Conceptual Framework

Enterprise Information System Security

Security Policy

Security Awareness

Access Control

Top Level Management

Support

Corporate Governance

Implementation

Pillar 1: Security Policy

Set rules for behavior

Define consequences of violations

Procedure for dealing with breach

Authorize company to monitor and investigate

Legal and regulatory compliance

“Information Security Policy is not an option, it’s demanded from the top of the house on down, it’s board approved, accepted by regulators, and executed throughout the organization. ”

Excerpt from interview:

Pillar 2: Security Awareness

Continued education

Collective and individual activities

Formal classes, emails, discussion groups

Employee compliance

“In training, we tell employees

that we are tracking them,

when we are not. It’s a

deterrent. The fact is we have

to use implied security in

addition to actual security. ”

Excerpt from interview:

Pillar 3: Access Control

Limit information

Access linked to job function

Restrict information not relevant to position

Management of access rule changes

Have you ever accessed information on a system that was not relevant to your role?
