Software Component Security

Software is a sensitive creation. It is valuable for us. So, we make it secure and protect it. Software security means software protection against unwanted changes.

Software carries a risk of being harmed. There is a danger that one may interfere with normal software functioning. Thus, Software may be forced to behave improperly. Normal Software behaviour can change. Such change can occur if unauthorized access to Software is made.  In other words, Software can be affected if someone without permission can have access. If access to Software is without permission, it means there is no approval for such access.

A step towards Software Security is to restrict access to  Software. We can say that we can permit access in a controlled manner. Permission is granted to authentic users of the Software. Users who are not authentic are not granted access to the Software.


Checking users for Security is called authentication. It is really a verification process. Users are authenticated before they can access Software.

Authentication requires users to verify their identity. 

Authentication is made possible by a security program. Security program is actually an application program. The security program helps in making a software system secure. As a security step, security program is developed to issue passwords. 

Password is given to only selected and trusted users. At the time of login  a user is told to enter the password. The entered password is verified. It is compared with the password that is stored in the system. If the entered password matches the stored password, the authenticity of the user is proven. Now, the access to Software is secure.

Authentication is really helpful. It is a way to achieve Software Security.  Security is important for always  keeping Software in a functional state.

Local-Area Networks

Local-Area Networks ( LANs ) are restricted to a small area. Such Networks may be established within a building. Computers that are part of Local-Area Networks are Personal Computers ( PCs ) or microcomputers. These Computers are connected to each other. Simple communication lines connect these Pers Networks bring people together. When people join  hands teamwork becomes possible. The structural composition of LANs simplifies teamwork. In other words, LAN hardware supports teams having similar processing requirements. LAN Computers readily support personalization of tasks allocated to professionals.  Office staff can work together and share information. This improves the efficiency of the entire workforce. It has been noted that here all the Networked Computers are Personal Computers. They are of equal capacity. Mostly LAN users have similar tasks. If situations allow, a user is independent to access any Computer to serve his purpose. LAN users can exercise the option of secu...

Computers - An Introduction

Computers are man made machines. They are made to work very fast. Working fast they can solve  big and small problems.  Modern science has given us these computers. They are very popular. Computers affect and change lives. They keep us happy.The happiness grows. Computers are quick and smart. Great problem solvers and simplifiers are our computers. They can do our work without stopping. Focus is on doing only what is needed. Not needed, not done.  Computers are  life-less servants. They cannot think or make decisions on their own. They are empowered to work. They are given each and every thing so that they carry out our orders. Orders are respected by computers. The manner in which computers work is wholly dependent on man.  The quality of service provided by computers is remarkable. They are loved by human beings. Computers are known for smart and quick service. Computers do not give wrong results. Correct answers are always given. Questions which are difficult...

Euclid's Algorithm

The Greatest Common Divisor ( GCD ) of  two numbers is a number. The number ( GCD ) causes division of the two numbers. This number ( GCD ) is the greatest number that is possible. This divisor partially forms the two numbers. Adding  the divisor successively may result in formation of the two numbers. One can note that when the divisor is the greatest, the division of the dividend is the sharpest. The division operation is very effective. When the Greatest Common Divisor of two numbers is considered, we think of a number that can cause division of both the numbers. Here the two numbers are unequal. The Greatest Common Divisor causes divisions of the two numbers differently. This is clear from the two different quotient values.  The GCD value is very interesting to note. It relates very well with the two numbers. The GCD of two even numbers is also an even number. The GCD of two odd numbers is an odd number. So, we can say that GCD is an abstraction of the two numbers in ...
