Internal organization

The objective of this category is to manage information security within the organization's overall administrative structure.

Management commitment to information security • Management at all levels should actively support security within the organization with clear direction, demonstrated commitment, and explicit acknowledgement of information security responsibilities. Control includes:

• clear direction and visible support for information security initiatives, including providing appropriate resources for information security controls;
• coordination of information security efforts across the organization, including designation of information security officer(s)and committee(s);
• assuring formulation, review and approval of appropriate organization-wide information security policy;
• periodic reviews of the effectiveness of information security policy, including external review as appropriate, and updating of the policy as needed; and

Authorities: ISO-27002:2005 6.1.1.

Information security coordination • Information security activities should be coordinated by representatives from different parts of the organization with relevant roles and job functions. Control includes:

• assessing adequacy and coordinating implementation of controls;
• ensuring that information security controls are executed in compliance with information security policy;
• proposing methodologies and processes (e.g., risk assessment) subject to management approval;
• evaluating security incident data from across the organization, and recommending appropriate action;
• identifying significant threat and vulnerability changes, and recommending appropriate action; and
• promoting security awareness and training throughout the organization.

Authorities: ISO-27002:2005 6.1.2.

Allocation of information security responsibilities • All information security responsibilities should be clearly defined. Control includes:

• identification and clear definition of assets and security controls for each information facility; and
• identification of the individual responsible for security for each information facility.

Authorities: ISO-27002:2005 6.1.3.; HIPAA 164.308(a)(2);

Authorization process for information processing facilities • A management authorization process for new information processing facilities and capabilities should be defined and implemented. Control includes:

External parties

This category aims to maintain the security of the organization's information and information processing facilities that are accessed, processed, communicated to or managed by external parties.

• a risk assessment to identify any requirements for specific controls, taking into account characteristics of external users, their type of access, and the value and sensitivity of the information involved;
• contractual specification of the terms and conditions of access, including required security controls;
• implementation of all security controls before access is permitted;

Authorities: ISO-27002:2005 6.2.1.

Addressing security when dealing with customers • All identified security requirements should be addressed before giving customers access to the organization's information or assets. Controls considerations are similar to those for external parties.
