1 CISC 849 : Applications in Fintech Vaishnavi Gandra Dept of Computer & Information Sciences University of Delaware Extracting Cybersecurity Related Linked Data from Text

2 CISC 849 : Applications in Fintech Cybersecurity For the protection of personal data from cyber crime. Security standards in an organization. Information security What is cyber crime?

3 CISC 849 : Applications in Fintech Detection of cyber crime Threat: A possible danger that might exploit vulnerability Vulnerability: Weakness in a system which allow the attacker to attack a system Internet in cyber world Framework for extracting the information

4 CISC 849 : Applications in Fintech National Vulnerability Database CVE CWE Product Dictionary datasets Patch information Vendor releases

5 CISC 849 : Applications in Fintech Data collaboration Zero day attack Extracting the unstructured data RDF linked open data NVD Process

6 CISC 849 : Applications in Fintech Information extraction: o Converting the unstructured form of text o Introduced the concept of Spotter Linked Data: o Why do we need linked data? o Why is RDF helpful? Approach to extract linked data

7 CISC 849 : Applications in Fintech Concept Spotter RDF Link generator Architecture

8 CISC 849 : Applications in Fintech Identifies relevant concept from text Software Network terms: IP address Attack: Means and Consequences File name Hardware NER Modifier Concept Spotter

9 CISC 849 : Applications in Fintech What is RDF? How are the RDF triples formed? RDF

10 CISC 849 : Applications in Fintech How data link is formed? Data link is stored in Dbpedia Concept Spotter: NVD data is passed through the concept spotter and returns Linked data

11 CISC 849 : Applications in Fintech Intrusion Detection System

12 CISC 849 : Applications in Fintech IDS Vulnerability: NVD, CVE Product: Specifies the area that is affected by vulnerability Weakness: CVE identifier is derived

13 CISC 849 : Applications in Fintech Usage of NVD for extracting data

14 CISC 849 : Applications in Fintech Description of NVD Unavailable resources Complexity of mapping between databases Challenges faced

15 CISC 849 : Applications in Fintech Example

16 CISC 849 : Applications in Fintech What’s next? Unidentified data Enhancing existing framework Creating situation awareness
