The raise in online platforms and services that organizations around the world offer has grown significantly, ensuring the information security of these platforms is a task of paramount importance. There are challenges in achieving this mainly due to the shortage of skilled security professionals and the growing number of online services that companies offer. This article focuses on the benefits of using Crowdsourcing security programs, such as Vulnerability Disclosure Programs (VDP) and Bug Bounty programs to complement the existing security assessments performed by organizations. These programs provide a way for organizations to better interact with the security community, gain valuable insight into the public security posture, improve the brand image by providing a mechanism in which security researchers can notify the organizations of imminent security risks.
Although in these moments wireless routers are accessible for consumer use in public places as well as in households, from a security perspective, wireless networks pose an increased risk, not only for unauthorized access to the network, but more important for manipulating the information flow of other users on the network. Man-in-the-middle attacks enable attackers to impersonate legitimate services and intercept communications from the users in an attempt to steal sensitive information. In this paper the authors propose a solution based on embedded devices to detect attackers that manipulate the network with the scope of stealing sensitive information. This solution is based on low cost and energy efficient computers that can be connected to regular network equipment to detect and alert on malicious activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
