Since all applications today heavily rely on communications and networks, there is no application security without network security.
This course focuses on network security with a software security viewpoint, and discusses common network attacks and defenses on different OSI layers, with an emphasis on application layer issues, tackling topics like session management or denial of service.
As cryptography is a critical aspect of network security, the most important cryptographic algorithms in symmetric cryptography, hashing, asymmetric cryptography, and key agreement are also discussed. Instead of presenting an in-depth mathematical and theoretical background, these elements are discussed from a merely practical, engineering perspective, showing typical use-case examples and practical considerations related to the use of crypto, such as public key infrastructures.
