ccna certification cost in pakistan.Configuration and change control should address three main components: processes to minimize system and network disruptions, backup and rollback of undesired changes, and guidance for efficient use of resources and time.Guiding efficient use of resources and time. The following recommendations enable configuration changes to be accomplished in an efficient and secure manner. Ensure that changes are implemented in a sequential manner and are formally tested. Ensure that end users are aware of upcoming changes when necessary. Analyze the effects of changes after they are implemented.Although the change control process varies from organization to organization, there are some set patterns in change management. A typical change control processconsists of 5 steps. Step 1 Request the introduction of a change. Step 2 Document the proposed change. Step 3 Schedule the change. Step 4 Implement the change. Step 5 Report the change to the appropriate parties. By providing security personnel with an organized process, operational security makes it possible to minimize damage to the network.10.4 Network Security Testing10.4.1 Introduction to network security testing10.4.1.1 Network Security TestingAn operational security solution has news that can be determined by testing, without the need to wait for a real wi10.4 Network Security Testing 309threat. Network security testing makes this possible. Network security testing is a test performed on a network to ensure that all security implementations are working as expected. Typically, network security testing is performed during the implementation and operational phases, i.e., after the system has already been developed, installed, and integrated. Security testing provides insight into a variety of manageable tasks, such as risk analysis and contingency planning. It is also important to document the results of security testing and make them available to employees in other IT areas. During the implementation phase, security testing is performed on specific parts of the security system. After a network is fully integrated and operational, perform a SecurityTestand Evaluation (ST&E).ST&E is an examination or analysis of the protections on the operational network. Testing should be repeated periodically and is also required once changes are made to the system. For security systems that protect critical information or protect hosts that are frequently exposed to threats, security testing should be performed more frequently.
