Security Feature Settings
When setting IPsec/IP filtering or IEEE802.1X, it is recommended that you access Web Config using SSL/TLS to
communicate settings information in order to reduce security risks such as tampering or interception.
Also, you can use Web Config by connecting the printer directly to the computer using an Ethernet cable, and then
entering the IP address into a web browser. The printer can be connected in a secure environment after the security
settings have been completed.
Making Settings for Password Encryption
Password encryption allows you to encrypt confidential information (all passwords, certificate private keys, hard
disk authentication keys) stored in the printer. The encryption key for decrypting encrypted confidential
information is stored in the TPM (Trusted Platform Module) chip. Since the TPM chip is not accessible from
outside the printer, you can protect encrypted confidential information without sharing the encryption key.
c
Important:
If the TPM chip fails and the encryption key cannot be used, you cannot restore the confidential information in the
printer and use the printer. Therefore, make sure to back up your encryption key to a USB memory.
Encrypting the Password
When you want to encrypt the password, you need to back up the encryption key. Prepare a USB memory for
backup in advance. You need 1 MB or more free space in the USB memory.
c
Important:
When replacing the TPM chip, you need a USB memory that contains the encryption key. Store this in a safe place.
