Information security risks have become a significant concern for users of computer information technology. However, users' behavior of acceptance and actual use of available information security solutions has not been commensurate with the level of their information security concerns. Traditional technology acceptance theory (TAM) emphasizes the factors of perceived usefulness and perceived ease of use in acceptance of technology. There has been little research focus and consensus on the role of knowledge in user adoptions of information security solutions. This paper proposes a new and adapted model of technology acceptance that focuses on the relationship between users' knowledge of information security and their behavioral intention to use information security solutions. This study employs a survey method that measures users' knowledge of information security and their attitude and intention toward using information security solutions. Statistical analysis of the results indicates a positive correlation between user knowledge of information security and user intention to adopt and use information security solutions.
