The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web(WWW).
Internet Security is something that has grown to be a main concern among society. Companies have come out with Identity Theft prevention services, but often, by the time you get those, it is already too late or doesn’t help.
Many of you probably hear on the news, every so often, “A popular website has been compromised and many people have had their personal data stolen!” When a website is compromised, it puts thousands at risk for one of many possible types of identity theft. It is rare that a site is hacked to this extent: usually, the data is collected through look alike sites, through spyware, or through other means of collection; most of which happen on a single-user basis. It makes many people nervous when giving out personal information to anyone online because they are not sure what can really happen, and they do not have all the facts.
Internet Threats
There are few type of internet threat that appear in the internet, let us go through three of the most popular threat:
(i)VirusVirus is a Malicious software that attaches itself to other software. For example, a patched software application in which the patch's algorithm is designed to implement the same patch on other applications, thereby replicating. It replicates within computer system, potentially attaching itself to every software application.
Below is the behaviour that virus has:
Behavior categories:
-Innocuous
-Humorous
-Data altering
-Catastrophir

(ii)WormIt's a malicious software which is a stand alone application. It's often designed to propagate through a network, rather than just a single computer. When your computer is infect of worm, computer will slow starting or slow running. It'll also face unexpected or frequent system failures.
(iii)Trojan HorseIt is a Worm which pretends to be a useful program or a Virus which is purposely attached to a useful program prior to distribution. It's same as Virus or Worm, but also sometimes used to send information back to or make information available to perpetrator. Trojan unlike Worms, which self propagate, it's require user cooperation.
Those internet security threat will try to steal your information from your computer through the internet. It's very danger if our computer online without any internet security system such as anti-virus. For example, Trojans will track into your computer and steal your personel information such as password of your e-banking account, email account and etc. For business companies, it's really a treat to them because they save their business infromation in the computer such as daily profits, project or new planning for their business venture. But there are still some prevention that we can do to prevent internet threat.
Below are the ways to prevent internet threat:
- Limit connectivity. Limit downloads
- Use only authorized media for loading data and software
- Enforce mandatory access controls.
- Viruses generally cannot run unless host application is running
- Always remember to scan your computor with Anti-virus
- Delete all the cookies in the computor to prevent track on the history/password.
- On your firewall to prevent hackers.
As conclusion, internet has the advantages and disvantages. If we prepare well before we online, surely we'll be secure and safe from internet threat.
