How to Protect Yourself from Hackers Online

An increase in cyber-attacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyber-attacks:

1.

Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.

Change your password regularly

A very common mistake made by users is to create one hard password, but then never change it. Remembering a long list of complicated passwords can be difficult. But no password is unbreakable. Hackers are better able to hack multiple accounts if those accounts all have the same password. A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords. 2.

Clear your browser (浏览器) history

This goes for all the devices you use in a day – your home computer, your work computer, or your friend's iPad. Internet browsers like Firefox or Chrome keep track of where you've been and what you've done online. They keep records of every site you visited. 3. It is very easy for anyone who sees that information to steal a detailed record of your online activities.

Do not use free Wi-Fi

4. Often, a user does not need a password to connect to these wireless networks. These services might be useful, but they're also an easy way for hackers to access everything on your device.

Use anti-virus protection

There are many anti-virus services available for users. 5. Some anti-virus services are even free. They are a great way to have a professional help keeping users one step ahead of hackers.

A. Be careful while using thumb drive.

B. These services permit users to easily store and secure their passwords.

C. Make your password harder to hack.

D. They can offer many different types of computer protection.

E. An increasing number of public places now offer free wireless access to the Internet.

F. Information about what you sent from or saved on your computer can be kept for days or weeks.

G. Unless you really need it, it is best not to use it.
