Question

Configuration management is a process of requesting, tracking, and approving all changes to a system. It not only involves the identification, control, and auditing of all changes made to a system, it also pertains to all hardware, software, network, and any other changes that pertain to security.

Provide an example of a situation where change control was not followed that resulted with a disastrous result. (This may or may not be real)

Then identify the necessary steps that should have been included as part of the change control process.

Answer 1

• Configuration management (CM) could be a systems engineering method for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its necessities, design, and operational info throughout its life.
• The CM method is wide employed by military engineering organizations to manage changes throughout the system lifecycle of complicated systems, like weapon systems, military vehicles, and knowledge systems.
• CM is that the observe of handling changes consistently so a system maintains its integrity over time. CM implements the policies, procedures, techniques, and tools that manage, judge projected changes, track the standing of changes, and maintain a list of system and support documents because the system changes.
• CM programs and plans give technical and body direction to the event and implementation of the procedures, functions, services, tools, processes, and resources needed to with success develop and support a fancy system.
• Throughout system development, CM permits program management to trace necessities throughout the life-cycle through acceptance and operations and maintenance. Changes square measure inevitable once software system is constructed.
• A primary goal of software system engineering is to enhance the convenience with that changes may be created to software system. Configuration management is all concerning modification management.
• Each computer programmer must fret with however changes created to figure merchandise square measure half-tracked and propagated throughout a project. To confirm that quality is maintained the modification method should be audited. A software system Configuration Management (SCM) arranges defines the strategy to be used for modification management.

• The standard software system configuration management (SCM) method is looked upon by practitioners because the best resolution to handling changes in software system comes.
• It identifies the useful and physical attributes of software system at varied points in time, and performs systematic management of changes to the known attributes for the aim of maintaining software system integrity and traceability throughout the software system development life cycle.

• Configuration identification is that the method of characteristic the attributes that outline each side of a configuration item. A configuration item could be a product   that has an end-user purpose.
• These attributes square measure recorded in configuration documentation and baseline. Base lining associate degree attribute forces formal configuration modification management processes to be settled within the event that these attributes square measure modified.
• Configuration modification management could be a set of processes and approval stages needed to vary a configuration item's attributes and to re-baseline them.
• Configuration standing accounting is that the ability to record and report on the configuration baselines related to every configuration item at any moment of your time.
• Configuration audits square measure broken into useful and physical configuration audits. They occur either at delivery or at the instant of effecting the modification.
• A useful configuration audit ensures that useful and performance attributes of a configuration item square measure achieved, whereas a physical configuration audit ensures that a configuration item is put in accordance with the necessities of its elaborate style documentation.

• The Information Technology Infrastructure Library specifies the employment of a Configuration management system or Configuration management info as a method of achieving business best practices for Configuration Management.
• CMDBs square measure accustomed track Configuration things (CIs) and therefore the dependencies between them, wherever CIs represent the items in associate degree enterprise that square measure value chase and managing, like however not restricted to computers, software, software system licenses, racks, network devices, storage, and even the elements among such things.

• For info assurance, CM may be outlined because the management of security measures and assurances through management of changes created to hardware, software, firmware, documentation, test, take a look at fixtures, associate degreed take a look at documentation throughout the life cycle of a system.
• CM for info assurance, generally remarked as Secure Configuration Management, depends upon performance, functional, and physical attributes of IT platforms and merchandise and their environments to see the suitable security   and assurances that square measure accustomed measure a system configuration state.
• For instance, configuration necessities could also be totally different for a network firewall that functions as a part of associate degree organization's net boundary versus one that functions as an enclosed native network firewall.

• Change management is presently employed in varied merchandise and systems . For IT systems it's a serious side of the broader discipline of modification management.
• Typical examples from the pc and network environments square measure patches to software system merchandise, installation of latest in operation systems, upgrades to network routing tables, or changes to the electric power systems supporting such infrastructure.
• There is wide overlap and confusion between modification management, configuration management and alter management. The definition below isn't however integrated with definitions of the other.,
• Certain specialists describe modification management as a group of six steps

• Record / Classify
• Assess
• Plan
• Build / take a look at
• Implement
• Close / Gain Acceptance
• The impact tax assessor or assessors then build their risk analysis usually by responsive a group of queries regarding risk, each to the business and to the method, and follow this by creating a judgment on United Nations agency ought to perform the modification.
• If the modification needs over one form of assessment, the top of the modification management team can consolidate these. Everybody with a stake within the modification then should meet to see whether or not there's a business or technical justification for the modification.
• The modification is then sent to the delivery team for coming up with. Management can assign the modification to a selected delivery team, sometimes one with the particular role of concluding this particular form of modification.
• The team's initial job is to arrange the modification well moreover as construct a regression arranges just in case the modification has to be backed out.
• Once the shopper agrees that the modification was enforced properly, the modification may be closed
