Securing Logs of a System - An IoTA Tangle Use Case

Outbreak of the Internet and technological dependence make the Cyber Technology Industry grow at a very fast pace. Cyber-security is the dire need of today which helps prevent or defend the systems from cyber-attacks. Distributed Ledger Technology like Blockchain with its various properties and advantages opens many opportunities for its use in the cyber-security domain and mitigating the associated risks. These technologies remove the need of any central trusted party or authority, which would facilitate recording and tracking of resources. This paper focuses on the use of Distributed Ledger Technology (DLT) in the field of Cyber-security. It focuses on the discussion of new distributed ledger technology IOTA, its features and working. This paper also focuses on one of the uses of the IOTA Tangle technology, which provides a solution for securing logs of a system. As the logs of a system are the most important evidence in the investigation phase of Cyber-Forensics, thus preserving the logs securely and maintaining their integrity is mandatory. Later in this paper, the use of IOTA is demonstrated for securing the logs of a system.
