在第一堂上完少林學長的課以後,對於社交工程比較有興趣,因為我覺得社交工程是我們平常生活中比較常遇到的,在還沒有上這堂課以前,我常常會因為好奇心而去點擊廣告之類的,科能自己殿寶已經有問題了自己都不知道,上完之後,我以後對於一些比較奇怪的東西會特別留意,以下是我去查關於社交工程的資料,雖然不能完全防範,但是至少對於我日後可以提高一些警覺心。

  • 什麼是社交工程?

社交工程是利用人性的弱點進行詐騙,是一種非「全面」技術性的資訊安全攻擊方式,藉由人際關係的互動進行犯罪行為,而他的手法有成千上萬種,技術門檻也較低,因此最難預防的就是社交工程的攻擊,但也是最簡單有效的方式。像是假冒Email的附件檔案、造訪特定網站、下載軟體,在點擊的時候食入惡意程式,來竊取資料。

  • 關於人性的弱點?
  1. 滿足人們的好奇心:對於一些聳動誇張的新聞標題
  2. 樂心助人的天性:對於一些需要幫忙轉發的新聞或是信件
  3. 太過於相信別人:太相信寄給你信的人,但其實他寄的是有問題的信件
  4. 貪心:利用人們貪小便宜的心態,吸引人去點一些優惠卷之類的
  • 社交工程的攻擊手法?
  1. 電子郵件詐騙:利用廣告郵件、釣魚郵件、病毒信件等等,誇張的標題或是熱門的新聞標題,來吸引人們去點擊,因此可以植入惡意程式。

     

 

2. 網路釣魚:利用偽造的網址或彈出的視窗,來誘騙人們洩漏機密資訊,例如銀行信用卡與帳戶資料。

3.圖片內含惡意程式(steganography:圖像隱碼術):

下載圖片時,他的影像檔末端其實有多出一些資料,而這些資料經過加解密之後,就會變成一個設定檔。因此導致系統出現漏洞,讓駭客有機會可以對電腦命令下載病毒並執行。

  • 如何防範?
  1. 「防人之心不可無」,隨時具備危機意識,對於任何詢問重要資料的人士,都需小心求證,應該要分帳號跟密碼的權限,防止資料外洩。
  2. 設定個人防火牆,定期更新病毒碼。
  3. 設定密碼時,應避免簡單易遭破解的英數文字,重要的資料要加密防護。
  4. 郵件的讀取要關閉預覽,改成純文字閱讀模式,確認信件的來源,避免開起郵件內的可疑的網址或附檔

There has to be a way to remove denim dye from light-colored leather longchamp outlet bags, right? Like, that can't be beyond the scope of chemistry. It's almost The Year of Our Lord 2017. It's been nearly a half century since we put a literal man on the moon. Can the field of textile research not spare a mind or two for this? No matter what the structure of the fendi outlet bag I'm carrying, I end up using the optional long shoulder strap most designs now have almost exclusively. They're used frequently by most people, which is why it's more or less mandatory that bags now have them. These shoulder straps aren't all created equal, though. In some cases, the shape of the bag and the potential interference of its other design features were taken into account when deciding the length, thickness and attachment points for the long strap, but in many cases, all those concerns were clearly ignored and some scrap leather was thrown on there so awkwardly and non-functionally that it almost feels like an act of aggression. For example, in 2017, here's hoping chanel outlet deigns to put a long enough shoulder strap on the Antigona that its top handles aren't constantly stabbing you in the armpit when you use it.
