ISMS implementation

First of all as the standard says, you need to "establish, implement,
operate, monitor, review, maintain and improve a documented ISMS".

So, you need to hire ISO27001 consultants in order to do the above tasks.
They will conduct internal audits, gap analysis and so on.

When you have all the documentation required,
You can start the certification process.

You will start a "Stage 1" audit wich deal only with documentation issues.
And this is accomplished by a IRCA Auditor in order to certificate your
ISMS. This is called a third party audit.

At the final of the audit you will receive observations and non-conformity
issues (major or minor) that you need to resolve.

Then when you resolve the above, you are ready to a "in site audit" which is
called "Stage 2", here the IRCA auditor will evaluate the ISMS PDCA process,
so they will look for ISMS policy, internal audit reviews, risk acceptance
criteria, risk assessment results, management commitment, and so on.

So, you need to start hiring ISO27001 Lead Auditors.

Hope this helps.

ISO 27001 benefits

Competitive advantage
increasingly organisations you do business with will want to know how safe your IT systems are.

Demonstrating your capability
you will be able to make a public statement of capability without revealing your security processes.

Minimising risk
ensures controls are in place to reduce the risk of security threats and to avoid system weaknesses being exploited.

Compliance with legislation
compliance provides a process whereby existing and potential legislation is identified.


It is becoming increasingly critical that information security is given the attention and level of importance it deserves. Most organizations are now absolutelyy dependent upon their information and business systems, so much so that serious disruption can mean disaster or critical loss.

ISO17799 is the only internationally accepted worldwide standard/code dealing comprehensively with these issues. Purchasing this standard is a good first step, but as the standard is by necessity a comprehensive and therefore a reasonable complex document, guidance is often necessary to help organizations decide where to start and what priorities should be applied to the implementation process.

The ISO 17799 Toolkit was of course introduced to solve many of these issues in one step. As well as containing both parts of the standard, it also includes a full set of compliant policies ready for implementation, a road map for potential certification of the organization, an audit kit for network based systems, a business impact analysis questionnaire together with many other supportive items (eg: a disaster recovery kit, a management presentation and an IS glossary). This toolkit represents extremely good value as it can enable organizations to commence work with the introduction of vital security aids without reference to expensive external consulting resources.

However, even armed with a support kit such as this, it is important to understand that the key to the standard is PROCESS... the creation and maintenance of a robust ISMS. This is occasionally overlooked, as some organizations simply adopt a tick list from the first part of the standard (ISO17799). This is certainly a good stride forward, but is by no means the end of the journey.

When first considering the standard, therefore, it should be understood that the path forward will certainly include enhancement and improvement of security, but it will largely be driven via the creation and maintenance of information security management systems and supporting procedures.
