How to safeguard our personal& financial data?

How safe is our data? Do you know how to protect your data? For me, I only know the basic way to protect my data. Nowadays, my way to protect data is outdated, because there is a lot of software that can easily hack into my data or computer. Hacker is the “most professional people” that steal the data; they can easily steal data without your knowledge. As this is very dangerous for the innocence people, that is you and me, because we don’t know have strong knowledge in protecting our data. In order to adapt to current situation, we need to start to protect our data now.

There are some ways to safeguard our data:
1) Set up password
Setting up password is the most basic way to protect data, but the others can still steal your data if your password can be guessed. We avoid using password such as birthday, name and identity card number, this type of password is can be easily guessed by other people. Besides that, we should not use repeating word in a password e.g. Betty. The length of the password is also very important, we need to set password that is at least 7 words long. Nowadays, when setting up the password there will be an identification of the strengtheners of your password. Remember to set the password that is strong enough to avoid stealing of data. 2) Firewall
A firewall is a part of a computer system or network that is designed to block unauthorized access. Firewalls are usually used to prevent unauthorized users from accessing private networks, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that are unauthorized. Firewall is suitable for individual or organization use. There is a lot of firewall software that are available in the internet; you can download it for free. 3) Antivirus Software
A computer virus is a computer program that can copy itself and infect a computer without the permission of the owner. Virus can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer. In order to avoid virus hacking our computer, we need to install antivirus software. The software must be very strong enough to “kill” the virus. Besides that, we need to update antivirus software everyday, so there will be strong protection for our data. 4) Log in, log out
When you log in to some website, the website may keep your username and password. This may be dangerous when you using public device to log on to that website. Others may steal your data without your knowledge. So, when you log in to one website, you need to make sure that you have clear the data. This will ensure that your data will not be hack by others. Besides that, when you sign in to one account, you need to ensure that you have sign out from that account, because some people will directly close the window and they think that the account will be automatically sign out. Some website will automatically sign out your account but not all. You need to make sure that you have signed out to the account and make a double check by log in another time to that website.
