What is Information ?
Information is an asset that, like other important business assets,
is essential to an organization’s business and consequently needs
to be suitably protected. (ISO/ IEC 27002)
Asset: Anything that has value to the organization
Can exist in many forms








data stored on computers
transmitted across networks
printed out
written on a paper sent by fax
stored on disks
held on microfilm
spoken in conversations over the
telephone
..
Information Life Cycle
Information can be :
Created
Stored
Processed
Transmitted
Destroyed ?
Copied
Used– (for proper and improper purposes)
Lost!
Corrupted!
Whatever form the information takes, or means by which it is
shared or stored, it should always be appropriately protected
throughout its life cycle

Information Security ……
Information Security is about protecting Information
through selection of appropriate Security Controls
 protects information from a range of threats
 ensures business continuity
 minimizes financial loss
 maximizes return on
investments and business
opportunities

Objectives of Information
Security
Preservation of
Confidentiality :
Ensuring that information is available to only those
authorised to have access.
Integrity
:
Safeguarding the accuracy and completeness of
information & processing methods.
Availability
:
Ensuring that information and vital services are
available to authorized users when required.

Information Security Model
ISMS Auditor / Lead Auditor Training Course Version 4.4
7
Why ISMS ?
 Information security that can be achieved through technical
means is limited
 Security also depends on people, policies, processes and
procedures
 Resources are not unlimited
 It is not a once off exercise, but an ongoing activity
All these can be addressed effectively and
efficiently only by establishing a proper
Information Security Management System(ISMS)
ISMS Auditor / Lead Auditor Training Course Version 4.4

Information Security Management
System (ISMS)
 ISMS is that part of overall management system based on a
business risk approach to
•
•
•
•
•
•
•
Establish
Implement
Operate

Review
Maintain &
Improve
Information security
 ISMS is a management assurance mechanism for security of
information asset concerning its
• availability
• integrity and
• Confidentiality

ISMS Standards
 ISO/ IEC 27001 : 2005
• A specification (specifies requirements for implementing,
operating, monitoring, reviewing, maintaining & improving a
documented ISMS)
• Specifies the requirements of implementing of Security
control, customised to the needs of individual organisation or
part thereof.
• Used as a basis for certification
 ISO/IEC 27002 : 2005 (Originally ISO/IEC 17799:2005)
•
•
•
•
A code of practice for Information Security management
Provides best practice guidance
Use as required within your business
Not for certification
Both ISO 27001 and ISO 27002 security control clauses
are fully harmonized

Basic Requirements for
Certification - 1
Evidence of creation of ISMS through system
requirements:

 Scope Statement
 Risk Assessment
 Statement of Applicability
 The Management System
ISMS Auditor / Lead Auditor Training Course Version 4.4
31
Basic Requirements for
Certification - 2
Evidence of operation of Management controls:
 Management Review
 Various forms of system review
 Document management
 Records Management
 Existence of essential controls
 Implementation & effectiveness of controls selected
as applicable
ISMS Auditor / Lead Auditor Training Course Version 4.4
32
Maintenance of Certification
 Surveillance Audits
• The purpose of surveillance is
o to verify that the approved ISMS continues to be implemented,
o to consider the implications of changes to that system initiated as a
result of changes in the client organization’s operation and
o to confirm continued compliance with certification requirements.
• Surveillance programs should normally cover
o the system maintenance elements which are internal ISMS audit,
management review and preventive and corrective action;
o changes to the documented system;
o areas subject to change;
o selected elements of ISO/IEC 27001;
o other selected areas as appropriate.
ISMS Auditor / Lead Auditor Training Course Version 4.4
33
ISMS Certification V/s Legal
Compliance
 ISMS Certification is a voluntary Certification and is not a substitute
for compliance to legal requirements. Compliance with ISO 27001
does not in itself confer immunity from legal obligations.
 The maintenance and evaluation of legal and regulatory compliance
is the responsibility of the client organization.
 The certification body shall restrict itself to checks and samples in
order to establish confidence that the ISMS functions in this regard.
 The certification body shall verify that the client organization has a
management system to achieve legal and regulatory compliance
applicable to the information security risks and impacts.

Benefits of ISO27001
Certification
An internationally recognized structured
methodology
A single reference point for identifying a range
of controls needed for most situations where
information systems are used
A defined process to evaluate, implement,
maintain and manage information security
The standard provides a yardstick against which security can
be judged
A set of tailored policy, standards, procedures
and guidelines
Facilitation of Trade in trusted environment
