Telecommunication is the foundation on which critical infrastructures are built – all modern technologies heavily rely on its security. The continued adoption of IP-based telecommunication and the exposure of telecom equipment opens additional paths for attackers, with a massive increase in security incidents against telecom systems.

The security of customer premises equipment and the prevalence of Internet of Things (IoT) devices is especially critical, as these devices are directly exposed to attackers and potentially resulting in large-scale attacks against users and companies alike. IoT security is recognized by the industry as a critical area of telecommunications, as evidenced by the efforts of the GSM Alliance to produce a set of IoT security guidelines for network operators.

The threats against telecom systems run the gamut from simple-yet-effective DDoS attacks to large-scale exploitation of vulnerabilities in communication equipment. Ultimately, the best way to deal with these challenges, you need motivated secure coders with the right skills and the right attitude to fight security problems: a skilled team of software and network engineers.

This training program exclusively targets engineers developing software applications or network equipment for the healthcare sector. Our dedicated trainers share their experience and expertise through hands-on labs, and give real-life case studies from the telecom industry – engaging participants in hands-on labs to realize the harsh consequences of insecure coding.
