Security for Tablets

Does anyone know of a program equivalent to DeepFreeze that would work for a tablet? Or other ways of locking them down for security and privacy? I am soon to be in the position try and figure this out as much as possible due to my boss wanting to circulate them to library patrons.

Hello, i hope this is helpful.

Perhaps someone with hands on experience will also reply.
I did find these Alternatives

This also looked promising.. Creating a Steady State by Using Microsoft Technologies

It gives me more places to look.

Part of the problem is I'm learning about tablets myself still in some ways. I know generally you can essentially "reset" the device since much of them are account based - BUT I'm not convinced that does a whole lot against any sort of malware that might have made itself at home on the device.

Not familiar with DeepFreeze.
If the tablet is Android, there are few excellent products - Avast Mobile security, Dr.Web, Lookout and others.
Avast is free and includes AntiTheft.
The other two are free, but you need to get the paid version to have something equivalent to antiTheft.
As far as system misconfiguration - hard to do in Linux, but of course possible if you're rooted.
Avast also has a simple firewall, but requires admin rights, which in the Android language is called "rooting" = gain access to root, sort of like C:\Windows.

If your tablet is HTC, or Windows, or ... I have no idea, sorry.
