In some cases, architecture projects will be stand-alone. In other cases, architectural activities will be a subset of the activities within a larger project. In either case, architecture activity should be planned and managed using accepted practices for the enterprise. Conduct the necessary procedures to secure recognition of the project, the endorsement of corporate management, and the support and commitment of the necessary line management.
Try the following tried-and-trusted almost universal spreadsheet-based method to evaluate your options and choose the tools, methods, software, cars, partners, holiday destinations, political parties, employers, employees, careers, lifestyles, widgets First shortlist and look over the available methods and tools, thinking carefully about your requirements.
What do you expect the method or tool to achieve for you? Are there any things that your would want your chosen method or tool not to do e.
Consider aspects under headings such as: Few information security or risk management professionals would recommend truly quantitative analysis of information risks in all circumstances due to the shortage of reliable data on incidents probabilities and impactsalthough they are potentially useful in some more narrowly-defined situations.
Furthermore, which information assets are you concerned with? Will you be completing the analysis just once or repeatedly, and if so how often?
If you intend to gather and analyze vast amounts of data over time, you will probably prefer tools based on databases rather than spreadsheets; Maintainability and support: Clearly, therefore, they vary in the amount of technical expertise required to install, configure and maintain them. Commercial software having flexibility as a key design goal may give the best of both worlds; Usability: Some attempt to reduce the information gathering phase to simplistic self-completion questionnaires for risk non-specialists, others require competent risk analysts to collect the data; Value: Purchase price is just one factor.
An expensive tool may be entirely appropriate for an organization that will get loads of value from the additional features.
A cheap or free tool may prove costly to learn, difficult to use and limited in the features it offers Your value judgment and final selection is the end result of the evaluation process.
You may even decide to adopt more than one for different situations and purposes! Now write down your evaluation criteria, preferably as rows in a spreadsheet. Finally, insert mathematical functions to multiply each score by the corresponding weight and total each column, and your spreadsheet is ready to support the next step: You are now all set to write your investment proposal, management report or whatever, adding and referring to the completed evaluation spreadsheet as an appendix.
Those evaluation comments repay the effort at this stage. Consider incorporating sample reports, screenshots etc. The information it contains the criteria, the weightings, the scores and the comments is valuable and deserves protection.
Consider the information risks! If your organization already does some form of risk analysis or assessment of its information security or indeed other risks, it is generally worth adopting the same or a similar approach at least at the start.
Your colleagues are likely to be more comfortable with what they know, and hence it should be easier to get them to focus on the analysis rather than the method being used. Within reason you can also pick out useful parts of methods or processes piecemeal, rather than necessarily adopting the entire set.
Remember, risk analysis is a tool, a step on the way not a destination in itself. The point is that conventional arithmetic does not work correctly with such numbers.
Numeric values such as 1, 2 and 3 indicating counts or quantities of the instances of something are called cardinal numbers. The second value 2 indicates exactly twice the amount indicated by the first 1while the third value 3 indicates exactly three times the first amount.
Conventional arithmetic is applicable to cardinals. These ordinal numbers tell us nothing about how fast the winner was going, nor how much faster she was than the runners-up: It is entirely possible that runner number 3 finished first, while runners 1 and 2 crossed the line together.
The fourth entrant might have hurt her knee and dropped out of the race before the start, leaving the fourth runner as number 5! In this case, these are nominal numbers, labels that just happen to be numeric. Phone numbers and post codes are further examples.
Again, it makes no sense to multiply or subtract phone numbers or post codes because they do not indicate quantities like cardinal values do. If you treat a phone number as if it were a cardinal value and divide it by 7, all you achieved was a bit of mental exercise: If you ring that number 7 times, you still will not be connected!
Standard arithmetic makes no sense at all with nominals. When we convert ordinal values such as low, medium and high, or green, amber and red, risks into numbers, they remain ordinal values, not cardinals, hence conventional arithmetic is inappropriate.The growing dependence of critical infrastructures and industrial automation on interconnected physical and cyber-based control systems has resulted in a growing and previously unforeseen cyber security threat to supervisory control and data acquisition (SCADA) and distributed control systems (DCSs).
An ability and capacity acquired through deliberate, systematic, and sustained effort to smoothly and adaptively carryout complex activities or job functions involving ideas (cognitive skills), things (technical skills), and/or people (interpersonal skills).
