    Computer & Network Security   Computer security (also known as cyber security or IT security) is information security as applied to computing devices such as computers and smart phones, as well as computer networks such as private and public networks, including the whole Internet. Traditionally, computer facilities have been physically protected for three reasons:
    • To prevent theft of or damage to the hardware
    • To prevent theft of or damage to the information
    • To prevent disruption of service
     
  • Confidentiality: Confidentiality is the concealment of information or resources. The need for keeping information secret arises from the use of computers in sensitive fields such as government and industry.
  • For example, military and civilian institutions in the government often restrict access to information to those who need that information. The first formal work in computer security was motivated by the military's attempt to implement controls to enforce a "need to know" principle. This principle also applies to industrial firms, which keep their proprietary designs secure lest their competitors try to steal the designs. As a further example, all types of institutions keep personnel records secret.  
  • Integrity: Integrity refers to the trustworthiness of data or resources, and it is usually phrased in terms of preventing improper or unauthorized change. Integrity includes data integrity (the content of the information) and origin integrity (the source of the data, often called authentication). The source of the information may bear on its accuracy and credibility and on the trust that people place in the information. This dichotomy illustrates the principle that the aspect of integrity known as credibility is central to the proper functioning of a system.
  •  
  • Availability: Availability refers to the ability to use the information or resource desired. Availability is an important aspect of reliability as well as of system design because an unavailable system is at least as bad as no system at all. The aspect of availability that is relevant to security is that someone may deliberately arrange to deny access to data or to a service by making it unavailable.
  •  
  • Access Control System: Any system designed to prevent and restrict access to users. For example, a primary form of access control is only allowing users who have accounts to login to a system or only allowing the user access to files he or she should be able to see. .
  •   TOP SOME SOURCES OF COMPUTER VIRUS ATTACK The most potent and vulnerable threat of computer users is virus attacks. Virus attacks hampers important work involved with data and documents. It is imperative for every computer user to be aware about the software and programs that can help to protect the personal computers from attacks. One must take every possible measure in order to keep the computer systems free from virus attacks. The top sources of virus attacks are highlighted below:

      Product Life Cycle   Introduction  After a new product/service has been developed and introduced in the market, the different stages through which it passes over time is known as the product/service life cycle. Generally, there are four stages in a product service life cycle namely, launch, growth, maturity, and decline. These four stages are discussed in detail below. Product life cycle (PLC) indicates the sales history of a product over time with its introduction in the market till it dies or ceases to exist as it is no longer relevant.                                              Introduction: This is the first stage in the product life cycle wherein a product or service is introduced in the market. The main aim of marketers at this stage is to increase product/service awareness among customers. An organization can adopt any strategy in the market like skimming or penetration, depending on the size of its operations. Organizations may not earn profits at this stage as they have to cover the costs incurred.   Growth: The brand awareness created in the earlier stage helps an organization to earn revenues and reap profits at this stage. The markets continue to grow as more and more customers buy the service. Further organizations invest in promotional activities with the aid of profits. Thus, marketers strive to increase their market share and also maximize their profit margins.   Maturity: Due to high competition and limit growth in this stage, companies try to maintain their market share. Marketers try to modify their services to tap any potential for growth. They also try to increase the quality and efficiency of their services to maintain customer loyalty. They should be discreet in deciding their marketing expenses and in allocating their finances.   Decline: This is the final stage in the life cycle of a product/service and is characterized by reduction in demand and consequently a decrease in revenues and profit margins. The introduction of new services in the market or changes in customer preferences reduces demand.
