This article provides an overview of the newly published information security management system standard ISO/IEC 27001:2013, detailing its requirements for establishing and maintaining an ISMS across various organizations. The standard emphasizes the importance of preserving information confidentiality, integrity, and availability through risk management while also outlining the certification process and associated benefits. The document summarizes the history, structure, and implementation timeline of ISO/IEC 27001:2013 and its relationship with other ISO standards.

1. In this article I will provide an Overview of A new Information Security Management System
Standard ISO/IEC 27001:2013 , The new standard just Published from a few Days Earlier .
ISO/IEC 27001:2013 Provides requirements for Establishing, Implementing, Maintaining
and Continually Improving an Information Security Management System.
The adoption of an information security management system is a strategic decision for
an organization. The establishment and implementation of an organization’s information
security management system is influenced by the organization’s needs and objectives,
The standard covers all types of organizations (e.g. commercial , government agencies,
non-profits), all sizes (from micro-businesses to huge multinationals), and all industries/
segments (e.g. retail, banking, defense, healthcare, education and government).
The Information Security Management System (ISMS) preserves the Confidentiality,
Integrity and Availability of information by applying a Risk Management process and
gives confidence to interested parties that Risks are adequately managed.
• Confidentiality - ensuring that access to information is appropriately authorized
• Integrity - safeguarding the accuracy and completeness of information and processing
methods
• Availability - ensuring that authorized users have access to information when they need it.

Benefits of ISO 27001
ISO/IEC 27001:2013 Implementation, Certification from a certification body demonstrates that the security of
organization information has been addressed, valuable data and information assets properly controlled.
Also there is List of benefits By achieving certification to ISO/IEC 27001:2013 organization will be able to acquire
numerous benefits including:
ISO /IEC 27001:2013 Structure and Content
It’s a new format and wording of Information Security Management System ( ISMS )
This structure is a new formulation of ISO Management System and alignment with “ Annex SL “ that allows an
organization to Made multiple implementation at the same time for related ISO Management Standard.
Now any organization can Implement ISO/IEC 27001:2013 Together with ISO 22301:2012
(Business Continuity Management System) at same time.

The ISO/IEC 27001:2013 Certification Process
There are Three Core Phases
Phase I : Before External Audit
1. Implementation of ISMS
Complete of implementation cycle of Information security management system ( ISMS) Including mandatory
Requirements and optional Controls
2. Conduct Internal Audit and review result by top management
The organization conduct periodic internal audits to ensure the ISMS incorporates adequate controls which operate
effectively and review it by Top Management
3. Selection of a Certification body
Organization select a Certification body “ BSI , DNV, SGS “ to conduct External audit activity and Certified
Organization ISMS Program
Phase II : External Audit
4. Stage 1 Audit
Conducted off or on site to determine if your ISMS system has met the requirements of the standard and is
capable of being audited.
5. Stage 2 Audit
Conduct on site to audit the effectiveness of the ISMS system. Stage 1 and Stage 2 must be completed to become
ISMS certified.
Phase III : Following the audit
6. Confirmation of Registration
Lead Auditor recommend to Certification Manager of Certification Body that Organization are certified.
The Certification Manager will review Organization file to ensure that the recommendation has been made in an
impartial, fair and competent manner.
Upon completion of the above Organization will be officially certified to ISO/IEC 27001:2013 .
7. Continual improvement and Surveillance audits
Conduct Internal Audit Activity by Organization and Certification body auditor will conduct surveillance audit for
organization every 6 months or 12 months for next three years after organization achieve ISO/IEC 27001:2013
Certification

Estimated Time needed for Implementation and Certification ISO/IEC 27001:2013
Based on my Experience
Phase I : Estimated time needed for Implementation ISO/IEC 27001:2013
Estimated Duration needed for Implementation depend on Organization size
“ Employees, Systems and Information “
• Small Organization : 50 - 150 Employee
Estimated time for Implementation of Standard from 6-8 Months
• Medium Organization : 150 – 400 Employee
Estimated time for Implementation of Standard from 10-12 Months
• Large Organization : 400 to 1000+ Employee
Estimated time for Implementation of Standard from 13-16 Months
Phase II : Estimated Time needed for Certification ISO/IEC 27001:2013
Case 1 : if there is one or more Minor Nonconformity and the organization try to Correct them accordingly the
Certificate can be Issued around a Month
Case 2 : if there is one or more Major Nonconformity and the organization try to Correct them accordingly the
Certificate can be Issued around 3-5 Months
Conclusion
ISO/IEC 27001:2013 gives Organization a Perfect Information Security management framework for implementing
and maintaining security.
In this Article, I tried to shed some light on new standard and its Mandatory Requirements, Optional Requirements ,
Structure , Benefits , Certification Process and Estimated time for Implementation and Certification.
