Course Overview
- Embark on a practical, hands-on expedition into mobile network security, from the foundational GSM to the advanced 5G. This course meticulously dissects the operational mechanics, underlying protocols, and, crucially, the inherent security vulnerabilities across these pervasive networks.
- Moving beyond abstract theory, ‘Wireless Networks & SDR’ leverages Software Defined Radio (SDR) principles for direct, actionable application. You will gain the ability to intercept, analyze, and even simulate various network interactions, providing an unparalleled understanding of their real-world behavior.
- A significant focus is placed on understanding the SS7 signaling protocol, a critical backbone for legacy networks, uncovering its persistent security weaknesses and their modern implications across the mobile ecosystem.
- Through a series of practical “hacks” and demonstrations, you will gain unparalleled insights into how mobile networks can be exploited and, more importantly, how to formulate robust defensive strategies against such threats.
- This accelerated 5.5-hour program is your direct gateway to mastering practical mobile network security and reverse engineering, bridging theoretical knowledge with tangible, real-world application using industry-standard tools like HackRF and GNU Radio.
- Understand the evolution of mobile communications, from 2G’s core functionalities and weaknesses to the complexities and emerging security landscapes of LTE and 5G.
Requirements / Prerequisites
- A foundational understanding of computer networking concepts (e.g., IP addressing, TCP/IP stack) is beneficial, though not strictly mandatory for all course modules.
- Basic familiarity with the Linux command line interface (CLI) is strongly recommended, as many of the tools and lab environments utilized are Linux-based.
- An eager and inquisitive mind, coupled with a keen interest in wireless communications, cybersecurity, and practical experimentation, is absolutely essential.
- Hardware: While viewing the course content is flexible, active participation in the practical “hacks” and SDR exercises will necessitate access to specific hardware.
- Strongly Recommended Hardware for Practical Labs: A HackRF One or a similar full-duplex Software Defined Radio device is crucial for engaging effectively with the hands-on SDR segments and replicating demonstrations.
- Software: Virtualization software such as Oracle VirtualBox or VMware Workstation/Player is recommended for setting up isolated lab environments. Installation of GNU Radio Companion and its associated libraries will be either covered within the course or assumed for practical modules.
- No prior expertise in Software Defined Radio or advanced mobile network protocols is strictly required; the course is designed to build knowledge from foundational concepts.
