The Threat of Online Security: How Safe is Our Data?

Online security means the prevention of unauthorized access and/or damage to the computer system through online access. So, our online systems should be protected by the online security. Nowadays, there has been improvement in the online securities because of the growth of the technology. However, there are still a lot of threats of online security.

The few examples of the online security threat are:
1) Viruses
Virus is a common cause of computer problems. Most of the virus spread through the online activities such as opening the unknown e-mail or sending through the online system. Some viruses rewrite coding to make software programs unusable, while others scramble or destroy our data. Many viruses spread quickly so they may not be noticed until the damage has already been done. So, our data will be damage or destroy.

2) Hackers
There are two main methods hackers can cause problems to computer systems and our data. They either find a way to enter the system and then change or steal information from the inside, or they attempt to over-whelm the system with information from the outside so that it shuts down. The hackers may enter to our network though an open port, or an Internet connection that remains open. Besides that, they also attempt to appropriate passwords that belong to the users. A lot of hackers are skilled at guessing common password and run programs that locate or capture password information.

3) Phishing
Phishing is one of the most damaging online security threats in recent times. Basically it involves an attempt by a fraudster, to extract confidential information from the innocent victim. Usually, the fraudster will create a clone site that look similar to the web page that the user will enter. For example, the web page of Public Bank e-banking. The fraudster will create a similar web page. Then, the users will access to their account. Once this happen, the fraudster will get the information and can access to the users account. So, the fraudster will illegally transfer the user's fund.
