This study analyzes the technological and human aspects of phishing attacks through a literature review. The research aims to identify the factors that expose companies to phishing, the most effective technological solutions for combating such attacks, and the role of human factors, such as behavior and organizational culture, in vulnerability to phishing. The findings indicate that combating phishing requires a multidisciplinary approach. Technological solutions, such as machine learning-based email filtering systems and natural language processing, are critical in detecting suspicious messages. Simultaneously, employee training and increased awareness of cybersecurity can significantly reduce the success rate of phishing attempts. The importance of organizational culture is particularly emphasized in targeted attacks, such as spear phishing, where individual behavioral patterns are exploited. The study concludes that organizations should integrate technological and human-centered approaches to enhance their cybersecurity. Recommendations include implementing comprehensive training programs, utilizing advanced technologies, and fostering a strong security culture. These measures can significantly reduce the risk of phishing attacks and improve organizations' resilience against modern cyber threats.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-02-27T07:28:37Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-02-27T07:28:37Z (GMT).
