Encryption solid-state drive
Some models contain the Encryption solid-state drive. This feature helps to protect your tablet against
security attacks on media, NAND flash, or device controllers by use of a hardware encryption chip. For the
efficient use of the encryption feature, set a hard disk password for the internal storage device.
Using the security chip
Strict security requirements are imposed on network client computers that transfer confidential information
electronically. You can set the security chip in your tablet to enhance computing security. Some models
are equipped with one security chip called the firmware TPM (displayed as “Trusted Platform Module
2.0” in Device Manager). Some models are equipped with two security chips called the discrete TPM
(displayed as “Trusted Platform Module 1.2” in Device Manager) and the firmware TPM. For models with two
security chips, you can select which one you want to use in the ThinkPad Tablet Setup program by using
the instructions in this topic.
Note: Ensure that the supervisor password has been set in the ThinkPad Tablet Setup program; otherwise
anyone can change the settings for the security chip.

Internet security threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy.
For more information about how to use the firewall program, refer to the online help that comes with the
program.
