Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

As computer use becomes more common, the need for security is more important than ever. One of the greatest security threats in the online world is computer hacking. Computer hacking is the unauthorized access to a computer or network of computers. Hackers are people who illegally enter systems. They may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things?

Most hackers use information called protocols that are built into computer software. These protocols allow computers to interact with one another. Protocols are sort of like computer police officers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate the protocols to get unlimited access to a computer system.

In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to access a challenging system like a bank or military network. Another kind of hacker tries to do damage to a system. After hacking into systems, these hackers release viruses or alter, delete, or take information. Known as active hackers, they are, by far, the more dangerous of the two.

        The easiest way to protect a system is with a good password, Long and unusual passwords are harder for hackers to guess. For even greater security, some online services now use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time. Even if a hacker steals the password, they won't have the code. Or if the hacker somehow gets the code, they still don't know the password.

As suggested in the last paragraph, what is the best way for computer users to prevent hackers?

A. They should use a long and customary password so that hackers cannot guess.

B. They should use different passwords for different accounts to access the sites.

C. They should have an additional secret code to confirm for their access after putting a password.

Đáp án chính xác

D. They should not use any code on online services to make sure that hackers have no chance to get your password.

Đáp án C

Như đã được gợi ý trong đoạn văn cuối, cách tốt nhất để người dùng máy tính ngăn chặn tin tặc là gì?

A. Họi nên sử dụng một mật khẩu dài và thông dụng để tin tặc không thể đoán.

B. Họ nên sử dụng các mật khẩu khác nhau cho các tài khoản khác nhau khi đăng nhập vào các trang mạng.

C. Họ nên có thêm một mã xác nhận bí mật để xác nhận cho quyền truy cập của họ sau khi đã nhập mật khẩu.

D. Họ không nên sử dụng bất kì một mã nào trên các dịch vụ trực tuyến để đảm bảo rằng tin tặc không có cơ hội đánh cắp mật khẩu.

(Cách đơn giản nhất để bảo vệ hệ thống là sử dụng 1 mật khẩu tốt. Mật khẩu đài và khác thường sẽ khiến tin tặc khó đoán được. Để bảo mật hơn nữa, một số địch vụ trực tuyến hiện nay đã sử dụng hệ thống “mật khẩu cộng mật khẩu”. Trong trường hợp này, trước hết người dùng nhập mật khẩu, sau đó nhập tiếp một mã thứ hai mà luôn thay đổi sau khi người dùng truy cập vào trang mạng. Người dùng sẽ có các dịch vụ hoặc thẻ đặc biệt cho họ biết mã truy cập mới cho lần đăng nhập tiếp theo. Ngay cả khi tin tặc lấy cắp được mật khẩu, họ cũng sẽ không có mã đăng nhập. Hoặc bằng cách nào đó tin tặc lấy được mã đăng nhập, họ cũng không thể biết mật khẩu là gì.)

CÂU HỎI HOT CÙNG CHỦ ĐỀ

Câu 1:

Read the following passage and mark the letter A, B, C, or II to indicate the answer to each of the question.

As Hurricane Florence zeroes in on the southeastern US, scientists are warning that climate change is exacerbating the effect of tropical storms. The powerful Category 4 Atlantic weather-front is slow moving, an increasingly common phenomenon that poses a different manner of threat to states in its path. In the event that Florence stalls or comes to a halt altogether over land, it has the potential to deposit catastrophic quantities of rainwater, posing a risk of severe flash flooding.

While the high winds and waves generated by faster storms moving inland from the ocean pose a significant danger to human life and property, the effect of heavy rain can be just as devastating, if not more so. When Hurricane Harvey hit in August 2017, it dropped 60 inches of rain over Houston, Texas, flooding the streets, leaving 93 dead and hundreds more having to be rescued by boat, causing millions of dollars-worth of damage.

James Kossin of the National Oceanic and Atmospheric Administration published a study in the journal Nature in June suggesting that slow-moving tropical cyclones, which would include those like Florence and Harvey, have become more common over the last 70 years, dropping in speed by 10 per cent in that time. According to Mr Kossin, global warming as a result of man-made air pollution is causing the poles to become warmer, which in turn reduces the difference in temperature between the Arctic and Antarctic and the equator, altering atmospheric pressure and slowing down the whipping currents of wind that pass between them and drive hurricanes.

In the 3rd paragraph, James Kossin suggests that ______.
