Introduction
This Technical Specification provides an Information Security Management Process Assessment Model
(PAM) for use in performing a conformant assessment of process capability in accordance with the
requirements of ISO/IEC 33002. It is structured in accordance with the requirements of ISO/IEC 33004 to
reflect processes that enable implementation of ISO/IEC 27001. The scale for assessing the extent of
achievement of process capability is based on ISO/IEC 33020.
An integral part of conducting an assessment is to use a PAM that is constructed for that purpose. A PAM is
related to a Process Reference Model (PRM) and is conformant with ISO/IEC 33004. ISO/IEC 33002 identifies
the minimum requirements for performing an assessment in order to ensure consistency and repeatability of
the ratings. ISO/IEC 33002 addresses the assessment of process and the application of process assessment
for improvement and capability determination. Results of conformant process assessments can be compared
when the scopes of the assessments are considered to be similar. The requirements for process assessment
defined in ISO/IEC 33002 form a structure which:
a) facilitates self-assessment;
b) provides a basis for use in process improvement and capability determination;
c) takes into account the context in which the assessed process is implemented;
d) produces a process rating;
e) addresses the ability of the process to achieve its purpose;
f) is applicable across all application domains and sizes of organization;
g) can provide an objective benchmark between organizations.
The PRM defined in ISO/IEC TS 33052 has been used as the basis for the PAM in ISO/IEC TS 33072; the
process measurement framework for process capability defined in ISO/IEC 33020 is the basis for the
capability measurement scale. The relationship between ISO/IEC 24774, ISO/IEC 27001, ISO/IEC 3002,
ISO/IEC 33004, ISO/IEC 33020, ISO/IEC TS 33052 and ISO/IEC TS 33072 is shown in Figure 1.

Any organisation can use processes with additional elements in order to suit it to the environment and
circumstances. This PAM contains a set of indicators to be considered when interpreting the intent of its PRM.
It provides greater detail to indicate process performance and capability. The indicators can also be used
when implementing a process improvement program or to help evaluate and select an assessment model,
method, methodology or tools.
This PAM embodies the core characteristics that could be expected of any PAM consistent with
ISO/IEC 33004. Nevertheless any other PAMs meeting the requirements of ISO/IEC 33004 can be used in a
conformant assessment.
ISO/IEC 33072 has a similar structure to ISO/IEC 15504-5 and ISO/IEC 15504-6. It can be used in
conjunction with these process assessment models to support joint assessment of information security
processes and system/software life cycle processes.
Within this Technical Specification:
 Clause 4 provides a detailed description of the structure and key components of a PAM, which
includes two dimensions: a process dimension and a capability dimension. Assessment indicators
are introduced in this clause;
 Clause 5 addresses the process dimension. It uses process definitions from ISO/IEC TS 33052 to
designate the PRM. The processes of the PRM are described in the PAM in terms of purpose and
outcomes. The PAM expands the PRM process definitions by including a set of process performance
indicators called base practices for each process. The PAM also defines a second set of indicators of
process performance by associating inputs and outputs with each process. Clause 5 is also linked
directly to Annex B, which defines the inputs/outputs characteristics;
 Clause 6 addresses the capability dimension. It duplicates the definitions of the capability levels and
process attributes from ISO/IEC 33020, and expands each of the nine attributes through the inclusion
of a set of generic practices. These generic practices belong to a set of indicators of process
capability, in association with generic resource indicators, and generic inputs/outputs indicators.
Annex B is also linked directly to Clause 6 as it defines the inputs/outputs characteristics;

 Annex A provides a statement of conformance of the PAM to the requirements defined in
ISO/IEC 33004;
 Annex B provides selected characteristics for typical inputs/outputs to assist the assessor in
evaluating the capability level of processes;
 Annex C contains three tables. Table C.1 identifies the base practices linked to requirements;
Table C.2 identifies the requirements linked to base practices; and lastly, Table C.3 identifies the
base practices not linked to requirements.

TECHNICAL SPECIFICATION ISO/IEC TS 33072:2016(E)
Information technology — Process assessment — Process capability
assessment model for information security management
1 Scope
This Technical Specification:
 defines a process assessment model (PAM) that meets the requirements of ISO/IEC 33004 and that
supports the performance of an assessment of process capability by providing indicators for guidance on
the interpretation of the process purposes and outcomes as defined in ISO/IEC TS 33052 and the
process attributes as defined in ISO/IEC 33020;
 provides guidance, by example, on the definition, selection and use of assessment indicators.
A PAM comprises a set of indicators of process performance and process capability. The indicators are used
as a basis for collecting the objective evidence that enables an assessor to assign ratings. The set of
indicators included in this Technical Specification is not intended to be an all-inclusive set nor is it intended to
be applicable in its entirety.
The PAM in this Technical Specification is directed at assessment sponsors and competent assessors who
wish to select a model, and associated documented process method, for assessment (for either capability
determination or process improvement). Additionally it may be of use to developers of assessment models in
the construction of their own model, by providing examples of good information security management
practices. It can be used by:
a) service providers to assess and improve an Information Security Management System (ISMS);
b) service providers to demonstrate their capability for the design, development, transition and delivery
of services that fulfil information security management requirements.
Any PAM meeting the requirements defined in ISO/IEC 33004 concerning models for process assessment
can be used for assessment. Different models and methods might be needed to address differing business
needs. The assessment model in this Technical Specification meets all the requirements expressed in
ISO/IEC 33004.
NOTE Copyright release for the PAM: Users of this Technical Specification may reproduce subclauses 5.2 to 5.27,
6.2, B.2 and B.3 as part of any tool or other material to support the performance of process assessments so that it can be
used for its intended purpose.

4 Overview of the Process Assessment Model
4.1 Introduction to Overview
ISO/IEC 33072 provides a PAM that includes examples of assessment indicators.
The PRM defined in ISO/IEC TS 33052, associated with the process attributes defined in ISO/IEC 33020,
establish a PAM used as a common basis for performing assessments of information security management
system process capability, allowing for the reporting of results using a common rating scale.
This PAM is a two-dimensional model of the process quality characteristic of process capability. In one
dimension, the process dimension, the processes are defined. In the other dimension, the capability
dimension, a set of process attributes grouped into capability levels is defined. The process attributes provide
the measurable characteristics of the process quality characteristic of process capability.

Figure 2 — Relationship between the Process Assessment Model and its inputs

Figure 2 shows the relationship between the general structure of the PAM, ISO/IEC 33020 and ISO/IEC TS
33052.
A PRM conformant with the requirements defined in ISO/IEC 33004 and a capability dimension defined in
ISO/IEC 33020 cannot be used alone as the basis for conducting reliable and consistent assessments of
process capability since the level of detail provided is not sufficient. The descriptions of process purpose and
outcomes in a PRM, and the process attribute definitions in ISO/IEC 33020, need to be supported with a
comprehensive set of indicators of process performance and process capability that are used for assessment
performance.
The PAM defined in ISO/IEC 33072 is conformant with the ISO/IEC 33004 requirements for a PAM, and can
be used as the basis for conducting an assessment of information security management process capability.

---------------------- Page: 10 ----------------------
ISO/IEC TS 33072:2016(E)
In order to meet the PAM requirements of ISO/IEC 33004, a documented process supporting other
requirements of ISO/IEC 33002 is also required. This need may be met, for example, by the adoption of a
supporting method for conducting assessments.
4.2 Structure of the Process Assessment Model
This clause describes the detailed structure of the PAM and its key components.
This PAM expands upon the PRM by including a defined set of assessment indicators. Assessment indicators
comprise indicators of process performance and process capability and are defined to support an assessor’s
judgment of the performance and capability of an implemented process.
Clause 5, together with its associated Annex B, describes the components of the process dimension, and
clause 6 describes the components of the capability dimension. Annex A provides a statement of
conformance of the PAM to the requirements defined in ISO/IEC 33004.
ISO/IEC 33004 requires that processes included in a PRM satisfy the following:
" The fundamental elements of a process reference model are the descriptions of the processes within the
scope of the model.
The process descriptions in the process reference model incorporate a statement of the purpose of the
process which describes at a high level the overall objectives of performing the process, together with the set
of outcomes which demonstrate successful achievement of the process purpose.
A process description shall meet the following requirements:
a) a process shall be described in terms of its purpose and process outcomes;
b) the set of process outcomes shall be necessary and sufficient to achieve the purpose of the process;
c) process descriptions shall not contain or imply aspects of the process quality characteristic beyond the
basic level of any relevant process measurement framework conformant with ISO/IEC 33003."
As processes are derived directly from ISO/IEC TS 33052, these requirements are satisfied.

Figure 3 shows the processes from ISO/IEC TS 33052, which are included in the process dimension of the
PAM for information security management.

Figure 3 — Processes in the Process Reference Model
4.2.2 Process dimension
The process dimension of the PAM includes all processes from the PRM contained in ISO/IEC TS 33052 and
shown in Figure 3. Each process in the PAM is described in terms of a purpose statement. These statements
contain the unique functional objectives of the process when performed in a particular environment. A list of
specific outcomes is associated with each of the process purpose statements, as a list of expected positive
results of the performance of the processes.
Satisfying the purpose statements of a process represents the first step in building a level 1 process capability
where the expected outcomes are observable. The processes are described in Clause 5.
4.2.3 Capability dimension
For the capability dimension, the process capability levels and process attributes are identical to those defined
in ISO/IEC 33020.
Evolving process capability is expressed in the PAM in terms of process attributes grouped into capability
levels. Process attributes are features of a process that can be evaluated on a scale of achievement,
providing a measure of the capability of the process. They are applicable to all processes. Each process
attribute describes a facet of the overall capability of managing and improving the effectiveness of a proc

ISO/IEC TS 33072:2016(E)
Introduction
This Technical Specification provides an Information Security Management Process Assessment Model
(PAM) for use in performing a conformant assessment of process capability in accordance with the
requirements of ISO/IEC 33002. It is structured in accordance with the requirements of ISO/IEC 33004 to
reflect processes that enable implementation of ISO/IEC 27001. The scale for assessing the extent of
achievement of process capability is based on ISO/IEC 33020.
An integral part of conducting an assessment is to use a PAM that is constructed for that purpose. A PAM is
related to a Process Reference Model (PRM) and is conformant with ISO/IEC 33004. ISO/IEC 33002 identifies
the minimum requirements for performing an assessment in order to ensure consistency and repeatability of
the ratings. ISO/IEC 33002 addresses the assessment of process and the application of process assessment
for improvement and capability determination. Results of conformant process assessments can be compared
when the scopes of the assessments are considered to be similar. The requirements for process assessment
defined in ISO/IEC 33002 form a structure which:
a) facilitates self-assessment;
b) provides a basis for use in process improvement and capability determination;
c) takes into account the context in which the assessed process is implemented;
d) produces a process rating;
e) addresses the ability of the process to achieve its purpose;
f) is applicable across all application domains and sizes of organization;
g) can provide an objective benchmark between organizations.
The PRM defined in ISO/IEC TS 33052 has been used as the basis for the PAM in ISO/IEC TS 33072; the
process measurement framework for process capability defined in ISO/IEC 33020 is the basis for the
capability measurement scale. The relationship between ISO/IEC 24774, ISO/IEC 27001, ISO/IEC 3002,
ISO/IEC 33004, ISO/IEC 33020, ISO/IEC TS 33052 and ISO/IEC TS 33072 is shown in Figure 1.

Any organisation can use processes with additional elements in order to suit it to the environment and
circumstances. This PAM contains a set of indicators to be considered when interpreting the intent of its PRM.
It provides greater detail to indicate process performance and capability. The indicators can also be used
when implementing a process improvement program or to help evaluate and select an assessment model,
method, methodology or tools.
This PAM embodies the core characteristics that could be expected of any PAM consistent with
ISO/IEC 33004. Nevertheless any other PAMs meeting the requirements of ISO/IEC 33004 can be used in a
conformant assessment.
ISO/IEC 33072 has a similar structure to ISO/IEC 15504-5 and ISO/IEC 15504-6. It can be used in
conjunction with these process assessment models to support joint assessment of information security
processes and system/software life cycle processes.
Within this Technical Specification:
 Clause 4 provides a detailed description of the structure and key components of a PAM, which
includes two dimensions: a process dimension and a capability dimension. Assessment indicators
are introduced in this clause;
 Clause 5 addresses the process dimension. It uses process definitions from ISO/IEC TS 33052 to
designate the PRM. The processes of the PRM are described in the PAM in terms of purpose and
outcomes. The PAM expands the PRM process definitions by including a set of process performance
indicators called base practices for each process. The PAM also defines a second set of indicators of
process performance by associating inputs and outputs with each process. Clause 5 is also linked
directly to Annex B, which defines the inputs/outputs characteristics;
 Clause 6 addresses the capability dimension. It duplicates the definitions of the capability levels and
process attributes from ISO/IEC 33020, and expands each of the nine attributes through the inclusion
of a set of generic practices. These generic practices belong to a set of indicators of process
capability, in association with generic resource indicators, and generic inputs/outputs indicators.
Annex B is also linked directly to Clause 6 as it defines the inputs/outputs characteristics;

TECHNICAL SPECIFICATION ISO/IEC TS 33072:2016(E)
Information technology — Process assessment — Process capability
assessment model for information security management
1 Scope
This Technical Specification:
 defines a process assessment model (PAM) that meets the requirements of ISO/IEC 33004 and
that supports the performance of an assessment of process capability by providing indicators for guidance on
the interpretation of the process purposes and outcomes as defined in ISO/IEC TS 33052 and the
process attributes as defined in ISO/IEC 33020;
 provides guidance, by example, on the definition, selection and use of assessment indicators.
A PAM comprises a set of indicators of process performance and process capability. The indicators are used
as a basis for collecting the objective evidence that enables an assessor to assign ratings. The set of
indicators included in this Technical Specification is not intended to be an all-inclusive set nor is it intended to
be applicable in its entirety.
The PAM in this Technical Specification is directed at assessment sponsors and competent assessors who
wish to select a model, and associated documented process method, for assessment (for either capability
determination or process improvement). Additionally it may be of use to developers of assessment models in
the construction of their own model, by providing examples of good information security management
practices. It can be used by:
a) service providers to assess and improve an Information Security Management System (ISMS);
b) service providers to demonstrate their capability for the design, development, transition and delivery
of services that fulfil information security management requirements.
Any PAM meeting the requirements defined in ISO/IEC 33004 concerning models for process assessment
cab be used for assessment. Different models and methods might be needed to address differing business
needs. The assessment model in this Technical Specification meets all the requirements expressed in
ISO/IEC 33004.

For the purposes of this document, the terms and definitions given in ISO/IEC 33001 and ISO/IEC 27000
apply.
4 Overview of the Process Assessment Model
4.1 Introduction to Overview
ISO/IEC 33072 provides a PAM that includes examples of assessment indicators.
The PRM defined in ISO/IEC TS 33052, associated with the process attributes defined in ISO/IEC 33020,
establish a PAM used as a common basis for performing assessments of information security management
system process capability, allowing for the reporting of results using a common rating scale.
This PAM is a two-dimensional model of the process quality characteristic of process capability. In one
dimension, the process dimension, the processes are defined. In the other dimension, the capability
dimension, a set of process attributes grouped into capability levels is defined. The process attributes provide
the measurable characteristics of the process quality characteristic of process capability.

Figure 2 — Relationship between the Process Assessment Model and its inputs

Figure 2 shows the relationship between the general structure of the PAM, ISO/IEC 33020 and ISO/IEC TS
33052.
A PRM conformant with the requirements defined in ISO/IEC 33004 and a capability dimension defined in
ISO/IEC 33020 cannot be used alone as the basis for conducting reliable and consistent assessments of
process capability since the level of detail provided is not sufficient. The descriptions of process purpose and
outcomes in a PRM, and the process attribute definitions in ISO/IEC 33020, need to be supported with a

ISO/IEC TS 33072:2016(E)
comprehensive set of indicators of process performance and process capability that are used for assessment
performance.
The PAM defined in ISO/IEC 33072 is conformant with the ISO/IEC 33004 requirements for a PAM, and can
be used as the basis for conducting an assessment of information security management process capability.
In order to meet the PAM requirements of ISO/IEC 33004, a documented process supporting other
requirements of ISO/IEC 33002 is also required. This need may be met, for example, by the adoption of a
supporting method for conducting assessments.
4.2 Structure of the Process Assessment Model
This clause describes the detailed structure of the PAM and its key components.
This PAM expands upon the PRM by including a defined set of assessment indicators. Assessment indicators
comprise indicators of process performance and process capability and are defined to support an assessor’s
judgment of the performance and capability of an implemented process.
Clause 5, together with its associated Annex B, describes the components of the process dimension, and
clause 6 describes the components of the capability dimension. Annex A provides a statement of
conformance of the PAM to the requirements defined in ISO/IEC 33004.
ISO/IEC 33004 requires that processes included in a PRM satisfy the following:
" The fundamental elements of a process reference model are the descriptions of the processes within the
scope of the model.
The process descriptions in the process reference model incorporate a statement of the purpose of the
process which describes at a high level the overall objectives of performing the process, together with the set
of outcomes which demonstrate successful achievement of the process purpose.
A process description shall meet the following requirements:
a) a process shall be described in terms of its purpose and process outcomes;
b) the set of process outcomes shall be necessary and sufficient to achieve the purpose of the process;
c) process descriptions shall not contain or imply aspects of the process quality characteristic beyond the
basic level of any relevant process measurement framework conformant with ISO/IEC 33003."
As processes are derived directly from ISO/IEC TS 33052, these requirements are satisfied.

Figure 3 shows the processes from ISO/IEC TS 33052, which are included in the process dimension of the
PAM for information security management.

Figure 3 — Processes in the Process Reference Model
4.2.2 Process dimension
The process dimension of the PAM includes all processes from the PRM contained in ISO/IEC TS 33052 and
shown in Figure 3. Each process in the PAM is described in terms of a purpose statement. These statements
contain the unique functional objectives of the process when performed in a particular environment. A list of
specific outcomes is associated with each of the process purpose statements, as a list of expected positive
results of the performance of the processes.
Satisfying the purpose statements of a process represents the first step in building a level 1 process capability
where the expected outcomes are observable. The processes are described in Clause 5.
4.2.3 Capability dimension
For the capability dimension, the process capability levels and process attributes are identical to those defined
in ISO/IEC 33020.
Evolving process capability is expressed in the PAM in terms of process attributes grouped into capability
levels. Process attributes are features of a process that can be evaluated on a scale of achievement,
providing a measure of the capability of the process. They are applicable to all processes. Each process
attribute describes a facet of the overall capability of managing and improving the effectiveness of a process
in achieving its purpose and contributing to the business goals of the organization.
A capability level is a set of process attribute(s) that work together to provide a major enhancement in the
capability to perform a process. The levels constitute a rational way of progressing
