A defensive, pattern-focused course on insecure deserialization: what makes reconstructing an object from an untrusted stream dangerous, why it bypasses normal input validation, and the full impact spectrum from data corruption up to remote code execution. You will learn where this pattern hides across languages, carriers and code review practice, apply a priority-ordered mitigation hierarchy, understand why generic filters like a Web Application Firewall (WAF) cannot substitute for call-site controls, and build a remediation program that reaches internal services as thoroughly as external ones, all without ever constructing an exploit.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.
The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.
