Organizational Roles and Responsibility

A security role is the part an individual plays in the overall scheme of security implementation and administration within an organization.

The following roles are presented in the logical order in which they appear in a secured environment:

Apart from these, Auditor is another role is responsible for reviewing and verifying that the security policy is properly implemented and the derived security solutions are adequate.

Case Study:

For example, say that a data owner requests more room on a system for the storage of data. The data owner strongly believes that the new data being collected will help the sales team be more efficient. However, storage on the system owner’s asset is at a premium. The system owner is unwilling to allow the data owner to use the amount of space he has requested. In this case, the business/mission owner would need to review both sides and decide whether collecting and storing the new data would result in enough increased revenue to justify the cost of allowing the data owner more storage space. If so, it may also be necessary to invest in more storage media for the system or to move the data to another system that has more resources available. But keep in mind that moving the data would possibly involve another system owner.

Security professionals should always be part of these decisions because they understand the security controls in place for any systems involved and the security controls needed to protect the data. Moving the data to a system that does not have the appropriate controls may cause more issues than just simply upgrading the system on which the data currently resides. Only a security professional is able to objectively assess the security needs of the data and ensure that they are met.
