1 Select Security Level
The operating system of
your CryptoPhone has been
hardened against a num-
ber of known attacks.
To make use of this protec-
tion mechanism, the first
step to configure your
CryptoPhone before you
take it in use, is to select
the operating sys-
tem’s security level
in the Security
Profile Manager
tool (this does
not influence the
security of en-
crypted telephony
or SMS).
To reduce the
likelihood of new
and unknown attacks impacting
the security of your phone, the
higher security levels disable
more applications and services
than the lower security levels.
Setting the system’s security
level thus enables you to choose
the right balance between con-
venience and security by remov-
ing more potentially vulnerable
components and capabilities in
the higher security levels. Please
read the description of each se-
curity level carefully and choose
the level most appropriate for
you.
The default security level is
High. While you can always
switch to a different security
level later by cold booting the
phone (
see
section
13
), doing so
will erase all data stored on the
phone.
