INTRODUCTION Computer security is now an important area for any network administrator, systems analyst, information technology technician, databases administrator to the computer scientist. Although this list shows the professionals dabbling in Information Technology, it should not be misconstrued that the average computer user at home should not be concerned about computer security. A computer, be it a personal computer, a laptop or a simple netbook, is one of the features that adorn any home. Mobile phones too should not be excluded whenever the issue of computer security crops up since they are the latest targets for cyber criminals (SANS Institute). Inevitably, this has the led to the development and growth of a complex industry centered on Computer security. The actual threats to computer security are many. These threats emanate from the state of technology of today’s computer, computer users who are ignorant of the ways to secure their computer machines, the current trend of data distribution without any restraints, and the advent of the mobile office (Vacca, J., 2009, 3-4). Firstly, the modern PC today has evolved from the Abacus, an implement that was used for simple mathematical calculations (Sadiku and Obiozor) to a powerful machine that can store and manipulate data (Vacca. J., 2009, 3). Sadiku and Obiothor’s work shows the evolution of the computer starting from the Abacus, to the machines made by such inventors as Blaise Pascal, Gottfried Wilhelm von Leibniz, Charles Babbage and Thomas of Colmar, to the electromechanical computer using punched cards, right through to the first digital computer using Integrated Circuits. It is the latter development, more so in the manufacturing of the Integrated Circuits, which has... ... middle of paper ... ...rity Trends of the Coming Year”.

President Obama has realized the seriousness of the upcoming threats and turned the government focus more toward defending the information and communications infrastructure and In May 2009, he issued a request from top to bottom review of the current situation. The report titled the Cyberspace Policy Review includes strategy, policy, and standards regarding the security of and operations in cyberspace. According the white house’s cybersecurity foreign policy, the Cyberspace Policy Review highlighted two objectives and ten near-term actions to support the cybersecurity strategy.
In taking a wide overview of the computer world today, it is very easy to identify possible security risks. Especially in a connected network of worldwide computers, the limitless stream of bytes and data may invite viruses and hackers into any one single computer. According to PC Magazine Online, “Intel execs say the computer industry is lagging in support of data-security initiatives.”1 The difficulty lies sometimes in predicting areas of security weakness. Sometimes seemingly secure code may be subject to innovative attacks which can compromise security.
Computer security is a growing concern with the onset of always-on connections in the home and the emerging global network. More and more people become connected everyday. The reliance on computers in our daily lives has increased the need for security and has shifted the ethical line for hackers and hacking.
Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
Lastly, the application layer (Layer 7) supplies services to application procedures and threats are static passwords and SNMP private community strings (Holl, 2003). Organization will need to enforce encryption to limit the exposure of personal information, ensure that patches are installed for applications, patching and is performed on all network and hardware devices, hardening of operation system and implements secure authentication methods (Baker & Wallace, 2007). Additionally, a quality anti-virus is utilized on workstations, servers and other devices connected to the organization IT infrastructure. All types of attackers discussed in this paper are applicable. Black hat hackers and cyber terriorist will control exploit vulnerabilities in networks and application systems that are not properly patch as well as malware writer
Information Security Analysts are the guardians of information systems, they arrange and execute efforts to establish safety to shield an association's PC frameworks and systems from invasion and cyberattacks. Analysts help companies avoid, screen and react to breaches and cyberattacks. Analysts have to constantly adjust in order to stay ahead of cyber attackers, stay exceptional knowledgeable on the most recent strategies assailants are utilizing to penetrate PC frameworks and on IT security. Experts look into new security innovation to choose what will most successfully ensure the safety of the company they work for. This may include going to cybersecurity meetings to hear first hand research from different experts who have encountered new sorts of assaults.
With our world today, technology has become a huge part of our lives. We use it from the simple tasks we do to the most complex and important ones. For this reason, we should take measures into making sure that our files and information are safe. To do this, we could simply start with creating complex and different passwords for each website we use. Next, we could back up our data in case of an attack from a hacker or a virus. Lastly, we need to remind ourselves to update the software we use and most especially our antivirus. These simple steps are what are needed for a better protection in the world of our growing technology.
The increasing proliferation and complexity of technology are creating new "opportunities" for cyber criminals to exploit. In addition, cyber crime techniques are getting ever more sophisticated. For businesses, this adds up to an increasingly more dangerous cyber threat environment. It doesn't help that human factors add to the risk. These include simple blunders, such as exposing sensitive data to the open Internet, as well as network security misconceptions and oversights. Here are two network security mistakes that invite devastating data breaches:
Computer are becoming more and more useful in our activities. It is an indispensable device. We uses it for our study, finding a job, pay a bills, earning money, entertainment and more. Although the purpose for personal, business or government, computer security is one of the most important things.
Hacking has become such a problem in today’s computer dependent society that stronger measures must be implemented to stop hackers, and if hackers are still successful, they should be severely punished. Hackers are a problem because with the amount of businesses and corporations we depend on ...

Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
capacity and performance. However, as networks enable more and more applications and are available to more and more users, they become ever more vulnerable to a wider range of security threats. To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks.
