes down to just about anything you can think of with simple tools, like aide. Python scripts through cron and inotify can help me monitor when something sus happens on my machines.

Most of all this being done on Windows or Mac would require extra effort to work correctly, and not to mention probably cost money for software that can do the same but isn’t free. Also not entirely sure a router can be setup on either of those OS.

“I hate when people keep repeating the myth that Linux is more secure than X OS without any understanding of how much Linux gets exploited.”

Very few operating systems are secure out of the box. It’s up to the users to make it secure. It just so happens to be that Linux is the easiest to make secure, therefore I’ve always seen it as such when done right. Not to mention, I can know exactly how everything works rather than the blackboxes of Win or Mac.
