Download Securing Converged IP Networks: New Requirements for ICT by Macaulay T. PDF

By Macaulay T.

Info and communique know-how (ICT) networks vary from IT networks simply because they mingle facts resources with resources resembling voice, leisure, media, actual protection, and extra. IP convergence represents either a brand new enterprise relevant and a essentially new defense paradigm. the continuing shift in marketplace terminology from IT to ICT exhibits the conclusive acceleration of IP convergence. Securing Converged IP Networks explores this adoption of ICT terminology by way of huge firms and introduces ICT defense as an self sustaining thought. This e-book makes an attempt to facilitate the beginning of a bigger dialogue that facilities round how ICT affects the sector of expertise safety and insurance.

Traditional organization of threats is appropriate when assessing a relatively granular application, system, or process; however, when considering and organizing multi-dimensional, asset-level threats and risks, the use of the NIST classification scheme is more manageable and in fact intended for this purpose. USE OF QUALITATIVE METRICS The previous chapter had compared and contrasted qualitative metrics with quantitative metrics and put forward the opinion that quantitative metrics were more sophisticated and should be used as much as possible given resource constraints.

The use of quantitative metrics is much less likely to revert to a qualitative measure if the application is the measurement of the converged sensitivity of IP assets. This holds true for the simple reason that the converged assets all have significant commonality 4 Enterprise Risk Management—Integrated Framework: Framework, COSO, Sept 2004, pg 52. © 2006 by Bell Security Solutions Inc. Chapter 2: Converged Sensitivity and Enterprise Risk Management 41 Figure 1: Quantitative metrics from different lines of business.

Insurance companies can leverage the metrics systems developed by organizations to price the cost of insurance in place of safeguards. Because an insurance company can aggregate the ICT risks across a wide range of clients, they can offer a more costeffective solution to managing some share of most organizations ICT convergence risks. The question is: What is this balance? The answer is related to what types of assets have been converged and what is the nature of the organization. © 2006 by Bell Security Solutions Inc.
