- Security Program
- Organization-wide
security practice in a
holistic manner
- logical, administrative and physical
protection mechanisms, procedures,
business processes and people, that all
work together to provide a protection
level for an environment
- based on a flexible and
well defined framework
- framework defines the general requirement and
structure of the security program where organizations
are free to plug in different types of technologies,
methods, and procedures to accomplish the necessary
protection level

- British Standard 7799 (BS7799)
- 1995. UK govt department of trade and industry. Outlines how an information security
management system (ISMS) (aka a security program) should be built and maintained.
Provides guidance to organizations on how to design, implement and maintain policies,
processes and technologies to manage risk to sensitive information assets.

- ISO/IEC 27000
- ISO and IEC built on top of BS7799 to launch new global standard. Serves as industry best
practices for management of security controls in a holistic manner within orgs around the
world. It's common for orgs to seeks ISO/IEC 27001 certification by an accredited third party.

- Program specifies the pieces and
parts that need to be put in place to
provide a holistic security for the
organization overall and how to
properly take care of those pieces
and parts
- Architecture illustrates how these
components are to be integrated into the
different layers of the current business
environment
- e.g. security program could dictate the data that
needs to be put in place. The architecture can
show how this happens at the infrastructure,
application, component and business level.

- Enterprise Security Architecture
- A subset of an enterprise architecture.
Defines the infosec security strategy that
consists of layers of solutions, processes and
procedures and the way they are linked
across an enterprise strategically, tactically,
and operationally.
- Describes the structure and behavior of all components that
make up a holistic information security management
system. Ensures that security efforts align with business
practices in a standardized and cost effective manner.

- Process enhancement
- When an organization is developing its security enterprise
components, those components must be integrated into the
business processes to be effective. This can allow for process
management to be refined and calibrated.

be implemented to better enable them.

- Security controls needs to be used effectively and efficiently
by proper process. The security controls can be considered
the “things,” and processes are how we use these things.
