I have kind of developed a 13 step program to an ISMS….

ISMS - An information security management system

 

 

13 Steps Program:

 

 

1. Purchase a copy of the ISO/IEC standards

2. Obtain Management Support

3. Determine the Scope of the ISMS

4. Identify Applicable Legislation

5. Define a Method of Risk Assessment

6. Create an Inventory of Information Assets to Protect

7. Identify Risks

8. Assess the Risks

9. Identify Applicable Objectives and Controls

10. Set up Policy and Procedures to Control Risks

11. Allocate Resources and train the Staff

12. Monitor the Implementation of the ISMS

13. Prepare for Certification Audit

 

 

1 Purchase a copy of the ISO/IEC standards

 

 

The code of practice standard: ISO/IEC 27002 (ISO/IEC 17799)

 

 

This standard can be used as a starting point for developing an ISMS. It provides guidance for planning and implementing a program to protect information assets. It also provides a list of controls (safeguards) that you can consider implementing as part of your ISMS.

 

 

The management system standard: ISO/IEC 27001

 

 

This standard is the specification for an ISMS. It explains how to apply ISO/IEC 27002 (ISO/IEC 17799). It provides the standard against which certification is performed, including a list of required documents. An organization that seeks certification of its ISMS is examined against this standard.

2 Obtain management support

 

 

• An information security policy;

• Information security objectives and plans;

• Roles and responsibilities for information security;

• Announcement or communication about the ISMS

 

 

Further on:

 

Management will participate in the ISMS Plan-Do-Check-Act

 

 

• Determining the acceptable level of risk.

• Conducting management reviews of the ISMS at planned intervals

• Ensuring that personnel affected by the ISMS are provided with training

 

3 Determine the scope of the ISMS

 

 

Lists of the areas, locations, assets, and technologies of the organization that will be controlled by the ISMS.

 

 

4 Identify applicable legislation

 

 

Up-to-date regulatory or legislative standards that might be applicable to your organization.

 

5 Define a method of risk assessment

 

 

• Loss of Integrity.

• Loss of Availability.

• Loss of Confidentiality

• Quantitative Risk Assessment

• Qualitative Risk Assessment

 

 

6 Create an inventory of information assets to protect

 

 

When you have completed this step, you should have a list of the information assets to be protected and an

owner for each of those assets. You might also want to identify where the information is located and how critical or difficult it would be to replace.

 

7 Identify risks

 

 

• Step 1 System Characterization

• Step 2 Threat Identification

• Step 3 Vulnerability Identification

• Step 4 Control Analysis

• Step 5 Likelihood Determination

• Step 6 Impact Analysis

• Step 7 Risk Determination

• Step 8 Control Recommendations

• Step 9 Results Documentation

 

8 Assess the risks

 

 

Risk = Likelihood x Impact

 

 

9 Identify applicable objectives and controls

 

 

Annex A of ISO/IEC 27001. This appendix summarizes controls that you might want to choose from.

ISO/IEC 27002 (ISO/IEC 17799), which provides greater detail about the controls summarized in ISO/IEC 27001.

 

10 Set up policy and procedures to control risks

 

 

Most probably:

 

• Security Manual

• Security Policy

• Risk Assessment Methodology

• Risk Assessment Report, Asset List, and Treatment Plan

• Statement of Applicability

• Roles and Responsibilities document

• Procedure 1: Workplace Security

• Procedure 2: Document and Record Control

• Procedure 3: Training

• Procedure 4: Server Backups

• Procedure 5: Audit Procedure

• Records:

• Audit Schedule

• Employee Training Records

• Employee Review/Evaluation Records

• Issues/Non-Conformances

• Server Maintenance Records

• …..Management Review Records

 

11 Allocate resources and train the staff

 

 

• A list of the employees who will work within the ISMS

• All of the ISMS procedures to use for identifying what type of training is needed and which members of the staff or interested parties will require training

• Management agreement to the resource allocation and the training plans.

 

12 Monitor the implementation of the ISMS

 

 

To perform management reviews, ISO/IEC 27001 requires the following input:

 

• results of ISMS internal and external audits and reviews

• feedback from interested parties

• techniques, products, or procedures which could be used in the organization to improve the effectiveness of the ISMS

• preventative and corrective actions (including those that might have been identified in previous reviews or audits)

• incident reports, for example, if there has been a security failure, a report that identifies what the failure was, when it occurred, and how it was handled and possibly corrected.

• vulnerabilities or threats not adequately addressed in the previous risk assessment

• follow-up actions from previous reviews

• any organizational changes that could affect the ISMS

• recommendations for improvement

 

13 Prepare for certification audit

 

 

• All of the documents that you created in the preceding steps.

• Records from at least one full cycle of management reviews, internal audits, and PDCA activities, and evidence of responses taken as the result of those reviews and audits.
