10.6 Internal TOE TSF data transfer (FPT_ITT)

Family behaviour

This family provides requirements that address protection of TSF data when it is transferred between separate parts of a TOE across an internal channel.

Component levelling

FPT_ITT.1 Basic internal TSF data transfer protection, requires that TSF data be protected when transmitted between separate parts of the TOE.

FPT_ITT.2 TSF data transfer separation, requires that the TSF separate user data from TSF data during transmission.

FPT_ITT.3 TSF data integrity monitoring, requires that the TSF data transmitted between separate parts of the TOE is monitored for identified integrity errors.

Management: FPT_ITT.1

The following actions could be considered for the management functions in FMT:

a)    management of the types of modification against which the TSF should protect;

b)    management of the mechanism used to provide the protection of the data in transit between different parts of the TSF.

Management: FPT_ITT.2

The following actions could be considered for the management functions in FMT:

a)    management of the types of modification against which the TSF should protect;

b)    management of the mechanism used to provide the protection of the data in transit between different parts of the TSF;

c)    management of the separation mechanism.

Management: FPT_ITT.3

The following actions could be considered for the management functions in FMT:

a)    management of the types of modification against which the TSF should protect;

b)    management of the mechanism used to provide the protection of the data in transit between different parts of the TSF;

c)    management of the types of modification of TSF data the TSF should try to detect;

d)    management of the actions that will be taken.

Audit: FPT_ITT.1, FPT_ITT.2

There are no actions identified that should be auditable if FAU_GEN Security audit data generation is included in the PP/ST.

Audit: FPT_ITT.3

The following actions should be auditable if FAU_GEN Security audit data generation is included in the PP / ST:

a)    Minimal: the detection of modification of TSF data;

b)    Basic: the action taken following detection of an integrity error.
