The Protection Profile mentioned above was evaluated at an accredited and licenced/approved evaluation facility using
the Common Methodology for IT Security Evaluation, Version 2.4 revision 256 including draft interpretation #1 - #17 for
conformance to the Common Criteria for IT Security Evaluation, Version 2.4, revision 256.
This certificate applies only to the specific version and release of the Protection Profile and in conjunction with the
complete Certification Report.
The evaluation has been conducted in accordance with the provisions of the certification scheme of the Federal Office for
Information Security. The conclusions of the evaluation facility in the evaluation technical report are consistent with the
evidence adduced.
This certificate is not an endorsement of the Protection Profile by the Federal Office for Information Security or any other
organisation that recognises or gives effect to this certificate, and no warranty of the Protection Profile by the Federal
Office for Information Security or any other organisation that recognises or gives effect to this certificate, is either
expressed or implied.

Preliminary Remarks
Under the BSIG1
Act, the Federal Office for Information Security (BSI) has the
task of issuing certificates for information technology products as well as for
Protection Profiles (PP).
A PP defines an implementation-independent set of IT security requirements for
a category of TOEs which are intended to meet common consumer needs for IT
security. The development and certification of a PP or the reference to an
existent one gives consumers the possibility to express their IT security needs
without referring to a special product. Product or system certifications can be
based on Protection Profiles. For products which have been certified based on
a Protection Profile an individual certificate will be issued.
Certification of the Protection Profile is carried out on the instigation of the BSI.
A part of the procedure is the technical examination (evaluation) of the
Protection Profile according to Common Criteria [1].
According to the decree issued by the Bundesministerium des Innern (Federal
Ministry of the Interior) on February 22nd
, 2005 the BSI is authorised to issue
certificates on the basis of CC version 2.4.
The evaluation is carried out by an evaluation facility recognised by the BSI or
by the BSI itself.
The result of the certification procedure is the present Certification Report. This
report contains among others the certificate (summarised assessment) and the
detailed Certification Results.

2 Recognition Agreements
In order to avoid multiple certification of the same Protection Profile in different
countries a mutual recognition of Protection Profile certificates under certain
conditions was agreed.
An arrangement (Common Criteria Arrangement) on the mutual recognition of
certificates based on the CC evaluation assurance levels up to and including
EAL 4 was signed in May 2000. It includes also the recognition of Protection
Profiles based on the CC. The arrangement was signed by the national bodies
of Australia, Canada, Finland France, Germany, Greece, Italy, The Netherlands,
New Zealand, Norway, Spain, United Kingdom and the United States. Israel
joined the arrangement in November 2000, Sweden in February 2002, Austria
in November 2002, Hungary and Turkey in September 2003, Japan in
November 2003, the Czech Republic in September 2004, the Republic of
Singapore in March 2005 and India in April 2005.

3 Performance of Evaluation and Certification
The certification body monitors each individual evaluation to ensure a uniform
procedure, a uniform interpretation of the criteria and uniform ratings.
The Low Assurance Protection Profile for a ‘Voice over IP Infrastructure’,
Version 1.1 has undergone the certification procedure at the BSI.
The evaluation of the Low Assurance Protection Profile for a ‘Voice over IP
Infrastructure’, Version 1.1 was conducted by the ‘SRC Security Research and
Consulting GmbH’. The evaluation facility of ‘SRC Security Research and
Consulting GmbH’ is an evaluation facility (ITSEF)5
recognised by BSI.
Author is TNO-ITSEF BV.
The certification was concluded with
· the comparability check and
· the preparation of this Certification Report.
This work was completed by the BSI on May 12th
; 2005.

1 PP Overview
This Low Assurance Protection Profile for a ‘Voice over IP Infrastructure’,
Version 1.1 is established by TNO-ITSEF BV as basis for the development of
STs for a VoIP (Voice over IP) infrastructure, as it is used in a typical office
environment. The goal of this VoIP infrastructure is to provide telephone and
services over an already available IP network thereby obviating the need for a
separate telephone infrastructure and allowing the integration between
telephony services and other services (e.g. agenda services).
IP telephony enables calls to be made between IP telephone devices and
between an IP telephone device and a traditional telephone on a PSTN
(Publicly Switched Telephone Network).
2 Security Functional Requirements
This section contains the functional requirements that must be satisfied by a
TOE claiming compliance to the Low Assurance Protection Profile for a ‘Voice
over IP Infrastructure’, Version 1.1.
All functional requirements are drawn from Common Criteria Part 2.
SFRs Component-Name
FAU_GEN.1 Security audit data generation
FDP_ACC.1 Subset access control
FDP_ACF.1 Security attribute based access control
FIA_UID.2 User identification before any action
FIA_UAU.1 Timing of authentication
FIA_UAU.2 User authentication before any action
FMT_MSA.1 Management of security attributes
FMT_MTD.1 Management of TSF data
FMT_SMR.1 Security roles
FPT_SEP.1 TSF domain separation
3 Assurance Package
The security assurance requirements are based entirely on the assurance
components defined in Part 3 of the Common Criteria. The assurance require-
ments are assurance level EAL1 (Evaluation Assurance Level 1).
4 Strength of Functions
The strength of function-examination is no more part of the CC in version 2.4.
