Principles of Information Assurance
THE ORGANIZATIONAL/POLICY DOMAIN
Principle One: Organizational Security Policy
The organization will establish an inclusive set of
rational and systematic policies for information assurance. These
will be derived from a commonly accepted model of expert best
practice. They will serve to ensure the protection and management
control of the complete set of identified information and IT assets.
This array of policies will be implemented through a strategic
planning process. It will accurately reflect the long-term
protection needs of each component of the information and IT
resource base. It will ensure full and ongoing protection of all
information assets. It will be continuously audited and enforced by
the business.
Principle Two: Defined and Documented Security
Infrastructure
The organization will design, implement and enforce
a logical and consistent information assurance infrastructure. The
infrastructure will be operated and maintained systematically and
immediately responsive to the protection needs of the information
and IT resource base. The architecture of this framework will embody
procedures tailored to the particular organizational instance. These
procedures will be based on as well as substantiate explicit best
practice control objectives identified during the policy formulation
process. The control objectives that the design process identifies
as appropriate will be audited for conformance.
Principle Three: Education
A proactive program will be established and
maintained to ensure that the human resources of the organization
are fully and continuously aware of security requirements and
procedures relevant to their work. In addition the organization will
develop a comprehensive plan to ensure that staff security
capability will be maintained at acceptable levels, based on defined
criteria. Finally, the organization will develop managerial capacity
both with respect to security strategic planning and also with
respect to supervision and control of the information
resource.
Principle Four: Asset Management
The organization will establish an identification
process and a baseline control scheme for the purpose of specific
asset accounting for security control. The baseline will document
and maintain a specific record of the status of each instance of an
information resource element. Every item in the baseline will be
identified, given a unique identifying label and will be maintained
as an entry within an asset accounting repository. A designated
decision maker will authorize material changes to the form of any
entry in the repository. Upon completion the change must be verified
as correct before being recorded as the current version in the
repository.
Principle Five: Business Continuity
The organization will establish and maintain a
comprehensive action plan and defined practices to insure that
business processes will not be disrupted if the information base is
illegally accessed, or harmed. That includes procedural mechanisms
for the preservation and recovery of information that might have
been lost. Additionally it will involve the implementation and
documentation of a consistent mechanism for the safe backup at a
proscribed point in time and storage of all information assets. It
will further include technical processes for the insurance of
continuous operation of the information processing and storage
function should harm occur.
Principle Six: Regulatory Compliance
The organization will establish comprehensive
control procedures to identify and ensure the compliance of the
information processing function and the information and IT asset
base with all stipulations of contracts regulations and laws. This
will include the definition of an oversight and accountability
scheme to insure that due diligence will be continuously
practiced.
THE MANAGERIAL/ADMINISTRATIVE DOMAIN
Principle Seven: Development Process Security
The organization will establish a defined and repeatable process
that will ensure that a complete and correct set of information
security functional and non-functional requirements is specified and
implemented as integral elements in all software and system
development projects and project work. All development lifecycle
process work will be dictated by, and performed based on, these
requirements.
Principle Eight: Personnel Security
The organization will establish, document and make
public a comprehensive set of formal procedures for assurance of
worker compliance with security policy. This will include the
provision of training sufficient for individual workers to
understand all security policies. This will also involve the
explicit assignment of worker accountability for identified
information and IT assets as well as the definition of procedures to
monitor worker compliance. All workers will be adequately screened
to insure that they comply with the security requirements of their
particular role in the organization. Workers will not be entitled to
retrieve or possess information that they are not been properly
qualified by their designated organizational role to access.
Principle Nine: Physical Security
The security of physical assets and space will be
assured by explicit policies and procedures, which will be
systematically audited for compliance. These will be expressly
designed to ensure that the integrity of all workspaces and physical
resources will be maintained as specified. This will include a
complete set of rational physical asset inventory controls as well
as actions to reliably define and establish a secure perimeter. In
addition the organization will develop, document and make public a
coherent set of control procedures to assure that the physical space
within that boundary is secure.
THE OPERATIONAL/TECHNICAL DOMAIN
Principle Ten: Access Control
The organization will establish a complete set of
procedures to fully monitor and control access, both electronic and
physical, to information and IT resources. Specifically, this will
include the design and implementation of a comprehensive and
rational set of procedures and system utilities to ensure that all
identified information and IT assets are protected from unauthorized
access and/or harm from either internal, or external sources.
Principle Eleven: Operations Security
The organization will insure that staff will only
be involved in work that is appropriate to their role and as defined
by policy and procedure. That includes measures to protect the
organization from harm incurred as a result of the day-to-day course
of doing business.
Principle Twelve: Network
Security
The organization will establish comprehensive
mechanisms to shield processes related to the everyday generation,
manipulation, or transmission of information from unauthorized
access, or harm. That includes the identification and adoption
of electronic and organizational means to ensure that transmissions
of information along public and private networks will fulfill all
availability, integrity and confidentiality requirements. That
includes measures to protect from direct attacks as well as denial
of service and repudiation incidents.
Principle Thirteen: Application and System Software
Security
The organization will establish procedures to
ensure the physical and operational integrity of all application and
system software. This will include mechanisms for timely reporting
and effective response to incidents involving these assets. This
also involves the definition and refinement of software controls to
ensure protection. Utilities will be installed to ensure that all
system and application software will be protected from malicious
code. Additionally, the organization will identify and install
mechanisms to ensure fault tolerance in released versions of all
application and system software.
Principle Fourteen: Risk Assessment and Control
The organization will define explicit and valid
standard operating procedures for the ongoing, business-wide
assessment and control of operational security risks. All current
operations and prospective projects will be systematically evaluated
using this procedure in order to identify any potential threats,
vulnerabilities and weaknesses that might be associated with the
work. Risk assessment will be scheduled and performed on an ongoing
basis as a fundamental element of proper management practice and the
results will be documented and reported to the appropriate
decision-makers for corrective action.
THE COMMUNITY/CONTEXTUAL DOMAIN
Principle Fifteen: Ethics
The organization will delineate, adopt and maintain
a comprehensive code of defined ethical practices with respect to
security. This code will accurately reflect community norms with
respect to ethical behavior. It will underwrite and be directly
referenced to the purpose and goals of the business. The staff will
be explicitly trained with respect to their individual
responsibilities relating to this code and its ramifications. This
code will be rigorously enforced as part of integral organizational
practice. All members of the organization will be held responsible
for violations.
COMMON CRITERIA FOR JUDGING EFFECTIVE
PRACTICE
Principles must meet the following common criteria to be
effectively practiced
Establishment - The organization must document
its commitment to each principle. Criteria for judging this include:
1) The explicit and formally established designation of a manager
responsible for monitoring and controlling ongoing operation, 2) The
placement of the manager in a position of authority sufficient to
enforce decisions, and 3). The continuous maintenance of that
position in the organizational decision making structure
Means - The organization must provide qualified
employees sufficient to ensure that each individual principle will
be effectively carried out. Criteria for judging this include: 1)
The necessary staff and resources to perform the actions embodied in
these principles are identifiably designated and deployed, 2) It is
possible to document, through formal training or recruitment
actions, that staff are competent to perform their assigned roles
and 3) The deployment of staff resources is explicitly demonstrable
and traceable to individual principles.
Oversight - The organization must develop an
objective mechanism to monitor the fulfillment of the purposes of
each principle. Criteria for judging this include: 1) The
development and use of formal measures of performance, 2) Use of
analytic methods to support decision making and 3) The designation
and adherence to formal reporting lines and follow-up
procedures.
Enforcement - The organization must put into
practice and document actions to reliably assure that each principle
is adhered to. Criteria for judging this include: 1) Designation and
empowerment of a person accountable for enforcement, 2) Regularly
scheduled internal audit, or review of the actions embodied in the
principle for compliance and 3) Formally defined procedures for
corrective action.
