就千維網部分博文消失事件答記者問(下) 在上期中本報特約記者令狐沖採訪了天朝有關部門負責人,副局級科員全庸筒子。據全筒子跟中共駐千維特委的負責筒子了解,千維網發生的部分網友博文消失事件,跟我後清朝廷無關。 據了解,天朝有關部門有十幾個,除了全庸筒子外,還有朱堅強等筒子正在度假治療,不接受採訪。疑似跟事件有關的茅十八,小安安等以迅雷不及掩耳盜鈴之勢消失。 本小記娛記出身,雖然擅長編排花邊新聞,但對這麼重大的惡性事件,雖經高人指點,還是一頭霧水。尤其是,在事件發生後,眾多嫌疑人以迅雷不及掩耳盜鈴之勢消失,令事件真相更加難以發掘。 無奈之下,本記者採取第二套方案,採訪了一個網絡安全家族。這個家族的成員除了大哥歡樂頌以外,都是ABC。包括芒果頌,菠蘿頌,香蕉頌,枇杷頌,荔枝頌,龍眼頌等人,雖然能聽一些中文,但說不好,因此對本記者的回答多以英文進行。 令狐:請問,什麼樣的密碼才能成為安全的密碼。 芒果頌: The strength of a password is a function of length, complexity, and unpredictability. 令狐:明白了,一個好的密碼要考慮長度,複雜性和不可預測性。那麼這三者中那一個更重要? 香蕉頌:Length does matter, le me tell you a story. 香蕉頌: A new employee joins the Company, and is required to have a password setup for his computer. The boss directed a secretary to setup the password for him. The secretary asks the man for the password. The man, attempting to embarrass the secretary in order to show superiority, said, "Penis." Blushed, the secretary inputted the password Penis, and re-typed it again. Then she hit enter. The whole office heard the secretary bursting out of laughter's as a reaction from the computer's screen: "Password rejected. Reason: Too short" 令狐:哈哈哈,看來長度的確是很重要,不夠長就通不過啊。 香蕉頌: 夜視,There are two factors to consider in determining password strength: the average number of guesses the attacker must test to find the correct password and the ease with which an attacker can check the validity of each guessed password. The first factor is determined by how long the password is, how large a set of characters or symbols it is drawn from and whether the password is created randomly or by a more predictable process... 令狐:明白了。判斷密碼強度要從三個方面考慮,即其長度,複雜性和不可預測性。一個強密碼要有足夠的長度,並隨機排列,這樣潛在的進入者就需要花很多時間才能夠破譯。 令狐:跟洋鬼子說話真累。總之,各位看官切記,密碼要加強,長度要達到8位以上。除此之外,還要記得備份。關於備份,頌家族的大哥歡樂頌曾經傳授過一個很實用的備份工具--ScrapBook for Firefox。 如何“一鍵”備份全部博客文章 令狐: 以下是菠蘿頌,荔枝頌的兩個視頻,和一些文章供各位參考。 http://zh.wikipedia.org/wiki/%E5%AF%86%E7%A0%81%E5%BC%BA%E5%BA%A6 http://en.wikipedia.org/wiki/Password_strength http://www.microsoft.com/security/online-privacy/passwords-create.aspx http://blogs.mcafee.com/mcafee-labs/password-policy-length-vs-complexity
