Translate the following passage from English into Chinese:Intruder (入侵者) attacks range from the benign (良性的，溫和的) to the serious. At the begin end of the scale, there are many people who simply wish to explore internets and see what is out there. At the serious end are individuals who are attempting to read privileged data, perform unauthorized modifications to data, or disrupt the system.The objective of the intruder is to gain access to a system or to increase the range of privileges accessible on a system. Most initial attacks use system or software vulnerabilities that allow a user to execute code that opens a back door into the system. Intruders can get access to a system by exploiting attacks such as buffer overflows (緩存溢出) on a program that runs with certain privileges.Alternatively, the intruder attempts to acquire information that should have been protected. In some cases, this information is in the form of a user password. With knowledge of some other users’ password, an intruder can log in to a system and exercise all the privileges accorded to the legitimate user.入侵者攻擊從溫和的到嚴(yán)重的形形色色。在這一系列攻擊的溫和端，有許多人只是希望探查互聯(lián)網(wǎng)，看看那里有什么。在嚴(yán)重端的是試圖閱讀特許數(shù)據(jù)、對(duì)數(shù)據(jù)進(jìn)行未經(jīng)授權(quán)的修改或擾亂系統(tǒng)的個(gè)人。入侵者的目標(biāo)是獲得進(jìn)入一個(gè)系統(tǒng)的機(jī)會(huì)，或者增加在一個(gè)系統(tǒng)中可以使用的特權(quán)范圍。初始攻擊大多利用系統(tǒng)或軟件的脆弱之處，這些脆弱之處允許用戶執(zhí)行相應(yīng)的代碼，打開進(jìn)入系統(tǒng)的后門。入侵者可對(duì)具有某些運(yùn)行特權(quán)的程序?qū)嵤┫窬彺嬉绯鲞@樣的攻擊，利用此類攻擊獲得進(jìn)入一個(gè)系統(tǒng)的機(jī)會(huì)。另外，入侵者也試圖獲取應(yīng)予保護(hù)的信息。在有些情況下，這種信息是以用戶口令的形式存在的。知道了某個(gè)其他用戶的口令之后，入侵者就可以登錄系統(tǒng)并行使賦予合法用戶的所有特權(quán)。Unit Ten/Section BI.

Most mercial antivirus software uses both the virus dictionary approach and the suspicious behavior approach with emphasis on the virus dictionary approach.2. An emerging technique to deal with malware in general is whitelisting which prevents execution of all puter code except that which has been previously identified as trustworthy by the system administrator.3. Instead of attempting to identify known viruses, the suspicious behavior approach provides protection against brandnew viruses that do not yet exist in any virus dictionaries.4. Usually one should have only one type of memoryresident antivirus software installed on a single puter.II.
