Level: Intermediate | Genre: eLearning | Language: English + subtitle | Duration: 39m | Size: 113 MB

Stop risky file handling in Go. This course will teach you to validate uploads, scan content, and block SSRF/LFI so your Go services safely accept and process untrusted files and URLs.

Accepting files and URLs without defenses leads to malware, data exposure, and costly incidents. In this course, Data Input Validation for Go Applications, you’ll learn to implement robust validation for file and URL inputs in Go web apps. First, you’ll explore building a safe upload pipeline: size limits, content-type and magic-byte checks, safe filenames, and storage outside the web root. Next, you’ll discover how to scan uploads with ClamAV and enforce path isolation and permissions. Finally, you’ll learn how to defend against SSRF, remote file inclusion, and local file inclusion with strict allowlists and request controls. When you’re finished with this course, you’ll have the skills and knowledge of Go input validation needed to safely accept and process untrusted data in production.
