usbguard VS itpol

You want USBGuard. Its probably available in your distro repository. Its a very neat piece of software!

If I were an attacker, could I clone the device id and attributes of the victim's previously approved devices? https://github.com/USBGuard/usbguard#before-the-first-start

Anyway I enjoy this HID stuff, I've been playing with using a computer as a keyboard to another computer. With scroll, num, and capslock LED's, bidirectional communication can be achieved and by injecting a small process I think some new kind of universal REPL can be accomplished.

Few days ago I found this: https://usbguard.github.io/ but during read some information how-to, I found comments similar to this: "A USB device can identify itself basically however it wants ". What's your opinion? USBGuard could be a tool, that nice to have or could be useless for some reason?

Hello lynet_101 I think that UsbGuard is what you are looking for: https://usbguard.github.io/

For those wondering, there is an easy defense against this on Linux, USBGuard (https://usbguard.github.io/)

RHEL7+ include USBGuard as part of the standard repo [0]

[0] https://access.redhat.com/documentation/en-us/red_hat_enterp...

Isn't UsbGuard designed to prevent exactly just that?

Not long before malware becomes more prevalent on Linux now that more people are using it. But Linux is not some magic bullet that stops all malware, you have to practice good opsec and harden your environment too. How to do this is outside the scope of my comment. If you are concerned though there are these resources:

Between the Arch wiki on Security and this link alone, there's enough inspiration to harden some stuff.

Linux hardening checklist Workstation security checklist

for workstation hardening, check out -- https://github.com/lfit/itpol/blob/master/linux-workstation-security.md

now, if you want a hardened workstation you should check out this -- https://github.com/lfit/itpol/blob/master/linux-workstation-security.md -- mind you, some of the data on here, like browsers and extensions/etc are out-dated but the general premise is pretty solid.

The Linux workstation security checklist would be a better recommendation. While also not targeted at home users, it gives at least some priority levels.
