How to disable usb port on ASA 5525-X

[h.dam]

Hi everyone,

I would like to disable the usb port on the firewall in order to block physical access. But I didn't find the CLI command (ASA v9.8.1)

Having tried to search in this forum, people said it is impossible to do.

Did someone succeed to do it?

Thanks.

Regards.

I've already tried this.

This command is not recognized.

I have inserted a usb key with FAT format on one usb port (below the mngt port), nothing happened. 

When I run the command DIR, I saw only disk0.

Can you state here your HW and SW version pleasE?
Also you want to enable or disable USB port?

Hi Florin,

The firewall is ASA 5525-X with v9.8(1).

I'd like to disable the usb key as said on the title.

But I cannot disable it if I don't see disk1.

Regards.

By default the "dir" command will only show you disk0 (internal compact flash card).

If a FAT-formatted USB storage device is connected to the external USB port, you should be able to see its contents with "dir disk1:"

You cannot disable the ASA USB port in software. If you order the FIPS kit it will include a set of tamper resistant stickers - you can apply one of those over the physical port to prevent/detect its use. You can also disable access to it it physically - I have seen epoxy used to fill the port in high security environments!

Thank you for your response.

I don't know what are the uses of these usb ports designed originally.

Especially on a security appliance where physical access is not permitted in most cases.

So I have to put sticker on it. Sorry that I have no other choice.
