These include both quantitative and qualitative methods. We show here how quantitative methods, such as timeline, local averages and exponentially weighted moving average analyses, led in this work to the discovery of three anomalies in a large open DNS dataset published by the Los Alamos National Laboratory.<\/jats:p>","DOI":"10.7287\/peerj.preprints.27116v1","type":"posted-content","created":{"date-parts":[[2018,8,14]],"date-time":"2018-08-14T16:23:32Z","timestamp":1534263812000},"source":"Crossref","is-referenced-by-count":0,"title":["Anomaly analysis on an open DNS dataset"],"prefix":"10.7287","author":[{"given":"Benjamin","family":"Aziz","sequence":"first","affiliation":[{"name":"School of Computing, University of Portsmouth, Portsmouth, United Kingdom"}]},{"given":"Nikolaos","family":"Menychtas","sequence":"additional","affiliation":[{"name":"Zananet, Southampton, United Kingdom"}]},{"given":"Ammar","family":"Al-Bazi","sequence":"additional","affiliation":[{"name":"Coventry University, Coventry, United Kingdom"}]}],"member":"4443","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/peerj.com\/preprints\/27116v1.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/peerj.com\/preprints\/27116v1.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/peerj.com\/preprints\/27116v1.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/peerj.com\/preprints\/27116v1.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T19:32:30Z","timestamp":1577129550000},"score":1,"resource":{"primary":{"URL":"https:\/\/peerj.com\/preprints\/27116v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,8,14]]},"references-count":0,"aliases":["10.7287\/peerj.preprints.27116"],"URL":"https:\/\/doi.org\/10.7287\/peerj.preprints.27116v1","relation":{},"subject":[],"published":{"date-parts":[[2018,8,14]]},"subtype":"preprint"}}
