Approaches to Information Security Implementation

The implementation of information security in an organization must begin somewhere, and cannot happen overnight. Securing information assets is in fact an incremental process that requires coordination, time, and patience. Information security can begin as a grassroots effort in which systems administrators attempt to improve the security of their systems and software developed by software development companies in India.
This is often referred to as a Bottom-Up Approach. The key advantage of the bottom-up approach is the technical expertise of the individual administrators. Working with information systems on a day-to-day basis, these administrators possess in-depth knowledge that can greatly enhance the development of an information security system. They know and understand the threats to their systems and the mechanisms needed to protect them successfully. Unfortunately, this approach seldom works, as it lacks a number of critical features, such as participant support and organizational staying power.
The Top-Down Approach—in which the project is initiated by upper-level managers who issue policy, procedures and processes, dictate the goals and expected outcomes, and determine accountability for each required action—has a higher probability of success. This approach has strong upper-management support, a dedicated champion, usually dedicated funding, a clear planning and implementation process, and the means of influencing organizational culture. The most successful kind of top-down approach also involves a formal development strategy referred to as a systems development life cycle.
Information Security: Is it an Art or a Science?
Given the level of complexity in today’s information systems, the implementation of information security has often been described as a combination of art and science. System technologists, especially those with a gift for managing and operating computers and computer-based systems, have long been suspected of using more than a little magic to keep the systems running and functioning as expected and the same way software which is developed by many software development companies in India.
Security as Art:
The administrators and technicians who implement security can be compared to a painter applying oils to canvas. A touch of colour here, a brush stroke there, just enough to represent the image the artist wants to convey without overwhelming the viewer, or in security terms, without overly restricting user access. There are no hard and fast rules regulating the installation of various security mechanisms, nor are there many universally accepted complete solutions. While there are many manuals to support individual systems, there is no manual for implementing security throughout an entire interconnected system. This is especially true given the complex levels of interaction among users, policy, and technology controls.
Security as Science:
Technology developed by computer scientists and engineers—which is designed for rigorous performance levels—makes information security a science as well as an art. Most scientists agree that specific conditions cause virtually all actions in computer systems. Almost every fault, security hole, and systems malfunction is a result of the interaction of specific hardware and software. If the developers had sufficient time, they could resolve and eliminate these faults.
The faults that remain are usually the result of technology malfunctioning for any one of a thousand possible reasons. There are many sources of recognized and approved security methods and techniques that provide sound technical security advice. Best practices, standards of due care, and other tried-and-true methods can minimize the level of guesswork necessary to secure an organization’s information and systems.
Security as Social Science:
A third view to consider is information security as a social science, which integrates some of the components of art and science and adds another dimension to the discussion. Social science examines the behaviour of individuals as they interact with systems, whether these are societal systems or, as in this context, information systems. Information security begins and ends with the people inside the organization and the people that interact with the system, intentionally or otherwise. End users who need the very information the security personnel are trying to protect may be the weakest link in the security chain. By understanding some of the behavioural aspects of organizational science and change management, security administrators can greatly reduce the levels of risk caused by end users and create more acceptable and supportable security profiles. These measures, coupled with appropriate policy and training issues, can substantially improve the performance of end users and result in a more secure information system of software development companies in India.
