Relationships
Configuration
performance security management relationships are varied, so I will
give you an overview of each to give you an idea of the
relationship. Remember this is the process view not the technical
view!
Configuration
Performance Security Management Relationships - Security
Management
The Security
Management function interfaces with IT Service Management processes
where security issues are involved. Such issues relate to the
Confidentiality, Integrity and Availability of data, as well as the
security of hardware and software components, documentation and
procedures.
For example, Security
Management interfaces with Service Management to assess the impact
of proposed Changes on security, to raise RFC’s in response to
security problems; to ensure confidentiality and integrity of
security data and to maintain the security when software is released
into the live environment. Where it gets this information from is in
the CMDB and performance management ensures the capacity is there
when needed.

Performance management
focuses on the iterative cycle of Monitoring, analyzing, Tuning and
Implementation. It is important that the utilization of each
resource and service is monitored on an on-going basis to ensure the
optimum use of the hardware and software resources, that all agreed
service levels can be achieved, and that business volumes are as
expected.
The monitors should be specific
to particular operating systems, hardware configurations,
applications, etc. It is important that the monitors can collect all
the data required by the Capacity Management process, for a specific
component or service.
The data collected
from the monitoring should be analyzed to identify trends
from which the normal utilization and service level, or baseline,
can be established. By regular monitoring and comparison with this
baseline, exception conditions in the utilization of individual
components or service thresholds can be defined, and breaches or
near misses in the SLA’s can be reported
upon. Also the data can be used to predict future resource usage, or
to monitor actual business growth against predicted growth.
The analysis of the
monitored data may identify areas of the configuration that could be
tuned to better utilize
the system resource or improve the performance of the particular
service.
The implementation of any
Changes arising from these activities must be undertaken through a
strict, formal Change Management process. The impact of system
tuning changes can have major implications on the Customers of the
service. The impact and risk associated with these types of changes
are likely to be greater than that of other different type of
changes.

Management
The Configuration
Management system identifies relationships between an item that is
to be changed and any other components of the infrastructure, thus
allowing the owners of these components to be involved in the impact
assessment process. Whenever a Change is made to the infrastructure,
associated Configuration Management records should be updated in the
CMDB. Where possible, this is best accomplished by use of integrated
tools that update records automatically as Changes are
made.
