2. Introduction
 ISO 27001 is the international standard describing best practice for an Information
Security Management System (ISMS).
 An ISMS is a framework of policies and procedures that includes all legal, physical
and technical controls involved in an organisation's information risk management
processes.
 Being ISO 27001 approved is a certification which shows that the business has
defined and implemented effective Information security processes.

With increasing fines for personal

to ensure compliance with
legislative requirements, such as
the UK Data Protection Act

management of information security
risks, which ensures you take into
account your legal and regulatory
requirements

regulations
• Reduces likelihood of facing prosecution and
fines

damaging your reputation

your information and put in place
security measures to manage or
reduce them
• Protects your reputation
• Provides reassurance to clients that their
information is secure
• Cost savings through reduction in incidents

Lack of confidence in your
organizations ability to manage
information security risks

risks to information security and
implementing appropriate
management and technical controls
• Confidence in your information security
arrangements

Difficulty in responding to rising
customer expectations in relation
to the security of their information

common set of policies, procedures
and controls are in place to manage
risks to information security

security requirements

• Improved information security awareness
• Shows commitment to information security at
all levels throughout your organization
• Reduces staff-related security breaches
