A working security education in Fifth Generation (5G) mobile network architecture, for readers who need to understand how it changes the network security model rather than only how it changes network speed. You will learn why disaggregation and network function virtualization expand the attack surface compared to earlier, hardware centric generations, why network slicing is fundamentally a multi tenant isolation problem, why the expanded edge computing surface multiplies the number of locations requiring security attention, the supply chain and regulatory review considerations specific to 5G equipment, and the genuine authentication and encryption improvements 5G delivers alongside the areas where research attention continues. The closing lesson is explicit that specific current standards and regulatory requirements must be verified against current guidance for your own jurisdiction and deployment.
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.
