+<overview>
+<p>
+Using an insecure protocol like HTTP or FTP to download build dependencies makes the build process vulnerable to a 
+man-in-the-middle (MITM) attack.
+</p>
+<p>
+This can allow attackers to inject malicious code into the downloaded dependencies, and thereby 
+infect the build artifacts and execute arbitrary code on the machine building the artifacts.
+</p>
+
+</overview>
+<recommendation>
+
+<p>Always use a secure protocol, such as HTTPS or SFTP, when downloading artifacts from an URL.</p>
+
+</recommendation>
+
+<example>
+<p>
+The below example shows a <code>package.json</code> file that downloads a dependency using the insecure HTTP protocol.
+</p>
+<sample src="examples/bad-package.json" />
+<p>
+The fix is to change the protocol to HTTPS.
+</p>
+<sample src="examples/good-package.json" />
