When you use your computer to essentially make your life work as you log in to the Internet, you are taking a big gamble with your personal life. When your computer starts to exchange data with other computers through the internet, it becomes troublesome.
When a hacker tries to intrude into your computer and get information or data you have inputted in your computer and fails it would most likely be because of "Internet Security". Some securities issues are concerned with feeling comfortable using their systems. They want to be confident that they are secured from cyber criminals. Fundamental tips on security include creating difficult passwords, back ups, and file permissions. However, this would not suffice because these criminals are sometimes intelligent enough to still break into your computer's data even with this security. So, you should be vigilant and have enhancements about Internet security always be upgraded into your computer.
Fortunately, there are programs which could help prevent these problems of hacking and other types of intrusions. And these are called, "Anti-virus". They are systems specifically built to fight "viruses" or dangerous systems that may have intruded your personal computer. Some examples of these programs which may inflict damage to you and your computer are the following: Viruses, Malware, Worms, Spyware, and etc.
- A virus is a program which copies itself into your computer several times as it penetrates deeper it then makes the system slow down tremendously.
- A malware on the other hand is short for "malicious software". It is basically a spy computer which spies on other computers' information.
Also, there such programs called, "Worms". They are like viruses which copy themselves extensively. And lastly, "Spywares". These are programs which monitor one's activity in the computer - from keystroke to mouse movement in order to report the information to the hacker.
There are a lot more types of programs, so be careful when you are online. Always be safe and have Internet Security.
These Anti-virus programs search and destroy viruses which may be present in your system. These security programs could be bought at your nearest computer shop or online. There are some similar software which offer free service as well. However, these free anti-virus programs may not be as effective as the anti-virus program you have to purchase. Because of their nature of being free, they may not be able to give as good a service as that of one not free. And so you should always be careful when trying to look for a good anti-virus program. In other cases, you should also be vigilant in downloading these programs because some of them have hidden deep inside the files, dangerous viruses which may slow down your computer tremendously and at the same time steal information from you.
There is almost always a risk when we begin to transact or communicate online. When there is no protection, this risk may even increase. Therefore, the computer's Internet account and files are protected from any invasion, with the use of Internet security. Through passwords, changing file permissions, and backing up of computer's data is how Internet security works well.
Internet security is essential especially in the use of IT systems, where business owners feel safe and confident from any cyber criminal attacks. These attacks can be used for the hacker's profit. It is therefore imperative for businesses to be alert from any of these attacks that they may encounter.
Internet security should be articulate in four major aspects before it can be efficient and effective. These aspects are penetration testing, intrusion detection, incidence response and legally compliant with the law. Malicious intent can be hidden in several useful programs. A list below contains some of these useful programs.
Viruses. These are programs that can multiply their own structure or effect by attaching itself to files or structures that already exist in a penetrated computer. Furthermore, it threatens or alters the actions and the data stored without permission such as removing or corrupting information from the owner through a malicious and humorous payload.
Trojan horse or Trojan. These are programs that steal or change data and causing difficult problems on the computer or other programmable system or device while pretending to be innocent. Worms. These are programs that reproduce on an extensive basis such as in computer networks. Additionally, it can also perform malicious activities that in the long term can affect and cause detrimental effects in the whole system.
Spyware. These are programs that are secretly on the lookout on every keystroke or action the user does in the system of the computer and sends a report about these activities to others without authorization. Bots. These are programs that utilize the resources of the computer system by taking over it in a network without permission. Thus, it transmits information to those who control it.
All of these malicious software are generally called Malware. Malware usually damages or invades a computer program or any other programmable tool and system like home or office computer systems, networks, mobile phones, PDAs, automated devices, robots and any other sufficiently complex devices.
The different concepts above can together be combined or overlapped. This implies that not only do terminologies change; the hazards themselves are dynamic and constantly evolving.
Antivirus and Internet security programs are basically utilized to protect the computer or any other programmable device or system from any malware. These programs are commonly used to destroy viruses.
However, extreme caution should be done when purchasing antivirus software especially through downloads from the Internet because not all programs are as effective compared to others in terms of finding and eradicating malware such as viruses. Moreover, buyers should be vigilant since some websites may actually be trying to install malware into your computer.
