Google Analytics 是一个网站流量统计程式。我觉得对于一般人来说，Analytics 的功能太多了，里面有一些名词也不是很好懂，导致进到 Analytics 网站后很难找到想要查看的资料!
本网页的教学要带你查看 Analytics 里记录的“Referral”资料，这 Referral 资料可以让我们了解访客是从哪个网站转介到我们的网站。

Visual Studio Code 的安装说明，以及推荐的延伸模组 (Windows/Linux)
微软开发的 Visual Studio Code (简称 VS Code) 是一套非常热门的“编辑器”! VS Code 跨平台，且开放原始码。它虽然仅是一个轻量版的编辑器，却可经由安装延伸模组来支援程式码语法突显、侦错、自动补全、重构、Markdown...等琳瑯满目功能，打造你梦想中的 IDE (整合开发环境)。
VS Code 默认仅支援 JavaScript、TypeScript、CSS、HTML，同样能透过下载延伸模组来支援 Python、C/C++、Java、Perl、Go... 等其他程式语言。
[Perl]如何在 Visual Studio Code 建立 Perl 的程式开发环境 (Windows/Linux)
据说 Perl 可能是近几年会消失的 5 种程式语言之一 (另外 4 个语言分别是 Ruby、Haskell、Object-C 跟 R)! 现在在 Visual Studio Code (简称 VS Code) 建立 Perl 的程式开发环境也算是帮 Perl 续一下命，大慈大悲、功德无量。
要建立好整个 Perl 的开发环境主要分为三个步骤:
- 安装 Perl 的执行环境
- 安装 VS Code Editor
- 在 VS Code 安装 Perl 的延伸模组 (Extension)
如何解决 TLS/SSL 使用了不安全的加密算法: ARCFOUR、CBC、HMAC-MD5、HMAC-RIPEMD160
弱点扫瞄
弱点: TLS Service Supports Weak Cipher Suite
Transport Layer Security (TLS), the successor to Secure Socket Layer (SSL), is a network protocol that encrypt communications between TLS servers (e.g., websites) and TLS clients (e.g., web browsers). Every communication is secured by a cipher suite: a combination of several algorithms working in concert. Cryptographic algorithms do not have a defined lifetime, but academics, researchers, and nation states are constantly evaluating them for weaknesses. Consensus on which algorithms are untrustworthy evolves over time, and if a communication is protected with a weak cipher suite then that communication can be altered or decrypted.
- Severity: Medium
- Risk: A TLS service was observed supporting weak cipher suites.
- Recommendation: Disable the cipher suites listed in the evidence column of the measurement.
如何解决 SSH Server 使用了不安全的加密算法: ARCFOUR、CBC、HMAC-MD5、HMAC-RIPEMD160
弱点扫瞄
弱点 1: SSH Supports Weak Cipher
The SSH server is configured to support either Arcfour or Cipher Block Chaining (CBC) mode cipher algorithms. SSH can be configured to use Counter (CTR) mode encryption instead of CBC. The use of Arcfour algorithms should be disabled.
- Severity: Medium
- Risk: A weak cipher has been detected.
- Recommendation: Configure the SSH server to disable Arcfour and CBC ciphers.
弱点 2: SSH Supports Weak MAC
The SSH server is configured to support MD5 algorithm. The cryptographic strength depends upon the size of the key and algorithm that is used. A Modern MAC algorithms such as SHA1 or SHA2 should be used instead.
- Severity: Medium
- Risk: A weak Message Authentication Code (MAC) algorithm has been detected.
- Recommendation: Configure the SSH server to disable the use of MD5.
