In this chapter, you learn about the following topics: Fundamental concepts in network security, including identification of common vulnerabilities and threats, and mitigation strategies Implementation of a security architecture using a lifecycle approach, including the phases of the process, their dependencies, and the importance of a sound security policy The open nature of the Internet makes it vital for businesses to pay attention to the security of their networks. As companies move more of their business functions to the public network, they need to take precautions to ensure that the data cannot be compromised and that the data is not accessible to anyone who is not authorized to see it.
Key concepts you will need to understand: IT management is responsible for the acquisition and maintenance of the information architecture. This includes networking devices, servers and operating systems, data storage systems, applications, and the standards and protocols associated with network communication.
IT managers must define the role and articulate the value of the IT function. This includes the IT organizational structure as well as operational practices. The IT management functions are generally divided into two functional areas: Projects are normally a one-time effort with a fixed start, duration, and end that reach a specific deliverable or objective.
The following are line management functions: Sets up system accounts, installs system-wide software, and so on. The IT functional areas are responsible for the computing infrastructure. This includes computer hardware, network hardware, communications systems, operating systems, and application software and data files.
IT management must understand how these elements work together and must establish a control infrastructure defined functions, policies, procedures, governance that will reduce risk to the organization during the acquisition, implementation, maintenance, and disposal processes.
Organizations should constantly seek to use technology more efficiently and effectively to meet business objectives. This quest will provide a myriad of choices regarding technology and the acquisition, development, implementation, and maintenance of the network as a whole and its individual components.
A clearly defined IT strategic plan combined with acquisition planning, project management, and strong operational practices policies and procedures will ensure two things: First, the IT organization will be aligned with the business strategy and objectives.
Second, IT resources will be used effectively and efficiently. IT managers consistently balance operational issues and the implementation of new technology. This balancing act creates competing priorities: Operational issues usually fall into the "urgent" category, whereas the implementation of new technology falls into the "important" category.
These issues need to be addressed and corrected as quickly as possible to ensure continued operations. If an IT organization allows itself to be driven primarily by urgent issues while putting important issues to the side, it will quickly become a completely reactive environment and will not look forward to properly align technology and business objectives.First, in the area of information systems development, the most common consideration about project success is scope success (Agarwal and Rathod, ).In this type of project, many small changes are expected to be decided upon during the execution of the project.

Separate registrations apply. This is a working draft agenda. Do I need to meet an exact level when assessing a process using COBIT's maturity models, and does this differ from the original CMM approach? The reality is that probably no two COBIT maturity assessments are performed in exactly the same manner.
