2014: The year of cybersecurity
We are the moles!
What we know so far…
Based on heuristic-systematic processing model (HSM) (Chen & Chaiken, 1999)
Heuristic processing: bypass in-depth thinking and instead rely on heuristics, rules of thumbs, past experience, and instincts (for efficiency)
Systematic processing: scrutinize all elements and aspects of information presented (for accuracy)
Based on protection motivation theory (PMT) (Rogers,1975)
Severity
Vulnerability
Response efficacy
Self-efficacy
Protection enactment
What we know so far…
The integrated model
• 288 students• A simulated phishing email disguised to originate
from the university’s student ID card office. • The phishing email requested the participants to
provide personal information to update their credit card information
The experiment
The results
Theoretical implication: • It is one of the few studies that applies the PMT framework to an
email phishing context• The incorporation of both PMT and HSM
Practical insights: • Fear drives protection and more mindful internet behavior• Skills/knowledge (self-efficacy) matters
Takeaway
