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.
