Helping people with computers... one answer at a time.
Mobile security is important. There are several things you'll want to do to secure your hotspot.
What's the best practice configuration for mobile hotspots? For example, the Verizon 4G LTE 890L jet pack. Is it possible or recommended to change the password that appears on the underside of the device? Should I change the SSID? I have several of these units and must ensure the utmost security.
In this excerpt from Answercast #60, I look at the necessary security steps to take with mobile hotspots.
Well, there are definitely several things you want to do with each one of those devices.
I'm not really not that concerned about changing the SSID. I would recommend that you do so mostly for your convenience, simply so that you have an SSID that you can recognize when you see it over the air.
I carry a cellular phone that falls into this same category. It's a mobile hotspot that I can turn on. And yeah, I have my own SSID (it's called Ask Leo! surprisingly enough), but that doesn't add a layer of security by any stretch.
What does though are the two things that you've just recommended. Definitely change the administrative password that appears on the underside of the device.
What it boils down to is that anybody who could see the underside of the device even briefly (maybe long enough to take a picture of it) could get the administrative password to the hotspot.
That's not something you want somebody else to have. So, change it to something else. Change it to something that you know you will remember, and that you can use then to administer the rest of the settings on that mobile device.
Similarly, the other thing that you happened to mention that I would strongly recommend you do is:
Make sure that the wireless hotspot is configured to only accept connections using WPA2 security;
And that that security have an appropriately complex or secure password.
That is probably the most important part of the configuration of this device. That's what secures the actual conversation between the device and the computers nearby. It prevents anybody within range from randomly snooping on the conversations and potentially sniffing sensitive data that's going across that wireless connection.
Change the administrative password, absolutely!
Make sure you're using WPA2 security for the wireless connection itself.
Set an SSID, if you like. It can be something convenient, but don't think that it adds any security.
And for the record, this applies not only to mobile hotspots - like the dedicated devices you're talking about. The little Mi-Fi kind of devices are stand-alone but this absolutely applies to cellular phones - smartphones that themselves that can be turned into wireless hotspots by running an appropriate application.
Make sure that the administrative password (if there is one) is set
appropriately. Make sure that the Wi-Fi connection itself is similarly
configured to use WPA2 with an appropriately secure password.
