Centralized Security

Centralized security:

Gives concentrated control over changes in security, and strengthen security enforcement
Provides one point for security administration
Makes policies and procedures simpler to develop, enforce, and monitor
Provides a higher level of security by limiting the number and distance of individuals authorized to change security definitions
Allows for more flexible reporting and
Requires fewer security staff members than required by a decentralized organization.

But, centralized security might....

Be less responsive to the user due to logical and physical distance from the user’s environment
Involve longer response times to react to maintenance requests
Require a higher maintenance workload.
