Security management
System security is of primary concern for many end users,
particularly those individuals and IT departments working within
the corporate environment. Loss of any kind, whether loss of
hardware or loss of sensitive data, directly impacts the profitability
of any business. Security concerns revolve around two major
challenges:
❖
Ensuring that data is secure from loss or external tampering
❖
Ensuring that computers and/or components are secure from
theft
Types and levels of security that protect against data or hardware
loss or theft are described in this section.
System password in Flash, Not CMOS
Toshiba addresses security concerns in a number of ways. Across
Toshiba’s product lines, the system password for user entry is
located in flash memory, as opposed to CMOS. CMOS is battery-
powered memory. If the small CMOS battery is shorted or runs
down, the password is deleted and the system is left vulnerable to
external violation. FLASH memory is non-volatile ROM memory
and is not susceptible to power loss, either inadvertent or
intentional. Writing the password into FLASH memory protects
the security of the system, ultimately protecting both hardware and
sensitive data.
Supervisor password
Each Toshiba system has the capability of utilizing two passwords
for added security and investment protection: the user password
and the supervisor password. The supervisor password, if enabled,
carries a higher priority than the user password. In the event that an
employee forgets his or her password or leaves the company
without divulging the system password, the supervisor password
