“Working with Sapphire enabled us to streamline our current security procedures. Their guidance allowed us to look at our existing procedures and focus on the important aspects of the ISMS, for example proper risk analysis and to quantify and qualify the security of every asset.”

What is ISO 27001:2005?

ISO 27001:2005 was formally a British standard (BS: 7799) and is the de-facto international standard on establishing, operating and maintaining and Information Security Management System (ISMS).

The standard is structured into two sections 1) S.4-S.8 which is the mandatory sections of the standard and details specific processes and policies which must be adhered to in order to gain formal certification and 2) Annex A of ISO 27001:2005 which covers the following 11 security sections:

• Security Policy
• Organisation of information security
• Asset management
• Human resources security
• Physical and environmental security
• Communications and operations management
• Access control
• Information systems acquisition, development and maintenance
• Information security incident management
• Business continuity management
• Compliance 

These 11 security sections are made up of 133 information security control objectives, not all 133 controls need to be implemented by an organisation in order to gain certification, an organisation should select the controls it requires on the back of a formal risk assessment and also on what it deems as best practice for the industry it operates in.

ISO 27002 provides a strong and expanded (on Annex A ISO 27001:2005) framework for information security management.

Why do Organisations Implement an ISMS?

Intellectual property and other sensitive or business critical information is the life blood of companies and with an ever increasing number of security breaches being reported, companies need to protect themselves and their customers.

The ability to respond quickly to any information security breaches or incidents is one of the key clauses in ISO27001:2005. The ability to minimse the opportunity for incidents to occur is a major advantage for an organisation and it’s service resilience.

Organisations realise the risks to its information is the fastest growing business issue. Continuous monitoring for constant vigilance is now a business or service necessity and a culture of security is vital for organisations to survive in the modern world and the rapidly changing environment.

Compliance to the standard is becoming an increasing requirement from customers and the government.
