Aiempi tietoturvak\u00e4ytt\u00e4ytymisen tutkimus on keskittynyt suurelta osin kyselytutkimuksiin, joilla on selvitetty k\u00e4ytt\u00e4ytymisen aietta.

Viestin l\u00e4hetys toistettiin yhteens\u00e4 kolme kertaa ja viestien vaikutusta todelliseen lukitsemisk\u00e4ytt\u00e4ytymiseen havainnoitiin yhteens\u00e4 noin vuoden ajan. \n\nViestien sis\u00e4ll\u00f6n vaikutusta tutkittiin viestej\u00e4 manipuloimalla. Kirjallisuuskatsauksen perusteella viestien pohjaksi valittiin kaksi eri teoriaa: suojelumotivaatioteoria sek\u00e4 prospektiteorian mukainen viitekehyksen vaikutus. Suojelumotivaatioteoriaan perustuvia viestej\u00e4 manipuloimalla pyrittiin vaikuttamaan uhka-arvioon ja selviytymisarvioon. Viitekehyksen huomioivissa viesteiss\u00e4 k\u00e4ytettiin negatiivista ja positiivista kehyst\u00e4mist\u00e4.

Locking the workstation is a crucially important security measure that the user is responsible for. Neglecting this could result in unauthorized access to the information systems by a 3rd party. Previous research on information security behavior has focused mainly on survey studies that have used behavioral intention as the dependent variable. Studies observing actual behavior in a real organizational context have received significantly less attention. In this experiment an email message was sent to the staff of an organization in attempt to increase the locking of workstations. The intervention was repeated three times in total and the actual behavior was observed for a period of one year. \n\nThe effect of message content was studied by manipulating the messages according to two different theories. The theories used in this study were Protection Motivation Theory (PMT) and Prospect Theory based message framing effect. Regarding PMT, the aim was to affect the cognitive threat appraisal and coping appraisal processes. With message framing both positive and negative framing was used. In addition, personal relevance of the threat and the amount of details included in the messages were manipulated. \n\nThe interventions had a positive effect on the locking of workstations. The first two interventions increased the amount of daily locks by approximately 30 % combined. A small but positive change was observed for the third intervention. The relative daily amount of sessions with no lock events decreased by 40 percent. \n\nMultiple linear regression and average marginal effects were used to study the relationship between the manipulations made to the messages and the observed change in the locking of workstations in the first intervention. Messages that were based on framing effect were found more effective than messages based on PMT. Emphasizing the threat was effective on users who locked workstations more than an average user, whereas affecting the coping appraisal was effective on users who locked workstations less. Positive message framing was more effective than negative message framing. Emphasizing the personal relevance increased the effect of the intervention on those who locked workstations less than an average user. Manipulating the amount of detail did not have a noticeable effect.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2018-08-29T07:16:35Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2018-08-29T07:16:36Z (GMT).
