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.

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?

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.)
