Introduction
Consumer mobile devices like smartphones are becoming the entrance to digital services, such as mobile banking,
electronic identity verification, digital key management, etc. Preloaded applications installed on the device provide
many of these services for the user from the time the device is setup. As these applications are either included in the
main OS or installed before the user completes the device set up, the manufacturer provides a measure of
trustworthiness by documenting the preloaded applications and verifying the preloaded applications do not introduce
security threats.
ETSI
6 ETSI TS 103 732-4 V2.1.1 (2026-09)
The present document identifies key focus areas around the applications preloaded on a consumer mobile device in
typical consumer usage scenarios and identifies security threats to be mitigated in those applications. The identified
threats are mitigated by security objectives, which are in their turn fulfilled by implementing appropriate security
functional requirements.
The present document is defined as a Protection Profile Module (hereafter called PP-Module) following the structure
from the Common Criteria (CC) standards [7], [8], [9], [10], [11] and [12] and therefore can be used for third party CC
security assessments and certification. Notice that the present document has not been evaluated or certified as a formal
PP-Module.
The requirements in the present document take published standards, recommendations and guidance in clause 2 into
consideration.
ETSI
7 ETSI TS 103 732-4 V2.1.1 (2026-09)
1 Scope
The present document defines a PP-Module for Consumer Mobile Device (CMD) which adds additional security
requirements on preloaded applications and the functional capabilities (objectives and security functional requirements)
that are required to mitigate threats from poor programming of those applications.
The present document is intended for CMD manufacturers implementing those security requirements for device
certification and for third parties looking to assess the security functions on CMD such as evaluators.
The Target Of Evaluation (TOE) described by the present document is the set of preloaded applications included on a
CMD.

4.1 TOE Overview
4.1.1 Introduction
This PP-Module introduces additional requirements on applications available on the CMD after the initial CMD setup is
complete. The applications covered by these requirements are divided into preloaded and preinstalled applications. The
requirements for preloaded applications are focused on defining security requirements to ensure they are trustworthy
and maintained properly. The requirements for preinstalled applications are focused on how they are to be installed and
maintained. Special focus is provided for preinstalled applications that are granted system permissions by the TOE
manufacturer.
ETSI
10 ETSI TS 103 732-4 V2.1.1 (2026-09)
The combination of permissions provided to the preloaded and preinstalled applications with system permissions and
how those permissions may be shared across those applications can provide one measure of risk regarding the
applications on the device.
Figure 1: TOE boundary
Figure 1 illustrates the TOE boundary for the PP-Module (as it relates to the entire CMD). Preloaded applications as
defined in ETSI TS 103 732-1 [5] are not changed. Preinstalled applications that are granted system permissions are
included in the TOE.
4.1.2 Preloaded Application Requirements
This PP-Module introduces additional security requirements to the TOE as defined in ETSI TS 103 732-1 [5]
specifically related to preloaded applications in the CMD. These additional requirements provide checks to the design
of the preloaded applications to protect user and TSF data stored in the TOE.
4.1.3 Preinstalled Application Requirements
This PP-Module introduces additional security assurance requirements to the TOE as defined in ETSI TS 103 732-1 [5]
specifically related to some preinstalled applications in the CMD.
The requirements for preinstalled applications are focused on the permissions assigned to such applications. Assigning
system permissions on the CMD can act as an attack vector as a vulnerable application (whether intentionally or not)
may provide additional access to the CMD than would be the case without the elevated permissions.
Additionally, during the initial CMD setup, the preinstalled applications that are downloaded should come from
trustworthy Application Distribution Platforms (ADPs) as specified in ETSI TS 103 732-1 [5].
4.2 Usage and Major Security Features
This is a Protection Profile Module (PP-Module) used to extend a Base-PP for a consumer mobile device to provide
additional security requirements on preloaded applications. As these applications are not explicitly chosen by the user,
the manufacturer can provide additional assurance to the trustworthiness of the CMD by ensuring the applications meet
these requirements.
The major security features are:
• Application Lifecycle: Preinstalled applications downloaded during the initial CMD setup need to be installed
from a trustworthy location.
ETSI
11 ETSI TS 103 732-4 V2.1.1 (2026-09)
• Application Hardening: the preloaded applications follow best practices in development for the platform and
are installed without unnecessary permissions to ensure that user or TOE data is protected.
• Preinstalled Application Permissions: preinstalled applications that are installed on the consumer mobile
device and need to have additional system permissions shall be under the control of the TOE manufacturer.
