Why Do We Need Internet Security? PDF Print E-mail

Most of the time when we start to communicate using computer with another computer, we are taking a risk. This risk perhaps may worsen when there is no protection. Thus, with the use of internet security, the computer's internet account and files from the computer are protected from any intrusion of any unknown users. Basically, it works well by protecting the computer through passwords, changing file permissions and backing up computer's data.

When it comes to the use of IT systems, internet security is very important to the business users because it makes them feel secured and confident from any cyber criminal attacks knowing that when they attack the IT system, it can be very profitable. This implies that business users need to be very vigilant from any attacks that may come to their way. In making decision on how to enhance and improve the system, security needs to be held from its requirements.

Before an internet security fully works, it should be fluent in the four major aspects which are: penetration testing, intrusion detection and incidence response. Also, it must be legally complied with the law.

A number of the useful programs contain features with hidden malicious intent. The following are some of the programs:

• Malware is the general term used for any malicious software designed. It is commonly used to damage or infiltrate a computer program or any other programmable device and system such as the home or office computer system, networks, mobile phone, PDA, automated device, robots, or any other devices that are sufficiently complex.

• Viruses are programs that enable to replicate their own structure or effect by incorporating itself to the existing files or structures on a penetrated computer. Moreover, it usually contains a malicious or humorous payload designed to threaten or alter the actions or data of the host system or device without consent. The common example of it is by deleting or corrupting the information from its owner.

• Trojan Horse or Trojan are programs that are stealing information, altering it or causing difficult problems on the computer or other programmable system or device by just pretending to do nothing.

• Spyware are programs that secretly keep an eye on the keystrokes or any other activity on the computer system and report the information to others without consent.

• Worms are programs that replicate itself on an extensive computer network. Thus, it also performs some malicious acts that can eventually affect the whole system of the economy.

• Bots are programs that use the resource of a computer system by taking over it in a network without consent, and transmit that information to others who controls the Bots.

The different concepts above can overlap and be combined together. Thus, the terminologies, as well as the dangers involved, are continually developing.

In protecting the computer or any other programmable device/system, Antivirus programs and Internet security programs are commonly used to guard from any malware

Such programs are commonly used to identify and extinguish viruses. When purchasing Anti-virus software by downloading through Internet, a caution should be done since not all programs are effective as compared to others in finding and eliminating viruses or malware. Additionally, when downloading anti-virus software over the Internet, buyers should be careful because some websites may say that they are providing the best protection from malware, but in reality, they are trying to install malware on your computer by pretending to be something else.
