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:
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.
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. 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
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. 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.
Ways to protect eyes from screens
Too much screen time may cause serious eye strain(眼疲劳) and even a sharp decline of eyesight. That's a big problem a lot of people are faced with nowadays, especially those who work on a computer. The following tips may be helpful.
Get regular eye tests.
Experts recommend having a comprehensive eye exam every year to detect (探测) problems before they develop. During this test, you should tell the doctor how often you use your phone and your computer. {#blank#}1{#/blank#}Tell your doctor about it, and your eyes can be tested more accurately at that distance.
Give your eyes space
{#blank#}2{#/blank#} Studies on computer-related eye strain suggest that screens should be no closer than 40cm from your face. If this makes it hard for you to read, consider increasing the size of the text rather than moving the screen closer.
Take breaks
This may not always be practical if you're quite busy, but it's important not to stare directly at a screen for too long. {#blank#}3{#/blank#} While surveys have shown that many office workers take no more than half an hour a day away from their computer, it's recommended that you take a 15-minute break after every two hours spent at your screen.

Staring at a screen continuously for hours on end may make it difficult for you to focus. To avoid this, many eye experts recommend the “20-20-20 rule” --looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds. The science behind his trick is that looking at objects at a distance relaxes the focusing muscle in the eye. {#blank#}5{#/blank#}.
A. Exercise your eyes. B. Give your eyes a chance to rest. C. Make your screen more eye-friendly D. Studies show it's an effective way to reduce tiredness. E. You should also measure the distance from your eyes to your screen at work. F. The closer your phone/computer screen is to your eyes, the harder they have to work to focus. G. Make sure that you use your phone or computer in a room where the lighting is bright enough. |
