User authentication and detection of malicious actions
Abstract
Modern devices can carry out potentially dangerous actions, such as storing corporate and personal data, performing electronic transactions, accessing health data, and many more. All these actions introduce the ability to securely access increasingly personal information, which, in fact, raises the problem of user authentication. The usage of passwords introduces critical security issues due to their predictability, while tokens are not resistant to malware attacks, such as key loggers and memory scrapers.These issues can only be addressed by holistically investigating the problem of user authentication. The security of online accounts is drastically affected by the password predictability, as well as the parameters for password storage. Therefore, we propose a mathematical model, based on the parameters that influence password security. The main goal is to discover the cost of password guessing. Moreover, an extended survey of the default password storage parameters indicates that a s ...
