解答
意味：英辞郎によると、
《a ～》《コ》〔パスワードや暗号を破るための〕総当たり攻撃Brute forceとは、「暴力、ばか力、力ずく」。したがって、brute force attackを直訳すれば、「力ずく攻撃」ということになります。また、問題の見出しにあるdictionary attackは、brute force attackのひとつで、辞書にある全ての単語を使用することからこのような名称になりました。
下記英語の定義を参照してください。
なお、英辞郎ではhyphenを入れてますが、実際の記事等を見るとほとんど使用してません。
Answer
According to Technopedia:A brute force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). In a brute force attack, automated software is used to generate a large number of consecutive guesses as to the value of the desired data.One example of a type of brute force attack is known as a dictionary attack, which might try all the words in a dictionary. Other forms of brute force attack might try commonly-used passwords or combinations of letters and numbers.
An attack of this nature can be time- and resource-consuming. Hence the name "brute force attack;" success is usually based on computing power and the number of combinations tried rather than an ingenious algorithm.
Examples
- A brute force attack, also known as an exhaustive search, is a cryptographic hack that relies on guessing possible combinations of a targeted password until the correct password is discovered.
- In this post, we explore brute force attacks in more detail, including some examples, and then reveal how you can protect against them.
- Brute force attacks are often referred to as brute force cracking. Indeed, brute force — in this case computational power — is used to try to crack a code.
- Brute-force attacks can also be used to discover hidden pages and content in a web application.
