Security Concepts, Developments, and Future Trends

Introduction

These days are called the knowledge era, and every day we hear about new development and an invented new technology. New technology is always brings new threats; this will lead to invent a new counter measure to protect our society from these new threats. Perfect security does not exist, and security strength depends on the weakest ring in the security chain.

Computers and communications are still suffering from their poor security systems that can't stand against the risks of losing or destroying their data files and folders, intrusion of the unauthorized users and the malfunction of the instruments. These risks can't be ignored; in most organizations protection is still far away from serious actions due to the following reasons (Tanenbaum and Wetherall, 2010):

• •

  Un-Proper Security Systems: Most techniques that distinguish authorized users are of equal effect on hindering the unauthorized users.

• •

  Some Organizations Pride that They Are Protected: Several computer crimes are uncovered because organization managers hide such crimes to keep the image of their organizations undistorted.

• •

  Downloading the Technique for Security Problem: It should be always recognized that security is human problem rather that a technological one.

• •

  Threat from Inside the Organization: Most of computer and data threats come from inside the organizations rather than from outside. The computer hackers are most likely one of your employees that receive his/her salary from your organization and not a person who lives away from you.

• •

  The other threat may come from an employee who previously was working for your organization recently, therefore the best security techniques do not usually depend on the technology but depend and focus on the human element.

• •

  Precaution from the problem is not enough, instead, as usual, it is essential to take one step towards the problem-solving given that such step should not be the last one.

• •

  There are always persons believe that there is no issue that is so called “security”.

Of course, professionals are still enjoying an important responsibility because they should determine the nature of their organizations data and threat types that face their organizations. Also, they should set and execute plans to protect their data from such threats. These are the important objectives and they always need a high level of technological knowledge. In the realms of computers and communications, even when completing such high professional objectives, they are insufficient to keep computers and communications security (Stallings, 2004).

Basic Principles In Security System Design

Before discussing the basic principles of the security system design, the common goals that contribute in setting the essential corner stone for the security system design should be identified. The following points may represent essential principles when designing security system:
