Open source software: analysis of available reliability models keeping security in the forefront

The relatively new Open Source Software (OSS) concept has brought about a tremendous stir in the arena of software development and related fields. But one cannot deny the fact that any kind of revolution demands multiple level of checks and balances to make sure things do not go out of hand. All the utilities and the pluses or the advantages of the OSS might get nullified in case its reliability estimation being not carried out in an appropriate and required manner. Presently, there are a large number of models available for the purpose, proposed by esteemed authors the world over. An effort has been made to review maximum possible and compare their strengths and limitations keeping them side by side. The focus of different models/methods has been different. Some depend upon aspects like maturity, durability, and strategy of the firm. While there are few, that relies on functional aspects of the assessment process. The comparison of the different methodologies may be made in different ways with different attributes in focus. This paper shall try and simplify the task of the users in choosing the right model with right approach for the specific required Open Source Software. The comparison has been compiled and put in the form of a table to make the understanding simpler and future scope has been added in the end to invite suggestions, recommendations and further studies on the subject.
