Explore the fundamentals of semantic web technologies and ontology development in this 51-minute conference talk from BSidesLV 2014. Delve into the history of the Semantic Web, learn about triples as the basic building blocks of semantic data, and understand the key elements of ontology creation. Discover how to define "things," identify nodes, and work with literals and predicates. Gain insights into writing schemas, using the Web Ontology Language (OWL), and building ontologies. Examine the relevance of semantic technologies to information security, including applications to the Cyber Kill Chain. Investigate triple stores, SPARQL queries, and the current state of security ontologies and tools. Conclude by exploring ways to harness tribal knowledge in the field of cybersecurity through semantic technologies.
