Network security and secure communication
Date: 3 June 2025
Time: 9:00 to 13:30 CEST
Implementing a secure networked application can be challenging, even for developers who are familiar with cryptographic building blocks like encryption and digital signatures. This course provides participants with a comprehensive understanding of the role and usage of cryptographic primitives, focusing on their application in secure communication.
The training begins by establishing a solid foundation in the main requirements of secure communication, including secure acknowledgement, integrity, confidentiality, remote identification and anonymity. Typical problems that compromise these requirements are highlighted, along with real-world solutions.
Since cryptography is a critical aspect of network security, the course covers the most important cryptographic algorithms in symmetric cryptography, hashing, asymmetric cryptography and key agreement. These elements are discussed from a developer’s perspective, showcasing use-case examples and practical considerations related to the usage of crypto, such as public key infrastructures.
Participants will also explore security protocols across different domains of secure communication, with a detailed focus on widely-used protocol families such as IPSEC and SSL/TLS. Additionally, the course addresses XML technology, which is central to data exchange in networked applications. Topics include the security aspects of XML in web services and SOAP messages, along with protection measures such as XML signature and XML encryption. Vulnerabilities specific to XML—such as XML injection, XML external entity (XXE) attacks, XML bombs, and XPath injection—are thoroughly discussed.
