What is Information? – an asset that has value to an organization – exist in several forms: • messages written on paper, stored in tapes, transmitted in electronic forms, etc – needs to be suitably protected against wide range of threats to ensure: • business continuity • minimize business loss • maximize ROI and business opportunities Information Security is the preservation of: – Confidentiality • ensuring that information is accessible only to those authorized to have access – Integrity • safeguarding the accuracy and completeness of information and processing methods – Availability • ensuring that authorized users have access to information and associated assets when required Information Security Management Systems (ISMS) – provides a systematic approach to secure sensitive information – encompasses employees, processes and information systems – includes all the good information security practices What is ISO 27001 standard? – the formal standard against which organizations may seek independent certification of their Information –



Security Management Systems (ISMS)

to provide a common base for: • developing organizational security standards and effective security management practice • to provide confidence in inter-organizational dealings ISO 27001 addresses management system in the area of information security – holistic approach by risk assessment & management – incorporate best industry practices – 133 controls to be selected for implementation

Plan-Do-Check-Act (PDCA) model to achieve continual improvement

ISO 27001 Certification Road map (2 phases) 1. Gap analysis - Getting the ISO 27001 standard - List of identified gaps - Cost and schedule estimation

Phase 1:

2. Setting up ISMS framework -Scope, policy and ISMS framework - Prepare Statement of Applicability (SOA) and produce Risk Assessment (RA) results

Pre-Certification Phase

3. Implementation - Training and communication - Implementation of controls 4.Documentation -Control policy, procedures, work instructions, etc.

5. Application for ISO 27001 certification Phase 2: Certification

6. Document (Manual) assessment (Stage 1)

Phase 7. Preliminary assessment (Stage 1) - Records demonstrating ISMS implementation

8. Certification assessment (Stage 2) -Assessment report and Corrective Action (CA) 9. Awarding of certificate

Setting up ISMS framework 1. Define the scope of the ISMS

Step 1

2. Define the ISMS policy

Management Commitment Cross-functional forum / committee Understanding Stakeholders’ business requirements in relation to Information Security Effective Risk Management Process Training & Awareness Proactive & Continual Improvement • Internal audit & management review • Identify and act on security weaknesses • Learn from incidents and establish relevant Prevention Action

ISO 27002: ISO/IEC 17799:2005 (from 2007) • • •

11 sections specify 39 control objectives to protect information assets Provides 133 best practice controls that can be adopted based on a risk assessment process – but leaves an organisation free to select controls not listed in the standard – giving great flexibility in implementation (but challenging for certification bodies!) New recommendations cover : - security of external service delivery & provisioning of outsourcing - patch management and other current issues - security prior to, during and at termination of employment - guidance on risk management, and a section on incident management - mobile, remote & distributed communications & information processing

ISO 27003 : ISMS Implementation Guidelines •



A new project to cover:- overview - management responsibilities - governance & regulatory compliance - personal security & human resources - asset management - availability/continuity of business processes - handling information incidents - access control - risk management case studies Available in 2009

ISO 27004: Measurement Programme Objectives • • •

Covers information security system management measurement and metrics Helps to measure the effectiveness of information security Management system implementations.

The objectives are to: • Evaluate the effectiveness of security controls & control objectives; • Evaluate the effectiveness of the ISMS inc. continual improvement; • Provide security indicators to assist management review • Facilitate improvement of information security • Provide input for security audits; • Communicate the effectiveness of ISM to the organization; • Serve as an input into the risk management process • Provide output for internal comparison & benchmarking of effectiveness This development is aimed at addressing how to measure the effectiveness of ISMS implementations (processes and controls) • Performance targets • What to measure • How to measure การประเมินมีหลายวิธีควรตกลงกันกอนวาจะใชวิธีใด • Qualitative Æ SO27001 ทํา Gap Analysis , Benchmarking และทํา Scoring

ISO 27006: Guidelines on ISMS Accreditation • International ISO2700 community realised that the guidance to certification/registration bodies – currently EA7/03 was now outdated • There is a need for increased rigour & evidence from certifying bodies that the organisations going for certification are ‘fit for purpose’ i.e. that a robust ISMS framework is not only well established (meeting business needs) but it is also well communicated and is working in practice • These guidelines will be operation from January 2007 (launched at ‘ISO27000 Business goes Global’ in London)
