Network security is concerned with hardware, software, basic communication protocols, network frame structure, and communication mechanisms factors of the network. Information Security in the network context deals with data integrity, confidentiality, availability and non-repudiation while is sent across the network. A distributed system is a model in which components located on networked computers communicate and coordinate their actions by passing messages. In this context cybersecurity deals with all the aspects of computation, coordination, message integrity, availability and (if required) confidentiality. Message authentication is also in the scope.
The subdomains for this knowledge domain are:
- Network security (principles, methods, protocols, algorithms and technologies)
- Distributed systems security
- Managerial, procedural and technical aspects of network security
- Requirements for network security
- Secure system interconnection
- Protocols and frameworks for secure distributed computing
- Network layer attacks and mitigation techniques
- Network attack propagation analysis
- Distributed systems security analysis and simulation
- Distributed consensus techniques
- Fault tolerant models
- Secure distributed computations
- Network interoperability
- Network steganography
- Privacy-friendly communication architectures and services (e.g. Mix-networks, broadcast protocols, and anonymous communication)
