5.2.3.18 Security
The security concept of the R&S SMB helps you to protect your instrument against
uncontrolled access and changes. All provided security services require that you enter
the security password.
Provided security services are:
●
Password management secures controlled user access to the instrument
With the two-step password concept, you can assign a user-defined password for
the operating system, as well as a security password for accessing the mass stor-
age of the instrument.
For more information concerning the security password, see the description
Resolving Security Issues when Working with an R&S SMB . You can find this
document on the R&S SMB product page at "Downloads" > "Manuals".
●
LAN Services secures controlled network access.
You can individually lock and unlock the supported LAN interface services, see
"LAN Services" on page 116.
Remote control via LAN interface requires that the interface is activated, but you

– USB Storage secures controlled access to the mass memory of the instru-
ment.

the file system.
