The research question for this research project is – “How is it possible to calculate IT security effectiveness?”. The aim of this research is to use this reference model to calculate and to optimize major university’s and a small CSP-s (Cloud Service Provider) security posture and their spending’s on security measures. Aim is to develop a reference model to support IT Security team and business side to make reasoned and optimal decisions about IT security and all that with a reasonable number of manhours. In this Graded Security Expert System (GSES) aka Graded Security Reference Model (GSRM) the quantitative metrics of the graded security approach are used to express the relations between security goals, security confidence and security costs. What makes this model unique, is the option to use previous customers security templates/models – cutting the implementation time from 500+ manhours to as low as 50 manhours. The first

component specifications, and key architectural mechanisms are detailed. The Logical Architecture provides a detailed "blueprint" from which component developers and component users can work in relative independence. Logical Architecture. Model System Behavior Execution Architecture An Execution Architecture is created for distributed or concurrent systems. The process view shows the mapping of components onto the processes of the physical system, with attention being focused on such concerns as throughput and scalability. The deployment view shows the mapping of (physical) components in the executing system onto the nodes of the physical system. Architecture views 2. Business Architecture A formalized model of what the business looks like, in terms of IT. Information Architecture Logical description of the translated Business Architecture in IT terms. The IA is on high level in terms of functionality and data management.
1950 Engineering Research Associates of Minneapolis built the ERA 1101, the first commercially produced computer; the company's first customer was the U.S. Navy. 1951 The UNIVAC I delivered to the U.S. Census Bureau was the first commercial computer to attract widespread public attention. Although manufactured by Remington Rand, the machine often was mistakenly referred to as the "IBM UNIVAC." Remington Rand eventually sold 46 machines at more than $1 million each. The first AI program to run in the U.S. was also a checkers program, written in 1952 by Arthur Samuel of IBM for the IBM 701. 1952 Heinz Nixdorf founded Nixdorf Computer Corp. in Germany. It remained an independent corporation until merging with Siemens in 1990. 1953 IBM shipped its first electronic computer, the 701 Speedcoding: John Backus. 1954 Texas Instruments announces the start of commercial production on silicon transistors.
EBCDIC (Extended Binary Coded Decimal Interchange Code) UNICODE (Extended ASCII) Each pixel contains a value representing some shade of gray. The more shades of gray possible, the more memory will be needed. Instructions: Must be stored within the computer before use. Must be stored in binary form. A set of binary instructions is called a program. Program: A collection of instructions for the computer to perform one by one. Machine Language: The language of the computing machine. All instructions must be in the form of binary numbers (binary code). Stored-program Computer: Also known as the von Neumann-type computer. Has memory - a place to keep both: instructions (ie program) and the needed information (ie data)

Cuisine of South Africa has had a variety of sources and stages: · Cookery practised by indigenous people of South Africa such as the Khoisan and Xhosa- and Sotho-speaking people · Settler cookery introduced during the colonial period by people of Indian and Afrikaner and British descent and their slaves and servants - this includes the cuisine of the Cape Malay people, which has many characteristics of Malaysia and Java, and recipes from neighbouring colonial cultures such as Portuguese Mozambique. Indigenous cookery traditional South African cuisine In the precolonial period, indigenous cuisine was characterized by the use of a very wide range of fruits, nuts, bulbs, leaves and other products gathered from wild plants and by the hunting of wild game. The domestication of cattle in the region about two thousand years ago by Khoisan groups enabled the use of milk products and the

VEEBITEENUS o A Web service is a service offered by an electronic device to another electronic device, communicating with each other via the World wide web. In a web service, web technology such as the HTTP, originally designed for human-to-machine communication, is utilized for machine-to-machine communication, more specifically for transferring machine readable file formats such as XML and JSON. In practice, the web service typically provides an object- oriented web based interface to a database server, utilized for example by another web
